[0001]The present invention relates to a method for knitting manufactured
articles with circular knitting machines, particularly with
high-fineness, high-gauge circular knitting machines.
[0002]Knitting machines for hosiery or the like capable of transferring a loop of knitting from the needle that formed it to a contiguous needle are known. A machine of this kind is disclosed, for example, in WO-02/070799.
BACKGROUND OF THE INVENTION
[0003]Up to now, this technique for transferring loops of knitting has been used mainly to obtain openwork in manufactures. Examples of application of this technique for openwork are disclosed in WO2005/080653 by the same Applicant.
[0004]Methods for knitting shaped manufactures with circular knitting machines are also known which are based on increasing the number of active needles in certain regions of the manufacture. Techniques of this kind suffer the drawback of allowing only to increase the active needles and therefore require starting the knitting of the manufacture from its side that must be knitted with a minimum number of needles. This fact limits the knitting processes that are possible and the shapes that can be obtained with this technique.
SUMMARY OF THE INVENTION
[0005]The aim of the present invention is to provide a method for knitting manufactured articles or manufactures with circular knitting machines, particularly with high-fineness circular knitting machines, which by using the technique of transferring the loop of knitting from one needle to a contiguous needle allows to obtain particular shaping effects of the manufacture and/or aesthetic effects.
[0006]Within this aim, an object of the invention is to provide a method which can be used also to reduce the consumption of thread in certain regions of the manufacture in order to avoid wasting raw material.
[0007]Another object of the invention is to provide a method which can be used to obtain shaping or aesthetic effects on manufactures produced with circular machines of high fineness, ranging preferably substantially from 16 to 50 needles per inch.
[0008]This aim and these and other objects, which will become better apparent hereinafter, are achieved by a method for knitting manufactured articles with circular knitting machines, particularly with high-fineness circular knitting machines, characterized in that at least once during the formation of the manufacture, the number of active needles is reduced by transferring the last loop of knitting formed by certain needles to contiguous needles and thus excluding from knitting such certain needles during the formation of at least one subsequent row of knitting by the needles that are kept active.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019]With reference to FIGS. 1 to 3, the method according to the invention consists substantially in that at least once during the formation of the manufactured article or manufacture, the number of active needles is reduced by transferring the last loop of knitting formed by certain needles to contiguous needles. After the transfer of the loop of knitting, these needles are excluded from knitting, while the other needles continue to form knitting at the subsequent feeds or drops of the machine.
[0020]FIG. 1 illustrates a portion of a manufacture obtained with the method according to the invention. For the sake of simplicity, the illustration of the portion of the manufacture has been limited to the knitting of eight needles, whose rows of knitting have been designated by the reference numerals 1 to 8. The formation of the portion of knitting proceeds from the bottom upwardly in FIG. 1.
[0021]According to the invention, after providing a first region of knitting A, using substantially all the needles of the machine, except for any variations of the active needles due to pattern requirements, a region of knitting B is produced by using half of the needles used to form the region of knitting A. This reduction of the active needles is obtained, according to the invention, by causing in a per se known manner, for example as provided in WO-02/070799 (see FIGS. 8 and 9), the transfer of the last loop of knitting formed by the needles that form the rows 1, 3, 5, 7 to the needles that form the rows 2, 4, 6, 8 and then continue knitting by forming the region of knitting B.
[0022]The needles N excluded from knitting are kept retracted within the needle cylinder Cy, below the casting-off plane formed by the sinkers S, so as to not interfere with the work of the other needles N or of the other elements of the machine.
[0023]Owing to the fact that the region of knitting B is knitted with a smaller number of needles and therefore is composed of a smaller number of loops of knitting, greater transparency and/or reduced stretchiness of the knitting is obtained at such region of knitting B. Moreover, again for this reason, at said region the manufacture contracts. In this manner it is possible to achieve shaping of the manufacture.
[0024]The shaping effects and/or the transparency effects on the manufacture that can be obtained with the method according to the invention are several and can be alternated with each other, since at any time after the formation of the manufacture it is possible to resume knitting with at least some of the needles previously excluded from knitting.
[0025]FIG. 3 illustrates a portion of a manufacture produced with the method according to the invention by excluding from knitting, in a certain step of the knitting process, certain needles, in a manner similar to what has been described with reference to FIG. 1, and by resuming, in a subsequent step, knitting with the needles previously excluded from knitting. In FIG. 3 also, for the sake of simplicity, the illustration of the portion of manufacture has been limited to the knitting of eight needles, whose rows of knitting have been designated by the reference numerals 1 to 8. The formation of the portion of knitting proceeds from the bottom upwardly in FIG. 3.
[0026]More particularly, after providing a first region of knitting A by using substantially all the needles of the machine except for any variations of the active needles due to pattern requirements, a region of knitting B is produced by using half of the needles used to form the region of knitting A. This reduction of the active needles is obtained, according to the invention, by causing, in a per se known manner, the transfer of the last loop of knitting formed by the needles that form the rows 1, 3, 5, 7 to the needles that form the rows 2, 4, 6, 8 and then continue knitting by forming the region of knitting B.
[0027]The needles of the rows 1, 3, 5, 7 that had been excluded from knitting are then made to knit again, forming, together with the other needles, a region of knitting A which is similar to the region of knitting A that had been formed before the needles of the rows 1, 3, 5, 7 were excluded from knitting.
[0028]It should be noted that for the sake of simplicity in description it has been assumed that during the formation of the region B one needle out of every two contiguous needles is excluded from knitting, but the number of needles excluded from knitting may change according to the requirements. It is in fact possible, by means of the repeated transfer of a loop of knitting and optionally of loops of knitting received previously from a contiguous needle, to exclude from knitting two needles out of every three, or three needles out of every four, and so forth. FIG. 2 illustrates a region B produced by excluding from knitting, by means of repeated transfers of loops of knitting from one needle to a contiguous needle, four needles out of every five contiguous ones. In this figure, for which the same numbering as in FIGS. 1 and 3 has been kept, after a certain number of rows of knitting, required to transfer the loops of knitting from the needles to be excluded from knitting to a contiguous needle, the needles that form the rows of knitting 1, 3, 4, 5, 6, 8 are gradually excluded from knitting, while the needles that form the rows of knitting 2 and 7 continue to knit.
[0029]Likewise, the needles previously excluded from knitting may all be returned to work, or only some of the needles previously excluded from knitting may be returned to work, according to the requirements.
[0030]Moreover, although the needles excluded from knitting are preferably uniformly spaced from each other, they may also be arranged at mutually different distances. For example, in the formation of a same row of knitting there may be regions of row knitted by one needle out of every two contiguous ones and regions of row knitted by one needle out of every three contiguous ones and/or regions of row knitted by one needle out of every four contiguous ones, et cetera.
[0031]In this manner it is possible to obtain regions of the manufacture with diversified transparencies and shaping effects which can vary according to the requirements.
[0032]Moreover, it should be noted that since the regions B are knitted with a smaller number of needles, they require a smaller amount of thread to be manufactured. It is therefore particularly advantageous to provide as regions B the regions of the manufacture that are meant to be cut and discarded during the finishing step of the manufacture, as will become better apparent hereinafter.
[0033]Merely by way of example, FIG. 4 illustrates an undershirt 10, which can be manufactured with the method according to the invention.
[0034]The undershirt 10 is preferably manufactured starting from the lower edge 11 and by providing, in a per se known manner, almost all the undershirt up to the region of the neck 12, for example by making all the needles of the machine knit, with allowance for any need to vary the active needles in order to produce patterns and for any cutting of the threads in order to provide armholes. In practice, the entire undershirt 10, except for the region of the neck 12, can be provided like the region A described above with reference to FIGS. 1, 2, 3.
[0035]The neck region 12 is manufactured by reducing the number of active needles. The number of active needles is reduced, according to the invention, by transferring the last loop of knitting from the needles that must be subsequently excluded from knitting to the contiguous needles. In practice, the neck region 12 can be provided like the region B described above with reference to FIGS. 1, 2, 3.
[0036]In this manner, the neck region 12 is highly shaped and narrow with respect to the remaining part of the manufacture, obtaining an excellent fit for such region.
[0037]FIG. 5 illustrates a tubular intermediate, semifinished, manufacture 20 for providing a body suit, in which the regions 21, 22, 23, 24, 25, 26 meant to be removed during the finishing step of the knitted manufacture are marked.
[0038]In this case, nearly all the manufacture can be provided like the region B described above with reference to FIGS. 1, 2, 3, i.e., by using a reduced number of needles. In this manner it is possible to obtain a transparency effect on the entire item, the use of thread is reduced particularly for producing the regions that are meant to be subsequently removed, and it is possible to obtain shaping effects in the various regions of the manufacture to be produced.
[0039]The transparency and shaping effect of the manufacture can be obtained, as explained above, by varying, even on a same row, the number of needles used to produce the different regions of the manufacture.
[0040]Specific regions of the manufacture requiring greater consistency and/or reduced transparency and/or an increase in the circumferential dimensions of the manufacture, such as for example the regions of the cups of the bra 27, can be provided by increasing the active needles used to produce these regions with respect to the needles used to produce the remaining part of the manufacture. Substantially, the regions 27 can be provided like the regions A described above with reference to FIGS. 1, 2, 3.
[0041]FIGS. 6a, 6b illustrate the front side and the rear side of a tubular intermediate manufacture 30 for producing a pair of underpants. The intermediate manufacture is preferably obtained by starting production from the belt region 31 and by producing the regions 32, 33, which are meant to be removed during the finishing step of the manufacture, with a reduced number of needles, for example like the regions B described above with reference to FIGS. 1, 2, 3, while the remaining part 34 of the manufacture is produced by using substantially all the remaining needles of the machine, for example like the regions A described above with reference to FIGS. 1, 2, 3, with allowance for variations of the active needles for obtaining pattern effects and/or open-knit/open-work and/or ladderproof knitting structures.
[0042]This reduces the amount of thread for providing the regions 32, 33 meant to be removed.
[0043]FIGS. 7a, 7b illustrate the front side and the rear side of a tubular intermediate manufacture 40 for producing a pair of underpants, with regions 42, 43 which are meant to be removed during the finishing step of the manufacture.
[0044]Preferably, the tubular intermediate, semifinished, manufacture 40 is obtained by starting production from the belt region 41. The manufacture is produced by using, for most of its production, all the remaining needles of the machine, for example such as the regions A described above with reference to FIGS. 1, 2, 3, with allowance for variations of the active needles in order to obtain pattern effects and/or open-knit and/or ladderproof knitting structures. Optionally, the regions 42, 43 meant to be removed during the finishing step of the manufacture may be provided with a reduced number of needles, for example like the regions B described above with reference to FIGS. 1, 2, 3.
[0045]At preset regions 44, 45, such as for example the front central region and/or the peripheral region of the buttocks, for which transparency effects and/or effects of reduced stretchiness are to be obtained in order to achieve containment and/or shaping and/or support effects, knitting is performed by using a reduced number of needles, for example as in the production of the regions B described above with reference to FIGS. 1, 2, 3.
[0046]Substantially, in the examples described above, the transition from knitting with a certain number of needles (region A) to knitting with a reduced number of needles (region B) is obtained, according to the invention, by transferring the last loop of knitting formed by the needles that must then be excluded from knitting to the contiguous needles that instead must continue knitting. Any transition from knitting with a reduced number of needles (region B) to knitting with a larger number of needles (region A) is achieved simply by returning to work at least part of the needles previously excluded from knitting.
[0047]It should be noted that the method according to the invention is meant to be used preferably in circular knitting machines having a fineness or gauge ranging from 16 to 50 needles per inch, obtaining high-fineness manufactures with transparency and/or shaping effects never obtained before on these finenesses.
[0048]In the examples of embodiments described above, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other examples of embodiments.
[0049]In practice it has been found that the method according to the invention fully achieves the intended aim, since by using the technique of transferring the loop of knitting from one needle to a contiguous needle in order to reduce the active needles it allows to obtain particular shaping effects of manufactures and/or aesthetic transparency effects and/or savings in thread, even on high-fineness manufactures.
[0050]The method thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may further be replaced with other technically equivalent elements.
[0051]In practice, the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019]With reference to FIGS. 1 to 3, the method according to the invention consists substantially in that at least once during the formation of the manufactured article or manufacture, the number of active needles is reduced by transferring the last loop of knitting formed by certain needles to contiguous needles. After the transfer of the loop of knitting, these needles are excluded from knitting, while the other needles continue to form knitting at the subsequent feeds or drops of the machine.
[0020]FIG. 1 illustrates a portion of a manufacture obtained with the method according to the invention. For the sake of simplicity, the illustration of the portion of the manufacture has been limited to the knitting of eight needles, whose rows of knitting have been designated by the reference numerals 1 to 8. The formation of the portion of knitting proceeds from the bottom upwardly in FIG. 1.
[0021]According to the invention, after providing a first region of knitting A, using substantially all the needles of the machine, except for any variations of the active needles due to pattern requirements, a region of knitting B is produced by using half of the needles used to form the region of knitting A. This reduction of the active needles is obtained, according to the invention, by causing in a per se known manner, for example as provided in WO-02/070799 (see FIGS. 8 and 9), the transfer of the last loop of knitting formed by the needles that form the rows 1, 3, 5, 7 to the needles that form the rows 2, 4, 6, 8 and then continue knitting by forming the region of knitting B.
[0022]The needles N excluded from knitting are kept retracted within the needle cylinder Cy, below the casting-off plane formed by the sinkers S, so as to not interfere with the work of the other needles N or of the other elements of the machine.
[0023]Owing to the fact that the region of knitting B is knitted with a smaller number of needles and therefore is composed of a smaller number of loops of knitting, greater transparency and/or reduced stretchiness of the knitting is obtained at such region of knitting B. Moreover, again for this reason, at said region the manufacture contracts. In this manner it is possible to achieve shaping of the manufacture.
[0024]The shaping effects and/or the transparency effects on the manufacture that can be obtained with the method according to the invention are several and can be alternated with each other, since at any time after the formation of the manufacture it is possible to resume knitting with at least some of the needles previously excluded from knitting.
[0025]FIG. 3 illustrates a portion of a manufacture produced with the method according to the invention by excluding from knitting, in a certain step of the knitting process, certain needles, in a manner similar to what has been described with reference to FIG. 1, and by resuming, in a subsequent step, knitting with the needles previously excluded from knitting. In FIG. 3 also, for the sake of simplicity, the illustration of the portion of manufacture has been limited to the knitting of eight needles, whose rows of knitting have been designated by the reference numerals 1 to 8. The formation of the portion of knitting proceeds from the bottom upwardly in FIG. 3.
[0026]More particularly, after providing a first region of knitting A by using substantially all the needles of the machine except for any variations of the active needles due to pattern requirements, a region of knitting B is produced by using half of the needles used to form the region of knitting A. This reduction of the active needles is obtained, according to the invention, by causing, in a per se known manner, the transfer of the last loop of knitting formed by the needles that form the rows 1, 3, 5, 7 to the needles that form the rows 2, 4, 6, 8 and then continue knitting by forming the region of knitting B.
[0027]The needles of the rows 1, 3, 5, 7 that had been excluded from knitting are then made to knit again, forming, together with the other needles, a region of knitting A which is similar to the region of knitting A that had been formed before the needles of the rows 1, 3, 5, 7 were excluded from knitting.
[0028]It should be noted that for the sake of simplicity in description it has been assumed that during the formation of the region B one needle out of every two contiguous needles is excluded from knitting, but the number of needles excluded from knitting may change according to the requirements. It is in fact possible, by means of the repeated transfer of a loop of knitting and optionally of loops of knitting received previously from a contiguous needle, to exclude from knitting two needles out of every three, or three needles out of every four, and so forth. FIG. 2 illustrates a region B produced by excluding from knitting, by means of repeated transfers of loops of knitting from one needle to a contiguous needle, four needles out of every five contiguous ones. In this figure, for which the same numbering as in FIGS. 1 and 3 has been kept, after a certain number of rows of knitting, required to transfer the loops of knitting from the needles to be excluded from knitting to a contiguous needle, the needles that form the rows of knitting 1, 3, 4, 5, 6, 8 are gradually excluded from knitting, while the needles that form the rows of knitting 2 and 7 continue to knit.
[0029]Likewise, the needles previously excluded from knitting may all be returned to work, or only some of the needles previously excluded from knitting may be returned to work, according to the requirements.
[0030]Moreover, although the needles excluded from knitting are preferably uniformly spaced from each other, they may also be arranged at mutually different distances. For example, in the formation of a same row of knitting there may be regions of row knitted by one needle out of every two contiguous ones and regions of row knitted by one needle out of every three contiguous ones and/or regions of row knitted by one needle out of every four contiguous ones, et cetera.
[0031]In this manner it is possible to obtain regions of the manufacture with diversified transparencies and shaping effects which can vary according to the requirements.
[0032]Moreover, it should be noted that since the regions B are knitted with a smaller number of needles, they require a smaller amount of thread to be manufactured. It is therefore particularly advantageous to provide as regions B the regions of the manufacture that are meant to be cut and discarded during the finishing step of the manufacture, as will become better apparent hereinafter.
[0033]Merely by way of example, FIG. 4 illustrates an undershirt 10, which can be manufactured with the method according to the invention.
[0034]The undershirt 10 is preferably manufactured starting from the lower edge 11 and by providing, in a per se known manner, almost all the undershirt up to the region of the neck 12, for example by making all the needles of the machine knit, with allowance for any need to vary the active needles in order to produce patterns and for any cutting of the threads in order to provide armholes. In practice, the entire undershirt 10, except for the region of the neck 12, can be provided like the region A described above with reference to FIGS. 1, 2, 3.
[0035]The neck region 12 is manufactured by reducing the number of active needles. The number of active needles is reduced, according to the invention, by transferring the last loop of knitting from the needles that must be subsequently excluded from knitting to the contiguous needles. In practice, the neck region 12 can be provided like the region B described above with reference to FIGS. 1, 2, 3.
[0036]In this manner, the neck region 12 is highly shaped and narrow with respect to the remaining part of the manufacture, obtaining an excellent fit for such region.
[0037]FIG. 5 illustrates a tubular intermediate, semifinished, manufacture 20 for providing a body suit, in which the regions 21, 22, 23, 24, 25, 26 meant to be removed during the finishing step of the knitted manufacture are marked.
[0038]In this case, nearly all the manufacture can be provided like the region B described above with reference to FIGS. 1, 2, 3, i.e., by using a reduced number of needles. In this manner it is possible to obtain a transparency effect on the entire item, the use of thread is reduced particularly for producing the regions that are meant to be subsequently removed, and it is possible to obtain shaping effects in the various regions of the manufacture to be produced.
[0039]The transparency and shaping effect of the manufacture can be obtained, as explained above, by varying, even on a same row, the number of needles used to produce the different regions of the manufacture.
[0040]Specific regions of the manufacture requiring greater consistency and/or reduced transparency and/or an increase in the circumferential dimensions of the manufacture, such as for example the regions of the cups of the bra 27, can be provided by increasing the active needles used to produce these regions with respect to the needles used to produce the remaining part of the manufacture. Substantially, the regions 27 can be provided like the regions A described above with reference to FIGS. 1, 2, 3.
[0041]FIGS. 6a, 6b illustrate the front side and the rear side of a tubular intermediate manufacture 30 for producing a pair of underpants. The intermediate manufacture is preferably obtained by starting production from the belt region 31 and by producing the regions 32, 33, which are meant to be removed during the finishing step of the manufacture, with a reduced number of needles, for example like the regions B described above with reference to FIGS. 1, 2, 3, while the remaining part 34 of the manufacture is produced by using substantially all the remaining needles of the machine, for example like the regions A described above with reference to FIGS. 1, 2, 3, with allowance for variations of the active needles for obtaining pattern effects and/or open-knit/open-work and/or ladderproof knitting structures.
[0042]This reduces the amount of thread for providing the regions 32, 33 meant to be removed.
[0043]FIGS. 7a, 7b illustrate the front side and the rear side of a tubular intermediate manufacture 40 for producing a pair of underpants, with regions 42, 43 which are meant to be removed during the finishing step of the manufacture.
[0044]Preferably, the tubular intermediate, semifinished, manufacture 40 is obtained by starting production from the belt region 41. The manufacture is produced by using, for most of its production, all the remaining needles of the machine, for example such as the regions A described above with reference to FIGS. 1, 2, 3, with allowance for variations of the active needles in order to obtain pattern effects and/or open-knit and/or ladderproof knitting structures. Optionally, the regions 42, 43 meant to be removed during the finishing step of the manufacture may be provided with a reduced number of needles, for example like the regions B described above with reference to FIGS. 1, 2, 3.
[0045]At preset regions 44, 45, such as for example the front central region and/or the peripheral region of the buttocks, for which transparency effects and/or effects of reduced stretchiness are to be obtained in order to achieve containment and/or shaping and/or support effects, knitting is performed by using a reduced number of needles, for example as in the production of the regions B described above with reference to FIGS. 1, 2, 3.
[0046]Substantially, in the examples described above, the transition from knitting with a certain number of needles (region A) to knitting with a reduced number of needles (region B) is obtained, according to the invention, by transferring the last loop of knitting formed by the needles that must then be excluded from knitting to the contiguous needles that instead must continue knitting. Any transition from knitting with a reduced number of needles (region B) to knitting with a larger number of needles (region A) is achieved simply by returning to work at least part of the needles previously excluded from knitting.
[0047]It should be noted that the method according to the invention is meant to be used preferably in circular knitting machines having a fineness or gauge ranging from 16 to 50 needles per inch, obtaining high-fineness manufactures with transparency and/or shaping effects never obtained before on these finenesses.
[0048]In the examples of embodiments described above, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other examples of embodiments.
[0049]In practice it has been found that the method according to the invention fully achieves the intended aim, since by using the technique of transferring the loop of knitting from one needle to a contiguous needle in order to reduce the active needles it allows to obtain particular shaping effects of manufactures and/or aesthetic transparency effects and/or savings in thread, even on high-fineness manufactures.
[0050]The method thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may further be replaced with other technically equivalent elements.
[0051]In practice, the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
[0052]The disclosures in Italian Patent Application No. MI2005A001189 from which this application claims priority are incorporated herein by reference.
[0053]Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
