PCT No. PCT/DK96/00132 Sec. 371 Date Sep. 29, 1997 Sec. 102(e) Date Sep. 29, 1997 PCT Filed Mar. 29, 1996 PCT Pub. No. WO96/30270 PCT Pub. Date Oct. 3, 1996A method of seaming a circular cover panel (1) provided with a turnable pull ring (2) onto the body of a can. The cover panel comprises a circumferential score line (5) as close as possible to the rim portion (6) of said panel. The pull ring (2) on the cover panel used is mounted in a non-radial position on said cover panel (1) with the result that a clearance (a) is provided between the rim portion (6) of the cover panel and the nose (3) of the pull ring, and a clearance (b) is provided between the rim portion (6) of the cover panel and the handle part (2) of the pull ring. As a result, a closing chuck can be inserted in these clearances (a, b) during the seaming of the cover panel. In this manner the seaming operation is very simple and very rational because it is not necessary to use a particular closing chuck, and because the cover panel need not be angularly positioned on the seaming machine before the closing chuck and the cover panel are moved towards each other.
