ABSTRACT:
An endless belt particularly adapted for use in high speed power transmission, commonly termed a fan belt, which is particularly adopted to be readily formed on site to any desired length and methods and apparatus for forming the belt. The belt is comprised of an outer length of flexible and durable polymeric material having a longitudinally channel extending therethrough spaced closer to the inner surface of said belt than the outer surface thereof and a reinforcing ribbon of a flexible and durable material inserted into the channel within the outer length of material through a radial slit extending from the outer surface of the outer length of material to the longitudinal channel therein. A portion of the reinforcing ribbon within said channel extends across the abutting ends of the outer length of material and overlaps a second portion of the ribbon within the channel and is bonded thereto by an adhesive. The overlapping portions of the ribbon within the outer length of material span at least one-quarter and more preferably one-half of the circumference of the belt, and maintain the structural integrity of the belt.
