Top Form Sack Feeder
The approaching sack operates the Topforms automatic cycle. Two blades enter the sack, the leading blade accurately positions the top of the sack and the trailing blade stretches the sack to the required width. The sack is then fed forward into the sealer or stitcher at the same speed as the conveyor. This action gives very precise presentation with minimal setting up time.The easy speed of the Topform is achieved by the blades moving with the sack then returning at high speed to pick up the next one, up to 15 Sacks per minute are possible.
