Abstract
Apparatus and method related to a cartridge filter having self-regulated pleat spacing. An elastic adhesive bead is used on an outer surface of a cylindrically formed pleated filter media to maintain pleat spacing without damaging the pleats or the filter media. In this way, a cylindrical pleated filter media may be formed from a planar filter media without the need for manually spacing the pleats during or after formation into a cylinder.
