ABSTRACT:
Individual separated pouches are supplied to the inlet station of an endless continuously-moving carrier provided with adjustable pouch-supporting mechanisms at uniform intervals therealong. Each mechanism supports the pouch adjacent the opposite upper corners thereof. The pouch is moved past an opening station which fully opens the pouch mouth. The pouches are continuously moved through a filling station having plural material-guiding funnels which are rotatably supported and move at the same speed as the pouches when positioned thereover. A control mechanism, synchronized with the pouch carrier, lowers opposed spring-urged fingers into the pouch mouth to center same under the funnel and securely hold same open. Thereafter the guide funnel is lowered into the open mouth and material is deposited through the funnel into the pouch. The funnel and fingers are then raised out of the pouch. The pouch and its supporting mechanism then passes into a tensioning station which stretches the pouch mouth and also effects heating thereof. The filled pouch then passes through a sealing station which heat seals the pouch mouth, whereupon the support mechanism releases the pouch.
