ABSTRACT:
Feeder for automatic lathe, with a tube wherein the material to be machined is held by a plunger cum piston which can be moved hydraulically within the tube. The invention provides a hydraulical system connectable to the rear opening of the tube for exerting on the piston of the plunger a force directed towards the cutting tools, and also a cable or like flexible member, fixed to the rear of the plunger cum piston, which cable serves both to determine the exact position of the plunger and to pull it backwards for extracting the remaining stub when the bar has been fully machined. The cable is maintained under tension.
