Abstract

In addition to a link-type preselection device (35-38), the automatic control system comprises a limb-length selection device (32). By preselection of the link type, a basic programme assigned to each link type and comprising the direction and magnitude of the successive bending angles for each link is defined and the limb-length selection device permits free selection of the lengths of the successive limbs of the links. It is thereby possible to preset all the bending operations required for the production of a link, as regards the length of the individual limbs of the links, the magnitude of the bending angle and the separation of the finished link from the bar or rod material. The categorisation of the most frequently required concrete reinforcement links into just a few link types with a particular sequence of bending locations makes it possible to produce these more frequently required link types more efficiently. <IMAGE>
