ABSTRACT:
Device for the production of multicomponent fibers or of filaments, in particular bicomponent fibers, whereby a nozzle block assembly is provided. The assembly consists of a middle nozzle block and two outer nozzle blocks. Arranged in the nozzle block assembly are at least two inflow channels, each for a melt flow of one component. At the lower end of the nozzle block assembly is a nozzle with apertures for the outlet of the multicomponent strands. At least one inflow channel runs over at least a part of its length exclusively through an outer nozzle block.
