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.
