以後は通常の如くＴダイ21内で幅方向に均一に押し拡げ
られ、Ｔダイ21の出口から３層の多層シート又は多層フ
ィルムとして押出される。After that, it is uniformly spread in the width direction in the T-die 21 as usual and extruded from the exit of the T-die 21 as a three-layered multilayer sheet or film.
そして、各層の樹脂を入れ替えたい場合は、流路分配板
23を例えば第６図及び第７図で示すような別に準備して
ある受入れ口と供給口を連通する樹脂流路を変更した新
たな流路分配板23aに取り換えれるだけで、導管を継ぎ
替えたり、押出機の処理原料を変更したりする必要がな
く、円滑に所望の層構成をもつ多層シート等を成形でき
るものである。And if you want to replace the resin of each layer,
For example, as shown in FIGS. 6 and 7, 23 can be replaced with a newly prepared flow path distribution plate 23a in which the resin flow path that connects the receiving port and the supply port is changed. In addition, it is possible to smoothly form a multilayer sheet having a desired layer structure without the need to change the processing raw material of the extruder.
（発明の効果） 以上、詳細に説明した如く本発明によると、次の諸効果
を奏するものである。(Effects of the Invention) As described above in detail, according to the present invention, the following effects are achieved.
（１） 複合アダプタと導管との間に所望の流路分配板
を交換可能に設置し、適宜に交換することにより多層シ
ート又は多層フィルムの層構成が簡単に変更出来る。(1) The layer structure of the multilayer sheet or the multilayer film can be easily changed by arranging a desired flow channel distribution plate in an exchangeable manner between the composite adapter and the conduit and exchanging it appropriately.
（２） 層構成を変更する場合、従来のように導管を継
ぎ替えたり、押出機の処理樹脂を変更することなく行え
るので作業時間が大幅に縮少できる。(2) When the layer structure is changed, the work time can be greatly reduced because it can be performed without changing the conduits or changing the resin treated in the extruder as in the conventional case.
（３） アダプタ廻りが簡潔となり、ダイ調整のため等
の作業スペースが大きくなって、作業性が一段と向上す
る。(3) The area around the adapter is simplified, the work space for die adjustment is increased, and workability is further improved.
（４） 流路分配板は平板としたため、流路の加工が容
易であり、かつ経済的である。(4) Since the flow channel distribution plate is a flat plate, the flow channel can be easily processed and is economical.
（５） 従来、複合アダプタの上下部に各導管を接続し
ていたが、本発明にあってはアダプタに後側部から直接
継ぐことが出来、複雑な導管を必要とせず経済的であ
る。(5) Conventionally, the conduits were connected to the upper and lower parts of the composite adapter, but in the present invention, the adapter can be directly connected from the rear side, which is economical without requiring a complicated conduit.
（６） 平板状の流路分配板は、長辺方向一側部に前記
アダプタと複合アダプタに固定されるための突出する係
止部が設けられ、前記アダプタと複合アダプタをボルト
で共締めし、同ボルトを緩めると外部から挿入し、取外
しができるようにしたことにより、流路分配板の交換が
短時間で容易に実施できる。(6) The flat plate-like channel distribution plate has a projecting locking portion for fixing to the adapter and the composite adapter on one side in the long side direction, and the adapter and the composite adapter are fastened together with bolts. Since the bolts are inserted from the outside when they are loosened so that they can be removed, the passage distribution plate can be easily replaced in a short time.
