    Abstract: The disclosure describes an arrangement which comprises a porous filter layer and a porous support layer. The porous support layer has first and second surfaces and the porous filter layer is positioned near the first surface of the porous support layer. The filter arrangement further comprises several polymeric beads disposed in parallel strips on the second surface of the porous support layer. The filter arrangement is corrugated to form pleats which extend generally perpendicular to the polymeric beads. Each pleat includes an open end, a bight end, and first and second opposing sides which extend between the open end and the bight end and include a portion within each pleat in which the opposing sides are in essentially parallel relationship. Each bead extends from the open end of the pleat along the first side to the bight end and from the bight end of the pleat along the second side to the open end. The portions of each bead which extend along the parallel portions of the opposing sides of the pleat are joined to one another.

    Abstract translation: 本公开描述了一种包括多孔过滤层和多孔支撑层的布置。 多孔支撑层具有第一表面和第二表面，并且多孔过滤层位于多孔支撑层的第一表面附近。 过滤器装置还包括在多孔支撑层的第二表面上平行设置的几个聚合物珠粒。 过滤器布置是波纹状的，以形成大致垂直于聚合物珠粒延伸的褶皱。 每个褶包括开口端，弯曲端以及在开口端和弯曲端之间延伸的第一和第二相对侧，并且包括在每个褶皱内的部分，其中相对侧基本上是平行的关系。 每个胎圈从皱褶的开口端沿着第一侧延伸到弯曲端，并且从皱褶的弯曲端沿着第二侧延伸到开口端。 沿着褶皱的相对侧的平行部分延伸的每个胎圈的部分彼此连接。
