Abstract
A roll wrapping machine includes a roll infeed conveyor; a roll wrapping station having a film curtain, sealing bars and a pusher for pushing the roll into the curtain and past the bars; and a roll orienter on the infeed conveyor. The orienter receives each roll fed down the conveyor, spins the roll and releases the roll with the roll tail in a known circumferential location so that the tail of the roll is in the six o'clock position when the roll is received at the wrapping station and is not caught between the plastic curtain film during sealing.
