1. A system of manufacturing a filter cartridge comprising:

  • a tube of laminated and seamed filter media;

    a media unwind mechanism, the tube of laminated and seamed filter media being operatively positioning on the media unwind mechanism;

    a mandrel having a cone-shaped starting point operatively positioned proximate the media unwind mechanism;

    structure, operatively positioned proximate the mandrel, for feeding the tube of laminated and seamed filter media into the cone-shaped starting point of the mandrel;

    structure, operatively positioned proximate the mandrel, for pressurizing the tube of laminated and seamed filter media with a gas;

    a pleater mechanism, operatively positioned proximate the mandrel;

    a blade mechanism having at least two pleating blade mechanisms, each pleating blade mechanism comprising three (3) pleating blades, operatively associated with the pleater mechanism, for alternately engaging the tube of laminated and seamed filter media with the at least two pleating blade mechanisms in a filter media pleat forming area;

    structure, operatively positioned proximate the pleater mechanism, for moving newly formed pleated filter media downstream; and

    structure for compressing the tube of laminated and seamed filter media radially toward the mandrel.
