Abstract
A spinneret assembly for melt spinning a plurality of strand-like filaments, which includes a plurality of internal parts composed of at least one inlet componentand a spinneret platewhich are braced relative each other in a housingby a supporting means. The inlet componentforms a melt inletand the spinneret plateforms a melt outlet by means of a plurality of spin holesTo achieve during operation a self-sealing between the internal parts, the invention provides for arranging an expansion bodybetween the housingand one of the internal parts. The expansion bodyis formed of a material which has a higher thermal expansion coefficient than the housing material, and it generates, upon being heated, a pressure force inside the housing which provides for a self-sealing bracing of the internal parts.
