Abstract: A bar feeding device, for example for a lathe, and a process for using a bar feeding device This bar feeding device comprises: a base extending lengthwise, a channel cover extending lengthwise and rotatably connected to the base, a guiding member comprising a guiding channel extending lengthwise, a pusher flag, a mover, such as an endless chain, fastened to a first end of the pusher flag and able to move the pusher flag lengthwise, a push bar able to move within the guiding channel and fastened to a second end of the pusher flag. The channel cover comprises at least one displaceable member and an displacer for actively displacing the displaceable member relative to the channel cover.

Abstract: A bar feeder for separately feeding longitudinal bars (3, 3?) from a storage unit (1) to a transportation unit (2) is provided. The storage unit (1) comprises a delivery mechanism, which delivers bars (3) in delivery direction to the transport unit (2). The transport unit (2) comprises separated, moveable spaces (8) for accommodating the bars (3?), wherein the spaces are moveable in a transport direction. An abutment screw section is provided on the transport unit, which is moveable from a blocking position for blocking a bar (3) in delivery direction and a release position for allowing movement of the bar in delivery direction and into a space. The abutment screw section is switched between the blocking position and the release position by a rotational movement of the transport unit (2).

Abstract: The invention relates to a bar feeding device, for example for a lathe. This bar feeding device comprises:—a base (1) extending lengthwise, a channel cover (4) extending lengthwise and rotatably connected to the base (1), a guiding member (7) comprising a guiding channel (8) extending lengthwise, a pusher flag (12), a mover, such as an endless chain (13), fastened to a first end of the pusher flag (12) and able to move the pusher flag (12) lengthwise, a push bar (9) able to move within the guiding channel (8) and fastened to a second end of the pusher flag (12). This bar feeding device is further characterised in that the channel cover (4) comprises at least one displaceable member (14,14a) and an actuator (15) for displacing the displaceable member (14,14a). The invention also pertains to a process for using such a bar feeding device.

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.
