摘要： 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.
摘要翻译：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。

摘要： A filter includes a pleated filter element having longitudinally extending pleats and a wrap member wrapped around the filter element. The wrap member is joined to the peaks of the pleats and has openings for increasing the dirt capacity of the filter. The filter element may be a composite of a filter layer, upstream and downstream support and drainage layers, a cushioning layer between the upstream support and drainage layer and the filter layer, and polymeric beads on the downstream side of the downstream support and drainage layer. An extruded polymeric mesh may comprise one or both of the upstream and downstream support and drainage layers.
摘要翻译：过滤器包括具有纵向延伸的褶皱的褶皱过滤器元件和围绕过滤元件缠绕的包裹件。包裹部件连接到褶皱的峰部，并且具有用于增加过滤器的污物能力的开口。过滤元件可以是过滤层，上游和下游支撑和排出层，上游支撑排水层和过滤层之间的缓冲层以及下游支撑和排水层下游侧的聚合物珠粒的复合材料。挤出的聚合物网可以包括上游和下游支撑和排出层中的一个或两个。
