Abstract

An apparatus for making filaments has a spinneret plate having a row of holes from which emerge filaments. A manifold distributes a supplied plastic melt over a starting spinning width. A filter plate is downstream of the manifold. A pack of distributor plates is downstream of the filter plate. The distributor plates each have a plurality of distributor holes distributed over a manifold width. The distributor holes receive the plastic melt emerging from the filter plate. The spinneret plate is downstream of the distributor-plate pack and has a row of spinneret passages extending over a final spinning width aligned with the spinneret holes. An output face of the filter plate turned toward the distributor-plate pack and/or an inlet face of the spinneret plate turned toward the distributor-plate pack is curved or crowned at least in sections.
