Abstract
An apparatus and process for automatically wrapping packages with a full-web or spiral overwrap. The apparatus includes a film handling assembly in which stretched film is wrapped around the load rotated by a turntable. When the load is stopped in a home position a cutting and sealing assembly is transported into the film path, engaging the film and displacing it out of its original dispensed path. Rotatable clamps mounted on the turntable are rotated upward to grab the lower portion of the stretched film web while the sealing mechanism of the assembly engages the trailing edge of the film web to hold it against the film wrap, after which a cutter blade of the assembly is extended into the film web, severing the film web so that the load can be transported off the conveyor with the sealing mechanism pressing the trailing edge of the film onto the package wrap. The sealing mechanism is retracted and the cutting and sealing assembly is transported away from the film web leaving a new leading film edge held by the turntable clamps to begin the next wrap cycle.
