ABSTRACT:
An apparatus and method for folding one or more continuous single or multiple ply webs wherein the webs are guided generally downwardly by an oscillating arm that oscillates fore and aft about a horizontal transverse axis relative to the direction the web travels, and directed by the oscillating arm alternately between opposed folding assemblies. The folding assemblies have a plurality of gripper means which travel continuously about a preselected path and receive the web at locations where the folds are to occur, then grip and thus fold the web, and thereafter release the web allowing it to exit downwardly in a folded configuration. The apparatus and method possess high speed capabilities in providing a parallelogram linkage for driving the oscillating arm and by timing the gripper means of the folding assemblies to close more rapidly and grip the web fed thereto by the oscillating arm. At any instant of time, at least three web folds are gripped at each folding assembly for superior web control as the folded web moves downwardly.
