METHOD FOR PRODUCING A CONNECTION INTERFACE IN A FILTER ELEMENT |
摘要 |
A method produces a connection interface in a tubular filter element for filtering liquids, including a filter mat ( 10 ). The opposite ends ( 14 ) of the filter mat are interconnected in a connection position by a planar weld seam ( 28 ) provided with an embossed strip in the region of the free ends ( 14 ) of the filter mat. A region is provided between the embossed weld seam ( 30 ) and the beginning of the transition towards the tubular filter mats, in which a smooth weld seam ( 32 ) is applied without embossing in a flat strip along the ends ( 14 ) of the filter mat. This arrangement enables the ends of the filter mat to be welded together in a strong and long-lasting manner. The embossed weld seam is simultaneously unloaded of any stress by the smooth weld seam. |
