摘要： In a coating method of extruding a coating liquid through a slit of an extrusion-type coating head to coat a running web, at a starting or restarting of the coating, the coating liquid is extruded through the slit of the coating head while the coating head is away from the web, and then the coating is started while a slightly large clearance is kept between the coating head and the web at the upstream side of the coating head, thereafter changing the coating state or arrangement to a steady coating state. Therefore, occurrence of a thicker portion of the coating film on the web at the start of the coating can be prevented. Further, at the end or interruption of the coating, the coating state or arrangement of the coating head is changed from the steady coating state to a state wherein a slightly large clearance is kept between the coating head and the web at the upstream side, and the coating head is moved away from the web to end the coating. Therefore, occurrence of a thicker portion of the coating film on the web at the end of the coating can be prevented. With this arrangement, at the start, restart, end and interruption of the coating, a uniformly coated film can be also formed on one surface of the web whose other surface has already been coated with a coating liquid.
摘要翻译：在通过挤出型涂布头的狭缝挤出涂布液以涂布流动纤维网的涂布方法中，在涂层的开始或重新开始时，涂布液通过涂布头的狭缝挤出，同时涂布头离开纸幅，然后开始涂布，同时在涂布头的上游侧在涂布头和纸幅之间保持略大的间隙，然后将涂布状态或布置改变为稳定的涂布状态。因此，可以防止涂层开始时在卷筒纸上产生较厚的涂膜。此外，在涂层的末端或中断时，涂布头的涂布状态或布置从稳定涂布状态改变到在涂布头和在上游侧的纸幅之间保持略大的间隙的状态，以及涂布头从纸幅移开以使涂层结束。因此，可以防止在涂布结束时在卷筒纸上出现较厚的涂膜。通过这种布置，在涂层的开始，重新启动，结束和中断的情况下，也可以在其另一表面已经涂覆有涂布液的幅材的一个表面上形成均匀涂布的膜。

摘要： An extrusion coating head which is disposed between a drier for performing a non-contact drying operation and a support roll located at the upstream side of and nearest to the drier is designed so that a back edge surface thereof is designed to have an round surface having a radius of curvature R which satisfies the following inequality: 3 mm.ltoreq.R.ltoreq.30 mm, and the entire R-surface portion of the back edge of the coating head is located at a position higher than a tangential line drawn to the front edge surface at a slit-side edge point of the front edge so as to project toward the web side. The running web is coated with the coating liquid by the extrusion-type coating head, and then dried through a non-contact drying process.

摘要： A magnetic paint is extrusion coated to a length of splice jointed webs through a coating head by continuously feeding the length of webs across the head. When a splice joint passes across the head, the head is moved apart from the web before passage and contacted with the web after passage. Objectionable coating portions which are formed as a result of moving the head out of and into contact with the web are scraped off by a scraping roll downstream of the head.
