ABSTRACT:
A V-belt and method of making the same wherein a joint between opposite ends of the rubber portion of a belt preform is offset a preselected distance from one or more joints of fabric bonded to at least one of the inner and outer surfaces of the belt. The rubber and fabric are cut in making the preform suitably to have juxtaposition of the opposite ends thereof when wrapped about a mandrel in forming a belt sleeve from which the final V-belts are formed. Where the final belts are W-belts, a similar manufacture of the outer portion of the belt is effected. The fabric-covered portion of the belt may be cogged and the preselected spacing of the rubber and fabric joints is at least the pitch of the cogs. The fabric is preferably stretchable fabric.
