Abstract

Fish tail die producing multi-layer plastic strips. Comprises several channels supplying material. The channels change into longitudinal slits ending in internal or external nozzle lips which are elastically deformable to adjust the slit width. When adjusted to average width, the outer longitudinal slits are narrower than the inner longitudinal slit.
