Abstract: A filter screen is formed by a first sheet metal frame having one or more cutout sections or a plurality of perforations. A first layer of screening is placed on top of the frame but does not extend to the edges of the frame. An optional second layer of screening may be placed over the top of the first layer such that it extends beyond the perimeter of the first layer but not to the perimeter of the frame. The assembly is then fusion bonded together and rolled into a tubular configuration. Abutting edges of the frame are welded together to form a rigid filter screen.
