ABSTRACT:
A folding device for printed continuous webs moving at a high rate of speed. The device includes a pair of cooperating rolls between which the web passes. The rolls carry "working boxes" on the surfaces thereof to perform various folding functions on the moving web. Here the function of concern is the gripping of the web. An element on one roll causes the web to be pushed into open gripping elements on the cooperative roll. A bight is formed in the web at the position of gripping. During the concurrent rotation of the rolls the grippers close on the formed bight. Subsequently it is desired to remove the bight from the opening gripping elements. Simultaneously with the opening of the gripping elements there is provided a positive means for raising the formed bight out of the scope of the jaws. This bight stripper prevents any unnecessary entanglements of the fast moving printed web with the gripping elements during the folding of the web.
