  • Patent number: 6047534
    Abstract: Regarding an independently driven type spindle in a spinning machine, when a yarn breakage is occurred in a spindle 10, a brake operating member 35 of the spindle 10 is moved toward a spindle shaft 13. During the movement of the brake operating member 35, control surfaces 49 of the brake operating member 35 cause the stop/restart switches 46 and 47 to be made OFF between the electric driving motor 20 and alternate current lines S and T, thereby causing the motor 20 to be rotated under its own momentum. Then, braking parts 34 of the brake operating member 35 is pressed to the outer peripheral surface of the spindle shaft 13, thereby executing a mechanical braking operation. After the withdrawal of an end of broken yarn, the brake operating member 35 is released, so that a force of the springs 41 causes the brake operating member 35 to be detached from the spindle shaft 13, thereby canceling the braking operation.

  • Patent number: 6047536
    Abstract: A textile machine for texturing textile yarns by false twisting, heating and cooling the false twisted yarns, has yarn feeding devices, a heating device with a heated surface, a cooling zone and a false twisting device. The feeding devices are operable to feed a yarn along a longitudinal yarn path in contact with the heated surface, through the cooling zone and the false twisting device. In such a machine, to provide that the surge speed is higher than would be the case with a conventional contact heater arrangement or guided non-contact heaters, to allow processing at these higher speeds without detriment to the yarn properties, and to minimize the temperature settings and hence the power consumption of the heater, the heated surface is substantially flat along the longitudinal yarn path, and the yarn path in the cooling zone extends in a direction different from that of the longitudinal yarn path.

  • Patent number: 6047537
    Abstract: In a method for producing a twisted yarn by an integrated spinning and twisting process, individual spun yarns are spun from loose fiber material in at least two spinning devices. The spun yarns are combined and guided in a first direction and subjected to a common first twisting to form a once twisted yarn. The once twisted yarn is then guided in a second direction opposite the first direction according to the two-for-one twisting principle, to form a yarn balloon in order to subject the once twisted yarn to a second twisting. The resulting yarn is then fed through a centering point to a winding device. The loose fiber material is fed into the annular chamber, that is coaxial to the yarn balloon and in which the yarn balloon freely rotates, and is guided substantially radially through the yarn balloon such that the yarn of the yarn balloon directly passes through the loose fiber material.

  • Patent number: 6041586
    Abstract: In a yarn false twist texturing process in which yarn is passed through heating and cooling zones to a false twist device, the yarn is passed in a helical path around a cylinder at opposed ends of which yarn guides are disposed to provide the helical path, preferably through the cooling zone. In order to raise the surge speed at which the process becomes unstable, at least one of the yarn guides is positionally adjustable relative to another guide and/or a third guide is located between the other two so as to increase the helix angle of the yarn path and the effective angle of wrap around a cylindrical cooling device on which the guides are mounted. The cooling cylinder may be a tube to which suction is applied to draw fumes from the yarn as it passes over a port in the tube and to draw ambient air into the tube to assist the cooling effect. The non-abrupt changes in direction of the yarn path allows the twist to run back through the cooling and heating zones.

  • Patent number: 6041585
    Abstract: To prevent yarn from being cut when an operating spinning machine stops, thereby preventing subsequent re-activation from being affected. In a spinning machine for manufacturing yarn by passing a fiber bundle that exits a draft apparatus 1 through a spinning nozzle 2 injecting a swirling air current and then through a twisting apparatus 3 that twists the fiber bundle in a direction reverse to that of the swirling air current, each spinning unit is driven independently, and the draft apparatus 1 can be decelerated or accelerated with the speed ratio of each pair of rollers being maintained. When the spinning is stopped or activated, the draft apparatus 1 and the twisting apparatus 3 simultaneously decelerate or accelerate so as to be simultaneously stopped or activated, and in response to this operation, air injection from the spinning nozzle 2 stops or starts.
