Screen system
First Claim
1. A screen system suitable for use in a vibratory screen apparatus, said screen system comprising:
- a screen element consisting essentially of a mesh panel provided with first and second elongate support members extending along opposite end portions of said mesh panel; and
a support frame for said screen element, said support frame having spaced apart first and second elongate frame elements for engagement with said screen element support members in use of the screen system, and further elongate frame elements extending between said first and second frame elements for supporting said mesh panel of said screen element;
said support frame being provided with at least one mesh panel support provided with an elevating support surface, and formed and arranged so that elevation of said elevating support surface tensions said screen element across said support surface and between said screen element support members, said screen element support members and said first and second frame elements being formed and arranged for secure interengagement in use of the screen system with at least one of said screen element support members and the respective one of said first and second frame elements being formed and arranged so that when said screen element is tensioned by said mesh panel support with said support surface thereof elevated, in use of the screen system, said mesh panel is securely held under tension and said screen element support members driven into securely gripped interengagement with said first and second frame elements.

Abstract
A screen system 8 suitable for use in a vibratory screen apparatus 1, comprising: a screen element 11 consisting essentially of a mesh panel 19 provided with first and second elongate support members 22, 23 extending along opposite end portions 20, 21; and a support frame 12 therefor. The support frame 12 has spaced apart first and second elongate frame elements 13, 14 for engagement with said screen element support members 22, 23 and further elongate frame elements 17, 18 extending between the first and second frame elements 13, 14 for supporting the mesh panel 19. The support frame 12 is provided with at least one mesh panel support 27 provided with an elevating support surface, which tensions the screen element 11 across the support surface 27 and between the screen element support members 22, 23. The latter 22, 23 and the first and second frame elements 13, 14 are being formed and arranged for secure interengagement. At least one of the screen element support members 22, 23 and the respective one of the first and second frame elements 13, 14 is formed and arranged so that when the screen element 19 is tensioned by the mesh panel support 27 with the support surface thereof elevated, the mesh panel 19 is securely held under tension and the screen element support members 22, 23 are driven into securely gripped interengagement with the frame elements 13, 14.
