Abstract (en)
[origin: EP2705914A1] The device has a complementary guide unit including a part (5) integral of a punch holder (3) and another part (6) integral of a lower frame (2). The punch holder slides between an inactive position and a working position relative to a sheet part. The sliding motion of the holder is controlled by displacement of an upper frame towards the lower frame. The latter part is movable between an active position in which the latter part is engaged relative to the former part and the inactive position, where the former and the latter parts are free from each other.
