Abstract: A trimming apparatus comprises a conveying device, a movable upper knife, an immovable lower knife, a movable press crosshead, a first drive, and a control unit. The print product is pressed down with the press crosshead. The pressed down print product is trimmed with the upper and lower knives. The press crosshead is lifted following the step of trimming operation. Subsequent to lifting the press crosshead, the upper knife is lifted. The trimmed print product is conveyed with the conveying device.

Abstract: An apparatus for producing a bound print item from unbound printed products supplied in a straddling position to be stitched with wire staples comprises a conveying device with a support that is slanted toward the side and consists of individual elements. The conveying device includes carriers for the synchronized transfer of the printed products to an intermediate conveyor that is installed upstream of a stitching section. The transfer region between the conveying device and the intermediate conveyor is provided with a side-mounted, synchronously operated support plate which has a recess along the circumference to which the carriers are allocated.

Abstract: Apparatus to separate web parts from a continuous web and feed them in zig-zag fashion onto a stack. Arranged at the sides of stack are holding-down elements designed in the manner of a paddle. These holding-down elements are moved along an elliptical path in such a way that they execute a movement directed downwards and laterally outwards towards the sides of the stack. In this movement, they come into contact in the region of the folding locations with the material web parts, be they individual sheets or longer parts to be folded in a zigzag form and press the engaged region of the material web parts downwards and outwards towards the sides of the stack. In this way, a satisfactory fold is formed at the respectively correct location, even in the case of material web sections which have neither been prefolded nor provided with lines of weakness beforehand. Also, a process for forming web parts, feeding them to a stack, and pressing them down as described.

Abstract: Apparatus for forming a stack of zigzag folding paper by feeding a web of cross-perforated paper from below through an oscillating gap onto the upper strands of bands, said apparatus having length-compensating means whereby the lengthening of the upper strand of one band powers the means for compensating for the increase in the length of the lower strand of the other band.
