Abstract:
A method for covering a metal roll core with a polymeric material, said method comprising the steps of:providing a cylindrical roll core, the roll core having two ends, a length, and an outer surface;placing the roll core in a substantially vertical orientation such that the roll core has a top end and a bottom end;helically winding a length of mold tape from the bottom end to the top end of the roll core in a spaced-apart relationship with the roll core outer surface to define an application zone between the inside surface of the mold tape and the roll core outside surface;extruding a filament of a polymeric material within the application zone and helically winding the filament onto the roll core outer surface from the roll core bottom end to the top end thereof,allowing the wound polymeric material to cool to form a continuous polymeric layer over the roll core outer surface;removing the mold tape.
