Abstract
A roll of material, e.g., thermoplastic ribbon comprises a hollow core made of a plastic strip of which the ends are mutually joined by overlapping, and the core's outer surface facing the material to be wound being of a nature opposing slippage of the material on it. The plastic strip includes an adhesive-coated foil of which the adhesive-fitted surface forms the outer core surface facing the material. The first winding layer facing the core bonds to this core and, as a result, the finished roll is made mechanically strong and this strength can be enhanced by an adhesive-coated plastic foil tautly enclosing the outside of the roll and fitted with a projecting, adhesive free or adhesive-neutralized tear-open tab.
