ABSTRACT:
An automatic wrapping machine comprising a film roll support adapted to hold a roll of film, a turntable adapted to hold a load of unitary members positioned adjacent to the film roll support, a drive apparatus to rotate the turntable and a brake adapted to place tension on the film web of the roll of elastic stretchable material carried in the roll support. A clamp assembly is mounted adjacent to the load to hold the film while the turntable with associated load rotates allowing film to wrap around the load and the clamp assembly. The clamping assembly includes a pneumatic device for activating the clamp after the completion of at least one revolution of turntable so that the clamping assembly is retracted from the film overwrap. A film cutting and clamping mechanism is located adjacent to the turntable to cut the film web after the load is wrapped and holds the free end of the film in a secured position. The holding clamp subsequently clamps around the film to hold the same in position for the wrapping of the next load after it is in position.
