Abstract
In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.
