The size of the winding equil is 1.9x 1x 1.4 m. The textile fiber is processed in the main by drawing it through a die of a platinum-rhodium glass-melting container filled with glass balls. The moldings are prepared from nonalkaline glass containing 10%o B2O3. The length of the moldings is 100+1 mm. They automatically advance to the upper orifice of the glass-melting container with the aid of a special loader in the form of a toothed drum. The vessels have 100, 200 and 250 dies. On the way from the pan to the winding drum there is fixed a split channel with a draw-off tube which allows epoxide resin dissolved in carbon tetrachloride to be used as lubricant On the fiber is applied up to 1 o of lubricant. An automatic clamp for the glass fiber is supplied in the winding apparatus Three bobbin holders are fixed at an angle of 120 to a table which rotates periodically. when th rotates with the aid of a foot pedal the bobbin comes out of the friction engagement, and the new bobbin gets caught up with the frictional roller, constantly rotating from the electric motor. The diameter of the bobbin is 150 mm rpm 3000. The winding is crossed over the whole length of the bobbin, winding lasts for 10 minutes. Experimental equipment for processing superfine fiber.

The primary fiber coincides with the stream of hot gases at a distance of about 10-15 mm from the exit aperture. The superfine fiber advances to the change-over chamber 1x 1x 2m in size, stretched with a metallic lattice.

They automatically advance tothe upper orifice of the glass-melting container with the aid of a special loader in the form of a toothed drum. The vessels have 100, 200 and 250 dies. On the way from the pan to the winding drum there is fixed a split channel with a draw-off tube which allows epoxide resin dissolved in carbon tetraehloride to be used as lubricant. On the fiber is applied up to 1%0 of lubricant. An automatic clamp for the glass fiber is supplied in the winding apparatus. Three bobbin holders are fixed at an angle of 120" to a table which rotates periodically.
