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.
