  • Patent number: 5003793
    Abstract: The invention relates to a card wheel for a knitting machine for manufacturing knit goods with combed-in fibers. The card wheel consists of a wheel body with a cylindrical circumferential surface and a card clothing situated and fixed on the latter, which contains a cloth band of appropriate width lying on the circumferential surface and hooks incorporated into the band. In accordance with the invention the cloth band has at least one lateral end a holding section free of hooks which runs along the entire circumferential surface. To fix the card clothing in place, a clamping means acting on the holding section is provided in accordance with the invention, which clamps the holding section with a pressure per unit area on the circumferential surface which prevents the cloth band from slipping.

  • Patent number: 4978747
    Abstract: Colorants are obtained by reacting a dyestuff which is free from ionic groups and has.gtoreq.2 NH.sub.2 groups which are preferably arranged in such a manner that they do not participate in the resonance of the chromophore with such an amount of a (cyclo)aliphatic diisocyante so as to form an adduct that still contains at least two free NCO groups, and subsequently reacting this adduct with a (cyclo)aliphatic diamine, to form an adduct suitable for dyeing and pigmenting macromolecular substances, in particular for coloring PUR-based paints, coatings and laminates.

  • Patent number: 4765156
    Abstract: The invention relates to a circular knitting machine for the production of knit goods with combed-in fibers, having a rotatable, needle-bearing needle cylinder and a card which has a means for feeding the fibers, a comb-in zone through which the needles pass for the purpose of contactlessly receiving the fibers, and a teasing cylinder rotating at high speed which takes the fibers from the feed means and yields them to the comb-in zone. To prevent thin areas or thick areas from being produced in the finished goods on account of the contactless fiber loading, the circular knitting machine has a protective device (60) which becomes active in the still state of the needle cylinder for the purpose of retaining the already combed-in fiber tufts (57) in the needles (3) which are in the comb-in zone in the still state of the needle cylinder.

  • Patent number: 4760716
    Abstract: The invention concerns a process and a circular knitting machine for the production of knit goods with combed-in fibers, in which an amount of fibers synchronous with the needle cylinder rotatory speed is fed to a teasing cylinder rotating at high speed, transferred by the latter to the comb-in zone, and taken from the needles in the comb-in zone without contacting the teasing cylinder. To prevent the development of areas overfilled with fibers or short of fibers in the finished knit goods on account of the contact-less fiber feed, during or before abrupt reductions or increases in the rotatory speed of the needle cylinder, at least temporarily smaller or larger amounts of fibers are fed to the comb-in zone than corresponds to the synchronous amount of fibers.

  • Patent number: 4750935
    Abstract: Printing inks are described which utilize a unique class of coloring agents which are the reaction products of free NCO group bearing resins and dyestuffs bearing reactive hydrogens. A novel class of such adducts which contain monocarboxylic acid residues are also described. These printing inks, which may also contain traditional pigments, find particular utility in letterpress or offset printing.

  • Patent number: 4563884
    Abstract: A circular knitting machine for the production of high-pile fabrics having combed-in fibres is disclosed herein. The knitting machine has a needle cylinder carrying knitting tools, at least one carding means for combing fibres into the knitting tools, an exhaust hood disposed above the needle cylinder and intended for the removal of loose fibres and at least one component disposed within and/or outside of the exhaust hood and fastenable thereto by means of at least one strut, to substantially eliminate the danger of any accumulation of loose fibres on the strut. The strut has an airfoil configuration.

  • Patent number: 4546622
    Abstract: A circular knitting machine for the production of knit goods with combed-in fibers, has a rotating needle cylinder in which needles having hooks for receiving fibers are mounted, at least one carding device having a feed apparatus for feeding a fiber strand, a separating apparatus for separating the fiber strand into a stream of individual fibers, and a combing-in zone through which the needles pass, and wherein the fibers are carried within the fiber stream for the purpose of contactlessly combing-in the fibers into the hooks of the needles. Guides are provided ahead of the combing-in zone for the purpose of dividing the fiber stream into partial fiber streams, thus considerably reducing or varying the percentage of fibers which are bound across several neighboring loops by several neighboring needles.
