Abstract: When a coating composition is applied to a web, the composition is applied in excess, and the excess is wiped off with the help of a portion of the web which has not yet been coated.

Abstract: In coating a strip of material, such as web of paper, it is passed over a support member forming one of the enclosing surfaces of a closed chamber. The closed chamber is arranged to operate under vacuum conditions. Coating liquid is supplied in excess to the closed chamber to form a layer on the surface of the strip. At the end of the coating action, as the strip leaves the closed chamber, it is contacted by a movably positionable blade which provides a wiping-off action on the strip so as to remove the excess of coating liquid from the strip. The vacuum inside the closed chamber urges the blade against the strip. Therefore, it is possible, by varying the vacuum, to vary the amount of coating liquid adhering to the strip leaving the closed chamber.

Abstract: A coating composition is applied to a paper web while the web passes over an opening in a box in which a partial vacuum is maintained. The opening is divided into two sections by means of a support member disposed perpendicular to the direction of travel of the web. The coating composition is applied to the web in the downstream section of the opening, and the upstream section is considerably greater in area than the downstream section to create a tension on the web and thereby eliminate unstretched areas in the web.

Abstract translation: 当纸幅通过保持部分真空的盒子中的开口时，将涂料组合物施加到纸幅上。 通过垂直于幅材行进方向设置的支撑构件将开口分成两部分。 将涂料组合物施加到开口的下游部分中的幅材上，并且上游部分的面积比下游部分大得多，以在卷筒纸上产生张力，从而消除卷材中的未拉伸区域。

Abstract: A chamber having an opening in its wall contains a roller. A portion of the surface of the roller is situated in the opening. A web is continuously moved past the chamber so as to cover the opening. A vacuum is created in the chamber. The external pressure forces the web into contact with the roller. A coating liquid is supplied into the chamber so as to wet the roller. The roller is rotated so that the coating liquid is transferred to the web.
