    摘要: A yarn break detecting device for a spinning machine includes detectors, a feed section and a control section. The detectors each include a pair of electrodes having substantially the same area and adapted to electrically induce a potential depending on static electricity charged on a yarn, a differential amplifier, a waveform shaper and an indicator lamp. The induced potential is then amplified and rectified to turn on the indicator lamp and concurrently fed to a microprocessor in the control section for operation processing, resulting in positions at which yarn break occurs and the number of yarn breaks being indicated.

    摘要: An electronic circuitry for evaluating electrical sensing signals furnished by a sensing device responsive to ballooning motion of a yarn in a textile machine and delivering a series of high frequency pulses having a repetition rate corresponding to the low frequency of the ballooning motion, comprises a series arrangement of an A.C.-amplifier, a rectifier, a low-pass filter having an upper cut-off frequency smaller than said high frequency but greater than the low frequency of the ballooning motion, and a frequency discriminator made up of a high-pass filter and integrator, and a final stage to either indicate improper yarn ballooning or disable the machine operation.

    摘要: An apparatus for detecting a yarn movement comprises a yarn guide unit for the sliding guidance of a moving yarn, and a converter cooperating with the yarn guide unit for generating an electric signal. With the aim of improving the signal-noise ratio of an apparatus of this type, there is provided a member mounted for movement relative to the yarn guide unit and disposed such that the yarn is guided between the member and the yarn guide unit in simultaneous contact with the member and the yarn guide unit, the member being subjected to a biasing action relative to the yarn guide unit.

    摘要: A ring spinning machine for spinning yarns comprised of finite length fibers has a plurality of spinning locations for combining two untwisted textile strands into a yarn to which a twist is imparted prior to winding up of the yarn. A sensor is associated at each spinning location which reacts to a break of one of the two fiber strands and causes an interruption of the spinning of the yarn. The sensor is designed to sense a characteristic of the yarn which changes in a manner recognizable by the sensor when the yarn is only being spun from one of the two fiber strands and an interrupter is provided which acts in response to the signal from the sensor to interrupt the spinning of the yarn upon the detection of a strand break.

    摘要: Apparatus is disclosed herein which detects breaks in spinning yarns in ring spinning frames or the like and in particular senses vibrations inherent to a yarn guide disposed on a bobbin when the yarn guide comes into contact with the spinning yarns. The apparatus achieves quick inspection of whether breaks occur with the spinning yarns by the presence and absence of the vibrations, thereby monitoring joints in the spinning yarns and the operating state of the spinning machine.
