A selection plate ( 39 ) is provided on a punch device ( 1 ) for activating or deactivating individual punch holding bars ( 13, 14 ). The plate has a coupling device ( 40 ) associated with a positive-locking coupling between a punch holding bar ( 13, 14 ) and the selection plate ( 39 ). Associated with the positive-locking coupling is an edge of the selection plate ( 39 ), that is provided with a recess ( 42 ), an extension ( 43 ) of the punch holding bar ( 13, 14 ) that extends around said edge, and/or a rib ( 41 ), which is located on the underside of the selection plate ( 39 ) and is associated with the punch holding bar ( 13, 14 ). As a result, it is possible to selectively establish or eliminate a positive-locking connection between the punch holding bar ( 13, 14 ) and the selection plate ( 39 ). Via the rib ( 41 ), the punch stroke of the selection plate ( 39 ) is merely transmitted to the punch holding bar ( 13 or 14 ), which is in positive-locking engagement with the lateral edge or the projections of the selection plate ( 39 ). The elongated rib ( 41 ) covers the heads ( 26, 27, 28, 29 ) of the punches ( 8 ) and transmits the stroke in a planar manner to the punch holding bar ( 13 or 14 ).
