Abstract
A sealing plate upstream of a spinneret has cylindrical flow channels, at least some of which have a first diameter. Each of the flow channels corresponds in position to a bore in the spinneret plate. The number and denier of extruded filaments can be altered by simply changing the plate. The plate provides a seal by deflecting under the extrusion pressure.
