Slub Type Patents (Class 57/209)
  • Patent number: 9677197
    Abstract: A spinning preparation machine for producing a roving from a fiber bundle includes a vortex chamber having an infeed opening for the fiber bundle and a yarn forming element extending at least partially into the vortex chamber. The spinning station includes spin nozzles, which lead into the vortex chamber in the region of a wall enclosing the vortex chamber and via which air is introduced into the vortex chamber in a specified direction of rotation in order to set the fiber bundle, which is fed in a transport direction, into rotation in the region of an inlet mouth of the yarn forming element. The yarn forming element includes a draw-off channel, which adjoins the inlet mouth and via which the yarn can be drawn out of the vortex chamber. The wall of the vortex chamber has a transition section, which adjoins the infeed opening, and has the shape of the circumferential surface of a truncated cone, and the diameter of which increases in the transport direction.

  • Patent number: 7721519
    Abstract: A method which improves the correspondence between the produced fancy yarn and the predetermined configuration of said fancy yarn. The fancy yarn is guided through a sensor device in a spinning device after it is formed and the diameter of the fancy yarn is continuously measured by the sensor device. The fancy configuration of the produced yarn is determined on the basis of the measured values of the diameter and is compared with the predetermined fancy configuration. The comparison is carried out until sufficient correspondence between the predetermined fancy configuration and the fancy configuration of the optimized, produced yarn is achieved.

  • Patent number: 6820405
    Abstract: The device serves to produce effect yarns on process machines through the deliberate production of short lumps in the yarn through short-duration yarn overfeed and includes a device (A) for lateral yarn deflection which comprises a motor-driveable, servo-controlled yarn guide (3) with an adjustable stroke. A movement of the yarn guide (3) in the one direction effects a slight underfeed and a movement in the other direction effects a pronounced overfeed of the yarn (F, F2). The yarn guide (3) is attached to a traverse-motion element (2), formed by a flexible member which is rigid in the stroke direction, preferably by a wire rope, a string or a belt, by which it is driven. The yarn guide (3) effects the storage of a yarn length, in the form of a loop, which corresponds to the desired overfeed. The device is used in false-twist and air texturing machines.

  • Patent number: 4926626
    Abstract: A method and apparatus for flamme fancy yarn manufacture for textile production of various number of effects along the length and in a given length of ready-made yarn, irrespective of the length of the fibres of the inlet product both from short staple and long staple material as the flamme fancy yarn is obtained by simultaneous feeding of two slivers with one and the same staple fibres length, as one of the slivers may not be subjected to a permanent force in the draft zone, it may be drawn normally without breaking to be used for the formation of a core thread. The apparatus for achieving the method has the advantage of an easy readjustable construction, and the ability to change the range of products without replacement of the performing elements.

  • Patent number: 4334401
    Abstract: A filament yarn of greater than 60 percent extensibility is combined with a carrier yarn. The combined yarn is false-twisted under tension in a unit employing rotary friction elements so that the filaments of the extensible yarn break intermittently while the carrier yarn remains intact to produce a spun-like textured yarn. The tension during false-twisting may be increased to a level at which the broken filaments snarl and form slubs in the yarn. The process may be carried out with no heat setting of the false-twist to form crimps. Suitable extensible yarns include undrawn and partially-orientated yarns, polyamide and polyester yarns, and suitable carrier yarns include fully-drawn filament yarns and spun yarns.
