The invention relates to devices for winding tapes on shaped tubular products such as tees and crosses, and can be used to apply reinforcing and insulating coatings on shaped products mainly from brittle materials. The purpose of the invention is to expand the range of processed products. FIG. 1 shows a machine, a general view; in fig. 2 - the position of the rollers and the holder at the beginning of the bending around with the tape of the process; in fig. 3 - the position of the rollers and the holder at the end of the bending around with a tape of the process; in fig. 4 - the position of the machine nodes when winding tape on the process. The machine has a drive in the form of an electric motor 1, a gearbox 2 with an output shaft 3, which drives the rotation through the adjusting nut 4, the winding unit. The latter includes a housing 5, on the console end of which a reel 6 with a tape 7 and a bath 8 are mounted. A glass product, for example a tee 9 with a holder (clamp) 10 to the crossbar 11. The machine also contains two parallel copiers 12, installed vertically, working the profile of each of which is made with straight and curved zigzag sections. The latter corresponds to the location of the appendix 13 on the product and ensures the rotation of the product in the plane of its working movement at an angle corresponding to the angle between the turns of the winding tape located on the main part of the tubular product on opposite sides of the appendix. The working surface of each of the copiers 12 is the surface of the groove 14, in which the running rollers 15 are connected by upper and lower shafts 16 in pairs, the distance between which exceeds the unfolded length of the shaped part (the length of the main straight part plus the length of the process). The condition of keeping the distance between the rails 15 is necessary in order to ensure a straight linear movement of the lower pair of rollers 15 through the grooves 14 when winding along the entire length of the main part of the part 9 and the length of the appendix 13, except for the zone of the bent groove 14. When passing the upper shaft 16 of the curved section groove 14, the shaft 16 goes first in one direction, then in the other (Fig. 2 and 3). Thus, through the cross member 11, the holder 10 transmits the parts 9 in an oscillating motion, providing a detour by tape 7 of the process 13 of the part 9. The oscillatory movement of the detail 9 should occur synchronously with the upper shaft 16 of the pair during one revolution of the tape 7 to the round. Details 9. The rolling rollers 15 are interconnected and with another pair of rollers 15 placed in the groove of the other copier 12, shafts 16. At the output end of the upper shaft 16, the cross member 11 is mounted, and in the central part there are fixed the shafts 17 of the hydraulic cylinder 18, hinged to the bed 19, which constitutes a mechanism for moving the holder. The holder rotation mechanism from the winding position of the main part of the tubular product to the tape winding position on the process consists of a frame 20, rigidly fixed on the upper shaft 16, a hydraulic cylinder 21, the stem of which 22 is hinged to the frame 20, and the cylinder body 21 with the lower shaft 16 The hydraulic cylinder 21, through the frame 20, causes the shaft 16 to rotate, together with the cross member 11 and the holder 10. The shafts are interconnected by means of the rods 23 into the carriage. hydraulic cylinders 18 and 21 are supplied with liquid through pipelines 24 and removed from these hydraulic cylinders through pipelines 25. Pipelines 24 and 25 are connected to the hydraulic distributor 26 and pump 27. Rollers 15 are located (Fig. 4) in the straight lines of the copier 12. The crossbar is turned in such a way that the appendix is turned down. The device works as follows. After the belt 7 is filled, the electric motor 28 with the pump 27 turns on the main part of the shaped part 9. After creating the necessary pressure, an electric motor 1 and a distributor 26 turn on simultaneously through an electric manometer (not shown). The electric motor 1 sets the winding unit in motion and starts the rotation of the bobbin 6 with the impregnating the bath 8 and the tape 7. The distributor 26 through the spools creates a pressure of fluid in the lower part of the cylinder 21 of the holder rotation mechanism - for fixing the molded part 9 in a vertical position, and feeding This fluid in the lower part of the cylinder 18 of the mechanism for moving the holder, the piston of which with the rod 17 begins to move upwards. The movement of the piston, and with it the shaft 16 with the cross member 11 and the molded part, is carried out synchronously with the rotation of the reel 6. After winding the tape 7 onto the main part 9 of the tubular product, the electric motor 1 is turned off via an end switch (not shown) and the winding unit stops. The synchronous movement of the piston rod 17, and with it the shaft 16 with the cross bar 11, is carried out depending on the winding pitch and is determined by calculating the amount of fluid supplied to the cylinder 18 through the distributor 26 per shaft rotation.

In the distributor 26, the switch moves to the base of the mechanism for moving the holder, namely, stopping the supply of liquid to the cylinder 18. The mechanism for rotating the holder is activated by depressurizing the lower part of the cylinder 21 and creating pressure in the upper part of the cylinder 21. The pressure of the liquid in the lower part of the cylinder 18 is left for fixing the mechanism for moving the holder in the reached position.

When creating pressure in the upper part of the cylinder, shaft 16 is rotated, and with it, cross members 11 with a tubular product through 90 ° and fixed in this position. Then, the tape is loaded onto the spike 13, the winding unit is again turned on by means of the electric motor 1 and the distributor 26, and liquid is supplied to the lower part of the cylinder 18 of the mechanism for moving the holder.

The carriage continues to move upwards and the tape is wound on the spike 13. After winding the tape onto the spike 13, the electric motor 1 stops using the end switch (not shown) and the distributor 26 shuts off the flow of liquid to the bottom of the cylinder 18. The distributor turns on the holder turning mechanism and produces reverse rotation 90 ° of the shaft 16 to the initial position by supplying fluid to the upper part of the cylinder 18, which accelerates the movement of the carriage with the shaft 16 to the initial position.

Since the machine is designed for applying reinforcing and insulating coatings, the impregnating bath 8 contains a liquid, for example, an epoxy resin, which has the property of adhesion with the material of the product 9, as well as having the property of curing after a certain time. The reinforcement tape 7 in the bath is soaked with liquid and easily refilled manually (using protective agents, for example,

on any part of the product). Hand pruning.

In order to save time, it is advisable to make a winding on the product in batches. First, the winding is carried out on the main, part of the product. Then the product

5 those that have passed through the curing process, reassemble the iron on the machine one at a time and wind the tape on the processes.

It is more expedient to wind the tape onto the main part of the batch of products, and then readjust it to the process of winding the process than to readjust the machine to each product.

Using the proposed machine allows to mechanize the process of obtaining

r hardening coatings not only on glass tees and crosses, but also on plastic and metal. In comparison with the known hand-held devices for winding tapes on glass products such as crosses and tees, the proposed machine provides high winding performance and widening of the product range.
