IMPROVED ROLLER AND METHOD OF MAKING SAME Abstract of the Disclosure A commercial roller which includes an improved preformed roller cover and a central core is described wherein the preformed cover incorporates a novel inner sleeve support member having an extended surface area for providing increased adhesion and reduced bonding failure both with respect to an outer elastomeric cover and to the inner core. The novel inner sleeve has a corrugated construction on both the interior and exterior surfaces thereof providing a series of alternating interior and exterior channels which increase the surface area available for chemical bonding and also provide positive mechanical barriers to assist bonding and reduce bond failure. The roller can be assembled at point of use by mounting the improved preformed roller cover onto the central core.
