Abstract (en)

The invention relates to a device for supplying and tensioning the packaging film of a wrapping machine with a reel carriage comprising a set of rollers engaged to each other by a gearing associated to a motor where the gearing comprises pinions with different rotation speed and a connection/disconnection element that allows to link one of the pinions with the rotating shaft of one of the rollers, transferring in this way the rotation speed difference of the pinions to the rollers, which causes the stretching of the film running on the rollers and, conversely, allows to uncouple that pinion from that rotating shaft of the roller by not transferring the rotation speed of the pinions to the roller, in such a way that it does not generate stretching of the film.
