摘要

The device includes two groups of multiple spin nozzles attached to spin pumps (8.1,8.2), where two groups of filament (38,39) bundles are extrudable by the two groups of spin nozzles. The composite filament (29) is formed by the combination of the two groups of the filament bundles. A melt source (1) is provided for the supply of a polymer melt. The spin pumps are connected over multiple melt lines with the melt source and over multiple distributor lines with the spin nozzles. A feeding device (3) is connected with a spin pump for the supply of an additive by a separate feed line (5).
