Abstract
A disk screen or like shaft structure is disclosed in which screen disks, surround disks, and spacers are connected together in modular relation. The surround disks have metallic flanges which shield the plastic spacers which are located on either side of the surround disks between the screen dists. The spacers are formed of resilient plastic to allow the disks to deflect from their radial plane and the flanges of the surround disks are sufficiently smaller than the spacers to avoid contact with the screen disks in their deflectred positions. The assembly is placed under a predertermined endwise compression and the module if mounted on a rectangular shaft which is suitably supported for rotation. The assembly is particularly suited for screening a wood chips in the paper making industry where exposed plastic parts is undersirable.
