Patent ID: 7172401

Claim:
A spinneret assembly for melt spinning a plurality of strand-like filaments and comprising an external housing, a plurality of internal parts positioned in the housing and including at least one inlet component and a spinneret plate, with the inlet component including a downstream side which defines a distributor chamber within the housing and an inlet for admitting a melt into the distributor chamber in the interior of the housing and with the spinneret plate positioned on the downstream side of the inlet component so as to communicate with the distributor chamber and including a plurality of spin holes which serve as a melt outlet from the housing, means joined to the housing for supporting the internal parts relative to each other in the housing, and at least one expansion body arranged in the housing between the housing and an upstream side of the inlet component, with the expansion body being formed of a material which has a higher thermal expansion coefficient in comparison to that of the housing material, and with the expansion body being positioned such that upon being heated a pressure force is generated which provides a self sealing bracing of the inlet component toward the spinneret plate.
