Machine (10) for the formation of a metal mesh (11) obtained by attaching together a plurality of longitudinal metal wires (13) to a plurality of transverse metal wires (15). The machine (10) comprises a first feed assembly (12) to make the longitudinal wires (13) advance step-wise, a second feed assembly (14) to arrange one transverse wire (15) at a time in a first preparation position, a positioning apparatus to arrange the transverse wire (15) in a second attachment position, and a welding assembly (16) to attach the transverse wires (15) to the longitudinal wires (13). The positioning apparatus comprises a loading assembly (30), provided with a gripping and transfer device (31), in order to locate the transverse wire (15) in the second attachment position. The machine (10) also comprises thrust means (33) to take the transverse wire (15) from the first preparation position to a third intermediate pick-up position, near the second attachment position, wherein the transverse wire (15) is picked up by the gripping and transfer device (31). The thrust means (33) comprises a rotary element (52) provided with blade means (54) able to thrust the transverse wire (15) from the first preparation position to the third intermediate pick-up position. |
