    A machine for packaging in a vacuum or in a controlled atmosphere has bells (1-24) and covers (I-X) that are continuously fixed to two separate annular conveyors (25, 26) that move on two separate horizontal superimposed planes. The lower conveyor is longer and is provided with a plurality of equally-spaced bells, the fixing plane being turned upwards, whereas the upper conveyor is shorter and provided with fewer equally-spaced covers, having the same spacing as the bells, with their fixing plane turned downwards. Both conveyors cross at least one geometrically identical section, in which in a stationary state of kinematic equality a perfect matching by superimposition of the fixing plane of each cover and of the fixing plane of the corresponding bell is achieved. Upstream and downstream of the section in which there is a state of kinematic equality between both conveyors, the bells are always open at their tops, in order to allow technological preparation and finishing processes to be carried out in each bag that constantly remains in the said bell.

    substances, a kets filling sensor 70, a device 71 for forming lateral folds on bags, a cutting device 72, a device 73 for final unfolding of the package head, an adhesive tongue 74 for strengthening the fold or fold on the head of the package, a device 75 for dredging the package it on the discharge conveyor, mounted on the seat of the mandrel 76 to shape the packages, a roll 77 of flexible material in the form of a film, a fixed cam 78 or a guide for the vertical movement of the removal device 79, intended for stacking bags from mandrels and feeding them into the glasses passing below, rod 80 for placing the film cut by cutting device 81 on the mandrel, device 82 for making and filling bags before putting them into glasses and transfer belt packages manufactured at the appropriate node (not sold) „
    According to Fig. 1, in all twenty-four glasses 3 26, the sealing or sealing surface is directed upwards, while for all covers 61, the sealing surface is directed downwards. In addition, both conveyors 1 and 2 pass at least one segment which is geometrically identical at the top and bottom and in which, at an unchanged kinematic state, an exact match is provided between the sealing surfaces of the lids and the sealing surfaces of the glasses. Along the entire area, in which the conveyors 1 and 2 are pumped in a state of kinematic unity, it is guaranteed that the covers 52 56 in each case will be superimposed on the cups 13 to 17 so as to ensure their tight closure. which allows it to evacuate the air and, if necessary, replace it with an inert gas before printing the bags without access

    Replacing it with an inert gas is provided by appropriate means using known vacuum tubes that connect ten caps through a rotating distributor 62 to a vacuum circuit 64 activated by a pump 63 shown schematically with a vacuum gauge, the dial of the dial shows the remaining residual vacuum. Air bags for sealing bags inside cups protected in this way from the outside atmosphere are not shown, as they are known in the technique of thermoplastic svagrirovaniya
    The supply of the required energy is passed through a rotating distributor -66, which transmits pulses of energy to a clamp for sealing, which it receives from the generator 65 o. The clamps for sealing (not shown) are inside two twenty-five lids connected to the conveyor. - 61.
    The supply of the corresponding covers is effected due to the fact that the trajectories of both conveyors 1 and 2 pass in such a way that kinematic unity is ensured along the section on which npofH- upper and lower hours are - these are geometrically similar and move synchronously. At the same time, only in this area an exact coincidence occurs by overlaying the covers 52: - 56 on the corresponding glasses 13-17 (FIG. 1). On the contrary, opening the glasses, m, e, separating the corresponding covers from them, passing - goes by successively separating the paths of the conveyors 1 and 2, with the glasses always open upwards in front of and behind the kinematic uniform section. In addition, bag 27 is fed to beaker 3 just as bag 28 was previously fed to beaker 4, and as previous bags were fed to previously served cups.
    Along this entire part of the trajectory, in front of the said section, bag 20 is loaded with product, for example, through a hopper of pre-expansion device 67. Similarly, bag 31, which was fed or loaded into cup 7, seals the product by means of device 68 for compaction. Under the channels 6 and 7 there is a vibration device 69, which provides

    The optimum shrinkage of the product inside the packages 31 and 30 is determined. Next, the level of the packed product loaded in the package 32 is determined by means of a special sensor 70,
    On package 33, device 71 provides for the execution of lateral folds. In package 34, a cutting device 72
    0 cuts off a part of the material after running out of the side folds. All these works performed before the said section, in accordance with the technological requirements of the packaging process.
    5 may be of a different nature.
    According to FIG. 1, the already sealed bag 44 folds the upper part of the package (indicated by a curved arrow on the top of the package)
     On the package 45, which is pushed into the glass 21, the plate of the device 72 pro is making alignment of the upper part adjacent to the package body, so that it acquires a battle form. On the package 46, the device applies an adhesive tongue 74 at a temp to attach the flat upper part the end of the square pack

    When moving down the bag 27 from the mandrel, the fixture 19 pulls it into the container connected to the transport with 1 cup 3 The mandrel from which the bag 27 was removed, thus the "5" is free to receive the film " which the rod 80 pulls down before cutting it with a cutting device 81, the cue material used to make the bags is unwound from the roll 77.
    In Fig. 1, the positions of 86 g-90 show the areas into which the film web is subsequently cut and the 5 Pbie film is wrapped around the mandrels so as to give them the shape of bags; schematically also shows the steps of twisting the sections 91 94 of the film around the mandrel of the crosspiece 76,
    Fig. 2 shows how, after ten steps of supply after cutting off the section 85 of the film, this section has already been advanced ten steps forward and in the wig of the bag is already filled, vibrated and compacted and placed in the corresponding cup 22. which also checks the filling level. Cutting pieces of the film to be cut are indicated by the positions 95-100 and they are unscrewed from the roll 77. Cutting of the film, screwed around the cross-head 76, are indicated by the position 101 "104o. In Fig. denoted by the positions 105 - 110, and emy on krestos guilt piece "- 111 In all three Góry in the same glasses vkpaDg- vayuts same packets and they start their working cycle to izvleches- nor remain in the form of square chum
    In the glasses, from which the packages were removed, for example, 23-26, other packages were subsequently put
    In Fig. 2, it can be seen that the cups 23 "26, which in Fig. 01 were empty, are stacked to ensure a stable, stable position of the packages formed from the sections 91 94 of the film with
    Figs 1, 2 and 3 clarify the sequence of the technological process in which the bags are never removed from their glasses.
    This circumstance shows a high degree of reliability of the machine, especially when the packages are made of very cheap flexible material that does not carry very well with various operations at high speed, as required by the increased
