Abstract

A sieving fabric (01) with a polyurethane edge containing eyelets (10) fastened to tensioning plates (04). These tensioning plates (04) are fixed using hinges to the chassis of the sieve (02). The air chamber (03) located in the profiled chassis (02) is pressurised and this tensions the fabric (01). Fitting and removing a sieving fabric (01) is very easy as long as the pressure in the air chamber (03) is lowered. The choice of the pressure will provide the desired tension. An outlet mat (07) permits the unsieved particles to be evacuated easily.<IMAGE>

   DESCRIPTION Système de tension pneumatique à chambre à air pour toile fine de tamisa2e bordée avec oeillets L'invention concerne un système de tension à chambre à air pour toile fine de tamisage bordée d'oeillets (fig. 1) (fig. 2) La toile tamisante (01) est renforcée sur son pourtour d'une double bande de polyuréthane (10) perforée par des oeillets et accrochée à plusieurs plaques de tension   (o4)   montées sur charnières. 



  La tension de cette toile se fait grâce au gonflement, par pression d'air, d'une chambre à air (03) qui agit sur les plaques de tension (04). 



  Pour permettre aux particules non tamisées de tomber aisément dans l'entonnoir de sortie (11) on place une bavette de protection (07) sur l'extrémité de la toile tamisante (01).

   DESCRIPTION The pneumatic tensioning system with air chamber for fine screen fabric bordered with eyelets The invention relates to a tensioning system with air chamber for fine screen fabric bordered with eyelets (fig. 1) (fig. 2) The fabric screen (01) is reinforced on its periphery with a double polyurethane strip (10) perforated with eyelets and attached to several tension plates (o4) mounted on hinges.



  The tension of this fabric is made by the inflation, by air pressure, of an air chamber (03) which acts on the tension plates (04).



  To allow unscreened particles to fall easily into the outlet funnel (11), place a protective flap (07) on the end of the screen cloth (01).

Claims (1)

REVENDICATIONS La toile tamisante (01) est posée sur le châssis de la tamiseuse et accrochée très aisément aux plaques de tension (04) étant donné qu'à ce moment les chambres à air (03) sont dégonflées. CLAIMS The sieve cloth (01) is placed on the sieve frame and very easily hooked to the tension plates (04) since at this time the air chambers (03) are deflated. Une fois que la toile (01) est accrochée sur son pourtour, on peut mettre la pression via un ensemble pneumatique composé de quatre entrées d'air (08) et faire gonfler les chambres à air (03). Once the fabric (01) is hooked on its periphery, one can put the pressure via a pneumatic assembly made up of four air inlets (08) and make inflate the air chambers (03). Le gonflement des chambres à air permet de faire pivoter les crochets de tension (04) vers l'extérieur et ainsi tendre la toile (01) à la tension voulue. The inflation of the air chambers makes it possible to pivot the tension hooks (04) outwards and thus stretch the fabric (01) to the desired tension. La tension sera réglable en fonction de la pression choisie suivant le type de toile placé sur la machine. The tension will be adjustable according to the pressure chosen according to the type of fabric placed on the machine. La façon de tendre la toile peut aussi être choisie comme par exemple tendre la toile sur la longueur et ensuite sur la largeur. The way of stretching the canvas can also be chosen such as for example stretching the canvas over the length and then across the width. On peut également choisir des pression différentes pour la longueur ou la largeur. You can also choose different pressures for length or width.
