摘要:
A method and apparatus is provided for cutting an elastomeric laminate that may include a layer of reinforcement cords, into a desired length without cutting through the cords. The method includes the step of cutting through the gum portion of the elastomeric composite material at a desired skive angle, and then opening up the skived cut. Next, the cord reinforcement layer is cut without severing the reinforcement cords. An elastomeric composite strip cut to the desired length is produced and has cut ends. One of the cut ends has the gum portion cut at a desired skive angle adjacent an overhang portion of the reinforcement layer. The opposite end of the elastomeric composite segment also has a skived portion to mate with the skived portion of the first cut end, and a gap in the cord ply to mate with the cord overhang of the first end, resulting in a splice. An improved anvil having independently controlled vacuum zones is also provided, as well as improved cutting mechanisms.
