Abstract: Metallic clothing having metallic wire teeth bent at a double angle. The lower portion of each tooth is angled by an first angle with respect to vertical, and the upper portion is angled at a second angle with respect to vertical. The upper portion terminates at the tip, or point, of the tooth. This double-angle tooth profile is angled in the direction opposite to the general direction of travel of fibers being carded. The upper side portion of each tooth is tapered inwardly to the tip, and the rear edge of the upper end of each tooth may be provided with a forward curvature towards the point of the tooth. Alternate embodiments include single angled teeth and a double-angled teeth, each having a base portion substantially the same height as the teeth and teeth having serrated side portions.

Abstract: A textile fiber recycling machine for reprocessing hard thread waste, woven and non-woven fabrics, carpets, rugs, and the like. Material to be recycled is fed in pieces, or in roll form, into the machine. The machine includes a plurality of wire wound rolls positioned adjacent to one another and operating at successively higher rotational speeds from the inlet side to the outlet side of the machine. Closely spaced adjacent the rollers are carding segments. The rollers downstream of the entry roller include pairs of carding segments, with the leading carding segment being wire clothed, and the trailing carding segment being covered with a granular covering, such as sandpaper. The machine outputs open, usable fibers which can be used in subsequent conventional textile processes. A method of attaching sandpaper to a carding segment is also disclosed.

Abstract: An air doffing system for a fiber-processing machine which includes an air plenum associated with a carding roll. A doffing blade initiates lifting of fibers from a carding roll, and a laminar airflow pulls the fibers through the plenum. The airflow is pulled through a perforated roll on the opposite end of the plenum. The perforated roll operates in connection with a smooth roll to form a roller pair which work the fibers collected on the perforated into a web. The web is then formed into a sliver by a trumpet and a calendar roll pair.

Abstract: A ventilated carding cylinder for allowing heat generated in the carding cylinder during operation to be dissipated. The carding cylinder includes an internal, longitudinally extending, air flow passage and impeller means provided therein for moving air through the air flow passage during operation of the carding cylinder. This movement of air aids in dissipating heat generated by the carding cylinder during the fiber carding process. Reduction of heat in the carding cylinder can minimize the risk of fire occurring in the fibers and also thermal growth of the cylinder during operation.

Abstract: Method and apparatus for the intermittent cleaning of carding flats by the use of pressurized air. A carriage having a plurality of nozzles is oscillated intermittently back and forth on a track adjacent to flats revolving about a carding cylinder of a carding machine. Pressurized air delivered from the nozzles on the flats blow trash and debris from the clothing of the flats downwardly into a vacuum plenum for disposal. A proximity sensor is provided for sensing a flat to initiate the cleaning cycle, wherein the carriage and nozzles are activated for cleaning a particular carding flat. After the cleaning cycle, delivery of pressurized air to the nozzles is ceased and is again activated upon the next predetermined cleaning of a carding flat.

Abstract: A method of removing oil from a surface contaminated with oil comprises spreading elongated mat (A) of nonwoven cotton fiber on the surface of the oil to absorb the oil. The mat is prepared by forming cotton fibers into at least a first nonwoven fiber web (30) and a second nonwoven fiber web (32). A composite is formed by arranging the first and second fiber webs together with a scrim (34) intermediate the first and second fiber webs. The composite is delivered to a needle punch machine (54) and the first and second fiber webs are needle punched into the scrim. The mat is formed in a continuous length greater than its width. The cotton waste fibers are short and are needle punched and compacted into the scrim. Compacted interlocked mat (A) has sufficient strength to facilitate feeding of the mat longitudinally onto the oil (14) and surface, and pulling longitudinally from the surface after absorbing oil through an oil removal device (24) from said mat.
