PURPOSE:To automate the knitting operation of vertical reinforcements and horizontal reinforcements and to improve accuracy by superposing the horizontal reinforcements on a suitable number of the vertical reinforcements which are let off intermittently, welding and fixing the reinforcements, bending the assembly by each prescribed length to form a knitted reinforcement and cutting and separating such reinforcement. CONSTITUTION:Horizontal reinforcements 10 are inserted laterally to respective vertical reinforcements 9 which are intermittently let off from a vertical reinforcement coil 24. The intersected points with the reinforcements 9 are welded and joined by the 1st spot welders 40. A primary reinforcement assembly is formed by repeating such welding stage and when the assembly is formed long and contacts with the stopper plate 65 of a positioning device 7, a bender 6 operates to bend the top ends of the respective reinforcements 9. The reinforcement welding stage is restarted upon completion of the end bending. The bent ends contact with the stopper plate 65 in the 2nd position and are again bent. A square shaped quaternary reinforcement assembly 89 is formed by repeating such stage. The reinforcements 9 are cut in the stage of forming a tertiary reinforcement assembly 89 and are joined after formation of the quaternary assembly 89, by which a square cage-shaped knitted reinforcement 90 having four planes 90a- is obtd. |
