Ooops. Here they are:

The filter bags are open on the top and closed on the bottom. The bottom can be closed in various ways --tied-off, with metal clamps, with folds sewn flat, inserting a bottom circle or other methods. The stop of the filter bag is not star-shaped but cylindrical, meaning that it is finished off, as desired, as conventional filter elements, with snap band rings with double-beaded gasketing, felt strips, rings or other conventional installation methods. The open top can therefore be made to fit any standard cell plate and gasketing size. The filter material applicable is many fold and may be needled felt, non-woven, woven material, warp-knitted, circular-knitted fabric also out of micro-filament yarn, fiberglass and/or metal fabrics. The length and diameter of the filter bag is variable in accordance with the needs in line with the filter housing dimensions.

According to another form of the present invention, after the adhesive is applied to the side edges of the filter material, a strip of material is applied along the length of the adhesive before the adhesive is cured. The strip is visible along the exterior of the filter element and can be marked with the selecting and identifying information, such as by applying a color to the strip, or by marking the strip with alpha-numeric characters corresponding to functional and structural characteristics for the filter element. The strip is preferably formed of a mesh-type material which allows the liquid adhesive to wick through the strip and form an exterior seal or barrier. When the adhesive is cured, the exterior seal or barrier prevents the color and/or alpha-numeric characters on the strip from being worn-off or degraded during use.

This has got to be a typo...I thought of "fabric wick", but not sure. It could just be a "strip". Anyway, here are some refs, but I'd get back to the author/client.
