Multipoint mesh welding machine

A multipoint mesh welding machine for use in manufacturing a mesh, comprising, in combination:

• a row of welding electrode holders on one side of said working plane;
• at least two busbars associated with each of said electrode holders, said mesh defining a working plane and including a direction of advancement, said busbars extending across said machine transverse of said direction of advancement;
• an adjustable switching means associated with each of said electrode holders and operable for electrically connecting its associated electrode holder to a selected one of its associate busbars;
• each of said electrode holders and its associated busbars including contact surfaces substantially parallel and facing one another;
• each of said switching means comprising a conductive body disposed between its associated welding electrode holder and busbars and being operable to be slid transversely to the associated busbars and including contact surface means for cooperating selectively with the contact surfaces on the associated busbars and electrode holder;
• said row of electrode holders being associated with four of said busbars and said sliding body having a length equal to the sum of the widths of said contact surfaces of three of said busbars, opposite faces of said sliding body being partially covered with areas of insulation arranged offset with respect to one another in such a way that two conductive areas each equal in width to that of said contact surface of one of said busbars are exposed one at one end of one of said opposite faces and the other at the opposite end of the opposite one of said opposite faces.
