Abstract
A method and apparatus for producing wire grid mats from longitudinal wires and transverse wires (L, Q) crossing one another at right angles and welded at the crossing points, in which the longitudinal wires are advanced incrementally and the transverse wires are moved transversely to the motion of the longitudinal wires into a welding line and are welded to the longitudinal wires, and at least one of the transverse wires, after being delivered to the welding line, is clamped with a predetermined adjustable magnitude, and that before being welded to the longitudinal wires at least one end of this transverse wire is rotated by a predetermined adjustable angle about its longitudinal axis, whereupon the transverse wire is welded to the longitudinal wires.
