PROCESS FOR AFFIXING A THIN WALLED PIPE BETWEEN A CONICAL RING AND A CONICAL SLEEVE, AND DEVICES FOR CARRYING OUT THE PROCESS

摘要

1. Method for achieving the fixing of at least one of the ends of a thin tube (8) between a ring (10) having a frustoconical bore and a sleeve (20) having a frustoconical external shape, with the same conicity as that of the said bore, characterized in that : - the ring (10) is fitted onto the tube (8) ; - the sleeve (20) is positioned on a chuck (100) ; - the tube (8) is fitted onto the chuck (100) allowing the end (117) of the tube to protrude beyond the sleeve (20) ; - the end (117) of the tube (8) which protrudes beyond the sleeve (20) is heated so as to cause melting thereof and the formation of a bead (15).
