Patent ID: 6962639

Claim:
A method of forming a power transmission belt/belt sleeve, said method comprising the steps of: placing a reinforcing fabric against an unvulcanized rubber layer; forming the reinforcing fabric and unvulcanized rubber layer against a mold surface having alternating grooves and projections to produce a cog pad having first and second spaced ends and cog crests and cog troughs alternating between the first and second spaced ends, each cog crest having oppositely facing side surfaces with an apex between the oppositely facing side surfaces; processing the cog pad at the first end of the cog pad so that a part of the fabric layer projects beyond the rubber layer at the first end of the cog pad; processing the reinforcing fabric at the second end of the cog pad to expose the rubber layer; joining the rubber layer at the first and second ends of the cog pad; overlapping the part of the reinforcing fabric at the first end of the cog pad with the reinforcing fabric at the second end of the cog pad so that a) a free end of the part of the reinforcing fabric at the first end of the cog pad is at a side surface on a crest and b) a free end of the reinforcing fabric at the second end of the cog pad is on the cog crest; and combining the cog pad with at least one additional component to define a power transmission belt/belt sleeve having a length.
