Abstract
The disclosure is of apparatus including a pallet load which is to be wrapped with film, the pallet and load being horizontally movable along a straight-line path from a loading area to a wrapping station. At the wrapping station, there are a fixed vertical roll of wrapping film and a movable vertical roll of wrapping film, and the film to be wrapped around the load extends, as a curtain, between the two rolls. When the pallet load is moved into the wrapping station, it is pushed into the curtain of film which partially encloses the load, and the movable roll is driven toward the fixed roll to complete the wrapping of the film about the load and to provide a region where two layers of film overlap each other. With the load thus completely enclosed, a clamping bar secures the seal area, and a heat-sealing device is used to seal the overlapping layers of film to complete the wrap. The film is then cut in the seal area, the movable roll is returned to its starting position to re-form the curtain of film, and the wrapping operation is ready to be repeated.
