Abstract (en)
An automatic winding machine to be combined with a continuous extrusion plant of a plastic film (F) includes a motor-driven winding roller (M) on which the film (F) passes and a cutting unit (T) parallel to the roller (M) and rotatable therearound, the cutting unit (T) including a blade (L) to cut transversely the film (F) and also a blowing bar (S) connected to a source of pressurized fluid and controlled by a valve in order to push the terminal edge (E) of the film (F), cut by the blade (L), so that it winds up on a new winding core (A). This novel structure of the cutting unit (T) provides for an automatic change of the complete reel (C) both when the winding takes place in the usual direction with the film (F) passing over the roller (M) and when the winding takes place in the reverse direction with the film (F) passing under the roller (M). <IMAGE>
