The paper stop allows paper, laminated cards, loose leaf collections, brochures or documents to be placed on a straight edge and thanks to the adjustable side stop, the product to be punched can be precisely centred. This way, when using the appropriate punching knife, round holes, thumb slots or calendar punchings are created.
For the production of thumbholes or semicircular punched holes in calendars, in order to be able to turn the pages neatly even with the calendar hanger bound in the ring binding, the thumbhole punching knife D21 is also required.
For central round holes, which are used for hanging up wall calendars, the round hole punching knife D6 is also required.
