Abstract: A cutting arrangement comprises a blade shaft (32) which is mounted for drivable rotation about a blade-shaft axis of rotation (31) and which has at least one circular blade (34); and a brush roll (16) which is disposed opposite the blade shaft (32) and mounted for rotation about a brush-roll axis of rotation (15); the brush roll (16) possessing shells (37) in the cross-sectional shape of a segment of a circle which are disposed on a roll core (17) and which have an outside (39) and an inside (40) that is turned towards the roll core (17), bristles that stand out from the outside (39), torque-transmission components (44, 45, 46) for transmitting torque from the roll core (17) to the shells (37), and fastening components (49, 51) for fixing the shells (37) to the roll core (17).

Abstract: The invention relates to a corrugated cardboard processing device comprising at least one tool carrier which is displaceably mounted transversely with respect to a transport direction of a corrugated cardboard web along at least one guide element, and a lubricating device for lubricating a bearing between the at least one tool carrier and the at least one guide element.

Abstract: A conveyor unit for conveying a web of material, in particular for conveying a web of corrugated board in a corrugating machine, comprises a machine frame; a delivery roller, which is lodged in the machine frame rotatably about a first axis of rotation; a drive for actuation of the delivery roller; a draw roller, which is lodged in the machine frame rotatably about a second axis of rotation, the first axis of rotation and the second axis of rotation being substantially parallel to each other, a nip for the web of material to pass through being formed between the delivery roller and the draw roller, the draw roller having a draw-roller-surface coefficient of friction which is selected so as to ensure power transmission from the draw roller to the web of material that rests thereon, and the delivery roller having a delivery-roller-surface coefficient of friction which is less than or equal to the draw-roller-surface coefficient of friction; and a torque transmission arrangement, which acts between the delivery

Abstract: On a machine frame, a machine for the lengthwise treatment of webs of corrugated board comprises a pair of tool beds, on which several tool holders are disposed for displacement by means of a threaded spindle. The tool holders each support a tool. The number of tool holders exceeds the number of threaded spindles. Each tool holder has a spindle nut, which is disposed on the threaded spindle and is mounted rotatably in the tool holder. It can be non-rotatably coupled with the tool holder by means of a clutch.

Abstract: A deskewing device for a moving web of material in a corrugated cardboard manufacturing system incorporates a plurality of successive processing units that are equipped with processing tools, which are movable crosswise to the direction of conveyance of the web of material. A skew measuring device is provided to determine the skew of the web of material. It has a first position sensor, at least one second position sensor, which determine the transverse position of the web of material at predetermined longitudinal positions. A control unit is used to calculate from the data of the position sensors the skew of the web of material and the transverse position of the processing tools is corrected accordingly.

Abstract: An apparatus for the manufacture of sheets of corrugated web of variable size comprises a margin cutting arrangement, which is disposed--in the conveying direction--downstream of, and separated from, longitudinal cutting arrangements and which is provided with cutting devices for cutting margins, which are permanently in engagement with the web of corrugated board. In the case of changes of format width accompanied by changes of the width of the margins to be cut off, this makes it possible that the latter can be cut continuously, which helps avoid malfunction.

Abstract: An apparatus for the manufacture of sheets of corrugated board of variable size comprises a cross cutter for severing the entire web of corrugated board disposed, in the conveying direction of a web of corrugated board, downstream of at least one longitudinal cutting arrangement, of cutting devices for cutting lateral margins and of discharge devices for the margins cut off, and upstream of at least one cross cutting arrangement for cutting sheets of corrugated board.

Abstract: An apparatus for longitudinally slitting and/or grooving material sheets, particularly for sheets of corrugated board, which are being transported through the apparatus. The apparatus includes a plurality of tool members positioned in rows on opposing sheet sides which cooperate in opposing pairs. Each set of rows includes a drive shaft and an adjusting spindle in operable communication with the tool members which include tool body members and which can be conducted within the apparatus along guide rails and can be coupled through controllable couplings to the adjusting spindles. Each tool body member also includes a plurality of tool members where at least one of the tool body members and guide rails are adjustable within the apparatus to position the opposing pair of tool members in the operating positions in engagement with the sheet.
