Abstract
In the manufacture of a continuous thread coated with a mixture which reacts to ultraviolet radiation, a large number of continuous filaments are formed by mechanically drawing a large number of molten thermoplastic material streams flowing from openings in at least one device. A mixture in the liquid state which can react under the effect of ultraviolet radiation is deposited onto the surface of at least some of the filaments before they are combined to form at least one thread. The thread is wound into the form of a winding on a rotating support, and exposed to ultraviolet radiation during the winding operation.
