    In the continuous measurement and control of deviations in cross-section of slivers with constant relative sensitivity which is independent of the adjusted set value with respect to this set value, the sliver is guided between a grooved roller and a feeler roller which contact each other in the absence of the sliver between the grooved roller and the feeler roller. The changes in the position of the feeler roller are converted into rotational movements of a lever shaft and thus into changes of direction of a measuring tab. The measuring tab is arranged eccentrically on the lever shaft. A sensor is movable by means of a lead spindle which is perpendicular to the lever shaft and lies in a plane determined by the lever shaft and by the axis of the feeler roller in the absence of sliver between the rollers. This sensor preferably has a magneto-resistor. The changes in direction of the measuring tab are, therefore, transformed into fault signals of the magneto-resistor, the fault signals being used to control the thickness of the sliver.

    The invention relates to the textile industry and is intended to control the thickness of a fibrous material, such as a tape. Devices are known to control the fiber matte {s), the measuring rollers, one of which is installed with, the possibility of reciprocating motion, and through a lever with a sleeve are kinematically connected with the angle converter of the lever to electrically signal. The main disadvantages of the known device are low measurement accuracy and maintenance complexity. The purpose of the invention is to improve the accuracy of measurement and control of service. The goal is achieved by a device that contains the measurements. teller rollers, one of which is installed with the possibility of reciprocating movement and through a lever with a sleeve, is inematically connected with the angle of rotation converter | It has a micrometric screw, is kinematically connected to a transducer of rotation angle into an electric signal, and the axis of the sleeve is located eccentrically to the axis set with the possibility of returnable movement of the roller. The transducer of the angle of rotation of the lever into an electrical signal turns on the magnetic plate, and the lever. made of ferromagnetic material. In this case, the device has two rulers with scales mounted parallel to the micrometer screw and the transducer of the lever angle to electric signal includes an indicator arrow, while the scale of one ruler is linear and programmed in absolute values of the thickness of the fibrous material, and the scale of the other ruler the nonlinear is calibrated in terms of the percentage of its changes in the thickness of the fibrous material from the nominal value of one turn of the micrometer screw. FIG. 1 shows a simplified kinematic diagram of the device; in fig. 2 - Static: | 1C; ar 3 and 4 are two projections of an embodiment of the device; Figures 5 and 5 are the variants of the location of the transducer of the angle of rotation of the raiaga into the electric one along the length of the micron {xkGe Screw.,. The controlled material (tape) 1 (Fig. 1) is located on the mezkyu and the measuring rollers 2 and 3. The roller 3 is mounted with the possibility of reciprocating motion. The axis of the role-. 3 through lever 4 is kinematically connected to the axis 5 of the bis bearing by a spring. .7. The static characteristic (Fig. 2) of the device’s linear system (straight dt) is the "{change and A rt of the angle of the rotary lever 4 relative to the axis of the micrometer screw 8 in the junction (Schenie D L p л 4) relative to the transducer 9 of the angle of rotation of the rachaga into an electrical signal. / The device (Figs. 3 and 4) consists of a crank of the measuring rollers 2 and 3. The axis of the hub 10 connecting the axis of the roller 3 to the lever 4 is located eccentrically to the axis of the roller 3 with a certain amount of eccentricity 11 Sleeve 110. Installed in the sub-12. Microm The tric screw 8 is installed with BJ bearings 13 and has a handle 1, the screw 8 has a converter 9 of the angle of rotation of the gear 4 into an electric signal. The converter 9 is mounted with the ability to move along the length of the screw 8, is filled with an inductive cable and turns on the magnetic plate 15. The lever 4 is made of ferromagnetic material and is associated with the axis of the sleeve 10 through the lever 1 6. The imeeT device has two rulers 17 and 18 with scales (Fig. 5 and 6}. The ikala 17 is linear and calibrated in absolute values of the thickness of the fibrous material, and the scale 18 is non-linear and graduated. in the values of the percentage change. Sh9 | of the fibrous material from the nominal value of one revolution of the micrometer screw. The Converter 9 includes an index arrow 19. The device works. The next image. The controlled material 1 moves in the direction T1 shown {(Burner (Fig. 4J. Depending on the change in the thickness of the material the measuring roller 3 moves. Moving the roller 3 converts to the angle of rotation of the sleeve .10, which, in turn, turns into movement piiPiara 4. The movement of the lever 4 is perceived. It is smeared by the transducer 9, on the input of which an electrical signal is produced, depending on the value of the tozdine of the material being monitored. position transformation. ers 9 relative to the arm 4. Moving preo6 {9} aeovatep along the length of the micrometer screw 8 is effected by rotating the handle 14.
    To increase the measurement sensitivity, the transducer 9 must be shifted to the right, and to decrease to the left.
    To ensure a linear dependence of the output signal of the device on the change of the Lciv of the monitored material, the eccentricity 11 serves. The choice of the eccentricity value and measurement sensitivity is determined by the type of fibrous material and the threshold of variation of the roll of the roller material from the nominal value.
    The nptebbpasoBaTeJib 9 has a pointer 19. The scale 18 is priogradirovana in absolute values of the thickness of the material being controlled. If the sensor is to record the deviations of the material thickness from the nscale value / pointer 19 together with the transducer 9 is set opposite the scale value 17 corresponding to the nominal value of the monitored material.
    To correct the measurement process, the scale 18 serves. By displacing the pointer along the micrometer screw by rotating the handle 14 and setting it opposite the corresponding scale division 18, the trigger point of the converter 9 can be changed by a specified amount (percent), and therefore the AND of the controlled sign 5 can be changed thickness of measured material i
    The advantages of the proposed device cTSa compared with the known. . They consist in improving the accuracy of thickness measurement and facilitating maintenance.
