摘要： The invention relates to a sensor system for the vector control of an electric synchronous motor using a microprocessor (MP), especially a permanent magnet motor (PM) of a thread feeding appliance (F). According to the invention, sector permanent magnets (11) which can be rotatably driven by the rotor (R) and have the same polarities are homogeneously distributed about 360°, at least two fixed Hall sensors (H1, H2) are aligned on the orbit of the sector permanent magnets, said Hall sensors being interspaced in the direction of rotation in such a way that each sector permanent magnet (11) at least temporarily activates at least two of the Hall sensors at the same time, and a zero permanent magnet (14) with reversed polarity is provided for bypassing at least one of the Hall sensors.

摘要： The invention relates to a detector (D) for detecting when the thread bobbin in a thread-processing system (S) has to be replaced. Said detector comprises a movably received element (E), at least one detection member (7) that responds to a relative position or a relative position change of the element with a signal (i), and a power generator that exerts a force on the element, and the element (E) can be adjusted during the replacement. The force is oriented in the direction of movement of the element (E) towards the detection position (P). The positioning device is provided with a thread clamping area (6, 6') that is arranged relative to the path of travel of the element in such a manner that the positioned thread (Y), until the replacement, forms a barrier for the element (E) against a movement towards the detection position (P) in response to the exerted force. The thread, during replacement, becomes detached in such a manner that the element (E) automatically moves towards the detection position (P).

摘要： The invention relates to a yarn feeding device (F) for weaving or knitting machines whose winding element (W) is driven by an electric motor (M) controlled by an electronic speed control device (CU). According to the invention, the electric motor (M) is a synchronous motor, in particular, a permanent magnet (PM) motor with the speed control device (CU) provided for effecting a permanent (continuous) vector control with the stator being sinusoidally acted upon. Continuously determined information pertaining to the relevant rotational position of the rotor (R) of the motor (M) is used in the speed control device (CU), which serves to perform permanent (continuous) vector control, in order to adjust at least one predetermined rotational position (X1, X2) of the winding element (W).

摘要： The invention relates to a yarn processing system (S) comprising a delivery device (F), a power loom (L), a controllable yarn tension device which is situated downstream from the delivery device, and a tensiometer which supplies a signal (f) that represents the yarn tension and which is arranged downstream from the yarn tension device. Said tensiometer comprises a separating device (P) which can be adjusted between a passive position and a separating position and with which a temporary separation between the tensiometer and the weft yarn (Y) can be effected in order to generate a yarn tension zero signal (f0) for a signal analysis device (G). In addition, the weft thread (Y) is temporarily separated from the tensiometer probe (7) during the interval between successive insertion operations, and a calibration (k) is carried out for a future control operation by using a yarn tension zero signal (f0).

摘要： The invention relates to a method for controlling the drive speed of a thread feeding device supplying a channel in a rapier loom or projecting weaving machine. According to the inventive device, the data on a future working phase of the weaving machine is transmitted in said channel by the main control unit to the weaving machine to a speed control unit of the thread feeding device in addition to signal data from an individual thread sensor and speed data of the drive motor. Said data makes it possible to calculate the amount of thread necessary for the working phase in said channel and the drive speed of the drive motor is deduced from the calculated amount of thread and correspondingly adjusted.

摘要： The invention relates to a device for the selective braking of a running thread (Y), comprising a controlled thread brake (1) having at least two brake elements (B, B') which can be elastically pressed against each other with an adjustable force that determines the braking effect. The thread (Y) runs between said brake elements. The device further comprises an actuator for the temporary passivation of the braking effect, a control device (C) to which the first actuator (M1) is connected and a device for adjusting the brake force. According to the invention the adjustment device is actuated by means of a second actuator ( M2), which is also connected to a control device (C), only in case of a passive braking effect.
