    The adjustment of the density of the fiber layer in carding machines and the like is based on the measurement of the torque used for driving the licker-in (4) or the drum (8). A signal corresponding to the torque is compared with an order value which may be adjusted as desired or which is provided by a measurement member for measuring the weight of the band or which is a combination of the two. The measurement of the torque is effected by measuring the power absorbed by the licker-in and/or the drum, or by measuring of the torsion of a torsion bar, or by measuring the sliding of a variable clutch.

    11 The invention relates to a textile industry, namely to devices for adjusting the linear density of a tape on carding or card machines. The purpose of the invention is to improve the accuracy of regulation. FIG. 1 shows a block diagram of the proposed device; Figs. 2 and 3 show variants of torque sensor execution. A device for adjusting the linear density of a tape on a carding card (or carding machine) consists of a feed drum t, a feed fiber material 2 and having a drive (electric motor) 3. The shaft 4 of the preliminary combing machine of the machine has a drive (electric motor) 5. Torque sensor, indicating which depends on the value of the linear density of the material 2 can be made in the form of a resistor 6. A layer of fiber 7 enters the surface of the main drum 8, which has a head 9 and is kinematically connected with a drive (electric by the driver) 10. The fiber is removed from the surface of the main drum 8 by means of a removable drum 11 and transported using rollers 12 and 13. The value of the linear density of the fiber formed in the tape is controlled by means of a measuring funnel 14J installed in front of the rollers. 13. Drum 11, The rollers 12 and 13 are kinematically connected to a drive (electric motor) 15, which also sets the paver 16. The output of the torque sensor (resistor 6) is connected to one input of the reference element-17, the other input of which is connected to the output of the reference a torque made in the form of a potentiometer 18. The connection of the potentiometer 18 to the comparison element 17 is performed via a switch 19. The output of the comparison element 17 is connected to the drive 3 of the feed drum 1 via the control unit 20. The device may also contain an additional comparison element 21 the inputs of which are connected respectively to the output of the measuring funnel 14 and to the output (U {) of the setter with a density ruler (not shown). The output of the comparison element 21 through the integrator 27 can be connected 0 via the terminal 23 of the switch 19 to the input of the comparison element 17. The terminal 24 of the switch 19 is used to connect the potentiometer 18 to the input of the comparison element 17. The torque sensor can be made in the form of a torsion bar 25 (Fig. 2), the end of which is kinematically connected with the shaft of the main drum 8 and the shaft 4 of the pre-comb. The torque sensor can also be made in the form of an electromagnetic clutch 26 (FIG. 3), the input and output shafts of which are kinematically connected respectively to the shaft 4 of the pre-comb and the shaft of the main drum 8 of the machine. When performing a torque sensor in the form of a torsion bar 25 as a drive 1. of the main drum 8, removable drum 11 and shaft 4 of the pre-comb, it is advisable to use. common motor 27. When performing the torque sensor in the form of an electromagnetic clutch 26, it is advisable to have a common drive 28, kinematically associated with the drums 8 and 11. The device works as follows. A torque sensor, implanted in the form of a torsion bar 25 or in the form of an electromagnetic clutch 26, produces at its output a signal depending on the linear density of material 2 fed to the input of the feed drum 1 of the machine. If a torsion bar 25 is used as a torque sensor, the magnitude of the torque, and hence the magnitude of the linear density, depends on the twist angle of the rod 25. The magnitude of this angle can be recorded using an angle-to-electric signal converter (not shown) . If an electromagnetic clutch 26 is used as the torque sensor, the torque value can be estimated by the slip slip value detected by known means. If the linear density is greater than a predetermined, determined by the level of the voltage U, taken from the output of potentiometer 18, the signal from the output of the torque sensor increases, i.e. the signal increases from the output of the torsion bar 25 or from the output of the electromagnetic clutch tuitf from the output of the electromagnetic clutch 26. As a result of comparing the signals U and UJ, a difference signal is formed at the output of the comparison element 17, which, after passing through the control unit 20, reduces the rotational speed
    2h
    drum 1. If the linear density of the material is less than the specified, then at the output of the comparison element 17 a signal JkU is formed, which, having passed through block 20, increases the rotation speed of the drum 1. Thus, the same amount of fiber is fed to the machine entrance results in alignment of the linear density of the tape at the exit of the carding or carding machines.
