A wicket type bag stacking machine is provided with apparatus for accumulating articles being stacked on a temporary stack so that stacked articles on the production stacking station can be removed. Upon removal of stacked articles from the production stacking station an empty stacking station is provided and the articles temporarily stacked on the temporary stack are positioned on the production stacking station.

Zero cycle interrupt wicket stacker

Disclosed is a mechanism, associated with a thermoplastic bag making machine, for preparing a strip of thermoplastic to produce bags having the upper edges of the bag mouth formed in a sinusodial shape such that the peak of such shape is substantially equi-distant relative to the side edges of the bag. While the disclosed bag machine is of the type that advances the web strip incrementally, shaping of the web strip in the sinusodial shape occurs while a portion of the web strip is advanced at substantially constant velocity. A mechanism is provided for maintaining constant tension in the web despite the constant and intermittent feeding of the web.

The disclosed device comprises a roller, rotatably mounted on a pivotable arm, for maintaining rolling contact with the edges of sheets being adhesively laminated. One of the sheets is rather stiff board and the other a thin gauge sheet covering one side of the board. As the laminated sheets advance the roller, which is in pressure engagement with the edges of the board parallel to the direction of movement, moves laterally inwardly to also provide rolling contact with the lateral trailing edge of the board. In doing so the corners of the thin wrap are pressed tightly against the edges of the board to produce well defined corners.
