ABSTRACT:
A wick for use in forming a vacuum between a curing envelope and a tire during a tire retreading process, and a method for the manufacture of the wick. The wick is provided by a pad of rubber reinforced with a stretchable fabric material and engagable with a valve which extends through the curing envelope. The wick has a face with a pattern of grooves forming a network of gas passageways to the valve to ensure complete evacuation of all gases when the vacuum is drawn between the curing envelope and tire. The method of manufacture of the wick includes locating unvulcanized rubber and fabric material between a pair of mold dies, and closing the mold dies to form the pad and simultaneously embed the fabric within the rubber. In addition, one of the mold dies form a network of grooves in one of the faces of the pad.
