In addition, while utilizing the advantage of the vacuum suction bar with less bag mistakes compared to a purely mechanical clamp, the weakness of the bag's supporting force, which is a drawback of this bar, is compensated for by the presser claws. The mouth is bent at right angles to the corners of a pair of vacuum suction bars and pressed down to increase the friction between the bar and the bag, so that even a heavy-weight packaging bag subjected to centrifugal force due to the rotation of the rotor can slip off the bar. Prevent and ensure product management.
