Abstract
A woven wire screen is held tightly on a circular tension ring mount and attached directly thereto by welding. A basic Z-shape for the tension ring is modified by a vertical partial drop from the inner part of the tension ring in order to prevent jamming of anti-blinding devices. The overall structure provides the necessary stiffness and is devoid of crevices and the like, which would not be suitable in a sanitary environment.
