Abstract (en)
The present invention aims to provide a pusher used in packaging equipment improved so that undesirable deformation of articles to be packaged can be effectively prevented. A pusher 1 used in the packaging equipment includes a head unit 36 provided in its frontal end wall 46 with an air supply port 53 and in lateral walls 43 with air suction ports 52. The air supply port 53 is adapted to maintain fluid-communication between inside and outside of an envelope 2b as long as the frontal end wall 46 of the pusher 1 stays inside the envelope 2b. The air suction ports 52 are adapted to suck an amount of air inside the envelope 2b as the frontal end wall of the pusher 1 moves away from inside of the envelope 2b and thereby allow the open end of the envelope 2b to be formed with the gussets 57.
