  • Profiled wire screen for process flow and other applications
    Patent number: 9023456
    Abstract: A screen has a plurality of rods arranged longitudinally around a central axis. The rods have first and second edges (e.g., inner and outer edges). Each of the first edges defines a profile that varies in lateral distances from the central axis along a longitudinal length of the rod. For example, the first edges can have an undulating profile of crests and troughs. With the plurality of rods disposed around the central axis, the profile produces a varied surface on the screen when a plurality of wraps from one or more wires is disposed laterally around rods. These one or more wires attach to the first edges of the rods and form a plurality of gaps.
