A machine for fastening a compression ring on an object to be fastened by shrinking the ring in which segmental actuating slide members (20, 20') are movable within a housing along circular paths with a constant radius about a centre (0), and in which segments (30, 30') on the inside of the slide members are operable to move a limited distance in the radial direction; the segmental slide members are provided with internal surface portions (29, 29') of non-constant radial distance from a centre, and the segments are provided with surface portions (34) for abutment with the non-concentric surface portions on the inside of the slide members; an actuating mechanism (60, 54, 50) operatively connected with the slide members causes the latter to close and thereby forces the segments to reduce the inside diametric dimension thereof which in turn causes compression of a shrink-ring held thereat. <IMAGE> |
