    .Q., Treating a stack of blanks 2 bags that are compactly placed on the base (or main) plate 8. A 3 stack of blanks 2 bags found in the store is constantly compressed with some specific force opposite to or in relation to the pusher 10, which in this case, it performs the function of an outlet device at the outlet end of store 3 to ensure that a position where at any time one blank 2 of the packaging bag is always ready at the outlet or exit end of store 3 for its subsequent transfer to trans 4. A similar effect Orter preforms SP2 on the outlet or discharge end of the store 3 is not shown in the drawings, but may be carried out by known conventional devices, for example via the presser plate, which affects weight or a spring force on the back of the store 3 drugrm.
    In the upper part, the pusher 10 has a protrusion 11. 2 packages arranged parallel to the horizontal blanks, and the height of the protrusion I mainly corresponds to or slightly less than the thickness of the flattened billet 2 packages. The pusher 10 is connected in its lower part with a driving rod 12, which is driven by a motor (not shown), and in its upper part is connected with two levers 13, which are interconnected by a hinge 14. Each lever 13 with a free end is fixed on the axis 15, whose length is equal to or slightly greater than the length of the workpiece 2 package. Axes 15 are placed in divergent curvilinear guide grooves 16, symmetrically formed in plates 17. Levers 13 have channels 18 that are connected through common pipes 19 to a common or each to their own vacuum source (not shown) to suck to opposite sides of the workpiece 2 package.
    In accordance with the invention, it is very important that the channels 18 of the levers 13 are connected to a vacuum source in such a way that they can be controlled individually, i.e. independently of each other.
    Pusher 10 via stem 12
    can perform reciprocating "(there is located or stacked vertical movement in the interval-stack (horizontal), which
    Le between the lower and upper positions. This particular example means
    When in its lower position, the protrusion 11 of the pusher 10 is something of the right of the bend line 20 is turned face down, and the left line of the bend 21
    mediocre under the lower edge of the fore 20 ba - face up. Can be allowed
    Package 2, which lies at the very top of magazine 3, whereas when the pusher 10 is in its top position, the protrusion 11 is on one line or slightly above the top edge of the remaining blanks 2 packages. In the lower position, which is briefly defined above, the axis 15 is in such a position that the channels 18 of the levers 13 are exactly opposite to each other, while in the upper position the channels 18 of the levers 13 are mainly in the horizontal upward facing position, moreover, this is due to the fact that the axis 15 moves upwards and moves away from each other as they move along curvilinear grooves 16 made in the guide plates 17.
    The blank 2 of the packaging bag may be made of an elastic, but stable or shape-stable laminate, for example of a packaging laminate, which consists of a layer or layers of paper or plastic. After cutting the laminate into parts of the desired outer contour and first applying bending lines to them, which facilitate subsequent bending
    four-
    parts of the workpieces 2, seal and seal the two longitudinal edges between themselves so that this laminate forms a tubular workpiece 2 of the packaging bag. After that, flatten the blank 2 of the packaging bag by folding it along two longitudinal bending lines 20 and 21, whereby the blank 2 acquires

    shown in FIG. 6, the flattened i tubular shape, with the lateral sides of the A – D billet 2 clearly demarcated by the curvature lines, which are arranged in pairs opposite each other, so that, as shown in FIG. 6, the sides A and D, which are adjacent on the right side on the longitudinal line 20 of the bend, and the sides C and D, which are adjacent on the left side along the longitudinal line 21 of the bend, are exactly opposite each other. After this, a batch of flattened blanks 2 patches of the right of the bend line 20 is turned face down, and the left line of the bend 21
    that the arrangement of the blanks 2 in the store 3, which is shown in FIG. 2-5 assumes that the side of the blanks 2 of the packaging bags facing the outlet section of the store 3 is formed by the sides A and D, the side A being in the bottom or bottom position, and the sides P and C are rotated in the other direction, and side B is in the bottom or bottom position.
    The device works as follows.
    When the drive rod 12 and the pusher 10, located at the outlet section of the magazine 3, are moved upwards, the protrusion 1 1 lifts one billet 2 of the bag.
    In the process of forced upward movement of the pusher 10 and the levers 13 associated with it, the axes 15 are controlled to move along the curved grooves 16 of the plates 17 in an upward direction towards the path, curved so that the grooves 16 move in opposite directions (see FIG. 2). In the course of this movement, the package blank 2 undergoes a lifting or transfold operation, during which the suction channels 18 of the levers 13, which act on the sides A and P of the blank 2, respectively, separate the sides of the blank 2 from each other as a result of folding these parts in any outward from each other along the bend line 20 so that ultimately they are predominantly in line with each other. This means that
    in turn, it means that the billet 2 of the package is at the same time the two upper sides G and D of the billets are subjected to the corresponding palletizing operation, during which two bending lines 20 and 21 are connected in series and the passage т to the intermediate position, in which the pre-flattened billet 2 of the package acquires a shape with a square cross section, i
    After reaching the top position of the axles 15 (see FIG. 4), the connection of the channels 18 of the levers 13 with the vacuum source is stopped, which means that the channels 18 no longer stick to the side P of the workpiece 2, and this
    The natural year, which is naturally inherent in it, tends to re-fold or bend, say, to restore its original flattened shape. During this re-folding or bending stage, sharpening 2 bags re-acquires a previously interlaced intermediate state with a square cross-section. By synchronizing the above-mentioned movement of the conveyor 4, located above the magazine 3, so that the holder 7 during the next advancement of the conveyor 4. needs to be in the correct position relative to the re-bent blank 2, so that it hits the bend line 20 of the blank 2 with each movement already after the blank 2 of the package has taken the form with a square cross section, it is possible to capture the blank of the 2 package in a raised intermediate position in the space between said holder 7 and by the charger 7, which follows immediately after it (namely

    this moment is shown in FIG. four). After that, the connection between the channels 18 of the TOR levers and the vacuum source is also disconnected, as a result of which the grip on the side A of the blank 2 of the bag is released and the supply and advancement of the blank of the packet 2 in a raised and square cross-section becomes possible along the conveyor belt 6 . After the vacuum connection has been disconnected, the axles 15 and the levers 13 together with the pusher 10 and the driving rod 12 are lowered (see sketch 2) and return to their lower position to wait for the next running cycles, i.e. to carry out a new operation to lift the following blanks 2 packages.
