Claim:
1. A bushing alignment device of a bar loading magazine for guiding material bars on an automatic lathe, wherein a z-axis (z) is defined by the longitudinal axis of a material bar guided in the bar loading magazine, and wherein a plurality of first bushings, which can be moved along the z-axis (z) and into which the material bar is to be inserted along the z-axis (z) for processing in the automatic lathe, are arranged in the bar loading magazine, wherein a first rotational axis, which is arranged either coaxially or parallel to the z-axis (z) and about which the first bushings are rotatably mounted, extends through the first bushings, wherein alignment between the first bushings and a cross-sectional profile of the material for inserting the material bar at a predetermined rotational position is achieved by one or more of: (i) one or more friction wheels as drive means, which for force transmission can be selectively coupled to the first bushings or decoupled therefrom by a pivoting device, to which the drive means are attached and which can be pivoted toward the first bushings for coupling thereto, and wherein the first bushings can be coupled to the drive means in a friction-fit manner and are driven by a linear motor, by a rotatorily acting motor and/or by an actuator motor, for rotatorily driving the first bushings about the first rotational axis to the predetermined rotational position, and (ii) one or more holding units, which are adapted to selectively retain the first bushings in the predetermined rotational position.
