Abstract: A control device for feeding metal bars to a multispindle automatic lathe comprises a rotating drum which bears a plurality of bar pushers 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 for each bar pusher, said motor being fixed to said rotating drum. Fluid under pressure is fed selectively to at least one or more of said hydraulic motors, depending on the feed requirements, through a unit which comprises a distributor designed to place in communication fluid delivered under pressure with said at least one or more motors during rotation of the drum to which it is constrained.

Abstract: An apparatus for feeding bars to a machine tool, in particular a multispindle lathe, comprising a plurality of pairs of opposed arrays of respectively stationary and movable jaws extending radially from a rotary drum, wherein the movable array of each pair can be distanced from the opposed, stationary array through the intermediary of a control system.The stationary arrays are formed of side-by-side sets of jaws extending radially in one piece from respective central hubs fitted onto the drum and there locked against rotation, whereas the movable arrays are secured to radial tongues swing-mounted on axles carried by the stationary arrays. The control system for the movable arrays is, on the contrary, carried by sets of radial tongues extending from respective central hubs which are also fitted and locked to the drum between the sets of jaws.
