The present invention provides a screen system (8) suitable for use in a vibratory screen apparatus (1), and comprising: a screen element (11) and a support frame (12) therefor, as well novel screen elements (11) and mesh panels (19) therefor, and the use thereof. The screen element (11) consists essentially of a mesh panel (19) provided with first and second elongate support members (22, 23) extending along opposite end portions of the mesh panel (19). The support frame (12) has spaced apart first and second elongate frame elements (13, 14) for engagement with the screen element support members (22, 23) and further elongate frame elements (17, 18) extending there between for supporting the mesh panel (19). The screen element support members (22, 23) and said first and second frame elements (13, 14) are 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 clamped together, the mesh panel (19) is securely held under tension against said further frame elements (17, 18).

L'invention concerne un système écran (8) destiné à être utilisé dans un appareil à écran à vibration (1) et comprenant un élément écran (11) et un cadre de support (12), ainsi que de nouveaux éléments écran (11) et des panneaux en treillis (19), ainsi que son utilisation. L'élément écran (11) est essentiellement constitué d'un panneau en treillis (19) doté de premier et second éléments (22, 23) de support allongés s'étendant le long de parties terminales opposées du panneau en treillis (19). Le cadre de support (12) comporte des éléments (13, 14) de cadre allongés écartés l'un de l'autre et destinés à s'encliqueter avec les éléments de support d'élément écran (22, 23), ainsi que des éléments de cadre allongés (17, 18) s'étendant entre eux afin de supporter le panneau en treillis (19). Les éléments de support d'élément écran (22, 23) et lesdits premier et second éléments de cadre (13, 14) sont formés et disposés de manière à être fixés de façon sûre lors de l'utilisation du système écran, au moins un des éléments de support d'élément écran et un des éléments de cadre étant formés et disposés de manière que, une fois encastrés ensemble, le panneau en treillis (19) soit maintenu fermement sous tension et plaqué contre les éléments de cadre (17, 18).
