A digital signal processor system is provided which detects defect in tubular knit fabric. The signal processor system is attached to a circular knitting machine or the like and utilizes a fiber optic scanning head for obtaining light reflectance data from the material. Fiber optic material is utilized to project light against the fabric web and another fiber optic bundle is utilized to read reflected light. A opto-sensor pixel array is utilized to provide voltage data to a digital signal processor which then analyzes the data to determine the existence of end out, holes, light or heavy yarn and needle run conditions.

An apparatus for washing cylindrical filters has a tiltedly-mounted main housing in which is provided a plurality of rotatable shafts each mounting thereabout one cylindrical filter for rotation therewith. The tilted mounting causes the wash water, after cleaning the filters, to fall by gravity therebelow, and exit from the apparatus at a lower exit corner thereof. From the exit corner of the apparatus, the effluent wash water passes through a cloth filter provided on a portable container before the effluent wash water is carried away by a drain grate formed in the floor. The cloth filter removes the sold waste from the effluent wash water, so that the potentially hazardous waste material may be disposed of in a suitable dump site. A plurality of high-pressure, water-spray nozzle heads are mounted for reciprocal translation above the shafts for directing the high-intensity water spray to the cylindrical filter.
