Abstract
A pocket filter cartridge for removing solid particulates from a dirty gas stream including a plurality of sheath-like filter bags suspended from a common header assembly in side-by-side relation. Each of the filter bags includes a plurality of alternating rows of filamentary stays or span stitching spaced across the width of the bag and extending generally parallel to one another along its length so that upon inflation of the bag by the dirty gas stream during use, the stays shape the bag into a plurality of adjacent tube-like sections opening into one another within the bag. The stays in each row are sized to be of a different length than the stays in the rows adjacent to it to alternately vary the thickness of the bag at the juncture of the tube-like sections formed in the bag.
