Abstract

A screen panel is provided in which the usual relatively costly wear resisting elastomeric material which defines the screen apertures is partly constituted by a less costly plastics base, typically made of a structural plastics material such as poly propylene. The result is a replacement of costly elastomeric material in regions of a screen panel not normally subjected directly to wear by less costly structural plastics material. The material also provides a screen assembly embodying a method of attaching the individual screen panels to a screen supporting panel which is particularly appropriate to screen panels provided by the invention.
