Title (EN) RING TYPE CALIBRATING CAGE
(FR) CAGE DE CALIBRAGE A SEGMENTS
Abstract: front page image
(EN)A ring type calibrating-cage (40) for confining a metal container shell (3) just prior to and during seam welding. The cage (40) comprises a series of strategically located rings (45, 47, 60) through which the can body (3) is fed. These rings are of narrow width reducing friction drag and being optimally positioned to accurately hold the can body in cylindrical shape with overlapped edge portions particularly when these edge portions enter into the welding nip (57).
(FR)Cage (40) de calibrage a segments pour la mise sous forme d"un cylindre metallique (3) avant et pendant le soudage continu. La cage (40) comprend une serie de segments (45, 47, 60) dont les emplacements sont specialement etudies, le corps metallique (3) etant guide par ces segments lors de sa progression. Ces segments ont une faible surface de contact presentant un coefficient de fiction reduit et sont positionnes pour maintenir le corps metallique sous une forme cylindrique en assurant le recouvrement des bords a souder notamment lorsque ces bords a souder penetrent dans la zone de soudage (57).
