Abstract
A screen holder mechanism tensions a rotary screen in the axial direction thereof. Novel tensioning and retaining means are positioned between a screen holder and each end of the screen to position the screen at a predetermined vertical position. The tensioning and retaining means provides that the resultant of the axial tension applied to the screen coincides with the longitudinal axis of the screen, thereby avoiding dynamic stress on the screen.
