Abstract
A tubular filter element with a rigid, pervious core on which is wound roving in a criss-cross or diamond pattern to provide a variation in density of the wound roving from the interior portion adjacent the core to the outer surface. The change in density is achieved by varying the number of strands of a multi-strand roving during the winding process. In a preferred embodiment, the roving adjacent the core will be composed of three strands, while the roving of the outer portion will have only one strand.
