Abstract

The machine comprises identical stations placed side by side to produce the complete frame in one setup. On each station bar for the transverse frame (ET) is fed to a stop and a longitudinal bar (EL) placed in a clamp (21). A hydraulic cylinder (19) strokes upwards and a head (14) forms the transversal bar over the longitudinal, the two being welded or tied together. The cylinder retracts, the clamp opens and the assembly fed to a stop (25, 28, 38). After clamping a longitudinal bar in place, the cylinder bends the transversal bar up, forming one side. The cycle is repeated to complete the frame.
