Abstract (en)
A process for the continuous winding, with an automatic cycle, of thermoplastic film in bobbins of a chosen size directly from the film production apparatus or from large bobbins, wherein the wound bobbin (3), by means of automatic operations, is unloaded from the working seat (after cutting the film being wound), the spindle (2) of the cardboard core-spindle assembly is deflated of air, the bobbin (3) is removed from the spindle (2) and the spindle (2) is inserted in a new cardboard core and then inflated with air in order to rigidly couple the cardboard core with the spindle (2), and finally the new cardboard core-spindle assembly, after spraying onto the cardboard core a film of glue for the adhesion of the film, is placed in standby, waiting to be inserted in the working seat in order to begin the winding of a new bobbin . <IMAGE>
