摘要： Drying a coated substrate which includes magnetic particles includes a condensing surface spaced from the substrate. This creates a longitudinal gap between the substrate and the condensing surface. Liquid is evaporated from the substrate to create a vapor and the vapor is transported to the condensing surface without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.
摘要翻译：干燥包括磁性颗粒的涂布基材包括与基材间隔开的冷凝表面。这在基板和冷凝表面之间产生纵向间隙。液体从基板蒸发以产生蒸汽，并且蒸气被输送到冷凝表面，而不需要施加对流。蒸气在冷凝表面上被冷凝，产生从冷凝表面去除的冷凝物。使用超过重力进行去除，而不会导致冷凝膜的不均匀性发生。通过使涂覆的基底经受在干燥器空间外部的位置产生的磁场，磁性颗粒被定向在涂覆的基底上。

摘要： A wet gravure coating of fine magnetizable particles can be smoothed by a rectangular piece of flexible film that is secured at one end in flat jaws of a clamp to leave its opposite end free to drag against the coating, thus causing the flexible film to form an arc between its secured end and the convergence of the flexible film with the wet coating. The jaws also secure a flat plate which has a straight edge that deflects the arcuate portion of the flexible film toward the coating along a line extending transversely across the full width of the flexible film. The plate can be repositioned during the smoothing to adjust the radius of curvature of the arc in order to correct any defects that may appear in the smoothed coating. When the backing web is wide and is advanced at economically high speeds, the free end of the flexible film can be tensioned so that its trailing edge becomes bowed and in contact with the coating over its full width.
摘要翻译：可细的可磁化颗粒的湿式凹版涂层可以通过矩形的柔性膜来平滑，该柔性膜的一端固定在夹具的平的钳口中，以使其相对的端部能够自由地阻挡在涂层上，从而使柔性膜形成在其固定端与柔性膜与湿涂层的会聚之间形成弧形。夹爪还固定一个平板，该平板具有直的边缘，该柔性薄膜的弓形部分沿着横向穿过柔性薄膜的整个宽度延伸的线向着涂层偏转。在平滑过程中可以重新定位板，以调整弧的曲率半径，以便纠正平滑涂层中可能出现的任何缺陷。当背衬纤维网宽并且以经济高速度前进时，柔性膜的自由端可以被张紧，使得其后缘变得弯曲并且在其全宽度上与涂层接触。

摘要： A magnetizable layer can be applied to a flexible backing web by gravure coating at high speeds by independently driving the backing web at a speed that is substantially different from the surface speed of the gravure roll. Especially high coating speeds have been achieved when the gravure roll rotates oppositely to the direction in which the backing web is advancing. In one embodiment, a nip roll presses the backing web against the backup roll, there is a gap between the gravure roll and a backup roll, and an idler roll is positioned downstream of the gap to force the backing web into contact with the gravure roll over a short arc. When that backup roll has a hard surface such as metal, its surface can be machined with precision, and that precision can be maintained in spite of exposure to solvent vapors.
摘要翻译：通过以与凹版辊的表面速度基本上不同的速度独立地驱动背衬纤维网，可以通过高速凹版涂布将可磁化层施加到柔性背衬纤维网上。当凹版辊与背衬幅材向前移动的方向相反地旋转时，已经实现了特别高的涂布速度。在一个实施例中，夹辊将背衬纸幅压靠支撑辊，凹版辊与支承辊之间存在间隙，并且惰辊位于间隙的下游，以迫使背衬纸与凹版辊接触在短弧上。当该支撑辊具有诸如金属的硬表面时，其表面可以精确加工，并且即使暴露于溶剂蒸气也可以保持精度。
