Title (EN) AIRFLOW CONTROL DEVICE AND METHOD FOR MANUFACTURING STRETCHED FILM
(FR) DISPOSITIF DE RÉGULATION D'ÉCOULEMENT D’AIR ET PROCÉDÉ DE FABRICATION DE FILM ÉTIRÉ
(JA) 気流制御装置および延伸フィルムの製造方法
Abstract:
(EN) This airflow control device is installed adjacent to the upstream side of an inlet of and/or downstream side of an outlet of a tenter oven. The airflow control device has therein a box-shaped cover which extends in the film traveling direction and of which a film traveling surface-facing surface is open, wherein at least one partitioning structure extending in the film width direction is provided inside the box-shaped cover, the box-shaped cover is partitioned into a plurality of chambers by the partitioning structure, and air is discharged to the outside by means of an air discharge mechanism provided in at least two of the plurality of chambers.
(FR) Le dispositif de régulation d'écoulement d'air selon l'invention est installé de manière adjacente au côté amont d'une entrée et/ou au côté aval d'une sortie d'un four à rame. Le dispositif de régulation d'écoulement d'air comporte en son sein un couvercle en forme de boîte qui s'étend dans la direction de déplacement du film et dont une surface faisant face à la surface de déplacement du film est ouverte, au moins une structure de séparation s'étendant dans le sens de la largeur du film étant disposée à l'intérieur du couvercle en forme de boîte, le couvercle en forme de boîte étant divisé en une pluralité de chambres par la structure de séparation, et de l'air étant évacué vers l'extérieur au moyen d'un mécanisme d'évacuation d'air disposé dans au moins deux chambres de la pluralité de chambres.
(JA) 本発明は、テンターオーブンの入り口の上流側および/または出口の下流側に隣接して気流制御装置を設置する。気流制御装置内には、フィルム走行方向に延在し、フィルム走行面に対向する面が開口している箱状体カバーがあり、箱状体カバーの内部にフィルム幅方向に延在した仕切り構造体を少なくとも1つ有し、仕切り構造体によって箱状体カバーが複数の室に区分けされていて、複数の室の少なくとも2室に備えたエア排気機構で外部へエアを排気する。
