CA 2084354

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.

Cette invention concerne une plaque placée en amont d'une filière et possédant des canaux cylindriques dont au moins certains ont un premier diamètre. Chacun des canaux est aligné sur un alésage de la plaque-filière. Le nombre et la grosseur des filaments extrudés peuvent être modifiés par simple remplacement de la plaque qui assure l'obturation des alésages de la plaque-filière par déformation sous la pression d'extrusion.
