ABSTRACT:
Apparatus is disclosed for removing a coating from synthetic resin products, such as an automobile bumper, to obtain improved coating removal rate and improved productivity. A resin material having a coating applied thereto is rolled between a resin-side roll and a coating-side roll which rotate at different peripheral speeds. A shear stress is applied to the interface between the resin material and the coating, thereby removing the coating from the resin material. Pressing means press the coating-side roll towards the resin-side roll with a predetermined force. The resin-side roll and the coating-side roll apply a normally fixed shear stress between the resin material and the coating, ensuring stable coating removal and improved productivity.
