In order that the based product where 2 differ at least forms the stratified simultaneous extrusion molding products style it unites striped condition or the production device of the variegated condition product and, in order to be brought together, simultaneous it pushes out this based product to the common passage and the expedient which forms, the die/di expedient which receives the stratified simultaneous extrusion molding products style (10) it includes. It divides the stratified simultaneous extrusion molding products style, into the secondary flow of 2 where you follow the rotary road around each separate stratified simultaneous extrusion molding products at least, in order continuously to make the single recombination products recombine style where this at least 2 layer re-orientation has been done secondary flow, die/di expedient (10) it is constituted. As for the die/di, the passage where the products style circulate (47) the spiral screw 1 or more it is attached to stationary type (48,49) it is possible to possess. The point of each screw divides the products style into secondary flow, secondary flow before being recombined in the locus edge of the last screw, flows either of the screws according to side. Also the method of corresponding is disclosed.ストライプ状又はまだら状製品の製造装置は、少なくとも2個の異なるベース製品が層状同時押出し成形製品流を形成するべく組み合わさるように、このベース製品を共通の流路へ同時押出し成形する手段と、層状同時押出し成形製品流を受け取るダイ手段(10)を含む。層状同時押出し成形製品流を、各々の周りで回転路に従う少なくとも2個の別個の層状同時押出し成形製品の副流に分割し、続いてこの少なくとも2個の副流を層が再配向されている単一再結合製品流に再結合させるように、ダイ手段(10)は構成される。ダイは、製品流が流通する通路(47)に固定式に据付けられる1個以上の螺旋スクリュー(48,49)を有してよい。各スクリューの先端は製品流を副流に分割し、副流は最終スクリューの軌跡端において再結合される前に、スクリューのいずれか側に沿って流れる。対応する方法も開示される。
