This is heated and applied to the sections of sheet (4) used to cover the sides of the bed. An Independent claim is included for a system for carrying out the above method in which an application device (1) containing a heater (10) is positioned between a sheet supply roll (2) and a product winding roll (3) and applies weighting material (18) to the sheet as it passes over a support (8).
