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).
