    In the manufacture of packing containers by external processing, sealing and cutting of tubular packing material the tube contents are made use of as a hold-on in the shaping work. To prevent the eclosed quantity of air from being pressed out in this process through the upper open end of the tube a sealing unit (14) present in the tube is used which comprises a movable sealing holder (18) which in accordance with the invention is pressed by means of the pressure of the enclosed quantity of air in a balanced manner so as to form a seal against a sealing surface (22). On the periphery of the sealing holder a sealing (24) of flexible material is provided which is resting aginst the inside of the material tube.

    The invention relates to a device for packaging products in bags of layered material and can be used in various industries.
    The purpose of the invention is improving the quality of packaging.
    In Fig.1 shows a device for the manufacture, filling of the product and zagrechivaniya bags of Christmas packaging, material, general view; figure 2 - sealing device, enlarged.
    | The device contains a roll holder • | spruce 1 for packing laminate 2, guide rollers 3 and 4, and a bending roller 5. The sleeve-likeTenb includes bending 6 and forming 7 elements. The device for the formation of a longitudinal seam with which the web of the packaging Opoic material 2 is transformed into a tube 8 is a nozzle 9 for supplying hot air. The device for the formation of transverse ΪΒΟΒ, dividing the tube 8 of the casing material 2 into Bags 10, includes grips 11 and 12 mounted with the possibility of reciprocating vertical movement.
    The device also contains a supply pipe 13 and a nozzle 14 for supplying fas a. Between the supply pipe 13 and the Tube 8 of the packaging material 2 above the device for the formation of transverse seams is a sealing device. It includes mounted on the supply pipe 13: A sleeve 15, consisting of two parts 16 and 17, placed between the last washer 18, having an annular protrusion 19 at the upper end and a ring 20 covering the washer 18, and resting on the inner surface of the tube 8 from the packaging material 2. The washer 18 has a central stepped hole 21. In the upper part of the sleeve 15 a channel 22 is made, communicated with the hole 21 of the washer 18 and the gas supply pipe 14,
    The washer 18 has, for example, a stepped shape, and the diameter of the lower part of the ring 20 exceeds the diameter of its upper part.
    The device operates as follows.
    The packaging laminate 2, being wound off the roll holder, passes upward through the guide rollers 3 and 4. When the packaging material 2 passes the bending roller 5, it begins to move vertically downward. Using bending 6 and forming 7 elements and a nozzle 9 for supplying hot air, the packaging material 2 is converted into a tube 8.
    After filing through the supply pipe 13 to the ’tube 8 of the packaging material 2 of the product, the formation of transverse seams. The grippers 11 and 12 continuously move back and forth in the direction to each other and from each other to compress and close the tube 8 of the packaging material 2, forming packages 10. Moreover, the grippers 11 and 12 alternately weld the tube 8 of the packaging material 2 and pull it. The resulting bags 10 are separated from the tube 8 of the packaging material 2 and sent using a conveyor (not shown) for further processing.
    In the formation of the bags 10, the air or gas contained in the tube 8 of the packaging material 2 must be enclosed accordingly, because otherwise the back pressure, which is necessary for a satisfactory molding process, is not achieved.
    To provide the necessary back pressure, a sealing device is used.
    The backpressure gaseous medium is introduced through the nozzle 14, passes through the channel 22 in the upper part of the sleeve 15 and the central step hole 21 of the washer 18 into the tube 8 of the packaging material 2. In this case, the backpressure gaseous medium acts on the sealing device so that the protrusion 19 of the washer 18 is pressed against the upper part 16 of the sleeve 15 despite the weight of the washer 18 and the downward force acting on the washer 18, since the ring 20 rests on the inner surface of the tube 8 of packaging material 2, which moves etsya down. The width of the annular protrusion 19 of the washer 18 is set such that the difference between its surface area and the surface area of the washer 18 gives the required upward force, exceeding the downward force due to the movement of the tube 8 of the packaging material 2 and the washer 18.
    Satisfactory leakage safety will be ensured by the contact pressure of the annular protrusion 19 of the washer 18 with the washer 18 itself of approximately 0.5 bar (the ratio of the areas of the annular protrusion 19 and the washer 18 is 1: 4). Due to this design, the contacting force of the annular protrusion 19 with the washer 18 can be precisely determined and selected in such a way that the required degree of impermeability is achieved; whereas at the same time 15, the washer 18 remains sufficiently movable in the radial Direction to provide good compaction despite relative movements in the radial direction between the 20 DU tube 8 of the packaging material 2 and the feed tube 13. By selecting the lowest possible contact pressure the washer 18 can easily move laterally, which 25 means that the ability of the ring 20 to move can be large, so that the sealing effect is optimized while the wear caused by contact with movable packing material 2 is reduced. Since the requirements for the elastic material of the ring 20 are reduced, it becomes possible when choosing the material to pay more attention to the resistance of the ring 20 to wear, which improves the operation of the sealing device as a whole, helping to improve the quality of packaging.
