ABSTRACT:
A continuous running paper web is folded in zig-zag formation at a stacking station to form a pile of superimposed panels which are joined to each other by weakened fold lines. A stack containing a preselected number of superimposed panels at the bottom of the pile is moved laterally away from the stacking station so that the topmost panel of the stack or the lowermost panel of the remainder of the pile is unfolded, and the web is broken between such panels by tearing it along a weakened fold line or by severing it from one marginal portion to the other marginal portion along a weakened fold line or across one of the panels. The part or parts which move the stack from the stacking station can include or constitute the web breaking device. The remainder of the pile is supported from below during removal of the stack from the stacking station.
