Stangenzuführvorrichtung für Stangenschubvorrichtungen an Werkzeugmaschinen

A bar guiding device in a feeder for feeding a machine tool, composed of two elements (10,17) that have respective slots (20,21) and can move with respect to each other between an open position, which allows insertion of a bar (B) between them, and a mutually adjacent position, at which the slots form a longitudinal channel for advancement of a bar (B) to be fed to the machine tool by way of a bar pusher (27) connected to an actuation chain (29) that is external to the channel by means of a bridge (28) that is guided through regions (22,23) where the elements mate, the regions being in mutual contact, so as to close the channel, and undergoing elastic deformation in order to allow passage of the bridge between them.
