Abstract:
A system and method of making an open-ended, reinforced, layered belt having a profile layer, a top layer material, and tensile cords fully encapsulated there between. The method includes engaging portion of the profile layer on a rotatable cylindrical mandrel with an engaging roller, disengaging with a take-off roller, and applying and fusing the cords to the profile layer at a desired cord spacing there between. The cord may be fused by melting the profile layer surface with a heated plow and/or with heated cord. The cord is then covered with the top layer material in a lamination step involving heating to melt at least a portion of the top layer and pressing it to fuse it to the reinforced profile layer. Lamination may be done downstream or directly on the mandrel.
