Abstract
A filter element, as in a filter bag, comprises a pocket having partitions between the side walls to form pocket portions. The margins of the partitions are welded ultrasonically to the inner surface of the layers. The inlet end of the partitions may be split into flaps to ease connection of the bag to a header frame. A simple yet effective method and apparatus may be utilizable to make the filter element, and a bag including it.
