    Figures 1-3 show the first example of an understanding of the sealing funnel 1, (g of the sealing tape, with a funnel column and inlet and outlet openings.
    The funnel for sealing the belt can be mated with a band-laying machine or it can be provided for gripping the carding cage
    The outlet funnel 1 has a step on which the measuring unit 2 is installed, which has the measuring channel o This unit consists of two parts, namely, channel part 3 and limiting (supporting) part 4 j between which the spring plate 5 is clamped. The latter serves as a measuring unit for measuring the thickness of the fiber tape passing through the funnel 1 for sealing the tape and the measuring channel.
    The channel part 3 has an approximately plate-like shape, and on its clamping surface has a guide groove; coupled with the channel of the sealing funnel 1. On the opposite surface, the channel part 3 has a centering edge 6, which runs transversely to the measuring channel and inserted into the corresponding groove in the stepped part of the funnel. Due to this, the channel part 3, and with it the entire measuring unit 2 is fixed in two coordinate directions relative to funnel 1. Fixation in the third coordinate direction, perpendicular to the image plane (Fig. 1), occurs with the help of two bolts 7 5 part 4 and through the slots 9 and 10 in - the leaf spring 5 or in the channel part 3 and the funnel 1 screwed into the screw holes 11. Since the bolts 7 simultaneously serve to fix the measuring unit 2 on the funnel 1-, the measuring part can be replaced with a simplereleasing and tightening the bolts, i.e. a device consisting of a funnel 1 and a measuring unit 2 can simply be matched with varying belt numbers.
    The plate spring 1 according to FIG. 4 consists of the measuring part of the beam 12 to the two torsion bars 13, with which the measuring

    the beam 12 is fixed to the bearing element 14. The laminate spring 1 consisting of the mentioned parts is made monolithic and clamped between the channel part 3 and the restrictive part 4 in the transition zone between the bearing element 14 and torsion bars 13 in two places, marked in Hatching 4 . The measuring part - beam 12 of the leaf spring 5 is located across the measuring channel and its longitudinal axis is perpendicular to the direction of movement of the tape, while it is limited by movement in the measuring channel at its ends using two support surfaces 15 of the restrictive part 4
    The tape coming out of the funnel 1 to seal the tape and passing through the measuring channel is compressed by measuring beam 12 in the measuring channel, and pressure is generated on measuring beam 12, the absolute value of which increases with the possibility of reproduction with increasing tape thickness. Each change in tape thickness results in a corresponding change in this pressure acting on the force measuring beam 12. Due to the supporting surfaces 15, the measuring beam 12 cannot deviate from the measuring channel, but bends, and in the measuring beam 12 a positive elongation occurs on its one surface, and a negative elongation proportional to the acting force and is a measure of its thickness on its other surface tapes. The mechanical elongation value by means of 12 strain gauges 16-19 mounted on the measuring beam is converted to an electrical value (Fig. 7).
    As can be seen from Fig. 2, the supporting surfaces 15 are less than 1 mm from the connecting bridge connecting portion 4, thereby limiting the possible maximum deflection of the measuring beam 12 to this value, and the named bridge between the two supporting surfaces 15 acts in as a limiter against excessive lengthening or overvoltage.
    Referring to Figures 2 and 3, in the restrictive part 4 along two side walls transversely to the measuring channel of the channel part 3 is inserted along a tube or nipple 20. The tubes are fixed each in one of the holes 21 penetrating the corresponding side wall. One of the tubes 20 serves to supply electrical connections, the other provides easy cleaning and simple cooling of the measurement site with compressed air. In this case, cleaning is performed by periodically supplying compressed air, and cooling - by continuously supplying compressed air.
    Both torsion bars 13, positioning the measuring beam 12 and having a stationary center of rotation, additionally prevent the latching effect when the measuring beam 12 passing through the fiber tape is heated, and thereby prevent the occurrence of mechanical stresses due to temperature fluctuations. To prevent the measuring beam 12 from wearing out with a fibrous tape, it is fitted on the side in contact with the fibrous tape with a pressure pad 22 made of solid metal or ceramic, mounted on the measuring beam 12. In addition to the strain gauges 16-19, a temperature sensor is provided in the measuring beam 12 or in its area. to account for possible temperature fluctuations (not shown).
    Figure 7 presents the principal placement of the strain gauges 16-19 on the measuring beam 12, as well as the evaluation scheme of their signals. The indicated drawing shows a measuring beam 12 supported on the supporting surfaces 15, on which the pressure pad 22 of which is exerted by a force F from a fibrous tape. To assess the elongation arising from this, on two surfaces of the measuring beam 12, two strain gauges were installed on each of them.
    The load cells are located symmetrically to the mental point of application of force F in the middle of the measuring channel (Fig. 5). This ensures complete compensation of interference caused by the ambient temperature or local heating of the measuring beam 12 due to the rubbing of the fibrous tape.
    Each strain gauge 16-19 has a specific electrical resistive10

    Lenpe R | (, and iu e L about t sawnuts are the same. Since h cgcnp, the relative change in oi port np during deflection of the measuring bank is 12, it is proportional to the elongation of tezidatch, then the definition of 7n can be done by i h-- This change is conformable to the match. This is accomplished with the aid of an unstl ghc scheme of the bridge type, consisting of four tetvens, formed by impedance with R included in the shape of the ring (D ° R (9 "-CJIF rcbeyb) to points sokgney between-resistance and R g and with one cyrone and R.J7 and R, g with RU1 -1 pntacse for the same Ug, then at the two other points of the connection, you can get a power supply voltage UA, proportional to the mismatch of my hectare, which is the same as the sum of the individual strain gauges from 16 to 19.
    Since the measurement is relatively short and has a greater stiffness coefficient and is not effective with Mctcov, then the sleep is measured with exponential frequency and makes it possible to measure short and even thickness; tapes at high speed passing voikgshgt MI tape. Proposed Device i. necr.t-shnit simple zone cornacoj funnel 1 for compaction by replacing the guide; t of the vial part 3), it is possible to place the measuring organ very close to the elongation of the fy yc; the possibility of simple cleaning of the transverse organ} protection of the measuring organ against external mechanical influences of the measuring beam 12 from excessive lengthening by installing a mechanical stop; the measuring body is practically independent of temperature fluctuations and largely independent of fluctuations of the linear density of the fiber strip,
    FIGS. 8–14 show the IGHO suppurative execution of a funnel 1 (Fig. 8, 9) with a HPC tape compaction, as well as with u-kgodzch for use with this hurry olorn (limited to 4 part 4 (FIG. 10,11) and fitted part-time chat pru / tsha 5 (Fig. 12-14).
    In principle, the funnel with the funnel shown in Figures 1-3, but has a Vocod profile of the Oral or Oval or oblong cross-section. This shape leads to a corresponding deformation of the cross section of the fibrous tape, so that the plate spring no longer abuts it tangentially, but abuts along the side surface.
    The funnel 1 also has, in the zone behind the outlet, a step on which the measuring unit is mounted and fixed with bolts (not shown), in it the channel part 3 is at the top, and the support part 4 at the bottom. Thus, directly to the ledge of the funnel 1, the supporting part 4 (figs. 10, 11) is attached, and the channel part 3 is located above it. The plate spring 5 (figs 12-14) is clamped between these two parts, and it is not essential that two parts - channel or support - will be installed directly on the ledge of the funnel 1.
    Plate spring 5 (Fig.12-14 consists of a thickened bearing element 14, forming its edge zones and the measuring part of the beam 12 connected directly at one end and the other end using a torsion bar 13 with a bearing element part 14. As in this case the plate spring 5 is made of the word

    on the connection of two different parts and on the border of two zones of the same part. The plate spring 5 has two holes for the bolts 7 (figure 1) of the corresponding bolt connections for coarse adjustment of the measuring unit. Precise adjustment is made by bolts through the second pair of holes and screwed into the corresponding threads of the bearing part 4.
    The measuring beam 12 in its area in contact with the passing and measuring fibrous tape has a thickening 23 with a pressure pad 22. Four strain gauges are installed on the surface of the measuring beam 12 opposite to the pressure plate 22, mainly in the zone between the thickening 23 and the end of the measuring beam 12 transition into the carrier element 14.
    The supporting part 4 (Fig. 10,. 11) is matched with the leaf spring 5

    and has on its edge an approximately V-shaped support surface 15 for the leaf spring 5, and also has a step 24 in the area of the measuring beam 12 offset relative to the support surface 15. The shoulder 24 is divided into two parts by an edge 25 located in the area of the pressure pad 22 ( 12). The rib 25 protrudes under the ledge 24, but lies deeper than the supporting surface 15, and forms an abutment limiting the deflection of the measuring beam 12.
    The support part 4 (Figures 10 and 11) has milling 26 and 27 according to the type of chambers. Cameras 26 and 27 enter by drilling 21, made in the corresponding side wall of the support part 4, and a tube 20 is fixed in at least one of the holes 21; Through this tube 20, through the chamber 26 and the step 24, electrical strain gauge connections are brought out. A hole 21 (not shown) is fixed in the hole 21 entering the chamber 26, through which compressed air is blown into the supporting part 4 from the outside to clean and cool the measurement point, which passes through the chamber 26 and rib 25 above the measuring beam 12.
    Plate spring 5 has a protective element 28 connected to the supporting element 14, while both elements are L-shaped. The measuring part 12 of the plate, the spring 5 is placed between the elements 14 and 28 with a gap and is connected on the one hand with the bearing element 14 directly, and on the other by means of a torsion bar 13.
    The device works as follows.
