Zusammenfassung:	PROBLEM TO BE SOLVED: To provide improved manufacturing equipment which substantially reduces or eliminates smear in component co-extrusion manufacturing.SOLUTION: An extruder assembly for forming a multi-layered composite comprises an extruder head having a first flow passage and a second flow passage, a first extruder and a second extruder in fluid communication with the first flow passage and the second flow passage respectively, and a splice bar 302 which has a first passageway and a second passageway that extend from a rear side to an outlet side and communicates a flow from the first passageway and the second passageway to an outlet die 400. The splice bar 302 further comprises a groove 370 located on the rear side and positioned between the first passageway and the second passageway.SELECTED DRAWING: Figure 2 【課題】共押出しで構成要素を製造する際のスミアを大幅に減少させるかまたは無くす、改善された製造装置を提供する。【解決手段】多層の複合物を形成する押出機アセンブリが、第１の流路および第２の流路を有する押出機ヘッドと、第１の流路および第２の流路とそれぞれ流体連通している第１の押出機および第２の押出機と、後方側から出口側へ延びている第１の通路および第２の通路を有しており第１の通路および第２の通路から出口ダイ４００に流れを伝えるスプライスバー３０２と、を有する。スプライスバー３０２は、後方側に配置されており第１の通路と第２の通路との間に位置する溝３７０をさらに備えている。【選択図】図２
