Title: SUPPORT ROLLER FOR RETREAD TIRE MANUFACTURING
Abstract:
A support roller (10) for use in an adhesive application stage for retread bands (12) is provided that has an outer surface with an engagement zone (16) configured for engagement with a tread surface (22) of the retread band (12). The engagement zone (16) is free from contact with an underside surface of the retread band onto which adhesive is applied. At least one groove (28) is located within a width (34) of the tread surface and extends from the tread surface (22) towards the underside surface (24). The outer surface (14) in the engagement zone (16) has a diameter size that corresponds to a profile of the tread surface across the width of the tread surface. The diameter size of the outer surface in the engagement zone does not correspond to a profile of the at least one groove across a width of the at least one groove.
