Abstract
A method and apparatus for continuous cleaning of bag making machinery is provided. A single roll with a cleaning material attached thereto contacts a rotating drum to remove debris from the surface thereof. When the portion of the cleaning material in contact with the drum becomes saturated with debris, the roll is rotated to present fresh cleaning material to the surface of the drum. The compact design of the cleaning apparatus permits its use in the limited space found around bag making machinery.
