ABSTRACT:
A multi-spot resistance-welding machine for manufacturing welded grids consisting of a group of longitudinal wires and crosswires crossing the longitudinal wires at right-angles, to enable grids to be manufactured in which the length of at least some of the crosswires is smaller than the width of the grid and in which the relative position of these shorter crosswires can be selected with respect to the group of longitudinal wires, is equipped with two crosswire feed devices (16, 40) of which at least one, but preferably both, can be displaced and fixed in an allocated guide (15, 17; 51, 52) transversely to the feed path of the group (70) of longitudinal wires and relative to a delivery device (60) transferring the crosswires from the feed devices into the welding area.
