  • Patent number: 6059207
    Abstract: The present invention provides an inexpensive process which can be placed in the carpet mill to add value to carpet selvage waste by segregating the various materials used to manufacture the selvage waste. The process for segregating at least one component of a carpet selvage waste comprises the steps of:a. providing carpet selvage waste from carpet manufacturing comprised of tufts comprised of face fiber material, primary backing, an adhesive and optionally a secondary backing,b. identifying face fiber type used in the tufts in the carpet selvage,c. removing the face fiber from the carpet selvage such that the face fiber is essentially free of the primary backing and residual adhesive andd. segregating the removed face fiber from the remainder of the carpet selvage in a mechanical system which segregates fiber by fiber type to obtain a relatively pure stream of the face fiber.All removed, segregated components may be recycled and/or reused.
