    摘要: 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 (2) with an engaging roller (4), disengaging with a take-off roller (3), and applying and fusing the cords (7) to the profile layer at a desired cord spacing there between. The cord (7) may be fused by melting the profile layer surface with a heated plow and/or with heated cord. The cord (7) is then covered with the top layer material (10) 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.
