摘要： The spigot end of a tube made of hard polyvinyl-chloride (PVC) is fit into the heat-shrinkable bell end of a similar tube. A hot thermally-activatable adhesive is injected into the space between the bell and spigot so that it heats and shrinks the bell, causing it to compress and distribute the adhesive mass throughout the joint. The bell is formed with a circumferential bulge forming an inwardly opening circumferential recess into which the adhesive mass is injected through at least one radially opening hole. The mass of adhesive in this groove serves as a hot reservoir of glue during shrinking and distribution.
