Abstract: Machine for the formation of a metal mesh obtained by attaching together a plurality of longitudinal metal wires to a plurality of transverse metal wires. The machine includes a first feed assembly to make the longitudinal wires advance step-wise, a second feed assembly to arrange one transverse wire at a time in a first preparation position, a positioning apparatus to arrange the transverse wire in a second attachment position, and a welding assembly to attach the transverse wires to the longitudinal wires. The positioning apparatus includes a loading assembly, provided with a gripping and transfer device, to locate the transverse wire in the second attachment position. The machine also includes a thrusting device to take the transverse wire from the first preparation position to a third intermediate pick-up position, near the second attachment position, wherein the transverse wire is picked up by the gripping and transfer device.

Abstract: Device and method for the automatic formation of packs of panels of electro-welded mesh. The device is arranged downstream of a production machine provided with a work plane. The device is provided with an expulsion element which arranges the panels emerging from the machine onto an accumulation plane located as an extension to the work plane of the machine, a turnover device which turns over every other panel with respect to the position in which it exits the machine, and a discharge device to discharge the panels. The device also comprises a switching device arranged downstream of the expulsion device in order to direct alternately, and substantially continuously, at least one panel either directly towards the accumulation plane or towards the turnover device.
