Abstract: A tool-holder column for a unit for converting a flat substrate that has two upper bearings (14, 16) each for supporting one end of an upper rotary tool (10), and two lower bearings (15, 17) each for supporting one end of a lower rotary tool (11), the flat substrate being movable longitudinally between the upper rotary tool (10) and the lower rotary tool (11), the bearings (14, 15, 16, 17) being vertically movable in opposite directions on either side of the longitudinal direction (L) of movement of the flat substrate, and a common drive for the bearings (14, 15, 16, 17) allowing the bearings (14, 15, 16, 17) to be moved simultaneously by one and the same distance in opposite directions, and including a screw device (25), the bearings (14, 15, 16, 17) being mounted one above another on the screw device (25) such that the rotation of the screw device (25) causes the linear movement of the bearings (14, 15, 16, 17) in opposite directions.

Abstract: A rotary-tool mandrel for a unit for converting a flat substrate, on which a sleeve (13) is intended to be fitted, the mandrel includes a cylindrical core (14), a peripheral wall (17) that is able to take up a rest position and a locking position by exerting a radial pressure on the sleeve (13) in order to lock it in position on the mandrel (12), a pressure fluid circuit (21) provided between the peripheral wall (17) and the cylindrical core (14) for exerting the radial pressure on the sleeve (13), and a cooling fluid circuit (24) for allowing a fluid to flow in the region of the cylindrical core (14) and for cooling the mandrel (12).

Abstract: A method for converting a flat substrate (W) in a station (3) for converting a flat substrate (W) that includes a rotary cutting unit (9) and at least one rotary deformation unit (7, 8) positioned upstream of the rotary cutting unit (9) in the direction of movement (L) of the flat substrate (W), the method including: determining the conversion parameters of the flat substrate (W), such as the deformation layout and cutting layout; choosing a sleeve (13) carrying a form for carrying out the deformation depending on the deformation layout; mounting the sleeve (13) on a mandrel (12) in the rotary deformation unit (7, 8); choosing the cutting tools (91, 92) depending on the cutting layout; mounting the cutting tools (91, 92) in the rotary cutting unit (9); and starting the conversion of the flat substrate (W).
