摘要： This publication describes a short-dwell coater for coating a web with coating mix against a rotating backing roll. The coater comprises a support structure, a feeder means adapted to the front lip for feeding the coating mix into an application zone formed between the backing roll and the support structure, and an actual doctor blade, adapted into the support structure to press against the web, with which blade the excess coating mix passing over form the application zone can be removed. According to the invention, a separate predoctoring blade is adapted at a short distance before the actual doctor blade in the machine direction of the web for smoothing out disturbances in the coating mix flow before the mix proceeds up to the actual doctor blade.

摘要： The invention concerns a blade coater and a method for coating a web backed by a rotatable backing roll. The blade coater unit includes a support structure, a feeder mounted to the support structure and capable of feeding the coating mix onto the web when brought close to the web in running conditions, and a smoothing device arranged to the immediate vicinity of the web for the application of the fed coating mix. The blade coater unit is essentially placed below the backing roll, the smoothing device is a flexible blade having a tip inclination angle .alpha. less than 20.degree., and the feeder has a narrow exit opening arranged to the stem of the flexible blade without any essential steps in order to facilitate a fast, laminar flow of the coating mix. The approach in accordance with the invention achieves a coat of high quality.
摘要翻译：本发明涉及一种刮刀涂布机和一种用于涂覆由可旋转背衬辊支撑的织物的方法。刀片涂布机单元包括支撑结构，安装到支撑结构的进料器，并且当在运行状态下靠近卷筒纸时能够将涂料混合物馈送到卷筒纸上;以及平滑装置，布置成靠近卷筒纸，用于施用进料涂料混合物。刀片涂布机单元基本上放置在背衬辊的下方，平滑装置是具有尖端倾斜角α小于20°的柔性刮板，并且进料器具有窄的出口，布置在柔性刮板的杆上，没有任何必要的步骤以便促进涂层混合物的快速，层流。根据本发明的方法实现了高质量的外套。
