An abutment (6) is provided at the joint between the metal sheets (4, 5) and extends, in an active position, up over the tables (2, 3) so as to serve as an arrest on insertion of the sheets (4, 5). The abutment (6) is lowerable to a passive position. The tables (2, 3) are movable towards and away from one another in a relative advancement movement, and the clamping jaws (7, 8) are suspended in parallelogram guides (16, 17; 22, 23) so that they are movable towards and away from the tables (2, 3). At least the one parallelogram guide has an anchorage (14) in the frame (1) of the machine so that the associated clamping jaw (8) can accompany the advancement movement. |
