Disclosed is a separator comprising a bed comprising a plurality of walls, a screen supported in the bed, a housing disposed adjacent one of the walls, a bolt member connected to the screen and adapted for translational movement relative to the housing, a rotating member in threaded engagement with the bolt member for receiving torque, spring means for applying an axial force against the rotating member so that rotation of the rotating member in a first direction causes relative translational movement between the rotating member and the bolt member to apply a tension to the screen, and rotation of the rotating member in a second direction causes relative translational movement between the rotating member and the bolt member to release tension on the screen, and means for limiting the translational movement of one of the members in response to a predetermined tension of the screen. Also disclosed are a method and a device for tensioning the screen relative to one of the wall of the separator.
