1. A welding machine for wire meshes which consist of longitudinal and transverse wires and are welded at their points of intersection, more particularly for concrete reinforcing purposes, comprising a number of welding units (8-18) which are disposed one beside the other and can be individually moved on rails by a drive and each comprise a longitudinal wire guide (19) and have upper and lower welding electrodes (21, 20) adjusted in relation to one another and with which a welding transformer (22) is associated, the machine also having a driven longitudinal wire supply means comprising upper and lower clamping rollers (41, 42) which can be adjusted in relation one another, characterized in that mounted to rotate freely on each welding unit (8-18) on one side of the longitudinal wires to be supplied is a clamping roller (42) whose pheriphery is formed wire a guide groove ; each of the clamping rollers (42) has an adjusting member (44), and associated with the clamping rollers (42) on the other side of the longitudinal wires to be supplied and mounted in the machine frame is a driven clamping roller (41) extending over the whole adjusting width of the welding unit (8-18) and having no guide grooves in its generated surface. |
