ABSTRACT:
Paint rollers are formed in a continuous process. A plastic material is delivered from pellets or powder to an extruder and then, directly from the extruder to an internally cooled mandrel. The heat of the extrusion process provides the sealing temperature between the fabric cover and the plastic strip. No additional heat source is required to soften the surface of the core. The method incorporates single extrusion or tandem or co-extrusion techniques in fabricating paint rollers where an additional layer of tacky plastic material is bonded to the surface of a base layer of plastic material to enable the fabric cover to adhere to the roller.
