<p>A control device for feeding metal bars to a multispindle automatic lathe comprises a rotating drum (12) which bears a plurality of bar pushers (15) arranged peripherally and equidistantly from each other, control means being associated with said bar pushers. In accordance with the invention said control means consist of a hydraulic motor (13) for each bar pusher (15), said motor being fixed to said rotating drum (12). Fluid under pressure is fed selectively to at least one or more of said hydraulic motors (13), depending on the feed requirements, through a unit which comprises a distributor (16,17,31) designed to place in communication fluid delivered under pressure with said at least one or more motors (13) during rotation of the drum (12) to which it is constrained.</p> |
