Abstract: The specification describes a spinneret unit for spinning textile filaments, in which the spinneret is mounted at the downstream end of the housing. Within the housing is mounted a first filter, having filter elements having a check threshold which decreases in the downstream direction. The flow rate is increased in a conduit of decreasing cross-section and the material then passes through a second filter located immediately upstream of the spinneret, the second filter having a check threshold no greater than any of the first filter elements.
