  • Publication number: 20080256983
    Abstract: The invention relates to a control unit for thread feeding devices, such as those associated with knitting machines and the like. The control unit generates pattern or switch data control signals based on a pattern memory, or otherwise, for the thread feeding devices. In an embodiment of the invention, the control unit adds to or subtracts from the pattern data any advance or lag angles as necessary to account for the structure of the machine and to thus assure effective thread feeding.

  • Publication number: 20070278054
    Abstract: The yarn brake (1) according to the invention comprises individually adjustable biasing means (21, 22) which cooperate with plates (8, 9). By adjusting both biasing means (21, 22), desired positions of the brake plates (8, 9) may be deliberately set in a manner other than in conventional yarn brakes. For example, a desired centered position may be preserved for any yarn tension. It is also feasible to shift the desired centered position on purpose by deliberately adjusting both biasing means. The setting of the yarn tension is thus independent from the setting of the centered position.

  • Publication number: 20070272784
    Abstract: A yarn delivery device is provided with a motor-driven yarn delivery wheel, wherein the rotated position of the yarn delivery wheels is detected with high precision by means of an angle encoder. The angle encoder has at least a resolution s which is greater than the circumference of the yarn delivery wheel, measured in millimeters. The resolution s is preferably greater than five times (preferably 5.24 times) the value of the diameter of a winding of the yarn delivery wheel. The yarn delivery wheel is preferably looped by several (three to twenty) windings.

  • Patent number: 6832496
    Abstract: In order to monitor/adjust production in a circular knitting machine including several knitting systems and several yarn feeder devices, yarn is fed to active knitting systems from several supply devices operating according to at least two different yarn feeding principles, and in a non-positive manner. The individually fed amounts of yarn are continuously measured by means of scanned real rotation signals of the feeder devices. In order to obtain monitoring information and/or adjustment measures, comparisons are made with corresponding set amounts of yarn within at least one range of tolerance, the extent of which is adapted at least to yarn quality and/or yarn path parameters.

  • Patent number: 6125663
    Abstract: A method and apparatus for monitoring the scanning conditions when controlling a yarn feeding device including a storing surface for the yarn, a drive motor, a sensor device having at least one sensor oriented towards a scanning zone defined in the yarn feeding device, and a control circuit connected to the sensor device. The sensor generates an object-output signal for control purposes in response to the movement, absence or presence of an object in the scanning zone. A test signal is formed from and substantially synchronously with the object-output signal, and the signal level of the test signal is compared with an alarm threshold value representing a just barely acceptable deterioration level of the scanning conditions. An alarm signal is generated when the signal level of the test signal falls below a predetermined threshold value.

  • Patent number: 6105895
    Abstract: A yarn feeder intended particularly for flatbed knitting machines and elastic yarns has a yarn tension sensor which is provided with a calibration device. This device lifts the yarn from a peg that is part of the yarn tension sensor, at times in which this can be done without impairing operation of the yarn feeder. Such times are preferably time slots when no yarn feeding is necessary. Once the yarn has been lifted from the peg, a zero point calibration is performed. Zero point drifting of the entire sensor system, including its measurement circuit, can be detected and compensated for.

  • Patent number: 6080035
    Abstract: A climbing top has two shells connected by an axle assembly, wherein at least one of the shells comprises a hub member receiving the axle assembly and a rotor member extending radially outwardly of the hub member with respect to the axle assembly. The rotor member is mounted on the hub member with a direct snap-on connection which prevents axially outward displacement of the rotor member with respect to the hub member.

  • Patent number: 6010052
    Abstract: For supplying yarns, a yarn supply apparatus is contemplated that is designed particularly for knitting machines whose yarn demand fluctuates greatly over time. The yarn supply apparatus has a rotor-driven yarn wheel, which in the ideal case furnishes yarn directly to the knitting machine or its yarn guides without the interposition of yarn storage devices. The yarn tension is monitored by means of a yarn tension sensor, which provides measured value detection for a closed-loop controller that controls the supply by the yarn wheel. The controller is also embodied such that it can process signals that contain information about the future yarn demand. Thus in the event of imminent drastic changes in demand, of the kind that in flatbed knitting machines periodically occur at the edges of the knitted goods (turning points of the yarn guide), the controller can react by presupplying yarn or by ceasing to supply yarn. Yarn tension spikes and overly steep yarn tension drops can thus be compensated for.

  • Patent number: 5765399
    Abstract: For determining the movement of a thread supply boundary on the storage surface of a thread storage and feed device, different scanning properties of at least two circumferentially offset circumferential sections of the storage surface are scanned simultaneously and converted into storage surface signals which are nonidentical among themselves and which are discriminated from thread signals which are identical among themselves. The thread signals are generated by sensors which scan a scanning zone on the storage surface and formed on the basis of a scanning property of the thread windings when the thread supply is present in the scanning zone. The thread storage and feed device is provided with first and second circumferential sections on the storage surface differing from one another with respect to their scanning properties, and a plurality of sensors.

  • Patent number: 5499219
    Abstract: An electro-acoustical transducer arrangement for underwater antennas comprised of a plurality of hydrophones (10) which are arranged at equal distances in a linear array, and are to be disposed vertically above each other on a support. For reasons of a simplified assembly along with good receiving properties, the hydrophones (10), together with a reflector (11) disposed behind them in the direction of incoming sound, are embedded in an acoustically transparent rigid cast enclosure (20) of an elastomer, preferably polyurethane, which can be worked in a casting process. The connecting lines (12) of the hydrophones (10) of the enclosure 20 are combined in a common plug (13), which is accessible on a front end of the rigid cast enclosure (20). The rigid cast enclosure (20) is provided with devices for fastening the enclosure to the support.

  • Patent number: 5283623
    Abstract: In a method and system for the detection of faults in a length of textile fabric, the length of fabric is continuously scanned by an electro-optical sensor head. Light detectors located in a strip-form sensing zone of the sensor head are assembled in groups and emit group-specific fault signals. These fault signals are analyzed multi-dimensionally for the identification of spot faults and/or long faults, the criteria for analysis being the signal amplitude, the signal length, the recurrence of the signals and their periodic repeat at each revolution of the machine. Display, control counter devices and the like are energized as a function of the result of the analysis.
