Abstract: A method for generating decks of sheet elements (18) comprises the steps of positioning a set of numerous sheet elements (18) onto a transport surface of a transport device (30) to partly overlap in transport direction (T). The set of overlapping sheet elements (18) is moved against a stop member (44). The stop member (44) is moved in the transport direction (T) with a lower velocity than a velocity of the transport surface. By maintaining displacement of sheet elements (18) which are not yet contacting stop member (44) all sheet elements are shifted towards stop member (44) to define a deck. The method is carried out by a corresponding device.

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 stacking device for generating decks (10) of sheet elements (12) comprises a transport device with an upper side onto which sheet elements (12) are arranged on separate sheet sections (50). Each sheet section (50) is adapted to transport at least one sheet element (12). The upper side has a height offset between adjacent sheet sections (50). A displacement element shifts sheet elements (12) of one sheet section (50) onto an adjacent sheet section (50) in order to produce the deck (10) of sheet elements (12).

Abstract: This invention discloses a very compact play-free bearing unit. The bearing runs without play while having a reasonably large play when assembling and disassembly the bearing unit from its axle. The bearing unit uses three bearings, one of which is mobile, and thanks to a preloading mechanism the play is removed when loaded. Thanks to an amplification lever, the preloading unit is able to function either with a pneumatic actuator or with a hydraulic actuator.

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).
