摘要： The present invention relates to a filter element having a non-porous extrusion laminated strip formed on at least one edge and at least one side of a membrane. The strip is used to provide a means for ensuring a good bond between the filter element and the material into which it is potted. The strip is formed by the use of one or more extrusion heads that apply molten or softened polymer to one or both of the surfaces of the filter in a width and height desired. The strip is then subjected to pressure such as through a nip to at least partially embed the polymer strip into the filter pores so as to create a strong mechanical bond between the strip and the filter element. Additionally, it allows for the simultaneous formation of more than one membrane with the edge lamination at the same time.
摘要翻译： 本发明涉及一种在膜的至少一个边缘和至少一个侧面上形成无孔挤出层压条的过滤元件。 该条带用于提供一种用于确保过滤元件与其被封装到其中的材料之间的良好结合的装置。 通过使用一个或多个挤出头来形成条带，所述挤出头将熔融或软化的聚合物施加到所需的宽度和高度的过滤器的一个或两个表面上。 然后将带材经受压力，例如通过辊隙，至少部分地将聚合物条带嵌入过滤器孔中，以在条带和过滤元件之间产生强大的机械结合。 此外，它允许同时形成具有边缘层叠的多于一个的膜。
