Abstract
The invention comprises a low modulus power transmission belt having a multi-unit cord tensile member. The belt also comprises a low modulus elastomeric body. A multi-unit cord tensile member configuration is plied into the elastomeric body, the tensile cord members having an included angle in the range of 120° to 180° between each ply. The belt having an elastic modulus of less than 1,500 N/mm and having an elongation of approximately 6.8% over a load range of approximately 0-350 newtons.
