    In the stacking section 1, a horizontal platform 13 is provided between the pairwise arranged transport brackets 3, on which in the transverse median plane between the transport levers 3 at a distance from each other are fixed fixing pins 4 and 5. The horizontal platform 13 is fixed in its central part on the piston rod 14 drive 15.
    The cylinder of the piston device 15 is connected to the horizontal side of the curved bearing element 16, which is attached by welding to the base bearing element 17 of the device. The horizontal pad 13 is provided with a parallel piston rod 14 with a guide pin 18, which passes through the aperture of the horizontal side of the support member 16. The locking pins 4 and 5 are heated by a heater, the heating current to which is supplied via lines 19 and 20. Due to the actuation of the drive 15 the horizontal platform 13 is lowered so that the points of the stacking pins 4 and 5 are located below the transport plane of the transport tapes 10,
    In Fig. 2, it is seen that between endless transport belts 10 rotating parallel to each other there is a gap in which the horizontal platform 13 is raised and lowered from the horizontal with locking pins 4 and 5. Transport belts 10 are supported on box beams 21 and 22 s. smooth surface. In addition, the side portions of the stack 11 hang in lateral directions from the conveyor belts 10 (FIG. 2).
    In the separation section above and between the gap formed by the beams 21 and 22, two piston devices 23 and 24 are fixed on the fixed beam, the rods of which carry the heated separation knife 25, which can be lowered in the median longitudinal plane and interact with the rigidly-reinforced between beams 21 and 22 by a counter holder 26, the surface of which is on the same straight line as the transport plane.
    On the outer sides of the beams 21 and 22 in the separation section II they are strengthened with the possibility of swinging around mutually parallel, oriented
    From the transport direction, the stack of horizontal axes 27 and 28, supporting combs 29 and 30, which with the help of piston devices 31 (FIGS. 3 and 4) can be rotated into the transport plane and leaned towards beams 21 and 22.
    On the side walls 32 of the bed in the area of the separation section IT are installed with the possibility of rotation around the mutually parallel axes 33 and 34 oriented in the transport direction of the stub white axes 33 and roller roller 35 and 36, which can be rotated in a plane with the help of piston devices 37 (Fig. 5) transport and lean back to the side walls of the bed 32. The roller combs consist of a beam 38 on which freely rotating rollers 39 are fixed. The freely rotating rollers 39 of the roller combs and the teeth of the support combs 29 and 30 are arranged in such a way that they are in the gap and freely pass through each other. In the transport direction, successively behind roller combs 35 and 36 and support combs 29 and 30, additional transport tapes 40 and 41 (Fig. 7) are provided between the conveyor belts 10 and the side walls of the bed (skewing) located on the end side of the deflection rollers 9. Above are additional the conveyor belts 40 and 41 are provided with clamping elements 42 and 43 in the form of a belt or a tape, enveloping one deflecting and one guide rollers, the entrance gap of which is located in the area of the separating projection II and captures transported stack. The second embodiment of the stacking device (Figs. 8 and 9) includes a stacking section I and a separating section II in ce-1-b.
    The locking means of the separated stacks on the conveyor are infinite clamping straps 44 and 45 located above the conveyor belts 10. These clamping straps form for the stack 11 a two-sided roller 46 and 47 of the inlet gap directly behind the stacking section I, so that the stacks of bags are clamped on the conveyor belts 10 right up to the moment they are removed. On the lower clamping branches clamping rem0

    44 and 45 are affected by spring-loaded pressure rollers 47. The rear deflecting rollers 48 of the clamping belts 44 and 45 are strengthened to swing in the rocker arms 49, which can be raised and lowered using piston devices 50. When using devices, there is no need for special clamping or lifting means for the separation section, since in it the stack of packages is fixed (Figures 8 and 9).
    The exemplary embodiment of the device according to FIGS. 3 and 9 is substantially simplified / since in order to ensure the position of the stack 11, both immediately after stacking and during separation and alternate removal, it is necessary to provide only one pair of clamping straps 44 and 45, which interact with the effect of clamping with the transport branches of the transport tapes 10.
    It is also possible to refuse positioning holes provided in the central region of flat objects or double bags. Instead, in this case, the stacking pins are also made as heated needles, on which objects are strung. The stacking pins preferably consist of heated needles, on which objects are strung without prior perforation.
    The device works as follows.
    In the separation section II, in order to lift the side parts of the stack 11 of the bags hanging down, first, using the piston devices 31, the support combs 29 and 30 are rotated into the transport plane so that the stacks 11 are oriented in the transport plane. After the support comb is rotated, the side roller combs 35 and 36 are rotated, so that the support combs 29 and 30 can then be folded backwards (Fig. 6). After dividing the double stack into separate stacks, the latter are clamped between the side support strips 40 and 41 and the upper clamping elements 42 and 43 (Fig. 7). Folding support combs 29 and 30 and roller combs 35 and 36 allow during the transportation of the stack divided in the middle part to introduce the next stack into the separation section II. For this purpose, after the roller comb is raised to the position between the teeth of the support comb, the support ridges are lowered to the beams 21 and 22. There is a gap between the ends of the raised rollers of the roller comb and the support combs folded down (or beams 21, 22) that is greater than the height the stack to be separated, i.e. the piles can be inserted into this gap with their downward hanging sides and move freely to the separation section II, since the gaps between the ends of the raised rollers of the roller comb and the folded support combs are quite wide. If the pre-stack is retracted, the roller comb 35 and 36 are also folded back, so that as a result of removing the support comb, the side portions of the roller comb 35 and 36. Thereafter, the roller comb is retracted so that after cutting, individual stacks can be withdrawn.
    Folding and retractable roller and support combs, therefore, allow, in turn, to raise stacks 11 that follow each other closely to the separation section II into their horizontal position, to separate and retract them.
    After a predetermined number of double bags are mounted on the fixing pins 4 and 5 with the help of the support arms 3, the supply of the bags is stopped for a short time. The rack pan 13 with the locking pins 4 and 5 is lowered, as a result of which the piles 11 freely lie with the side portions hanging downwards on the conveyor belt 10. As the locking pins 4 and 5 are heated, the piles are already interconnected in the area of the stacking holes. After lowering, the stacking pins are carried out
