Abstract: A bar feeder for a machine tool, comprising a first guide and first pushing member for feeding bars in alignment with a spindle of the machine. A second bar guide and a second pushing member are laterally arranged to the first pushing member. A drive slidably moves the pushing members in a feeding direction of the bars. The first pushing member and second pushing member conjointly with the second bar guide are reciprocally alignable with the first guide. A programmable control unit (PLC) sequentially actuates the pushing members in an aligned condition with the first guide to forward a bar and insert it in a spindle maintaining an inoperative condition of the machine, and to forward by steps the bar along the spindle at each working cycle of the machine.
