    Abstract: Ribs are formed on a nonwoven mat to produce a battery separator. The ribs are formed by extruding a foamed polymer onto the nonwoven mat by extruding the foamed polymer through a multihole die as the nonwoven mat follows an arc passing over a mat backup plate. After the ribs have been extruded and the foamed polymer is still soft, the nonwoven mat with the extruded ribs may be passed through a fixed gap such as a pair of calendar rolls to produce a battery separator of uniform thickness.

    Abstract translation: 肋形成在非织造垫上以产生电池隔膜。 这些肋是通过将泡沫聚合物挤压在非织造垫上而形成的,因为非织造垫通过垫子支撑板的弧线挤压发泡聚合物通过多孔模头。 在已经挤出肋并且发泡聚合物仍然柔软之后,具有挤出肋的非织造垫可以通过诸如一对压延辊的固定间隙,以产生均匀厚度的电池隔板。
