Title: Segmented screen body

Abstract: A segmented screen body or bottom for classification, screening and washing of fragmented hard stocks employs a multiplicity of segmented elements constructed of elastomer or rubber material which, when abutted and supported in predetermined relations, define sieve apertures of a predetermined size and extending, if desired, in staggered longitudinal rows. The structure further requires a multiplicity of parallel transverse metal wires or equivalent elements which are embedded and extend through appropriate apertured portions of the elastic components. In the preferred form the essential elements include T-shaped and L-shaped elements, all of which may be obtained from identical integral moldings of T-shape and many of which are cut along transverse lines at the T-top to provide from the same moldings complementary L-shaped elements.
