Abstract: An improved pouch-filling machine includes a pouch-opening apparatus for opening with closure strips such as zipper type locks in a continuous operation. The pouches are supported by continuously moving carriers, and the pouch-opening apparatus includes first and second stages wherein the first stage performs a preliminary opening of the upper edges of the pouch to permit gripping of the upper edges in the second stage. After this preliminary opening, the carrier carries the pouch to the second stage wherein a gripper arrangement grips and pulls the upper pouch edges outwardly to open the zipper lock. Further, the machine includes a transfer conveyor which continuously feeds the pouches to the pouch-opening apparatus in a vertical orientation.

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.
