Simply made, cheap assembly of spinnerets for multicomponent threads

摘要

In an arrangement of spinnerets for spinning multicomponent threads comprising at least two different material components the melt to be spun is fed via at least two separated melt channels each with a different component and it emerges via spinneret drill-holes. The channels (14) are located in a distribution piece (5) containing groove-like distribution channels (13) associated with each melt channel. A plate (4) with spinneret drill-holes is connected with the distributor piece so that inlet openings of several lie below the appropriate distribution channel and at least a proportion of the drill-holes are so located that their spinneret exits run together.
