Abstract
Core filaments for the formation of a fleece are formed in a spinneret assembly which has a wide slit extrusion die provided with two outlet slits for different thermoplastic synthetic resins. Below the die, a distribution plate has two sets of feed bores which deliver synthetic resin from the two sets of bores to a core-forming plate directly beneath the distribution plate and a spinneret plate below the core-forming plate whose spinneret bores are aligned with core-forming bores in the core-forming plate.
