Apparatus for spinning different colored filaments from a single
spinneret
摘要:
A spin pack for spinning multiple components includes a distribution device which distributes mutually separated molten polymer streams to a spinneret so that each mutually separated molten polymer stream is accessible at each active spinneret backhole. Intermediate the spinneret and the distribution device, a selection assembly selects which, if any, mutually separated molten polymer stream flows into which backhole.
