| 摘要 |
The invention concerns a machine comprising driving means ( 14, 16, 18 ) for driving sheets in a drive direction (F) through a processing zone (T), and processing means including a tool ( 53, 53' ) and a counter tool ( 56 ), respectively, borne by a first and by a second transverse rotary support shaft ( 52, 54 ). Said processing means are designed to produce in the sheets cutouts and folds transverse to their drive direction. The counter tool has a substantially cylindrical surface having at least one working strip ( 57 ) which extends parallel to the axis of the second support shaft and is radially offset relative to the portions ( 58 ) of said surface which are adjacent to said strip, the latter being designed to cooperate with the tool to form a cutout or a fold in a sheet.
