    The weaving machine has a weft picking mechanism which is controlled so as to adjust the picking speed of the weft yarn relative to the operating speed of the weaving machine. The means for controlling the picking mechanism receives an error signal from a comparator connected on the input side to a pick-off for detecting the arrival of a weft yarn at the weft catching station and a second pick-off for detecting the operating speed of the machine. The error signal may also be used to control a fluid type of weaving machine or may be used to control the drive of the weaving machine relative to the picking mechanism.

    The invention relates to the textile industry, namely, devices for controlling the speed of laying the weft yarn on a weaving machine. A device for controlling the speed of laying the weft yarn on a loom is known, which contains sensors for the position of the weft yarn and the main shaft of the weaving machine, connected to the corresponding inputs of the comparison element, and drives the mechanism for weaving the weft yarn. A disadvantage of the known device is the complexity of the design. The purpose of the invention is to simplify the design. The goal is achieved by the fact that in the device containing the position sensors of the weft yarn and the main shaft of the weaving machine, connected to the corresponding inputs of the comparison element, and the drive of the damming mechanism, the weft yarn is installed, the position sensor of the weft yarn is installed at the pickup location the output of the comparison element is connected to the drive of the weft yarn mechanism. Fig. 1 shows the structure of a device mounted on a microloom weaving machine; Fig. 2 is the same on a pneumatic (or hydraulic) weaving machine. The sensor 1 of the position of the weft yarn (figure 1) is installed at the position conventionally indicated by the position 2, trapping the weft thread by the take-up mechanism (not shown). The weaver's position 1 sensors and the position 3 of the main shaft 4 of the weaving machine are connected to the drive 6 of the weft threading mechanism 7 through mechanism 5. The mechanism 7 includes an installation bolt 9 kinematically connected to the torsion shaft 10, which ensures the use of the micro-arc 11. The main shaft 4 has a switching element 12 communicating with sensor 3. In the case of using the device on a pneumatic (hydraulic) weaving machine (FIG. 2), the actuator 6 is designed as a pressure reducing valve, and the laying mechanism is The exact thread contains a source 13 of compressed air (liquid), a main nozzle 14 and a relay nozzle 15. The device contains a brake 16 controlled by an actuator 17. The output of the comparison element 5 is connected to the actuators 6 and 17. The device operates as follows. With the passage of micro-lash 11 with the laced thread 8 (Fig. 1) near the sensor 1, the latter gives a signal to the first input of the comparison element 5, the second input of which is connected to the output of the sensor 3 of the main shaft 4, If the signals from the sensors 1 and 3 come to the element 5 comparisons at the same time, the weft speed is equal to the required one. If the signal from sensor 1 arrives at the input of the comparison element 5 earlier than the signal from sensor 3, then element 5 outputs a signal to the actuator 6, providing a reduction through the bolt 9 and the torsion shaft 10 to reduce the speed of the microarray 11. If the signal from sensor 1 goes to the input element 5 later than the signal from sensor 3, the comparison element 5 by means of actuator 6 increases the speed of the micro-lens 11 carrying the weft thread 8. When using the device on a pneumatic (hydraulic) (Figure 2) loom, changing the speed of laying the weft thread 8 (in head ing on the output signal of the comparing element 5) is performed by varying the pressure (through the actuator 6) supplied to the nozzles 14 and 15 or the actuator 17 to the brake 16. Economical effect of the use of the invention is defined by the simplicity of the device structure.
