    • A method of applying a material to a moving substrate is disclosed. The method includes providing a die comprising a die body having a cavity therein, wherein the cavity is in fluid communication with an applicator slot. The die is then oriented such that the applicator slot is positioned so as to dispense the material onto the substrate. The material is introduced into the die cavity such that the material is dispensed onto the substrate through the applicator slot. At least one end of the slot includes means for preventing lateral widening of the dispensed material. In another embodiment, means will be disposed at both ends of the applicator slot. The method is particularly useful when the capillary number characteristic of the coating process is less than 0.5
    • 公开了一种将材料施加到移动的衬底上的方法。 该方法包括提供一种模具,其包括在其中具有空腔的模具主体,其中所述空腔与施加器槽流体连通。 然后将模具定向成使得施加器狭槽定位成将材料分配到基底上。 将材料引入模腔中,使得材料通过施加器槽分配到基底上。 槽的至少一端包括用于防止分配材料的横向加宽的装置。 在另一个实施例中,装置将设置在施放器狭槽的两端。 当涂布过程的毛细管数特性小于0.5时,该方法特别有用
