<p>A multi-extrusion die assembly for use in a multi-extrusion arrangement (M) for thermoplastic materials in which undesirable oozing out or exuding of thermoplastic material through the mating surface between a die box (D1) and preformer (26) or deformation of extruded material at a second introducing passage (22), etc. are prevented through improvements in the disposition of the extruders (A1,B1,C1) and the construction of the die box (D1) and preformer (26), whilst attachment and detachment of a block (27) and a lower box (25) with respect to the die box (D1) are facilitated for efficient extrusion.</p> |
