    non-circular rolls are followed when the accelerator roller is spinning, as it does not affect the measuring sensor of the roll. For this reason, at the moment of gluing, the circumference of the roll is somewhat lower than the speed of the tape. The difference depends on the non-roundness of the corresponding roll; therefore, in practice, it cannot be co-pensyrozan. Due to the difference, the distance, the circumferential speed of the roll, and the speed of the tape at the moment of gluing onto the tension of the tape increases in a pulsed manner, the place of gluing is heavily loaded on tension, and the whole gluing process becomes unreliable. The object of the invention is to improve the quality of unwinding material and its gluing. The goal is achieved by the fact that the proposed device has a bistable multivibrator, whose input is connected to the output of the comparing unit, and a time delay block whose outputs are connected to the disconnecting dimming unit and one of the inputs of the comparing block, while one output of the Multivibrator is connected to the input b time delay, and the other with one of the inputs of the shutdown unit. Figure 1 shows the kinematic diagram of the device described; in fig. 2 - block diagram, devices; in fig. 3 - diagrams time roll speed acceleration. The device contains: -5t roll 1, an accelerator roller 2, which is driven through a drive 3, for example an acceleration engine, and is connected to a peripheral speed sensor 4, for example a tachogenerator, to measure the actual value of the acceleration roller's 2 circumferential speed. The guiding mechanism (not shown) over a pair of deflecting rollers 6 leads the measuring sensor 7, for example, a tachogenerator that serves to determine the peripheral speed of the deflecting rollers 6. The peripheral speed of the deflecting rollers corresponds to the tape speed is the driving force for the circumferential roll speed The gluing point 8 on the coil, but corresponds to marking 9 at the end of the roll. The marking 9 is read by the probe 10 when the roll is rotated, only if the circumferential speed of the roll 1 agrees; With the speed of the tape 5, the gluing mechanism is activated. The voltage of a given value U of the measuring sensor 7 (gauge) and the voltage of the actual value of and sensor 4 are supplied to the comparison unit 11 (Fig. 2). which, via a bistable interface 12 n delayed time block 13, is connected to a disconnecting block 14. In FIG. Figure 3 presents a diagram characterizing the operation of the device, where curve 1 shows the change in speed during acceleration of an ideally round roll by means of an acceleration roller 2, and curves 11 and III show the change in speed during acceleration of a non-round roll. The device works as follows. The voltage of a given value Uj from the sensor 7 to the voltage real: th value U | from sensor 4 are fed to comparing unit 11. Acceleration peaks (curves II and III of FIG. 3) explode so that the accelerator roller 2 is relatively weak on the surface of roll 1, and due to the roundness of the roll slips. In this case, the prologue 3 acts on the acceleration roller 2, and the sensor 4 loads the comparing unit 11 more strongly than with a load of roll K}; a 2 rolls 1 Because of this, the voltage of the measuring time sensor does not correspond to the peripheral speed actually existing on the circumference of the roller. The signal issued by the comparing unit 11 (point A in FIG. 3) through the bistable multi-selector 12 enters the unit in ;; er qi time 13, which forces the comparing unit 11 to delay the following signals for a certain time until actuator 3 operates with a time delay from the disconnecting unit 14 (see point B on curve III of FIG. 3). If the roll speed is greater than the speed, 4eiM speed is lenga, then the drive 3 is turned off, and the accelerator roller 2 and roll 1 due to the effect of the friction forces begin to rotate more slowly. At the same time, the accelerator rskk 2 also jumps and explodes more bruises to the wounds, but aa aie the USI.LI drive and PI1Sh no longer appear in curve III, at the point (speed) the tape speed to the circumferential speed, the roll is matched again, comparing the faded 1 1 vygdyat second signal through Ipti 12, switched and another element of the shutdown unit 14, which already stops the probe 10 gluing. Form;. Of the invention. The device of the frame and the rolled material containing an accelerating roller with a sensor of its circumferential speed, kinematically associated with a driving mechanism, a glue detection probe, rolling macanism with a system of deflecting rollers, one of which is kinematically connected with a tape speed adjuster.
