Abstract

The shrink wrapping machine has feed belt conveyor with perforations which correspond to the dimensions of the vacuum hood. The plastic film is draped over the objects after being supplied from feed rollers over the top of the hood. The heated thermoplastic film is transferred to the objects at the same time as the vacuum is applied inside the hood. The movement of the objects is effected by means of hydraulic jacks which carry the film forward at the same rate. The machine is also provided with loading and unloading stations.
