摘要： A slide-hopper-type coating method in which the viscosity of the coating solution forming a free-falling curtain and the angle .alpha. which the front edge of the lip of the slide hopper forms with respect to the horizontal are selected with respect to the flow rate of the curtain in such a way that the line of contact between the curtain and the web is concave with respect to the direction in which the web travels. In addition, the angle .beta. which the extension of the curtain in the direction of its fall forms with respect to the direction of travel of the web at the point where the curtain is deposited on the web is preferably adjusted so that it is an obtuse angle not larger than 140.degree.. By satisfying these conditions, the coating method of the present invention is capable of extending the upper limit of coating speeds without causing "sagging" in the range of high flow quantities of coating solution per unit length of curtain coat width.

摘要： A curtain coating method and apparatus using a rotatable or slidable coating plate and in which a coating liquid freely falls in the form of a thin film from a hopper. The thin film collides with a web continuously running and circumferentially turning around a backup roller to coat the web. The coating plate is rotated or slid to retract so that the freely falling coating liquid reaches the web so as to coat the web after the freely falling coating liquid flows along a checking plate which is doglegged in section and provided on a forward end of the coating plate, thereby coating the web with an even thickness at the start of coating operations.

摘要： In curtain coating for multiple layers consisting of lower most layer, uppermost layer and intermediate layer, using coating liquid having viscosity more than 300 mPas for one layer or more of multiple layers improves amazingly the curtain coating stability against disturbance such as passing spliced portion of running web. The one layer or more layers for which coating liquid having viscosity more than 300 mPas is to be used is selected from intermediate layer. The curtain coating stability is further improved by combining the high viscosity coating liquid for intermediate layer with other technologies such as electrifying web, heating web upstream of coating point and/or keeping web tension higher than some specified value.

摘要： Before the start of coating, a deflector receives a curtain of a coating liquid free-falling from a coating hopper in order to prevent a continuously-running web from being coated with the coating liquid. At the start of the coating, the deflector is moved relatively to the coating hopper, so that the coating liquid can start to be applied to the web. A receding part is formed at the end of the deflector.
