摘要： A method for dispensing a foamed material onto a substrate surface, comprising the steps: generating a relative movement between the substrate surface to be coated and an exit opening of a material dispensing apparatus, mixing at least two material components in a mixing device to provide a free-flowing, foamable dispensing material, generating a pressure differential between the mixing device and the dispensing region located downstream in the direction of flow from a discharge cross-section of the exit opening, conveying the dispensing material from the mixing device for the dispensing material to the exit opening, and discharging the dispensing material from the exit opening onto the substrate surface. The invention proposes that the dispensing material be kept under such a pressure in the adjacent region upstream from the discharge cross-section of the exit opening that the dispensing material in this region has a foaming rate that is less than 10% of the foaming rate which ensues at the end of the foaming process.

摘要翻译： 一种用于将泡沫材料分配到基材表面上的方法，包括以下步骤：在待涂布的基底表面和材料分配装置的出口之间产生相对运动，在混合装置中混合至少两种材料组分以提供 自由流动的可发泡的分配材料，在混合装置和位于沿着出口开口的排出横截面的流动方向下游的分配区域之间产生压力差，从分配材料的混合装置输送分配材料 并且将分配材料从出口开口排出到基板表面上。 本发明提出，分配材料在出口开口的排出横截面上游的相邻区域中保持在这样的压力下，该区域中的分配材料的发泡速率小于发泡速率的10％ 在发泡过程结束时发生。
