ABSTRACT:
A continuous web folder includes a pair of driven cylinders arranged in adjacent parallel relation, and each cylinder has a pair of diametrically opposed movable jaw members disposed at right angles to a pair of diametrically opposed pivotal tucker blades. The surface of each cylinder includes axially spaced circumferentially extending wide grooves which form relatively narrow circumferentially extending ribs therebetween for effectively eliminating the effect of static electric attraction between the cylinders and a paper web directed between the cylinders and thereby provides for high speed zig-zag folding of the web.
