Abstract

For use in the fabrication of steel bar reinforcement cages for concrete members, the automatic machine ties two intersecting bars together. In particular stirrups (e) are tied to longitudinal bars (A), using hydraulic rams with rack and pinion and pincer mechanisms. First, cranked levers (1, 2) on a common axle (3) pivot to the size of the bar. The rams (V2-V3) controlling their movement also feed a length of wire through rack (6) and pinion (7) driven friction rollers (8, 9). Guide blocks feed the wire around the bar (A), the wire end then being grasped by a pincer mechanism on a pivoting 'U' shaped handling arm. The arm swings to and fro and moves laterally to pass the wire round the stirrup. It then passes the wire to a second revolving pincer mechanism which twists the wire ends together.
