Abstract
A process for producing metal wire screens having extremely narrow slot widths. The process comprises compressing along the longitudinal axes of the supporting wires a wire screen having parallel narrowly spaced screening wires supported by parallel supporting wires and wherein the average spacing of the screening wires is larger than desired. The compression effects plastic deformation of the supporting wires whereby the desired average slot width is formed.
Claims28
A wire screen having substantially parallel screening wires separated by slots of a desired average slot width less than 25 microns, said screen produced by compressing, along the longitudinal axes of the supporting wires, a wire screen comprising substantially parallel screen wires supported by supporting wires and wherein the screening wires are separated by slots having an average slot width greater than desired, the compression effecting plastic deformation of the supporting wires to narrow the slot width of the screening wires to thereby form the said wire screen having the desired average slot width.
A process for producing wire screens having substantially parallel screening wires separated by slots of a desired average slot width less than 25 microns, the process comprising compressing, along the longitudinal axes of the supporting wires, a wire screen comprising substantially parallel screening wires supported by supporting wires and wherein the screening wires are separated by slots having an average slot width greater than desired, the compression effecting plastic deformation of the supporting wires to narrow the slot width of the screening wires to thereby form a wire screen having the desired average slot width.
A process for producing wire screens of the type referred to having a desired average slot width which is less than 25 .mu.m which comprises compressing along the longitudinal axes of the supporting wires a wire screen of the type referred to having a larger than desired average slot width whereby plastic deformation of the supporting wires is effected and a wire screen having the desired average slot width is thereby formed.
