摘要

Spinneret device comprises at least one elongated nozzle plate (1) comprising a supply channel (3) on the upper side (8) and at least one row of adjacently arranged nozzle openings (4) on the bottom side (7). The nozzle openings are formed at the bottom side through bores, which are connected with the supply channel on the upper side. The nozzle openings are formed in the nozzle plate through many straight parallel bores and many inclined oblique bores, which form a common bore series within the nozzle plate alternately according to a pattern.
