Abstract
Molded polyurethane screens having reinforcement therein are known in the art. However, in the past the dividing strips between the openings were relatively large, thereby causing the open area of the screen to be an undesirably low percentage of its surface, thereby in turn causing the screen to be relatively inefficient. The present invention provides improved screens with relatively high percentage open screening areas and high efficiencies. In one embodiment, the present invention provides amolded polyurethane vibratory screen including a body having opposite side edge portions, upper and lower edge portions, an upper surface and a lower surface, first members extending between the side edge portions and the second members extending between the lower edge portion and the upper edge portion, third members substantially parallel and extending transversely between the side edge portions and having multiple first members therebetween, the fourth members substantially parallel and extending transversely between the lower edge portion and the upper edge portion and having multiple second members therebetween, reinforcement members molded integrally with the third and fourth members.
