Patent ID: 8171704

Claim:
A device for finishing packets having respective over-wrappings of heat-shrink material, the device comprising: feed means for feeding at least a first and at least a second packet along a first and second parallel feed paths respectively to a work station through a sealing station and a heat-shrink station, each of the at least first and at least second packet has a respective lateral surface, said lateral surfaces of the at least first packet and at least second packet are superimposed along the first and second parallel feed paths; a sealing unit located at the sealing station to seal the over-wrappings about respective packets; a heat-shrink unit located at the heat-shrink station to heat the over-wrappings so that the over-wrappings shrink and adapt to the configuration of the packets, the heat-shrink unit comprising at least one heating member interposed between the first and second feed paths; and means for cooling the superimposed lateral surfaces of the first and second packets before said lateral surfaces of the first and second packet are brought into contact with each other, the means for cooling is located downstream from the heat-shrink station.
