Abstract
Molded elastomeric framing member has internal horizontal and vertical slots which are adapted to frictionally engage several of the longitudinal profile surface wires and portions of the transverse support bar members along a side edge of a flat deck screen panel. Parallel top and bottom portions of the framing member are adapted to be engaged by a support surface of a vibrating screen apparatus and a clamping apparatus carried by said screen apparatus. The framing member prevents metal-to-metal contact between the screen panel and vibrating apparatus, thus reducing the noise level of the apparatus. It also helps protect persons handling the panel from possible injury by rough edges and eliminates the expense and labor associated with the welding of side panels to the ends of the support bars. To prevent the screen panel from becoming electrically isolated from the vibrating screen apparatus, the elastomeric framing member can be made electrically conductive.
