  • Method and apparatus for corrugating filter media
    Patent number: 9463594
    Abstract: An apparatus for corrugating filter media includes upstream and downstream rollers. The upstream roller has an exterior surface including a corrugation pattern defining a plurality of circumferential channels. A heating source heats the filter media so that the filter media is within its elastic temperature range when the filter media engages the upstream roller. A motor drives rotation of the upstream and downstream rollers. A controller controls the motor so that the downstream roller rotates at a rotational speed greater than the upstream roller to impart tension to the filter media at the upstream roller. The heated filter media at least partially enters the channels of the corrugating pattern on the upstream roller to form corrugations on the filter media. A method of forming corrugations on filter media may be performed using the apparatus.
