ABSTRACT:
Apparatus for aligning a wicketer frame with an edge of a tubular or semitubular plastic web. The positions of the edges of the web are sensed and the wicketer frame is transversely displaced in response to and in dependence on the sensed deviation of the edges of the web from an initial position. The wicketer frame is provided with at least one transverse rail, which is supported on rollers or sliding surfaces of an underlying carrying frame to permit transverse movement of the wicketer frame relative to the web. The wicketer frame is connected by a beam to an end frame, which carries the downstream end of a stacking conveyor and is supported on a base frame. The end frame is longitudinally displaceable and is rotatable through a small angle relative to the base frame. A rack and pinion arrangement is provided for transversely moving the wicketer frame.
