ABSTRACT:
A zig-zag folding apparatus which includes a swing chute movable in a forward and rearward direction to transmit narrow sheet material between spaced, forward and rearward folding stations. A sheet folding device is located at each of the folding stations which includes a chain carrying a series of paddles, and a drive train which rotates the chain and paddles with respect to the folding station. In the course of moving in a forward and rearward direction, the swing chute transmits the narrow sheet material into contact with beaters or knock-down fingers located at each folding station which direct the sheet into a folding position where the paddles carried by the chain operate to fold or crease the sheet material along its perforations and thus form a stack of zig-zag folded sheets.
