BAG FORMING AND FILLING MACHINE

摘要

The bag filling and forming machine employs a chute for conveying a flow of loose fill material, a form for enveloping a sheet of plastic film about the chute, a heat-seal roller for sealing the overlapped edges of the film to form a tube and heat-seal bars for sealing the tube at spaced apart positions to form the top and bottom of bags. A pair of conveyors are provided for continuously moving the formed tube relative to the chute and fingers are provided for spreading the tube into a flattened configuration for heat-sealing purposes. A hot wire or cutting knife is provided for cutting off a filled bag after heat-sealing.
