Abstract
An apparatus and method for continuously washing and modifying a carpet pile to remove loose fibers and equalize the tension and spacing of the pile yarns to eliminate optical banding in dyed carpets. The apparatus comprises a processing tank through which the carpet web passes and which contains manipulating rollers that are provided with fins to brush against the carpet pile. Adjustable rollers push the carpet into contact with the manipulating rollers which can be rotated so as to brush the pile in opposing directions. The method involves passing the carpet through the tank in a U-shaped path such that the pile is brushed one way on the inward leg and the opposite way on the outward leg. At the bottom of the U, tension is applied against the back of the carpet to push the pile outward and aid in separation of the fibers.
