Abstract: A knife folding machine comprises: a support surface (4) for supporting a lower surface of a sheet (S); a knife blade (5); a pair of folding rollers (6a, 6b) opposed to the knife blade (5) at a fold position with the support surface (4) therebetween. The knife blade (5) is reciprocated between first and second positions by a knife drive unit 7. The first position is away from an upper surface of the support surface, and the second position is adjacent a gap between the folding rollers. The reciprocal movement of the knife blade (5) effects a folding operation every time the sheet (S) is set at the fold position. The sheet (S) is conveyed to the fold position by the conveyer belt (13). The conveyer belt (13) is driven by a first servomotor (11). The control unit (12) controls the rotation of the first servomotor (11) so as to decelerate the sheet (S) before its abutment against the stopper (14) without its rebounding against the stopper (14).

A paper supply section is provided with a conveyor belt for conveying paper sheets (P) sequentially supplied from a paper sheet stack. A guide plate (4) for aligning the positions of the conveyed paper sheets is provided on a conveying surface of the conveyor belt. A paper folding section has a buckle (10) comprising an outer frame (11) and bars (12) which extend between opposite sides (11a, 11b) of the outer frame and are arranged at intervals from each other. Paper sheet introducing gaps extended in the direction of the length of the bars are provided in the buckle.

Abstract: The paper feeder comprises a first transport unit (5) to transport a sheet (S) on top of a paper stack (2) on a paper loading table (3), and a second transport unit (6) to discharge sheets transferred from the first transport unit toward a binding device. The first transport unit begins transporting the next sheet each time a sheet is discharged from the second transport unit. Image data for a specified printed portion on the first sheet in the paper stack is stored in memory (19) as reference data. A camera (14) is disposed above the paper stack and photographs a region corresponding to the specified printed portion on the topmost sheet. A control unit (18) compares the image data for the paper photographed by the camera with the reference data, and if the image data matches the reference data, the first transport unit operations are paused.
