Abstract: A method of joining two ends of belting having a layer of cover material and an embedded longitudinal reinforcement structure which is longitudinally compressible comprising removing the cover material from the reinforcement structure a short distance from each end of the belting, placing uncovered reinforcement structure ends in end-to-end relationship, and applying a substantially weftless fabric having a compression absorbing warp material so that the warp members are parallel to the length of the belting and the fabric layer overlies the ends, applying cover material and setting or vulcanizing the assembly.

Abstract: Belting having a layer of covering material and a compression resistant longitudinal reinforcement structure the belting being formed with a joint region at which ends of the reinforcement structure are in end-to-end relationship with a layer of jointing fabric overlying the ends of the reinforcement structure and positioned with warp members of the jointing fabric lying parallel to the length of the belting, the jointing fabric having a high tensile strength in the warp direction and sufficient crimp or twist to absorb compressive force in the warp direction.

Abstract: The invention relates to a method of bonding certain aromatic polyamide to nitrile rubber compositions by applying to an aromatic polyamide a coating of a vinyl chloride polymer, preferably as a latex or plastisol, assembling the coated aromatic polyamide with the rubber composition and vulcanizing the rubber in contact with the coated aromatic polyamide. Preferably both the coating and rubber composition contain aldehyde condensation resin-forming ingredients or a partially condensed aldehyde resin. The reinforced composites produced are useful in hose, belting or tires.
