Abstract:
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).
