摘要： According to an example aspect of the present invention, there is provided a method and apparatus for folding a stack of superposed sheets. The method comprises transferring the stack to a folding station, gripping a first part of the stack with a first grip and forming a crease on the stack to facilitate the folding. Then the at least a part of the stack is folded over the first part of the stack that has been gripped by utilizing the crease, the folded stack is gripped with a second grip and the folded stack is transferred from the folding station to a next handling stage and releasing the first grip.

摘要： A sheet processing apparatus that can suppress a reduction in a quality of a finish of a fold part of a stack of center-folded sheets without losing an ease of center-folding. The sheet processing apparatus comprises a creasing unit for forming a folding stripe on a sheet so as to facilitate folding the sheet, and an acquisition unit for acquiring information related to a thickness of the sheet. One or more sheets to be provided with folding stripes are determined, from among a plurality of sheets to be folded, according to the information related to the thickness of the sheets, and each of the determined one or more sheets are provided with a folding stripe.

摘要： In a saddle-stitching apparatus, when a sheet is transported to a center-folding unit, a folding blade moves from a retrieved position to a nip position between a pair of folding rollers. A forward end of the folding blade comes into contact with a fold of the sheet, so that the sheet is folded along the fold. When the sheet is attached to the nip position between the folding rollers, the folding rollers start rotating and then, the folding blade inserts the center-folded sheet between the folding rollers. After the center-fold finishing is completed, the rotations of the folding rollers stop in timing at which the folding blade is pulled out of the nip position between the folding rollers. When pulling the folding blade out of the nip position between the folding rollers, the rotations of the folding rollers restart.

摘要： A sheet processing apparatus includes two pressing members and an advancing-receding unit. The pressing members nip and press against a fold section of a sheet. The advancing-receding unit causes the pressing members to repeatedly press against the fold section by causing at least one of the pressing members to advance to and recede from the other pressing member. The advancing-receding unit varies a reception separation amount and a post-receding separation amount from each other and sets the post-receding separation amount to be smaller than the reception separation amount. The reception separation amount is a separation amount by which the pressing members are separated from each other when the fold section is to be received between the pressing members. The post-receding separation amount is a separation amount by which the pressing members that have pressed against the fold section are separated from each other after receding from the fold section.
