A stripping apparatus includes a pair of first and second base plates which are disposed in facing relationship to each other in a vertical direction and movable toward and away from each other. The first and second base plates include first support holes and second support holes, respectively, disposed in alignment with each other in the vertical direction. A plurality of pressing pins are insertable into the first and second support holes. A fixing device is provided on each of the first and second base plates for releasably fixing the pressing pins inserted into the first and second support holes. A blank and a waste of a paperboard are separated through abutment of the pressing pins fixed within the first support holes of the first base plate in the area corresponding to the blank and through abutment of the pressing pins fixed within the second support holes of the second base plate in the area corresponding to the waste when the first and second base plates are move toward each other with the paperboard interposed therebetween.
