An apparatus for feeding bars (2) to a lathe comprises a first end (4) couplable with a spindle of the lathe; stationary means (6) for guiding and supporting a bar (2) in a first region (R1), the stationary means (6) extending along a longitudinal axis (L) from a second end (5) to an intermediate zone (I) between the first end (4) and the second end (5); a drum element (8) that extends between the first end (4) and the intermediate zone (I), is rotatable around a rotation axis (X) parallel to the longitudinal axis (L); movable supporting means (9) provided on the drum element (8) for supporting a bar (2) parallel to the longitudinal axis (L) in a second region (R2) adjacent to the first region (R1) and extending between the intermediate zone (I) and the first end (4); the movable supporting means (9) are slidably drivable along the drum element (9) parallel to the rotation axis (X) between a contracted disengagement configuration (C), in which the movable supporting means (9) are collected near the first end (4) to enable a bar (2) to be positioned on the stationary guiding and supporting means (6), and an extended engagement configuration (E), in which they are distributed between the first end (4) and the intermediate zone (I) to engage with the respective bar (2) to be supported and guided. |
