| 20100075821 | METHOD AND MACHINE FOR FOLDING SHEETS - A folding machine and a method of folding sheets of paper, board and the like with underlapping, include at least a first folding station with folding units and an imbricated feeder for feeding sheets to the first folding station, over an aligning table, in a first transporting direction. The imbricated feeder has a device for separating the sheets and a suction configuration which can be adjusted in and counter to the first transporting direction and is intended for the underlapping transfer of sheets from a sheet stack of the imbricated feeder to the aligning table. | 03-25-2010 |
| 20110136644 | SHEET FOLDING APPARATUS AND IMAGE FORMING APPARATUS USING THE SAME - A sheet folding apparatus includes: a fold roller pair which forms a nipping portion and inserts the center of a sheet bundle into the nipping portion to form a fold in the sheet bundle; a folding blade which moves from a standby position and presses the center of the sheet bundle against the nipping portion when the fold is formed, and returns to the standby position after the pressing of the nipping portion is completed; and a protection member which prevents an access to a front edge of the folding blade in a longitudinal direction of the front edge when the folding blade is located at the standby position. | 06-09-2011 |
| 20120202671 | FOLDING MACHINE HAVING A DEVICE FOR TRIMMING FOLDED EDGES AND METHOD OF FOLDING SHEETS - A folding machine for folding sheet-like elements includes at least a first buckle-folding station, a second buckle-folding station and possibly a further buckle-folding station, for respectively forming folding configurations having at least one fold. A folded edge trimming device is provided upstream of a respective folding station, for removing the at least one previously-formed fold. A method of folding using such a folding machine is also provided. It is thus possible to generate folded products with a high level of folding accuracy. | 08-09-2012 |
| 493420000 | Buckle chute folding | 8 |
| 493421000 | Plural folding operations making multiple folds | 8 |
| 20080214377 | SHEET PROCESSING APPARATUS AND IMAGE FORMING DEVICE HAVING THE SAME - There is provided a sheet processing apparatus, when a bundle of sheets subjected to the stapling process is folded into two to make a book, for pressing the fold, thereby improving the look. | 09-04-2008 |
| 20090062097 | Z-FOLDING APPARATUS AND SHEET PROCESSING APPARATUS - A Z-folding apparatus of an embodiment of the invention includes a pair of feed rollers to transport a sheet along a specified transport passage, a contact portion with which a head of the transported sheet comes in contact, a press member to press a specified position of the sheet apart from the head, and a pair of folding rollers to form a fold line on the sheet and to transport the sheet on which the fold line has been formed. When the head of the sheet comes in contact with the contact portion, the press member presses the specified position of the sheet apart from the head in a transport direction toward the pair of folding rollers, and guides it to a nip between the rollers of the pair of folding rollers. | 03-05-2009 |
| 20090275455 | Informational Item Forming Method - A method of using a folding apparatus to form an outsert having product information printed thereon comprises making a plurality of folds in a first direction in a sheet of paper; making a plurality of folds in a second direction perpendicular to said first direction to form folded articles; making a fold in said second direction to form an outsert; and applying pressure to at least one of said folded articles or said outsert, said pressure being at least about 30 pounds per square inch, said pressure being applied by a pressing unit comprising a plurality of pressure rollers. | 11-05-2009 |
| 20090275456 | INFORMATIONAL ITEM FORMING METHOD - A method of using a folding apparatus to form an outsert having product information printed thereon comprises making a plurality of folds in a first direction in a sheet of paper; aking a plurality of folds in a second direction perpendicular to said first direction to form folded articles; making another fold in said second direction to form an outsert including causing a movable member of a folding apparatus to make contact with and move an intermediate portion of a folded article towards a pair of adjustably-spaced folding members, at least one of said adjustably-spaced folding members having a position that is adjustable to allow said adjustably-spaced folding members to be adjustably spaced apart from each other by a distance that is within a range defined by a lower boundary of 0.25 inches and an upper boundary of 0.45 inches. | 11-05-2009 |
| 20100016138 | SYSTEM AND METHOD FOR PRODUCING A CROSS-FOLD IN FOLDED SHEET MATERIAL - A cross-fold system for use in combination with a device for folding sheet material and includes a rigid guide structure having a stationary reaction surface for supporting and guiding folded sheet material along a feed path between a sheet feed mechanism and a tensioning mechanism. Furthermore, the cross-fold system includes a paper break assembly disposed between the sheet feed mechanism and the tensioning mechanism. The paper break assembly, furthermore, includes an abrasion bar disposed transversely of the feed path and in opposed relation to the rigid guide. Moreover, the paper break assembly is repositionable from an active position to an inactive position such that, in the active position, the abrasion bar pressingly engages the sheet material against the stationary reaction surface of the guide assembly, and, in the inactive position, the abrasion bar permits the sheet material to pass to the tensioning mechanism without engaging the sheet material. When the paper break assembly is in the active position, the tensioning mechanism is operative to pull the folded sheet material across the abrading bar to yield the adhesive bond between the reinforcing fibers of the sheet material. As such, a subsequent cross-fold of the folded sheet material is facilitated. | 01-21-2010 |
| 20100069214 | Outsert-Forming Method - A method and apparatus for forming informational items such as outserts and booklets may include (a) folding a sheet of paper having product information printed thereon by making a plurality of folds in the sheet of paper to form a first folded article; (b) making a plurality of folds in the first folded article in a second direction perpendicular to the first direction; and (c) making a final fold in the second direction to form an outsert using a folding apparatus having a pair of adjustably-spaced folding rollers having a nip therebetween and a movable blade member, with the folding rollers spaced apart by a distance within a range of 0.25 inches and 0.45 inches. Water scoring may be used to facilitate folding of the sheet of paper. | 03-18-2010 |
| 20100137119 | Paper Folding Station - A paper folding station with a paper-feeder and a first pair of motorized rollers supported at a delivery end of the paper-feeder about respective parallel axes to draw sheets of paper from the feeder. One of the rollers is mounted on a first adjustable support. A folding buckle is provided to receive the sheets from the first pair of rollers through an inlet mouth. The buckle has a barrier causing the sheets to stop and bend into the shape of a groove below the inlet mouth. A second pair of rollers is supported near the inlet mouth about respective parallel axes to pinch the groove and to make a transverse fold on the sheet. The paper-folding station further comprises at least one transverse beam to guide the sheet near the inlet mouth. | 06-03-2010 |
| 20120004085 | SHEET FOLDER - A sheet folder comprising input rollers, exit rollers and a fold box having a fold plate which is curved substantially along its whole length, wherein the curved fold plate is configured to induce a sheet to curve in two different directions during the folding process. | 01-05-2012 |
