Abstract
The present invention relates generally to the manufacture of oil filters. The present invention provides a channel roll with a unique design that minimizes the channel roll surface contact with oil filter media. The design includes the formation of ridges projecting from the surface of the channel roll of such a design that is sufficient to control movement of the roll of oil media into the oil media pleating process, yet greatly reduce the surface contact with the oil media.
