The drive of the carriage 21 contains a parallel longitudinal rod parallel to the belt surface transport 5, having ends 23 and 24 and attached to opposite flanges 25 and 26 of similar elements, in turn connected to support 6. Rod 22 passes through hole 27 of carriage 21, which is connected by means of pulling 28 (Fig. 1), 1 parallel to the rod 22, with the means 19. The means 19 is intended for wadding the belt, followed by securing the belt 21, movement of the carriage 21 along the rod 22 and pulling the second end of the belt, already raised with a relatively flat support structure 16 in the correct position without any mechanical damage. The clamping means 18 are provided with two parallel planes 29 and 30, one of which 29 is parallel to the conveyor belt 5 and connected to an actuator 31 mounted on the carriage 21 by means of articulated levers 32 and 33, one of them connected to the rod and 3 the power drive 31, and the other ends of the hinge connected to the plane 29. On the supporting structure 16 a group of additional permanent magnets 35 is mounted. The tool 19 is made in the form of jaws 36 and 37. Each drive of the axial movement of the carriage 21 is made in the form of a power cylinder 38, with mounted on support 6, the rod 39 of which is connected with the carriage 21. The conveyor belt 5 with the corresponding pulleys 7 and 9 is installed on the V-shaped structure 40 (Fig. 2), passing along the support 6 fi connected with it a series of fcanec 41s directed perpendicularly to one another to provide a direction for the V-shaped structure 40 along the respective guides 42, the movement of the V-shaped structure 40 and the associated band being due to the fact that the means of displacement are are a hydrodynamic mechanism 43, which is coupled at its end to the support rod 44 6, and the actuator 15 is connected to the structure 40 (Fig. one). The cutting mechanism 11 contains a hydrodynamic mechanism, the cylinder 45 of which is attached to the beam 46 of the support 6, the rod 47 of which is orthogonal to the flat supporting structure 16. The mechanism has two cylinders 48 and 49, the rods 50 and 51 of which are connected: with two cutting blades 52 and 53 moving in a horizontal plane. The cylinder 45 is actuated to allow two knives 5 2 and 53 to be placed in the center of the space between the two metal cords of the breaker to cut it, and the cylinders 48 and 49 are driven to move one from the other two knives 52 and 53 in the direction of the cords breaker to form one end. In a preferred embodiment, the device 12 (Figure 1) for aligning the two ends of each belt section on the conveyor belt 5. The transmission mechanism 12 provided for each belt layer can control the movement, transport and overlapping of the narrowest sections of the belt layer, which are the most deformable with respect to the fixed surface of the flat supporting structure 16 on the upper surface of the conveyor belt 5 during movement. The transmission mechanism 12 may be made in the form of metal fingers or shear layers of levers that capture the opposite parts of the belt layer, or be appropriate gripping means with adhesive characteristics with respect to this belt layer. The plane 30 is connected with the stem 54 of the power cylinder 55 mounted on the support 6. On the plane 29 permanent magnets 56 are mounted. The carriage 21 includes an extension 57 equipped with a small wheel 58 for sliding along the guide 59. Sponges 36 and 37 of the means 19 with actuated by a pneumatic control lever 60, the stem 61 of which, acting only on one sponge to overcome the resistance of the provided spring (not shown), ensures the closure of the means 19 of the gripping device. The power cylinder 38 is located parallel to the rod 22 and is connected at one end 62 by a support 6 in the direction of pushing the stem 39 B to the opening 6 of the flange 25 to the surface of the carriage 21 to ensure that it moves from the conveyor belt 5 towards the cutting mechanism 11, since the lips of the lips are above the support structure 16 and against the blade direction. The positioner 64 comprises a pin 65 connected, for example, by a lever rotating on the hinge 66 of the support 6. The lever 65 moves the pin 65 from the rest position into contact with the surface of the carriage 21 for yc .taHOBki sponges in the raised position relative to the support structure 16 and in the direction of the cutting line breaker (Fig. 1). The device also includes means 67 located between the drum 8 and the support 6, which are designed to remove the belt layers from the conveyor belt 5 and to gradually wind the rotating babaran 8, which rotates in the opposite direction relative to the movement of the belt. These tools include a lever pivotally mounted on shaft 68 of pulley 7 (Fig. 1), a pointed element 69 connected to the end of lever 70, a cylinder 71, the rod of which pushes element 69 on the conveyor belt 5, if necessary, and under the breaker layer in in the direction opposite to the direction of movement of the flat support structure 16, it is easier at the point of contact and pressure between the flat support structure 16 and the drum 8 (Fig. 13) to separate the belt layer and wind it onto the drum 8. In addition, the device has a stop 72, The device works as follows. in a way. The planes 29 and 16 (Fig. 7) are in idle connection with the means 19, i.e. with the jaws 36 and 37 open. Subsequently, the planar support structure 16 is demagnetized and the power cylinder 55 is actuated so that the rod 54 (Fig. B) raises the plane 29 and with it the end B of the layer. At the same time, the rod 39 moves again inside the cylinder 38. A rigid connection between the planes 29 and 30 and the conveyor belt 5 is provided by the control lever 60 so that the jaws 36 and 37 approach each other, on opposite edges of the belt. In addition to these operations, planes 29 and 16 transport the end B of layer B from the position shown by dotted lines in FIG. 8, to the position shown by the solid line in the same drawing, immediately above area G, 1 in which the first group of magnets operates during continuous motion I. Immediately after this, the conveyor belt 5 stops and the cylinder 55 is actuated like this (Fig. 6), that rod 54 exposes again plane 29 and along with it end B of layer B on conveyor belt 5. At this point, actuators 31 are driven sequentially to first turn first lever 32, and then another than causing inclination of plane 29 relative to the surface of the strip forblegcheni separating the magnets from the belt with the exception upward pull on the end B, hogda rod 54 is pulled back chnutr corresponding cylinder. After this operation, the end B is pulled off by magnets on the surface of the strip and retains the specified alignment, since the grippers have moved along the rod 22 (Fig. 4) on the side of the tape without displacing the axis from the ORIGINAL position (Fig. 7). Thereafter, planes 29 and 16 are adjusted to trap and align the second end of the layer on the strip. The steering control assembly 60 is first operated so that the jaws 36 and 37 (Fig. 2) no longer capture the belt, and then the engine 10
    (Fig. 1) to move forward the conveyor belt 5, at the same time, the claws in the direction towards the plane 16 about the docking of the surface of the carriage 21 s (Fig. 1) are immediately brought into contact with the pin 65 of the positioner 64 rotating around the hinge 66.
    It is the most guaranteed to obtain the conditions (. 9) in which. the tape stops when the end of the tO B layer is under element D (photocell, etc.), and the plane 29 comes into contact with layer B above it along the cutting means to keep this layer blocked by ts and ensure the formation of the second one. end E of the breaker by means of cylinders 45 and 49, which provide lowering and relative separation of the knives 52 and 53 moving blunt 20 with two adjacent layers of the breaker, and the power drives 31 act at the same time to introduce the magnets 35 (figo 6) into the position of a magnetic attraction layer breaker J. 25
    In this position, the grippers are brought into action in the case of the initial end B of the breaker, and after inserting the appropriate means 19 with the conveyor belt 5 into motion, the end B connected to the plane 29 and the supporting plate 17 is inserted over the magnets , (FIG. -11), after which the said end E is applied to the belt, which is still held by the stop of the gearbox of the engine 10.
    Following this operation (Fig. 1), the breaker layer B is completely located on the conveyor belt 5. A distance of 40 is produced by the slightest movement of the strip (Fig. 12) until the end of the breaker layer located at position 3 of the pulley 7 is not included in contact with
    drum 8, and at this time the gripping-blind of the tape operates, further controlled by photocell D or a similar element fixing the presence of the end E of the belt layer.
    At the same time, the grippers separated from the tape when opening the jaws are transferred to their initial position at the beginning of the cycle, namely (Fig. 12) in the direction opposite to the cutting means, ensuring that the new end and layer are received as it gradually gets reels 2.
    The following procedure describes how to transfer the belt layer.
    .B-E on the drum 8.
    First, the hydrodynamic mechanism 43 is activated by extending the stem 44 so that the V-shaped structure 40 (Fig. 1 and 2) can slide relative to the support 6 as the layer contacts the drum 8 (Fig. 13).
    Then the drum 8 is rotated in a certain direction opposite to the rotation of the pulley 7, and the cylinder 71 (Fig. 1) is actuated to move element 69. (Fig. 14) into position to facilitate separation of the layer along its entire length from the conveyor belt 5 and its winding on the drum 8, provided in turn with magnetic inserts to better hold the entire layer on the surface.
    At the end of the cycle, the first layer of the belt is wound on the drum 8. Similarly, the second layer of the belt is fed from the second reel towards the second belt and, therefore, on the drum 8 around the first layer of belt. Then the cycle repeats.
