Abstract:
A method for producing a paint roller in a single continuous integrated operation comprising the steps of:a. initially angularly feeding a first polypropylene strip to a mandrel support member, and thereafter, with an offset from the angular feeding of the first polypropylene strip, angularly feeding a second polypropylene strip onto an outer surface of the first polypropylene strip, and angularly feeding a paint roller cover strip, onto an outer surface of the second polypropylene strip,b. after the initial feeding of the respective strips to the mandrel, moving the respectively fed strips in both a rotational direction about the mandrel and simultaneously along the length of the mandrel, while continuously applying a layer of adhesive to the first and second strips, the layer of adhesive spanning at least a portion of an exposed outer surface of a winding of the first polypropylene strip and at least a portion of an exposed outer surface of a winding of the second polypropylene strip, adjacent thereto, with the layer of adhesive not contacting an outer surface of the cover strip;wherein movement and application of the layer of adhesive to the adjacent windings of first and second polypropylene strips effects continuous adhesion between first and second polypropylene strips and between the second polypropylene strip and cover strip to continuously form the core and cover of the paint roller.
