Abstract

A device for melt spinning multi-component fibers including at least two melt inlets for introducing separately guided melt components is presented. The device includes a feed plate having a plurality of feed channels for distributing the melt components, a distributor block associated with the feed plate, and a nozzle plate adjoining the distributor block and including a plurality of nozzle bores, wherein the distributor block has several thin distributor plates stacked on top of each other and each have a hole pattern with multiple distribution openings. The thin distributor plates are configured inside the distributor block such that a plurality of melt channels form, which connect the feed channels of the feed plate to the nozzle bores of the nozzle plate. In order to implement high flow volumes, multiple distributor plates having identical hole patterns of the distribution openings are stacked in a tightly sealing manner inside the distributor block.
