Abstract
Apparatus for bending steel bars to form concrete reinforcement elements, having a device (3, 4; 18) for feeding bars to a transfer device (8), by means of which in each case one group of bars can be inserted in two bending frames or stations, (2, 2'), each having members (11, 12) for bending the bars in transverse direction the transfer device having at least one pair of operation-controlled gripper tongs (10) which can be swivelled from a first position, in which they receive a plurality of bars from the bar feed device, and clamp the bars, into a second position, in which they insert the bars into the gap between the bending members.
