Abstract
The mechanism is intended for making the reinforcement for concrete tubes. It holds the longitudinal steel bars (21) whilst laying the circumferential wires around them and welding them together at the cross-over points. A frame carrying a support disc is coaxial to the tube centre and has radially adjustable supports through which the bars can be axially inserted and held. An axially movable co-axial clamp disc (1-3) holds the other ends of the bars. These ends are clamped in radially extending slots between pairs of clamp jaws (5,6) which may be applied by actuators (19) arranged between sets of two adjacent pairs.
Welding machine for mfr. of telegraphy pole steel reinforcement - draws long bars through rotary frame which controls bar spacing and resistance welds bars (BR 9.5.78)
