Abstract: A bearing for holding a rotary conversion tool (10, 11) that includes two end rolling bearing devices (26, 28), at least one intermediate rolling bearing device (27) interposed between the end rolling bearing devices (26, 28), the end and intermediate rolling bearing devices (26, 27, 28) being intended to engage with an end (10a, 10b, 11a, 11b) of the rotary tool (10, 11), and at least one mechanical actuator (32, 33) configured to exert a radial preload force (Fo, Fo′) at the intermediate rolling bearing device (27).

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 sleeve extractor for a unit for converting a flat substrate that includes a base (23) intended to be fixed to the conversion unit (7) and an extraction head (24) that: a) is movable with respect to the base (23) between a withdrawn position and a deployed position and, b) has a gripper (25) that can engage with a sleeve (13) of a rotary tool (10, 11).
