Abstract: An apparatus and method for making a paint roller are disclosed. The apparatus includes a mandrel, a first core material strip feeder, a second core material strip feeder, a fabric cover strip feeder, a first heater, a second heater, a first liquid adhesive applicator and a second liquid adhesive applicator. The first core material strip feeder feeds a first strip of core material about the mandrel. The second core material strip feeder feeds a second strip of core material about the mandrel. The fabric cover strip feeder feeds a strip of fabric cover material about the mandrel and about at least one of the first and second strips of core material. The first and second heaters are actuatable between a first active state in which the first and second heaters apply heat to an outer surface of the first and second strips of core material, respectively, and an inactive state. The first and second liquid adhesive applicators are actuatable between a first active state in which liquid adhesive is applied to an outer surface of the first and second strips of core material, respectively, and an inactive state. The apparatus produces paint rollers having varying characteristics by selective actuation of the first and second heaters and the first and second adhesive applicators. In one exemplary embodiment, a controller generates signals actuating the heaters and the adhesive applicators between the active and inactive states. According to one method, heat is applied to at least one of the outer surface of the first strip and the inner surface of the second strip and liquid adhesive is applied to the outer surface of the second strip prior to wrapping the fabric cover on the second strip. According to an alternative method, liquid adhesive is applied to at least one of the outer surface of the first strip and the inner surface of the second strip and heat is applied to the outer surface of the second strip.
