    • For applying a liquid, such as liquid wax, to a continuously fed sheet material a first pair of cylindrical rollers, each having a smooth surface which is exposed to and wetted by the liquid to be applied, are rotatably mounted about substantially parallel axes and spaced apart to permit intimate tangential contact therebetween with both sides of the sheet material to be coated. A second pair of cylindrical rollers located a distance from the first pair are similarly mounted and positioned to make contact with the sheet material in like manner. A pair of cylindrical engraved rolls, each having an array of guadrangular cells formed along the surfaces thereof, are respectively positioned between each of the first and second pairs of rollers and are rotatably mounted on movable axes so that the engraved rolls urge against one or both of the roller pairs during rotation. The quadrangular cells serve to provide a multiplicity of miniature cups that remove a certain fraction of the liquid from the surfaces of the first pair of rollers thereafter transferring the fraction to the surfaces of the second roller pair which in turn deposit the fraction on the sheet material to effect improved continuous coating of the sheet material.
    • 为了将液体(例如液体蜡)施加到连续供给的片材上,第一对圆柱形辊子(其具有平滑的表面暴露于待涂覆的液体并被其润湿)可旋转地围绕基本上平行的轴线安装并且间隔开 分开以允许与待涂覆的片材的两侧之间的紧密切向接触。 与第一对距离一定距离的第二对圆柱滚子被类似地安装和定位成以类似的方式与片材接触。 一对圆柱形雕刻辊分别位于第一和第二对辊对之间,每一个具有沿着其表面形成的瓜德隆细胞阵列,并且可旋转地安装在可移动轴上,使得雕刻的辊推动一个或两个 的辊对。 四边形细胞用于提供多个微型杯,其从第一对辊的表面移除一定部分的液体,然后将该部分转移到第二辊对的表面,而第二辊对的表面又沉积在片材上 以实现片材的连续涂覆。
