  • Patent number: 11078602
    Abstract: A yarn head rotor 1 for a cabling machine, having several deflection rollers 2 for evening the yarn tension of two yams being twisted, each deflection roller being rotatably mounted on a pivot axis 5 at right angles to the rotor axis of the yarn head rotor 1 and guided across the two yarns. The deflection roller 2 is mounted in the yarn head rotor 1 by bearings 6 at both ends of the deflection roller 2, wherein the two ball bearings 6 are each enclosed by a housing 7 of the yarn head rotor 1, which is closed with a cover 8, and yarn guiding eyelets 9, guiding the inner and outer yarns 17, are arranged upstream of the deflection roller 2 in such a way that they supply both yarns of the deflection roller between the two ball bearings 6 to the yarn head rotor 1.

  • Patent number: 10793978
    Abstract: A workstation (1) of a two-for-one twisting or cabling machine which comprises a rotatably mounted spindle (2) and a balloon-yarn-guide-eye (9) height-adjustable by means of a drive (18, 29) coupled to a control device (20) which controls the drive (18, 29) in such a manner that it displaces the balloon-yarn-guide-eye (9) between operating positions (AP1, AP2) dependent upon production parameters and a resting position (RS) advantageous in the case of production interruptions and transient operating phases associated with the latter. A device (21, 23, 24, 25) is present for detecting a measured value (i), which is made available to the control device (20) and which causes the control of the drive (18, 29) to change the position of the balloon-yarn-guide-eye (9).

  • Patent number: 10196761
    Abstract: A method for operating a spindle (2) of a two-for-one twisting or cabling machine which has an adjustable balloon-yarn-guide-eye (9), wherein for the operation of the spindle (2) under production conditions, the balloon-yarn-guide-eye (9) is adjusted, on the basis of a measured value (i) correlating with the energy consumption of the spindle drive (3), to a first operating position (AP1), in which a position-dependent minimum of the energy consumption of the spindle drive (3) is reached.
