Abstract (en)

[origin: FR2823190A1] The invention relates to improvements to methods for recharging a machine which is used to pack groups of products (1, 2, 3, 4) with the aid of a plastic film (5; 51; 53) wherein the film (51) of a distributor reel (7) is unwound, the film of a full reel (70) is subsequently engaged into injection means (17) in such a way that said reel (70) becomes a distributor reel in turn, then the empty distributor reel (7) is replaced with a new full reel. According to the invention, while a reel (7) is being distributed, the full reel (70) is placed in the machine and the free end (52) of the film connected to said full reel is maintained in a waiting position; when it is detected that the end of the film of the distributor reel (7) has reached a predetermined position, the advance of the film (7) of said reel is halted and the free end (52) of the film (53) connected to the full reel (70) is driven in such a way that it becomes a distributor reel; while said full reel (70) is being distributed, the empty distributor reel (7) is replaced by a new full reel and the free end of the beginning of the film connected to said new reel is maintained, whereupon the previously mentioned cycle is resumed with a new reel when the final extremity of the film of the full reel (70) which is being distributed reaches a predetermined position in the machine.

[origin: FR2823190A1] The procedure for re-loading a machine fed by an injector mechanism with a film cutter consists of fitting a stand-by roll of wrapping film in the machine while a previous roll is being used and placing the free end of the stand-by roll in readiness inside the injector/cutter. Once the end of the film from the previous roll reaches a given position it is stopped and replaced by the free end of the stand-by roll's film. The procedure for re-loading a machine used for wrapping batched of products (1-4) in plastic film (5) fed by an injector mechanism (17) with a film cutter consists of fitting a stand-by roll (70) of wrapping film in the machine while a previous roll (7) is being used and placing the free end (52) of the stand-by roll in readiness inside the injector/cutter. Once the end of the film from the previous roll reaches a given position in the machine it is stopped and replaced by the free end of the stand-by roll's film. The old roll (7) is then removed from the machine and replaced by a fresh stand-by roll, so that the wrapping procedure can operate continuously.
