Abstract: Bar feeder (1) comprising a guide channel (10) centred on an invariable guide axis (A-A), characterised in that the guide channel (10) is adjustable and is formed by an adjustable guide element which can define a guide channel with a constant centre (C) corresponding to a bar diameter comprised between a maximum bar diameter (DMax) in a first position (P1) and a minimum bar diameter (DMin) in a second position (P2) under the action of a device for adjusting the diameter of the guide channel (2).

Abstract: Installation for sequential loading of bars of material, referred to as bars, in a functional subassembly of a machine for machining these bars, the installation including an elongated element, referred to as pusher, which has a front end, and is placed under the control of a first device, the pusher including at least one first part which has the front end and a second part that is connected to the first device and these two parts.

Abstract: An installation for sequential loading of bars of material in a machining center includes a frame, a first device, and a second device. The frame includes at least one first arcuate bearing surface and at least one second arcuate bearing surface connected to the first bearing surface at a first station. The first device includes a first elongated body having a peripheral first face engaging the at least one first bearing surface and a plurality of first longitudinal cavities in the first face. The first elongated body is configured to rotate such that the first bearing surface blocks an opening of the first longitudinal cavities between a first position where a bar is loaded into the first longitudinal cavity and a second position where a bar exits the first longitudinal cavity at the first station.

Abstract: Installation for the sequential loading (1) of bars of material, referred to as bars (2), into a machining center (4), this installation including in particular a frame (5) and being characterized in that it is equipped: with a first device (700) which is, on the one hand, constituted by a first elongated body (7), the volume of which is substantially determined by a peripheral surface, referred to as first face (70), and comprising a plurality of first longitudinal cavities (71) which are each able to accommodate a bar (2) and each include a first opening (72) made in said first face (70), on the other hand, is able to carry out a fractional rotation about a first axis (73), aligned longitudinally, particularly carrying bars (2), so as to present the first cavities (71) in sequence to at least one first station (8), with a second device (900) which is, on the one hand, constituted by a second elongated body (9), the volume of which is substantially determined by a peripheral face, referred to as the s
