Abstract: An all synthetic corrugator belt seam for joining corrugator belt sections constructed of a multi-layer fabric wherein each of the ends of the fabric is separated by removing intermediate CMD and MD yarns to form separated upper and lower fabric end portions and securing a seam tape between the separated layers at each end of the belting. The seam tape is sandwiched between the separated layers and completely enclosed therein when the layers and seam tape are secured together so that interruption of the otherwise continuous belting is minimized.
