Abstract: A device for feeding transverse wires above and below a production line for mesh mats which consist of welded transverse and longitudinal wires, said device comprising an upper transverse wire feeder, which has a guide channel and which is arranged in a first position, in which transverse wires are fed along the guide channel of the production line, and comprising a lower transverse wire feeder, by means of which transverse wires can be conveyed from below to the production line, wherein a lower transverse wire store is provided, from which transverse wires can be removed by the lower transverse wire feeder, and wherein the upper transverse wire feeder is designed as a transverse wire switch, which can be pivoted at least into a second position, wherein the lower transverse wire store can be loaded with transverse wired by the transverse wire switch in the second position.

Abstract: A grid welding machine operating continuously based on the electrical resistance principle having a stationary longitudinal frame, whereon a horizontal group of parallel longitudinal wires can continuously be moved in the production direction by means of a feeding device, and having a pulling-off device, by means of which the cross wires can be pulled off a coil or rings and fed transversely to the group of longitudinal wires in a transfer device extending transversely, which transfer device can pick up multiple cross wires and convey them one after the other towards the longitudinal wires and bring them into contact with said longitudinal wires in the correct orientation according to the scaling of the cross wires and drop them there, and having electrodes and counter electrodes the weld surfaces of which can be pressed against each other with the points of intersection formed between the longitudinal wires and the cross wires therebetween.
