20090272835 | Method and Machine for Forming Logs of Web Material, with a Mechanical Device for Forming the Initial Turn of the Logs - The rewinding machine includes a winding unit; a feed path of a web material; a separator device to sever the web material upon completion of winding each log; an insertion path of the winding cores towards the winding unit; a movable mechanical member to facilitate forming a first turn of web material around each winding core inserted in the insertion path. | 11-05-2009 |
20120186751 | Coreless roll of web material, machine and method for its production - A method is described for obtaining a coreless roll of web material with a first portion of web material forming an inner nucleus of the roll and a second portion of web material wound around the outside of the inner nucleus. The two portions can be separated from one another and, for that purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll between the inner nucleus and the second portion of web material. This facilitates the extraction of the inner nucleus from the outer portion of the roll. | 07-26-2012 |
20120297944 | MACHINE FOR CUTTING WEB ROLLS - The cutting machine includes at least one log feed channel; a cutting station along the feed channel, with at least one cutting blade for dividing each, log into individual rolls plus front and rear trims; a log feed device along the feed channel, including at least one rear member for pushing the logs to be cut, movable along the feed channel to push each log through the cutting station. The feed device also includes at least one front member for engaging with the log to be cut, arranged and controlled so as to engage frontally with each log, or series of rolls obtained after the log has been cut, for at least a part of its travel along the feed channel. | 11-29-2012 |
20130331249 | Machine For The Production Of Tubes And Related Method - The machine includes a forming unit with a spindle around which one or more strips of web material are wound; an adhesive applicator to apply an adhesive on at least one surface of at least one strip of web material; a feed path of the at least one strip of web material from the adhesive applicator to the forming unit. The length of the feed path can be modified according to at least one opening parameter. | 12-12-2013 |
20140000830 | METHOD AND DEVICE FOR JOINING PLIES OF PAPER | 01-02-2014 |
20140151192 | Accumulator For Paper Rolls Or Other Elongated Products And Related Method - The accumulator includes at least one pair of chains substantially parallel to each other to which cradles are connected for receiving products to be stored, the cradles being mutually spaced along the pair of chains. Each cradle is connected to the pair of chains through constraining members. On each chain at least one intermediate constraining member is arranged between two adjacent cradles connected to the chains. | 06-05-2014 |
20150191325 | MACHINE FOR CLOSING THE TAIL END OF A ROLL OF WEB MATERIAL - The machine includes a first glue-applying device for closing the tail end; and a second mechanical-closing device for mechanically anchoring the tail end of the roll to a portion of an outer turn of the web material wound on the roll. | 07-09-2015 |
20160001997 | REWINDING MACHINE AND METHOD FOR PRODUCING ROLLS OF WEB MATERIAL - The rewinding machine includes a first winding cradle, formed between a first winding roller, a second winding roller and a third winding roller and a second winding cradle formed between the first winding roller, the second winding roller and a fourth winding roller. The first winding roller and the second winding roller define a nip through which nip the winding cores, around which the web material is found, pass and the web material is fed towards a roll being formed in the second winding cradle. A severing member is furthermore provided, acting on the web material between a winding core and the nip, to sever the web material thus generating a tail edge of a completed roll and a leading edge of a new roll to be wound. | 01-07-2016 |
