- 1 - Abstract: A multi-extrusion die assembly for thermoplastic materials avoids undesirable oozing out or exuding of thermoplastic material through mating surfaces between a die box and a preformer and undesirable deformation of extruded material at introducing passages by improve- ments in the disposition of the extruders and in the construction of the die box and preformer. Attaching and detaching of a block and a lower box with respect to the die box are also facilitated for efficient extrusion.
