ABSTRACT:
A rotary driver feeds a web containing transverse crease lines. The driver contains circumferentially spaced edges which drivingly engage the crease lines. When the crease lines are spaced farther apart than the edges, that part of the web disposed between those edges is deflected inwardly, as by a vacuum, to bring the crease lines into engagement with the edges.
