Abstract

A spinneret bundle for producing fibers from a polymer melt includes an elongated nozzle plate that has a feed channel on an upper face and at least one row of nozzle bores that are arranged next to one another on a lower face. A distributing plate lies on the upper face of the nozzle plate and has a distributing chamber that faces the feed channel and a melt inlet that is connected to the distributing chamber. A perforated plate with a plurality of through-bores is provided between the distributing chamber of the distributing plate and the feed channel of the nozzle plate in order to achieve a redistribution and uniformity of the melt when the melt is introduced into the feed channel.
