Abstract

Abstract 1. A method for bonding inner and outer tubular elements to one another in a concentric position, said method comprising providing a reservoir of viscous bonding material above the inner tubular element for application to the inner wall of the outer tubular element as the same is set into place above the inner element and is lowered thereover, said reservoir being supported by a cap set upon the inner tubular element, and with said inner wall acting to confine the material present in the reservoir; supporting a peripheral reservoir of the bonding material about the outer wall of said inner element by means of a slidably mounted collar for application of the bonding material present in the peripheral reservoir; and moving the collar downwardly along the inner element by pressing the same with the descending outer element, thereby simultaneously coating the adjacent walls to be joined as the respective inner and outer elements are brought into concentric registry along their full length.
