Abstract

A web separator is provided that cuts a web at predetermined separation locations. Downstream of the cutting, the web is folded at predetermined fold locations. A continuously swinging director, downstream of the folding, guides advancing sections of web to opposing fold edges of a supported zig-zag stack. The web is driven into the continuously swinging director by a driving member. The driving member is deactivated selectively by a clutch, while other elements of the separator continue to operate. A central drive motor may be interconnected with each of the drive member, swinging director, folding and support elements. Fold and separation locations may be determined by a bar code detector and selectively operable upper and lower conveyor belts may be disposed below the supported zig-zag stack.
