Abstract
A reinforced belt assembly or construction which utilizes a reinforcing material comprised of a reinforcing member portion possessing a high Young's modulus discontinuous throughout the length of the reinforcing material and a carrier member portion extending the length of the reinforcing material. The carrier member portion facilitates transport and winding of the reinforcing material about a forming mandel during manufacture and facilitates cutting of the belt assembly from the cured reinforced sleeve material such that the high Young's modulus member does not emerge from the cut sidewalls of the belt assembly.
