    After completion of the flower formation process, they are pulled out of the last one upwards and moved to the initial position. Due to the decoupling of the block of the power cylinder 42, the folding of the rods is moved from one position to another (Fig. 3). By the action of the power cylinder unit 47, the folding rods are lowered and raised. After opting for the rods, the power cylinder unit 42 acts and the cylinders 4-10 are moved to a position where the neck of the bag is folded into a flower shape. The folding rods 4-10 may be positioned relative to each other somewhat obliquely so that the flower will be wider at the bottom than at the top, and this leads to the equalization of the difference in thickness caused by perefaltseniem edge of the neck of the bag. As a result of folding the edges of the neck in the form of a flower, the grippers 1 are released and return to their original position. In the process of packing, the proximal plates 21 are superimposed on the folding rods 9, 10, and the presser pads 20 press the ends of the sealing tape 57 protruding above the edges of the seam of the bag 2. Next, the electrodes 3 approach each other and the ends of the strips come together and the force shields 21 and pads 20 increases due to the action of the pin 22, 23. After switching on and turning off the welding current, the power cylinder block 31 returns to its initial position so that the electrodes 3 open and the levers 11 turn approximately on relative to their positions at svar ke. Due to this, welded ice can be cooled. The sealing tape is still held by the flaps 21 and the pads 20 in the position shown in FIG. 3, the weld seam is not yet loaded. After holding in this position for some time, the power cylinder unit 29 acts on the levers 11 and they turn at an angle approximately one relative to the other so that the shields 21 and pads 20 are lifted from the lever 11 through stops, acting on after. To raise the folding rods 4, 5, 6, and 9, 10, after completing the flower formation process and welding the ends of the tape, the supports 34 and 35 move a certain distance in the horizontal direction from their working position. For this purpose, lever 37 at position 56 is associated with cam 49, which can be blocked with lever 52 and roller 50 after completion of flower formation. The lever 52 moves to the locking position by the power cylinder 53. After turning the lever 52 to position 57, the power cylinder unit 53 acts, and the rod can only be moved to such a distance until the cam 49 contacts the roller 50. In this position, the folding rods 4 - 10 without pressure, they are pulled out of the flower upwards and then returned to their original position. Then the cycle repeats. Claim 1.
