Polyurethane Vibratory Screen

A vibratory screen, comprising:

• a flexible molded polyurethane body having substantially parallel side edge portions at opposite ends of the body, a lower edge portion substantially perpendicular to the side edge portions, an upper edge portion substantially perpendicular to the side edge portions and opposite the lower edge portion, an upper surface, a lower surface, first and second members forming screening openings, the first members extending between the side edge portions and the second members extending between the lower edge portion and the upper edge portion, third and fourth members, the 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 at least one of the first and second members, and reinforcement rods molded integrally with the fourth members.

A vibratory screen, comprising:

• a flexible molded polyurethane body, screen openings in the body, first substantially parallel flexible members defining opposite sides of the screen openings, second substantially parallel flexible members defining opposite sides of the screen openings, the first members substantially perpendicular to the second members, third members substantially parallel and having multiple first members therebetween, fourth members substantially parallel and having multiple second members therebetween, reinforcement rods molded integrally with the fourth members, side edge portions substantially parallel at opposite sides of the body between which the third members and reinforcement members therein extend, first and second end portions substantially parallel at opposite ends of the body between which the fourth members and reinforcement members therein extend, the side portions substantially perpendicular to the end portions.
