Abstract: A material bar magazine for guiding material bars on an automatic lathe and a system having such a magazine and automatic lathe having at least one headstock that is displaceable along a longitudinal axis of the material bar magazine, where the material bar magazine includes a material bar-guiding channel system having a channel opening system. Further, the channel system of the material bar magazine has a first, outer guide channel and a second, inner guide channel mounted inside the first guide channel such that it can move relative thereto along the longitudinal direction, the second, inner guide channel couplable or coupled to the headstock of the automatic lathe for moving the second, inner guide channel as a result of a change in position of the headstock along a longitudinal axis of the material bar magazine in overrun condition synchronously therewith along the longitudinal axis and relative to the first guide channel.

Abstract: A material rod feeding device for feeding material rods to a machine tool, includes a magazine for stocking the material rods and a guide means into which material rods to be processed can be fed from the magazine, one at a time. The feeding direction of a material rod from the magazine into the guide means, is transversely to the longitudinal axis of the material rod in the guide means. The guide means includes a support leg and an abutment leg for providing a variably modifiable receiving channel. The support leg provides a support surface of the receiving channel that is inclined in the feeding direction and relative to the horizontal. The abutment leg is movable along the inclination relative to the support leg, so that the variably modifiable receiving channel is formed between the two legs, into which the material rod to be processed can be fed onto the support surface. The support leg together with the abutment leg is vertically movable as a whole.
