Abstract

The invention relates to an automatic control device for a bending machine for use in the production of loops of bar or wire material for concrete reinforcement. The device includes a preselector for preselecting the type of loop required and determines the sense of direction and amount of bending required in that loop-type. Additionally, a selector is provided for selecting the length of each side of the loop of the type selected by the loop-type preselector.
