Abstract

I en vibrasjons-silinnretning består silenheten (10) av et ark av fleksibelt dukmateriale (10A) med ribbeelementer (14) av en hard gummi eller liknende materiale som er støpt på innbyrdes parallelle, langsgående side-kantpartier. Silenheten (10) mon- teres ved å innføre ribbeelementene (14) i slissete rørholdere (13) hvorav en er forankret til et side- bæreelement (12) i silinnretningen og hvorav den andre er legemlig forskyvbar for å stramme dukmate- rialet (10A) ved hjelp av pneumatiske aktuatorer (18) som er forbundet med en enkelt trykkilde. Aktuatorene (18) trekker den forskyvbare holder (13) til et fast sted mot det motsatte side-bære- element (11) og som er fastlagt med referanse til en forutbestemt breddedimensjon hos silenheten (10), slik at dukmaterialet (10A) blir jevnt stram- met av aktuatorene (18). Utskifting av silenheten (10) kan således hurtig utføres med mindre fare for dukvridning på grunn av ujevn stramming. Slutt- stramming utføres ved hjelp av forskyvbare bæresta- ver (20) som på kjent måte strekker seg i lengde- retningen mellom side-bæreelementene (11, 12).In a vibration screen device, the screen unit (10) consists of a sheet of flexible cloth material (10A) with rib elements (14) of a hard rubber or similar material cast on mutually parallel longitudinal side edge portions. The screen unit (10) is mounted by inserting the rib elements (14) into slotted tube holders (13), one of which is anchored to a side support element (12) in the screen device and the other of which is physically displaceable to tighten the cloth material (10A). by means of pneumatic actuators (18) connected to a single pressure source. The actuators (18) pull the slidable holder (13) to a fixed location against the opposite side support element (11) and which are fixed with reference to a predetermined width dimension of the screen unit (10), so that the fabric material (10A) is even tightened by actuators (18). Thus, replacement of the screen assembly (10) can be performed quickly with less risk of fabric twist due to uneven tension. Final tensioning is carried out by means of displaceable support rods (20) which in a known manner extend in the longitudinal direction between the side support elements (11, 12).
