Abstract:
A method of manufacturing a paint roller comprising the steps of:providing at least two strips of non-plastic base material;extruding a coating of liquid thermoplastic material onto an inside surface of a first strip of the at least two strips of base material prior to winding the first strip about a mandril;extruding a coating of liquid thermoplastic material onto an inside surface and an outside surface of a second strip of the at least two strips of base material prior to winding the second strip about the mandril;winding the at least two strips of base material, after application of the liquid thermoplastic material thereto, about the mandril in a spiral manner, the liquid thermoplastic material causing the at least two strips of base material to bond forming a paint roller core; andwinding a strip of absorbent material about the core in a spiral manner, the liquid thermoplastic material applied to the outside surface of the second strip of base material prior to winding causing the absorbent material to bond to the core forming the paint roller.
