ABSTRACT:
The formation of a tubular web in a form-fill process is achieved by drawing the web along a tapering guide (6) and then along a forming tube (20) the axis of which is at a small angle to the guide plate and intersects the guide. The web is drawn along the guide and tube by opposed drive rollers (24) at a station along the length of the forming tube, the rollers gripping the edges of the web together. The side margins of the web are folded over from a central portion when the web travels along the guide plate but the side edges are brought together only after they reach the forming tube. The drive rollers (24) or sealing rollers (26) further along the forming tube seal the edges together to form a closed tube.
