In the production of hinge-lid packs with especially rounded longitudinally edges (11, 12) a blank (14) is pre-shaped in the region of a shaping station (18). To this end, the regions of the longitudinal edges (11, 12) of the blank (14) are pressed against shaping margins (23, 24) of a shaping plate (20) by shaping rollers (21, 22). To increase the performance of the shaping station (18), the shaping rollers (21, 22) are moved back into the starting position along a path of movement (29) which is located at a distance from the shaping plate (20). During this movement back into the starting position, the pre-shaped blank (14) can be discharged and a following blank can be moved into position.
