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.
