The sheet is continuously heated and pulled away from the side, being wound onto a roll. An Independent claim is included for the corresponding equipment. This includes the winding unit (12A) moved along the wall with a driven winder (14), its axis parallel to the wall, and a heating system (13A) moved with it. Preferred features: During pulling of a two-layer sheet, following heating the outer layer is pulled away from the inner, and wound up. The layers are wound up at differing speeds. The sheet is heated externally by infra red radiation. This radiation has a wavelength matched with the energy absorption of the adhesive layer. The sheet may be warmed by turbulent flow heating from the rear. Before, after or simultaneously, contact heat is applied with the radiation. The sheet is heated over a large area.
