    • An apparatus for dispensing a fluid onto a moving substrate is disclosed. In one embodiment, the apparatus is 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 fluid onto the moving substrate. The fluid is introduced into the die cavity such that the fluid is dispensed onto the moving substrate through the applicator slot. At least one end of the slot includes means for preventing lateral widening of the dispensed fluid. In another embodiment, means are disposed at both ends of the applicator slot. The apparatus is particularly useful when the capillary number characteristic for dispensing the fluid onto the moving substrate is less than 0.5.
    • 公开了一种用于将流体分配到移动的衬底上的装置。 在一个实施例中,该装置是包括其中具有空腔的模具主体的模具,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被定位成将流体分配到移动的基板上。 将流体引入模腔中,使得流体通过施加器槽分配到移动的基底上。 槽的至少一端包括用于防止所分配流体的横向加宽的装置。 在另一个实施例中,装置设置在施放器狭槽的两端。 当用于将流体分配到移动的衬底上的毛细管数特性小于0.5时,该装置特别有用。
