Abstract: An improved film coater which utilizes one or more coater or applicators to transfer coating to the outer surfaces of at least one more rolls, which in turn transfers the coating from the roll surface to one or more sides of the web for coating paper is disclosed. The coater or applicator includes a smoothing doctor on the web and downstream of the one or more rolls, and may also utilize humidity from one of steam showers or a humidity enclosure to assist smoothing. The web may run in any direction, but preferably runs upwardly from the roll toward the doctor to reduce nullfilm splitnull droplets effect. The present invention also reduces the fiber rise and arrange peel pattern on the coated web, resulting in a smooth uniform coated paper.

Abstract translation: 公开了一种改进的薄膜涂布机，其利用一个或多个涂布机或涂布器将涂层转印到至少一个以上的辊的外表面上，其又将涂层从辊表面转移到用于涂布纸的幅材的一个或多个侧面。 涂布机或涂布器包括在幅材上的平滑刮刀和一个或多个辊的下游，并且还可以利用来自蒸汽淋浴或湿度外壳之一的湿度来辅助平滑化。 网可以沿任何方向运行，但是优选地从卷朝向医生向上延伸以减少“膜分裂”液滴效应。 本发明还减少了纤维上升并且在涂布的织物上布置了剥离图案，导致光滑均匀的涂布纸。
