Abstract

A method of securing an end cover (10) to a tubular body (18) involves forming the cover (10) with a flange (12) whose outer peripheral margin (14) is curled back on itself and forming the body (18) with a frusto-conical flange (20) whose larger end is smaller in diameter than the inner extremity of the curl (14). The cover (10) is seated on the flange (20) and pressure is applied via the cover to deflect the flange (20) downwardly thereby bringing its outer peripheral margin into registry with a groove (16) afforded by the curl (14) and also rendering the flanges (12, 20) generally parallel. Thereafter the flanges (12, 20) are rolled together to form a triple seam.
