Abstract

The method of manufacturing tubing, comprising forming a longitudinally extending groove next to an edge of a strip of material, arranging a piece of bonding material in the groove, compressing and flattening the marginal portions of the strip to reduce the marginal portions. Of the strip to a smaller thickness than the middle part of the strip, use the operation of compressing and flattening the marginal portions to securely embed and simultaneously condense the joint material only within the confines of the slot, forming the strip as a tube with the marginal portions reduced in coating ratio so as to form a longitudinally extending seam, apply heat to the assembly so as to melt and expand the bonding material for a predetermined period of time sufficient to allow the flow of bonding material from the groove to the edges of the seam, and then stop the further flow of bonding material by cooling into the tube.
