ABSTRACT:
A core for an elastomeric tubing assembly is produced from a ribbon helically wound on itself to form a cylindrical tube. The edges of the ribbon are formed to interlock with each other and are contoured to facilitate ultrasonic welding of the edges. A support member is coextruded in the ribbon to provide increased resistance to premature collapse of the tube.
