ABSTRACT:
A stacking system for thermoplastic film products, such as polyethylene bags or the like. The stacking system is arranged to be employed in combination with a product conveyor which receives finished articles or products from a thermoplastic film converting machine, the arrangement employing stacking wheels disposed along the terminal portion of the conveyor, and wherein the drive means for the stacking wheels are arranged to impart rotary motion to the stacking wheels in timed relationship to the movement of thermoplastic film product therethrough, and with means being provided to intermittently retard the rotational velocity of the stacking wheels at a point generally coincident with the passage of the trailing edge of the film product through the stacking wheels so as to frictionally retard the rate of speed of travel of the film product.
