ABSTRACT:
A punch apparatus is provided to punch holes in an article by the use of a die punch. The die punch is forced through the article to be punched. A cleaning device is extended into engagement with the die punch when the die punch is in a position penetrating the article. This enables a cleaning of the die punch. The cleaning device is then retracted so that the article can be detached from said die punch.
