ABSTRACT:
The machine for producing metal reinforcements in particular for reinforced concrete comprises a plurality of longitudinal members and at least one welded connecting member in the form of a strap in the shape of a closed or open frame. The machine comprises a strap carrier having open grooves for the passage of the longitudinal members which under the thrust exerted by a thrust device, come into direct contact with the straps waiting on the strap carrier so as to drive them one-by-one merely under the effect of friction to welding stations. The latter are adjustable in position and are in facing relation to zones of intersection between the longitudinal members and the straps. A selecting device and a stop device distribute the straps individually from the strap carrier to the welding stations. The strap carrier is fed with a series of straps required for a given reinforcement length by a withdrawable feeder and the welded reinforcements are discharged by a movable seizing device.
