    FIELD OF THE INVENTION The invention relates to the etaJgpyp industry, in particular, to a device for securing rolls in a sheet heat treatment machine. A device for securing rollers in a furnace for heat treatment of a sheet is known, comprising frames, supports and an elastic coating on rollers 1. The closest in technical essence is a device for securing rolls in a machine for thermal processing of a sheet, containing frames with rolls and bearing supports of rolls with bearings. The device consists of a lower frame on which a set of lower rolls is mounted, and an upper frame with a carrying set of upper rolls, the upper frame moving in a vertical plane relative to the lower frame. Due to the possibility of such movement of the upper frame, the distance between the rollers can be adjusted either to adjust the sheet processing machine of a certain thickness, or so that the machine can simply work as a roller conveyor if it is not necessary to perform cooling operation 2J. The disadvantages of the known devices are that, as a result of the deformation of the sheet before or during processing, the thickness of the sheet will be greater than the spacing between the rollers, which will cause significant stresses that can lead to the breakdown of the machine for processing the sheet. For some free rolls, the tightness problem becomes more complicated. The purpose of the invention is to increase reliability and tightness. I The above objective is achieved by the fact that in the device for mounting the rolls in the heat treatment machine, the sheet containing the frames with the bearing roll supports and bearings, the device is equipped with a suspension mounted on one of the frames by means of preloaded elastic gaskets and sealing gaskets, one of which a roll is supported by the corresponding roll, and the other is between the roll support and its corresponding frame, while the support is fixed on the suspension. In addition, the device is provided with brackets, in one of which the bearing cage of the corresponding roll is mounted, the other connects the suspension with its corresponding frame and core, and the suspension is equipped with plates connected to the bearing cage by means of a threaded pin with nut and bushings, while the core installed between the suspension plates through pre-loaded elastic pads. The roll support is provided with a ring connecting the roll support to the bearing sleeve and the skirt located between the roll neck and the corresponding frame, while a sealing gasket is located between the skirt and the frame. Fig. 1 shows a cross section of a part of a machine for cooling a metal sheet equipped with the inventive device, Fig. 2 shows a section A-A in Fig. 1, The drawings show a part of a machine for rapidly or accelerated cooling a metal sheet of a conventional model. Such a machine has a closed space around the guides and pull rolls in which the cooling part circulates. This machine consists of two frames, the bottom 1 and the top 2, and the top frame can move in a vertical plane using devices not shown in the drawing. Each of these frames has on each side of the machine side walls 3,4 in which holes 5,6 are made in which guide rollers 7 and 8 are installed, surrounded by shells 9,10. A sealing gasket 11 is laid along the entire length of the machine, the lower surface of which is fixed on the upper plane of the lower frame, and the upper surface abuts the end of the side wall 4 of the upper frame. The neck 12 of the roll 8 rotates in the bearing 13, which in this example can be a bearing with a spherical bearing surface or another, and this bearing is mounted in the holder 14, which in turn is fixed in the suspension, which is a bracket 15 and two sidewalls 17, the ferrule 14, is installed between the sidewalls 17, locking the holders 18 fixed on the ends of the sidewalls of the bracket, and the intermediate block 19 is located between the casing and the inner surface of the bracket, the very same bracket 15 is located between the two sidewalls of 20 volts the swivel bracket 21 mounted on the protrusions 22, which are part of the upper frame, the first bracket 15, together with the upper plate 23, with which it is connected with a threaded pin 24 and nut 25, forms a movable assembly mounted inside the second bracket 21. To this end, the upper part 26 of the second bracket has a hole 27 through which the pin 24 and the sleeve 28, which serves as a gasket between the upper surface of the first bracket and the lower surface of the plate 23, pass; Moreover, between the upper surface of the first bracket and the lower surface of the second bracket, and between the upper surface of the second bracket and the bottom surface plate 23 are laid elastic pads 29, 30, these spacers may be represented l a single block or a set of Shai elastomer or any other elastic material stacked on one another. The dimensions of the sleeve 28 are chosen so as to determine the preliminary axial load acting on the gaskets 29.30. Lifting rings 31 can be installed on the upper plate 23 (FIG. 2 The sleeve 14 itself continues in the direction of the machine in the form of a ring 32, consisting of a radial flange 33, with which the ring is attached to the holder, and skirt 34, the axis of which coincides with the axis of the roll, and it is of such dimensions that limits some radial spacing with the neck of this roll not for processing the sheet contains two sealing gaskets 35 and 36, One of them 35 is located between the roll neck and the ring 32, has a classical design and ensures the tightness of the connection between two parts, rotates, imis relative to each other. On the other hand, A sealing gasket 36, having an X-shaped or similar form, is located between the outer surface of the ring 32 and the inner surface of the ring part 37 fixed on the plate 38 covering the opening 6 in the side wall of the machine. This plate 38, in turn, is fixed on the machine with the help of the tabs 39 and the block 40, and it is preferable to continue elastic gaskets between the plate and the machine. When mounting the lower rolls, taking into account the requirements of standardization, most of the elements similar to those used in the upper rolls, with the exception of elastic joints, are used, since the bearing cage rests on the fixed removable bracket 41. 42, driving rollers in motion, which are covered by shields 43. The device operates as follows. Due to the elastic attachment of the roll brackets, in which the elastic pads 29, 30 are pre-loaded in order to allow the movement in two directions, the upper rollers can withstand vertical displacements of the order of several millimeters, which may be caused by the deformation of the sheet or even an error in adjusting the position of the upper frame. Such a possibility of some movement in the vertical plane is absolutely necessary for good operation, reliability and service life of this machine. This device can also be used when mounting the lower rolls in order to increase the amount of movement in the vertical plane. The ability to move in a vertical plane, the presence of an intermediate ring 32 rigidly connected to the yoke and two sealing gaskets 35, 36, each of which operates under certain and different conditions, ensures excellent tightness as well as better safety of each of the gaskets. . Each gasket works in optimal conditions: one ensures tightness when parts rotate.
    and a friend, when moving them, since it would be very difficult and expensive to create one sealing device that would perform both of these functions.
    The invention has been described with reference to a machine for cooling or tempering of a particular type, but it can equally well be applied to other sheet metal processing machines.
