Abstract
An apparatus is provided for effecting the formation of a packaged food product with the food being contained within a receptacle having a cover adhered to the receptacle. Prior to securing the cover to the receptacle, the surface that is to be sealed to the cover is cleaned by wiping with towel material. The towel material is advanced from a supply to a cleaning position to wipe a cover engaging surface to remove at least a portion of contaminants or foreign material present on the container, thereby improving adhesion of the cover to the receptacle. Towel material can be advanced from time to time from the supply to a take-up mechanism to present clean or fresh towel material at predetermined intervals. A method for cleaning container-sealing surfaces is also provided.
