Abstract
An improved tuck roll apparatus includes a drive roll, backup roll and tuck roll driven by clutch for tensioning and driving a pouch web without slippage on said rolls and for feeding the web to a filler wheel of a pouch filling machine. The tuck roll apparatus drives and tensions the web directly from the vertical sealer and upstream web supply of a pouch forming, filling and sealing machine without requiring any other web drive between the sealer and the filler wheel. All drive slippage is accommodated in the clutch driving the rolls, and not by slippage between the web and the rolls.
