AI Technical Summary
Existing methods for forming features such as embossments or creases in filter media packs, such as those described in U.S. Pat. No. 6,780,217 and U.S. Pat. No. 7,122,068, require continuous processing using rotating rolls, which may not efficiently accommodate non-continuous or irregular shapes and lack flexibility in forming complex patterns.
A method involving creasing a filter media sheet, assembling pleat panels with a weld tool and anvil, and using ultrasonic vibration to weld the panels, allowing for the formation of pleated filter media packs with irregular shapes and complex patterns through linear reciprocating movements.
Enables the creation of pleated filter media packs with enhanced structural integrity and customizable features, such as irregular shapes and complex patterns, improving filtration efficiency and adaptability to various filter designs.
