    Abstract: A tool clamping assembly (38) for clamping a blanking tool (40) intended to be used in a blanking station of a sheet processing machine has a frame (46) to which the blanking tool (40) is to be clamped and at least one clamping element (48). The frame (46) has an aligning mechanism adapted for aligning the blanking tool (40) in a first direction. Further, the frame (40) has at least one support surface (60) oriented to support the blanking tool (40) in a second direction which is perpendicular to the first direction, and at least one abutment surface (62) oriented to support the blanking tool (40) in a third direction which is perpendicular to the first and second directions. The clamping element (48) is displaceable between an open position and a clamping position, the clamping element (48) being adapted for clamping the blanking tool (40) against both the support surface (60) and the abutment surface (62). Further, a blanking tool assembly with such a tool clamping assembly is shown.

    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: Bearing unit, in particular for rotary processing tool. 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 includes a first bearing group with two outer bearings (12) and a second bearing group with an intermediate bearing (14). One of the bearing groups (12, 14) is mobile and can be displaced radially by a preloading unit to remove play when activated. Thanks to an amplification lever (20), the preloading unit is able to function either with a pneumatic actuator or with a hydraulic actuator.

    Abstract: The invention relates to a method for checking the quality of a product (1) comprising at least two cardboard portions (2) connected to each other such that a slot (10) extends between the cardboard portions from one side of the product (1) to the opposite side, with the slot (10) being expected to extend perpendicularly with respect to an outer edge of the product (1), comprising the steps of: - capturing a 2D image of the slot (10) at one side of the product (1) and of the slot at the opposite side of the product, - analyzing the images so as to recognize the slot (10), - comparing the positions of the slot of one product at the opposite sides, - making a determination whether or not a difference between the positions is within a predefined range of tolerance. The invention further relates to a machine for checking the quality of a product (1) made from at least two cardboard portions (2) connected to each other such that a slot (10) extends from one side of the product to the opposite side, with the slot being expected to extend perpendicularly with respect to an outer edge of the product, the machine comprising two cameras (304) adapted for capturing a 2D image in a stacking area for stacking the products, an image processing module (306) adapted for recognizing in the captured images the position of the slot on the two sides of the product, and an offset determination module (310) adapted for determining the amount of offset between the position of the slots at the opposite sides of the product.
