The circular plate 32 is supported on rollers 34 having grooves, and on the plate there is a spur gear 35 rotating from the engine 36, the rollers being attached to the lower carriage 17. Therefore, the motor 36 is intended to rotate the laying head 18. around the Z axis. to the beam 16, the lower carriage 17 rests on the brackets 37 associated with the upper carriage 1, and the worm shafts 38 and nuts 39 on the shafts 38 are rotated by the engines 40, moving the laying head in the Z direction and applying in the Z direction to the head 18 a force oppose force that occurs when laying the tape on the laying tool 15. Means 2 for feeding the material. 3 can also be rotated around the Z axis by an angle of 0. This means is mounted on a plate 41 having a circular through hole 42. A hollow cylindrical element 43 is connected to. the plate 41 around the hole 42 and has a plate 44 for fastening. The plate 44 rests on rollers with grooves 43, which, in turn, are mounted on the upper carriage 1. On the element 43, there is an annular gear 46 fixed on its lower edge. The gear 46 is rotated by the engine 47 through the gear of the gearbox 48 and the pinion gear 49. Thus, the plate 41 and the means 2 for feeding the material 3 around the Z axis are driven by the motor 47. In the laying head 18 there is a primary roller 30 as well as a secondary roller 51 through which the ribbon of material 3 passes when the laying tool 15 is laid on the surface when the primary roller 50 rolls along the surface of the laying tool 15. The secondary roller 51 is driven by a gear drive (not shown) with the primary role com 50. The tape is held along the roller guide 52 by the rollers 53 and 54, which are connected to the primary roller 50 of the chain drive 55, where paper packaging 56 is removed during the passage between the rollers 53 and 54, then the tape passes through the roller 57 and is wound on a bobbin 58, which is rotated by a motor 59 with a sliding sleeve, the rollers 53 and 54 facilitating the downward pull of the tape, pulling the paper packaging 56. There is a tape cutter that is driven by the solenoid 60. The cutter is designed for cutting the tape. in need. The tape, together with the packaging, is wound on a reel 61, passes over the roller 62, between the rollers 63 and 64, a roller 65, which is attached to the oscillating lever 66, is directed upwards along the roller 67 and down into the guide 52, which is attached with its the lower end to the lower carriage 17 of the guide support 68. The reel 61 is fixed; on the stand 69, and the rollers 62, 63, 65, 67 and the oscillating unit 66 are fixed on the structure 70, the structure 70 and the stand 69 being mounted on the plate 41. Kronschtein 71, attached to the structure 70, retains, with the possibility of movement, the guide 52, Thanks to this, it can move in the Z direction with any movement in the Z direction of the lower carriage 17. During operation, when the tape is pressed down through the guide 52 by the primary roller 50, the oscillating lever 66 is attracted upwards to the rollers 64 and. 67. When the oscillating lever 66 reaches a predetermined height, it is in contact with the microswitch 71 installed on the structure 70, turns on the motor 72, which rotates the roller 64, while the tape is unrolled from the reel 61. As the tape is unrolled from the reel 61 more than being pulled by the primary roller 50, the oscillating lever 66 falls down to contact with the microswitch 73 mounted on a bracket 74 which turns the engine 72, the driving roller 64 off. In the end, the oscillating lever 66 moves upwards m tension primary roller 50 on the tape. In such an operation, the belt is under constant tension even when the primary roller 50 is stopped or put into operation. In the control system there are sensors 75 for controlling the supply voltage to the motors 11 and 6, whereby the upper carriage I can move interconnected with the roll bottom carriage 17. Sensor 75 contains cylinder 76 attached to beam 77 and rod 78 inserted into cylinder 76 and attached by element 79 to beam 8 on which top carriage 1 is mounted. At any movement of bottom carriage I7 in direction X, the upper carriage 1 is not accompanied by a similar movement, the cylinder 76 and the rod 77 move reciprocally, the output signal is generated and the engine 11 is turned on. The cylinder 80 is attached to the winding 23 of the engine 25, the rod 81 is attached to the winding 23 of the engine 25, and the rod 81 is inserted into the cylinder 80 and is pressed against the element 82 attached to the upper carriage 1. Any movement of the lower carriage 17 in the direction U, which is not accompanied by a similar movement of the upper carriage 1, causes a relative movement the cylinder 80 and the rod 81, while the output signal is developed and the engine 6 is turned on. The control system 83 may include an additional engine 84. During operation, power is supplied to the engines 6, 11, 25 and 30 to move the upper 1 and lower 17 carriage, the means 2 for feeding the material 3, as well as the laying head 18, are brought into a position in which the tape is to be laid on the laying tool 15. As soon as the laying head 18 comes to a predetermined position, the motor 36 and 47 turn on simultaneously ota ukladshayuschey head 18 and supply means 2 material 3 in a predetermined direction. The gears of motors 36 and 47 are designed so that the rotation of the plate 41, on which the means for feeding material S1 is installed, is synchronized with the rotation of the plate, 32 on which the stacking head 18 is mounted. Then the stacking head 18 lowers to the surface of the stacking tool 15 by switching on the motors 40, wherein a predetermined force is applied in the direction L to press the tape against the surface of the laying tool 15. By means of the control system 83, these engines are included, as well as the engines 72i and 59, thanks to Because the tape can be laid on the surface of the laying tool 15. The nuts 39 of the screw drive are freely mounted in the bottom carriage 17, whereby the top carriage 1 interconnects with the bottom carriage 17, cannot follow: go behind the bottom carriage 17 with the same degree of accuracy which is required to move the lower carriage 17, ensuring that the tape is accurately laid using the stacking head 18. The height of the stacking head 18 in the Z direction is adjustable, thus the tape can be stacked in several layers and also adjusts ate pressing in the Z direction for tog; so that the layer of the snooty flow proceeds properly when the tape intersects itself when it is carried out - non-slip passes in the manufacture of mesh structures. If low pressure is required or pressure is not required at all in the Z direction, the drive system in the Z direction can be replaced by engines 84 and 85 (figure 5, thin lines), which can drive the drive shaft, as well as the screw drive nut. Thus, this device is intended for laying material in which the heavy and volumetric material supply system is disconnected from. stacking head.
