US 4,380,494 A · Vibrating screen with self-supporting screen cloth

Abstract

A plurality of truss-like supports are secured, as by welding, and in spaced relationship, to the underside of a screen cloth. The supported screen cloth is then removably secured in position in a vibrating frame to form therewith a vibrating screen. Each truss-like support includes a support rod formed of wire rod of predetermined diameter disposed with a major portion thereof spaced from and substantially parallel to the plane of the screen cloth, and with end portions thereof merging into the plane of the end pieces of selected wire rods forming the screen cloth and being welded thereto. A spacer wire, formed from wire rod of a diameter less than that of the support rod and to an approximate sinusoidal configuration, is disposed so that the upper tips, formed by the sine configuration, are welded to the bottom surface of the screen cloth and so that the lower such tips are welded to the upper surface of the support rod.

A screen panel for use in a vibrating screen;

comprising:
(a) screen cloth means formed from a plurality of rod-like members woven together to form a screen with openings of predetermined size and configuration;
and
(b) truss-like support means arranged beneath and secured to the underside of said screen cloth means;
(c) said truss-like support means including at least one truss-like support assembly disposed beneath and secured to said under surface of said screen cloth means;
said truss-like support assembly;
