Abstract:
An apparatus for the spinning of liquid polymer to produce polymer filaments where the liquid polymer flows through a polymer duct with a first heating jacket to a spinning pump with a second heating jacket, which displaces the polymer through a plurality of conduits to spinning packets and which is then extruded through spinnerets downwardly to form filaments, whereby the conduits downstream of the spinning pump, the spinning packets and the spinnerets are disposed in at least one spinning housing which is traversed by a heating fluid in the form of a vapor, a distance of at least 5 mm being provided between the spinning housing traversed by the heating fluid on the one hand and the first and second heating jackets and the spinning pump on the other hand, a heating fluid from a second supply being admitted into the first heating jacket, and the temperature of the heating fluid in the form of a vapor supplied to the spinning housing is 10 to 40Â° C. higher than the temperature of the heating fluid that is fed to the first heating jacket, the second heating jacket, which surrounds the spinning pump, being fed with heating fluid from the spinning housing.
