Abstract
A bagging machine for automatically covering a loaded pallet with a bag formed from a tubing of resilient film. The tubing is fed by drive rollers down into the machine where vacuum heads grasp the sides of the tubing and spread it open. Fingers are then inserted and when an appropriate length of tubing is fed onto the fingers, a cut-and-seal mechanism cuts the tubing and seals the end of the bag. The fingers retract to further open and stretch the bag. The carriage in which the fingers are mounted is then lowered and the bag is fed onto the load.
