ABSTRACT:
A method for making cylindrical welded wire screens by continuously bending a wire into a helical wrap with juxtaposed equal wraps having their diameter substantially equal to the desired finished diameter of the screen whereby the radius of curvature applied to the wire is smaller than the radius of the wrap and the bending area is inside the outer circumference, supporting the wraps and progressively guiding them and bringing them into contact with supporting wires substantially parallel to the generatrix of the cylinder, and welding the wraps to the supporting wires at their contact points.
