ABSTRACT:
A process for manufacturing helically corrugated pipe coupling gaskets is provided wherein a sheet of rectangular flexible gasket material is extruded having parallel corrugations on one side, cutting the sheet across the corrugations at an angle which is the complement of the helix angle of the pipe, and then bonding opposite ends of the cut strip to form a circumferentially continuous strip.
