    Abstract: A method and apparatus for forming a batt of particulate material which may be used in an absorbent article. The apparatus may include a vacuum zone, an air impermeable fence zone adjacent to the vacuum zone, and an air permeable fence zone adjacent to the vacuum zone. The air permeable fence zone may comprise an ambient air entry conduit in communication with an ambient air exit port. The method may include providing a laydown drum and a first web of material, positioning the first web of material substantially adjacent to the laydown drum, generating a vacuum through the laydown drum, depositing particulate matter onto the first web of material, and rotating the laydown drum.

    Abstract translation: 用于形成可用于吸收制品中的颗粒材料絮垫的方法和装置。 该设备可以包括真空区域,与真空区域相邻的不透气栅栏区域和与真空区域相邻的透气栅栏区域。 透气栅栏区可以包括与环境空气出口连通的环境空气进入导管。 该方法可以包括提供沉积鼓和第一材料网,将第一材料幅材基本上邻近沉积鼓定位,通过沉积鼓产生真空,将颗粒物质沉积到第一材料网上,以及旋转沉积 鼓。
