Zusammenfassung:A process for manufacturing continuous fibers from the thermoplastic materials melt comprises preparation of the melt, shaping "onion-like" elements from the melt with a continuously acting hydrostatic pressure of the melt, stretching the continuous fibers out of "onion-like" elements, oiling thereof and winding on reels rotating around axis thereof, spreading the continuous fibers along the reels length. The continuous fibers being produced in an uninterrupted mode in several operations of stretching made in series with an additional heating preliminarily extracted fibers to a thermoplastic state providing a uniform speed for each operation of fibers stretching plus additional speed for thinning thereof in the diameter.
