摘要： PROBLEM TO BE SOLVED: To provide a yarn tension sensor for repeatedly detecting the tensions of a yarn during the operation of a loom and always constantly maintaining the position tension of the yarn, to provide a yarn feeder equipped with the yarn tension sensor, and to provide a method for calibrating the tension of the yarn. SOLUTION: This loom yarn feeder 1 for feeding an elastic yarn has a yarn tension sensor 5 equipped with a calibration device. The calibration device 40 separates the yarn 7 from a pin 21 contained in the yarn sensor 5 in a possible time, especially in a yarn-feeding time without obstructing the operation of the feeder 1. When the yarn 7 is separated from the pin 21, the yarn tension sensor 5 is calibrated to zero. The zero point drift of the whole sensor system containing a measurement circuit can thereby be detected, and the tension of the yarn can be calibrated.

摘要： PROBLEM TO BE SOLVED: To provide a device and method for feeding thread for feeding an elastic thread to a thread consuming section where consumption of thread varies by the hour, in an amount corresponding to the time-varying consumption while keeping a tensile force of the thread constant. SOLUTION: A thread feeding device which feeds an elastic (soft) thread 1 to a thread consuming section where thread consumption varies by the hour has a controlling unit 18 for detecting and outputting an actual thread consumption. In accordance with this thread consumption, a thread feeding wheel 16 is driven at a rotation speed corresponding to the thread consumption. The thread 1 passes through a tension device 15 to reach the thread feeding wheel 16. The tension device 15 is adjusted so that it extends the thread by a predetermined amount to apply a predetermined tensile force to the thread 1. Consequently, it is possible to make a relation between a desired thread feeding amount and a rotation speed of the thread feeding wheel 16 fixed.

摘要： PROBLEM TO BE SOLVED: To provide a thread brake and a thread feeding device using the thread brake in which almost no dirt is accumulated as well as the structure is simple and the cost is low, the cleaning can be carried out simply, the component parts can be overhauled and assembled when necessary, and at the same time, it is guaranteed that the thread is braked perfectly evenly in a long service period. SOLUTION: A thread brake furnishing two disk form or plate form brake disks 10 pressurized elastically each other has a substantially U-shaped holding member 19 furnishing two legs 21 which pass both sides of the brake disks 10 providing an interval. To this holding member 19, a support pin 20 for brake disk is formed at least at one leg 21, or it is fixed by at least one supporting member connected thereto. At least one brake disk 10 has a center opening 44, and the support pin 20 penetrates this center opening 44.

摘要： The invention relates to a thread feed device (1) for a textile machine (3), comprising one or several motors (26, 52), which are controlled in a manner dependent on a signal derived from the textile machine (3). The control of the motors preferably occurs with a non-linear dependence on the control signal na. Furthermore, other signals are preferably linked with the control signal na. According to the invention, should there be several motors to drive the thread feed device with one belt, the motors should cooperate groupwise, whereby just one motor (26) of the group is position-controlled and takes over control as master motor. The other motors (52, 52a) etc. support the master motor by generating a corresponding torque, following the above, according to the positioning thereof and thus work as slave motors. Each individual measure improves the match of the delivered thread amount to the actual requirements and thus reduces the formation of sections with stitching of different size to that required or other quality problems, in particular, on altering the speed of the textile machine. The total measures permits complete avoidance of sections of different size stitching, or the effects of other parameters on the length of the stitching.

摘要： The tensioner has convex-faced washers (10) pressed together, passing the thread, with a central opening (44) through which bearing pins (20) pass and upon which the washers rotate. A U-shaped holder (19) has limbs (21) either side of the tensioner, which carry the bearing sections. An Independent claim is included for the yarn supply unit, including the tension controller and supply drum. Preferred features: The holder is a bent piece of wire including formed bearing eyes. It has two parallel sections with adjustable projection from its mounting (14). One end of the holder is oscillated under spring loading, coupled into the holder. One of the limbs is bent or offset. The bearing is detachable from the holder and adjustable on it. The bearing section is approximately U-shaped. Its frame is clipped onto the holder. It can be held fixed in a working position, or folded-back. A region on the frame (40) supports the tensioner. The frame is detachably clamped to the holder and has divided construction. Further structural details include the plastic bearing section, earthing and thread guidance.

摘要： A yarn feeder device for feeding elastic (soft) yarns to a yarn consuming station whose yarn demand fluctuations over time has a control unit which ascertains the current yarn demand or to which the current yarn demand is reported. In accordance with this demand, a yarn feed wheel is driven at a rotary speed suitable for the yarn demand. The yarn travels via a tensioning device to the yarn feed wheel. The tensioning device is arranged such that the yarn is stretched in a defined way. As a result, a fixed association between a desired yarn feed quantity and the rotary speed of the yarn feed wheel is possible.

摘要： PCT No. PCT/DE96/01751 Sec. 371 Date Apr. 2, 1998 Sec. 102(e) Date Apr. 2, 1998 PCT Filed Sep. 17, 1996 PCT Pub. No. WO97/13906 PCT Pub. Date Apr. 17, 1997For 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. The controller may be designed such that it functions as a closed-loop status controller and intermittently as an open-loop controller. Other provisions, such as disturbance variable compensation, parameter adaptation, or the like, are possible.
