Abstract
A manufacturing system and a method of producing a filter assembly for use in a filter is provided. The filter assembly includes a filter media, such as a pleated paper filter element, and opposing end discs secured to the filter media by a liquid bonding agent. The manufacturing system employs the method of dispensing the liquid bonding agent onto the end discs. Opposing ends of the filter media are inserted into the liquid bonding agent. The end discs are ultrasonically excited at one or more stations to heat the liquid bonding agent to a cure temperature.
