摘要： A machine (1) for producing packages of napkins, tissues, towels, or similar products, comprises a support frame (100) to support a feeding group (10) which feeds a first and a second web of paper (5a, 5b). The support frame (100) supports, furthermore, a cutting group (20) which cuts the first and second webs of paper (5a, 5b) respectively in a first and a second plurality of sheets (6) of predetermined length, and a folding or interfolding group (30) which folds or interfolds the sheets of paper (6) at a folding or interfolding zone, (35) in such a way to obtain a stack (150) of folded or interfolded sheets, according to a predetermined folding or interfolding configuration. The cutting group (20) and the folding or interfolding group (30) are mounted on the same support body (110) to move between an assembled position in which is supported by the support frame (100), and a disassembled position, in which is not supported by the support frame (100). A displacement group (50) is, furthermore, provided to displace the support body (110) between the assembled position and the disassembled position. The displacement group (50) and the support body (110) are provided with respective engagement portions (58,118) to engage with each other in such a way to allow the displacement group (50) to displace the support body (110) between the assembled position and the disassembled position

摘要： According to one embodiment, a sheet processing device includes a folding unit and a fold-enhancing unit. The folding unit folds a sheet and thus forms a fold line thereon. The fold-enhancing unit includes a fold-enhancing roller, an opposite member, and an auxiliary roller. The fold-enhancing roller moves along a fold-line direction in which the fold line on the sheet formed by the folding unit extends. The opposite member sandwiches the fold line with the fold-enhancing roller. The auxiliary roller rolls over the sheet from the same side as the fold-enhancing roller. The auxiliary roller is displaced in a unified manner with the fold-enhancing roller in the fold-line direction and the direction of the thickness of the folded sheet. A drag torque generated by the movement of the fold-enhancing roller in the fold-line direction is higher in the auxiliary roller than in the fold-enhancing roller.

摘要： An apparatus for folding and receiving book documents comprises a main conveying device arranged and adapted to convey unfolded book documents in a main conveying direction and a secondary conveying device arranged and adapted to receive the book documents conveyed by the main conveying device and to convey them in a secondary conveying direction and/or against the secondary conveying direction, wherein the secondary conveying direction is transverse to the main conveying direction. Further, the apparatus comprises a receiving device arranged at a spatial distance from the first and/or the second conveying surface and configured to receive folded book documents. The device folds the conveyed book documents respectively with a movement in the secondary conveying direction and/or against the secondary conveying direction. Furthermore, a lifting device is arranged to convey the folded book documents from the main conveying device and/or from the secondary conveying device into the receiving device.

摘要： A postprocessing device performs postprocessing on sheets received from an image forming apparatus. The postprocessing device includes a pair of folding rollers, a folding blade, a transport device, a drive portion, and a drive controller. The drive controller controls the drive portion to match moving speed of a tip portion of the folding blade with moving speed of a circumferential surface of the folding rollers, at a time point that the sheaf of the sheets makes contact with the circumferential surface of the folding rollers, when the image forming apparatus forms the image by ink jet printing, and to match the moving speed of the tip portion of the folding blade with the moving speed of the circumferential surface of the folding rollers, at a time point that the sheaf of the sheets reaches the nip region between the folding rollers.

摘要： A sheet folding device includes a sheet conveyance path, first and second side plates, a first folding roller pair, a first folding guide, and a guide drive mechanism. The first folding guide is reciprocatable between a folding position and a retracted position, and includes a guide main body and first and second arms provided respectively at both ends of the guide main body. The guide drive mechanism includes a drive source provided on the first side plate, a first drive transmission portion that transmits a drive force of the drive source to the first arm, a second drive transmission portion that transmits the drive force to the second arm, and a drive coupling portion that couples the first drive transmission portion to the second drive transmission portion and transmits the drive force from the first drive transmission portion to the second drive transmission portion.

摘要： To prevent displacement of first fold positions and collapse of discharged and stacked sheets when sheet fold processing is performed a plurality of times for each sheet. First fold processing is applied to a sheet conveyed to a conveying path by a rotating body pair 22. The sheet that has been subjected to the first fold processing is fed back to the conveying path while a first fold line is being opened. Then, second fold processing is applied to the sheet that has been fed back to the conveying path by the rotating body pair 22. The resultant sheet is discharged with the first fold line opened.

摘要： A sheet separation device to open a two-ply sheet includes a rotator; a nipping member disposed opposite the rotator and configured to nip the two-ply sheet with the rotator; a conveyor configured to convey the two-ply sheet between the rotator and the nipping member, and a winding member disposed adjacent to the rotator. The conveyor conveys the two-ply sheet with a bonded portion of the two-ply sheet being an upstream end or a downstream end of the two-ply sheet in a conveyance direction of the two-ply sheet. The winding member winds the two-ply sheet around the rotator, to create a difference in winding circumferential length between the two sheets and separate the two sheets.

摘要： Embodiments of the present invention provide new and improved folding apparatuses and methods for interfolding a continuous stream of sheets into a single-fold interfolded pattern of sheets while passing all of the sheets substantially along a single sheet path. More particularly, all sheets in the continuous stream of sheets pass through the nips between adjacent components.
