MULTIELECTRODE MACHINE FOR WELDING REINFORCING FABRICS Russian patent published in 1994 - IPC

FIELD: manufacture of fabrics for reinforced concrete articles. SUBSTANCE: device has welding mechanism with electrodes and fabric step motion mechanism, both mounted on bed frame. Fabric step motion mechanism is made in form of beam installed on bed frame for reciprocating square to axis of feeding of cross bars. Hinge-mounted on beam at one side are spring-loaded rods with catches for cross bars. At other side pushers are hinge-mounted on beam on common axle for turning around their axes. Turning of pushers is limited by stop secured on beam. On free end of pusher wedge-type stop is installed which has through slot in its lower plane. By means of this slot pushers embrace longitudinal bar from both sides and, thrusting against cross bar, shift fabric by one step. EFFECT: enlarged operating capabilities. 4 dwg
