    The invention relates to tire industry and can be used in assembling pokrysh on an assembly drum when applying layers of carcass, tread, etc.
    The purpose of the invention is to automate the process while ensuring high quality.
    FIG. Figure 1 shows the feed layers on an assembly drum tape; in fig. 2 — Layer applier.
    The method of applying individual layers is carried out as follows.
    Initially, individual layers 1 are measured at different lengths, corresponding to the circumference of the assembly drum 2. The layers are cut to a length of 1 that does not exceed the given length. Before overlapping, the actual length of layer 1 is determined and entered into the computing device, where it is compared with the circumference of drum 2, i.e. monitor the compliance of the length of 1 layers 1 with the circumference of the drum. Layers 1 are fed to the assembly drum 2 by means of a feeding tape 3 with an individual drive. Assembly drum 2 also has an individual drive. Both drives are controlled, while the circumferential velocities of the driving circle correspond to the ratio between the actual and specified values of the length of layer 1. When monitoring the compliance of length 1 layer 1 with the circumference of drum 2, there may be a deviation of length 1 of layer 1 from the circumference of drum 2. In this case, the assembly drum 2 n. begin to rotate with greater speed

    step to the speed of movement of the feeding tape 3 by the deviation of the length of the layer 1 from the circumference of the drum 2. The beginning of the application of layer 1 on assembly drum 2 in this case will correspond to the place of the end of layer 1. In this case, the joining of the beginning and end of layer 1 beyond by stretching it, an annular billet of the pneumatic tire is formed. In the event that the actual length of the layer 1 is greater than the specified length, the layer 1, when applied to the drum 2, is compressed.
    In the case when the actual and predetermined values of the lengths coincide, the ratio of the speeds of the feeding tape 3 and the drum 2 is maintained the same.
    After the first layer has been superimposed on the drum 2, the next layer is superimposed taking into account the increased diameter of the drum 2. The measurement of the circumference of the drum 2 is not carried out if the angular velocity is controlled on the drum 2.
    The tape 3 can be mounted on the rocker arm 4, which is mounted on the bed 6 by means of axis 5 and through a system of levers 7 controlled by the pneumatic cylinder 8, is fed to the main drum.
    2. The latter can be adjusted to different outer diameters. The feed mite 3 is driven by an individual drive in the form of a direct current electric motor 9, through a gear belt 10, which is connected to the right side of the feed roller 3.
    With the electric motor 9, a drive 1 1 is kinematically coupled, which drives the cutting tape 12 with the cutting device 13 mounted on it for cutting layers, taken from the roll 14.
    To determine the length of layer 1, a photocell 15, mounted at the beginning of the supplying tape 3, is designed. 9. Regardless of the speed of the feeding tape 3, each received pulse corresponds to a certain feeding of the tape.

    the number of pulses according to the length 1 of layer 1, the feeding tape 3 and the cutting tape 12 are stopped and the cutting device 13 for cutting the layer 1 is activated. Then the feeding tape 3 moves the cut layer 1 so that the beginning of the feeding tape 3 reaches through the leverage system 7 drum 2. This position is adjusted and activated by another photocell 16 mounted above the feed tape 31
    For determining the actual length of layer 1, another additional pulse counter (not shown) is turned on simultaneously with the counter, which turns off when passing through layer 1 of the photocell 15. The number of pulses received from this counter is proportional to the actual length of the layer. For a better fit of the layer 1 to the feeding belt 3, a rotating retaining band 17 is installed.
    After the layer 1 has reached its position, the calculated ratio of the speeds of the drum 2 and the feed belt 3 is determined and this data is transmitted to the drives. Layer 1 is superimposed. Higher accuracy of the overlap is achieved based on the actual actual speeds of the feed belt 3 and the drum 2 at the start of the overlap. For this, the pulses from the electric motor 9 and the pulse sensor connected to the shaft of the drum 2 are compared with each other. Regulation of the synchronism of the drive maintains the frequency, repetition of the pulses of both sides at the same level.
    To improve accuracy, a disc rotor gear motor is used.
    To hold the metal filaments 1 under the feed tape 3 or the drum 2, magnets are installed.
    The proposed method allows to automate the process of applying layers to the drum.
