The device belongs to the tire industry and can be used in the blank lines of tire carcass parts.

A device for orienting a tape material is known, which contains a mechanism for mixing material in the transverse direction relative to the material supply, made in the form of uniformly across the width of the material of infinite elastic elements tensioned on a rotator, and rollers fixed on the plate 1.

The disadvantage of the device is the complexity of its design, as well as the need to readjust the device when switching to a different size of the centered material.

Closest to the invention of the technical essence and the achieved result is the device, containing one of its rollers mounted on holders that are installed in the supports, and the drive for turning the rollers 2).

However, when orienting a material, moving it with low tension, the frictional force arising from the contact of the material with the rollers is insignificant and does not ensure mixing of the material in the required direction. There is a slippage of the material relative to the rollers, which leads to a decrease in the orientation accuracy.

The aim of the invention is to improve the orientation accuracy of the material.

The goal is achieved by the fact that a device for orienting tape material, containing one row of rollers mounted on holders that are installed in supports, and a drive for rotating the rollers, is provided with a second row of rollers mounted parallel to the first row and two rows additional rollers mounted above the first and second rows, respectively, one opposite the other, and the supports of the second and additional rows mounted above it are rigidly connected by means of a fork lever connected to the drive m turning rollers.

In addition, infinite elastic cords are installed on the lower and upper rows of rollers.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one.

The device comprises two rows of 2 and 3 rollers mounted on frame 1, mounted parallel to one another on holders 4, which are fixed in bearing supports 5, drive 6 for rotating rollers, and sensor 7 for controlling the lateral edge of the material.

Above the first and second rows 2 and 3 of the rollers, respectively, two rows of 8 and 9 additional rollers are mounted opposite one another, which are also mounted on holders 10 fixed in bearing supports 11.

The supports 5 and 11 are rigidly connected with a fork lever 12 by means of a hinge 13. The lever 12 is connected to the drive 6. On the lower and upper rows 2, 3 and 8, 9 of the rollers, endless elastic cords 14 and 15 are installed by means of pulleys.

The device works as follows.

The material 16 is fed to the rollers. In this case, the tape of material 16 passes between two branches of endless cords 14 and 15. Due to the frictional force between material 16 and cords 14 and 15, the latter move at a feed rate of material 16. The position of the lateral edge of the material 16 is monitored by sensor 7. If there is an offset side the edges of the material relative to the nominal position, then the sensor 7 sends a signal to the actuator, in accordance with which the reversing actuator 6 moves the lever 12, it in turn turns the holders 4 and 10 with pulleys on which they are pulled endless cords 14 and 15 in bearing supports 5 and 11. As a result of rotation of the holders 4 and 10, a certain angle is also formed between the direction of flow of the material 16 and the direction of movement of the endless plugs 14 and 15. As it ensures the absence of slippage of the material 16 relative to marks 14 and 15 The material 16 will be caught by the cords 14 and 15 and displaced by them in the direction of movement of the lever 12. In this case, the greater the movement of the lever 12, the greater the amount of material 16 will move in the same direction.

When a material 16 is displaced in the opposite direction from the sensor 7, the corresponding signal is fed to the actuator 6, as a result of which the actuator 6 moves the lever 12 to the other side. In the future, the cycle of operation of the device is similar.

The proposed device eliminates material slippage in the displacement mechanism and improves orientation accuracy. In addition, the device does not require high tensioning of the material, and consequently, it exposes the tape material to significant deformations leading to a product marriage.
