    Web unwound from a supply roll is slit into a plurality of bands by a slitting unit comprising circular disc blades. The individual bands are subjected to tension by a brake roll assembly positioned before the take up roll to hold the individual bands taut with a predetermined braking force in such manner that different degrees of slippage relative to the brake roll and the individual bands are effected.

    2. Brake roller for tensioning several parallel-running belts, containing a stationary or water shaft, the cavity of which is connected to the power cylinder, travel rings mounted on the shaft with a possibility of sliding, and brake elements in contact with the rings, mounted on the shaft on an elastic cushion, formed by the pressure of the working agent of the power cylinder with the possibility of adjusting their position depending on the tension of the bands, on l and -. U ay u u and with the fact that he has
    mounted on the shaft and in contact with the running rings holder with radial grooves located along its side surface, and the braking elements include segments placed in the grooves of the holder coaxially relative to the running rings, pushed so that their axial length is less than the axial length of the running rings and mounted symmetrically relative to the latter, the axial length of the sections of the rings free from contact with the segments exceeds the length of the segments.
    The invention relates to the field of winding lengthy ribbon-like materials, in particular, in the process of cutting roll materials on tapes.
    A brake roller for tensioning several parallel-running belts is known, comprising a stationary or drive shaft, in which there are several running sliding rings arranged one near the other, and brake elements mounted on the shaft with the possibility of contact with the rings tl}
    The disadvantage of this roller is the rapid and uneven wear of the drive shaft, which at high speeds of rotation of the brake rollers causes significant fluctuations.
    Also known is a brake roller for tensioning several parallel-running belts, comprising a stationary or drive shaft, the cavity of which is connected to the power cylinder, running rings mounted on the shaft for sliding, and brake elements in contact with the rings mounted on the shaft on an elastic cushion, formed by the pressure of the working agent of the power cylinder with the possibility of adjusting the position of the brake elements depending on the tension of the belts 23.
    A disadvantage of the known device is the short roller life.
    The purpose of the invention is to increase the interest rate; ka service roller.
    The goal is achieved by the fact that in the brake roller, for "pressing several parallel-running belts, containing a stationary or driving shaft, the cavity of which is connected to a cylinder, running rings mounted on the shaft with a possibility of sliding and brake contacting the rings the elements mounted on the shaft on the elastic cushion formed by the pressure of the working agent i of the power cylinder with the possibility of adjusting the position of the brake elements depending on the tension of the tapes, 5 the shaft has radial grooves located Along the lateral surface, and t, the or- ganic elements include the segments placed in these oaxi grooves.

    (The drive shaft, the cavity of which is connected to the power cylinder, the running rings mounted on the shaft so that it can slide, and the brake elements in contact with the rings, mounted on the shaft on an elastic cooler, by the pressure of the working agent of the power cylinder can be adjusted to depending on the tension of the belts, has a holder mounted on the shaft and in contact with the running rings of the holder with radial grooves arranged along its lateral surface, and the tortotoHMe elements in the VC heel segments, Arranged in the grooves of the cage coaxially with respect to the running rings, so that their axial length is less than the axial length of the running rings, and mounted symmetrically with respect to the latter, while the axial length of the segments of the rings free from contacting with segments exceeds the length of the segments. Figure 1 shows a diagram of an installation for cutting a coil into tape, a view of FIG. 2, a diagram of a cutting installation, a top view of Fig. 3 braking roller, a cut; FIG. Section A-A of Fig. 3; in Fig. 5, the second variant of the brake, roller | roller, the section in fig. Fig., 5. . The cutting installation (Figures 1 and 2j consists of a reel G carrying on itself an unwinding tape 2, a support roping 3 located in front of the motoSil 1 in the direction 10 of the movement jfeHta, a longitudinal cutting device which consists of several pairs of circular circular knives and 5 6, a combination of brake rollers 7 .9 and a winding roller, 16, reeled off the reel .1 the tape 2 is divided by a cutting device k, S into a tape that are parallel to the fljayr to other tapes 11-13 which are between the cutting device A, 5 and directed by the roller 6 to them Different sagging is achieved due to the different diameter of “a-. mat / left bands caused by different thickness cents rewind; my on the reel 10. G using the combination of brake rollers 7-9 mounted in front of the winding reel 10, through which individual belts 11-13 pass through each individual belt, individual tension is reported. The combination of brake rollers is set in motion in such a way that they spin at a lower speed than the slowest moving tape. D, “The brake shown in FIG. 3 and k, the roller consists of a shaft U, in which the axial direction 8 is freely fitted: the running rings 15 are mounted along the shaft. Between the discs 16, or14, which cut the roller from the end sides, the running rings 15 are located. The running rings 15 carry a layer 15 of rubber or other material on their outer surface in order to tension the belts without slipping them. Driven or braked shaft 1 has four radially open channels 17 in its outer zone, in which hollow elastic shells 18 are placed, connected by channels 19 and rotating fitting 20 with a source of compressed air, and brake elements 21. When the brake works, due to the filling of the shells 18 with compressed air through a rotating under-. the connecting nipple 20, the brake elements, are pressed radially against the corresponding inner surface of the running ring 15 and cause uniform braking of all running tail plates 15 in the circumferential direction while aligning the slip. The brake roller shown in FIGS. 5 and 6 is similar in principle to the brake roller shown in FIG. 3 and. Additionally, the shaft 14 is fixedly mounted sleeve 22; which has radial orifices for disintegrating by force-closing the brake elements 23. The brake elements 23 have a width narrower than they are towards the driving ring 15. Due to this, the driving zones 2 are separated in the axial direction, 25 separated from each other by the brake zone. . In Figure 3 and U, brake elements 21 are located along the entire width of the travel ring 15. In this case, the stability of the running surface 26 wa | U-, 1G ... and software "Chip 27 Torl Y. and brake surface 27 of the braking element 2J" must . above, than the resistance to the bearing of the 15 and the predetermined minimum ratio of the arc length of the undercarriage zone 26 and the arc length of the brake zone 27 should be observed. Tsa 5 and 6 most wear out the „„ „. ,, chpi,. / h part is the running ring 15 least wear sleeve 22 and the brake element 23. Each. the brake element 23 (FIG. 5) occupies only about a third of the axial width of the running ring 15, due to
    91050561
    of which only the narrow middle section 25 is subject to wear, and the outer zones 2C are subject only to pure running wear. Due to the sharp separation of the - in the zone of braking 25 and the running zones 2, the running ring 15 has a long service life until it reaches the maximum level and
    maximum allowable guide gap.
    The proposed brake roller 5 can be used for winding and unwinding devices.
