Abstract

By a method for bending elements of bar material, e.g. rods for reinforcing concrete, and which is peculiar in that a clamping means (13, 14; 13, 15) within the area of a bending core (11) is brought to clamp the bar material during the bending operation, preferably in immediate vicinity of the centre of a bending disc (12), there is achieved a minimum of waste material after the last bending operation to which a rod is subjected.
