A device for guiding a bar at the outlet of a lathe feeder, particularly of an automatic lathe comprising: a tubular body (5), which is fixed to the outlet of the feeder (3) coaxially to the rotation axis (A) of the bar; and a plurality of circular annular elements (11), which are mutually adjacent and lie on planes which are perpendicular to the bar rotation axis (A) and are articulated inside the tubular body (5) about axes which are angularly distributed around the axis and so that the center of the elements can oscillate along a circular path which passes through the axis; the elements have respective arms (13) which protrude outside the tubular body through slots of the body and are articulately coupled to a sleeve (16) which is supported so that it can rotate on the tubular body (5); the sleeve (16) is controlled by an actuation (20) which turns it in both directions, so as to produce an oscillation of the elements in a position which forms a passage for the bar which is delimited by portions of the circular annular elements (11). <IMAGE> |
