Flat die-cutting is the primary method of producing folding-carton packaging: a flat die (form) cuts, creases, and cold-embosses the cardboard blank in a single stroke. This invention concerns the construction of the flat die-cutting die itself. The arrangement of its cutting and creasing rules and of the plywood base is designed to raise the accuracy and stability of cutting, creasing, and embossing of sheet cardboard, to keep the rules rigidly positioned under load, and to simplify the removal of finished blanks. The result is higher quality and repeatability of the die-cut carton blanks.

The press is the section of a die-cutting machine that drives the movable pressure plate against the die to cut and crease the cardboard. This invention improves the pressure-plate drive so that it delivers a large, uniform cutting force while reducing the inertial loading that arises when the plate reverses at high cyclicity. By stabilising the plate’s motion through the working cycle, the drive lowers dynamic loads on the machine, increases productivity, and improves the quality and consistency of cardboard die-cutting.

This Ukrainian invention application concerns a press for an automatic die-cutting machine. It was filed on 24 March 2025 and its bibliographic data were published on 8 October 2025. The public NIPO record currently contains no published formula, description, abstract, or drawing, so the accompanying portfolio visual is explicitly presented as schematic research context rather than an official application figure.

This invention concerns the pressure-plate drive of a die-cutting machine press based on wedging mechanisms. The wedging arrangement is designed to deliver the large, uniform force needed to cut and crease cardboard while limiting the inertial loads that occur at plate reversal. Smoothing the plate’s motion reduces impact on the die and the machine and improves the stability and quality of the die-cutting process.

This invention improves the pressure-plate drive of a die-cutting machine press by combining wedging mechanisms with additional links. The combined mechanism smooths the motion of the pressure plate and improves the uniformity of its contact with the cardboard sheet during cutting, creasing, and embossing. The result is more even loading of the die, reduced dynamic loads, and better repeatability of the die-cut blanks.

This invention concerns a combined drive of the pressure plate in a die-cutting machine press. The combined mechanism increases the dwell of the plate during the cutting phase, so the cutting force is applied more fully and evenly, while reducing the power loading on the drive. This raises the productivity and cut quality of the press and lowers the mechanical stresses in the drive.

This invention concerns a wedging drive of the pressure plate of a die-cutting machine press, arranged to improve the stability and repeatability of the plate’s motion throughout the working cycle. A stable, well-controlled plate stroke ensures consistent cutting and creasing of the cardboard, reduces impact loads, and supports reliable operation at high cyclicity.

This invention is a device for manufacturing cardboard packaging blanks that integrates the cutting, creasing, and separation of the blanks within a single unit. By coordinating these operations, the device raises the quality and productivity of carton-blank production and reduces the manual handling required between operations. It is intended for the automated production lines used in folding-carton manufacture.

This invention concerns an upgraded pressure-plate drive for a die-cutting machine press. The drive is designed to lower the inertial loading of the plate and to distribute the cutting force more evenly across it, so that the cardboard is cut and creased uniformly over the full format. The improvement increases cut quality and reduces the dynamic loads carried by the press mechanism.

This utility model concerns a die-cutting machine press with a modified pressure-plate drive based on coupled crank-crosshead contours. The coupling synchronises the motion of the plate so that the cutting force is applied more evenly than with a conventional single-contour drive. The solution improves the uniformity of cardboard cutting and is one of an early series of improvements to flat die-cutting press drives.

This utility model concerns a die-cutting machine press with an improved lower pressure-plate drive. The drive geometry is arranged to increase the uniformity of the cutting force delivered by the plate, improving the quality of the die-cut cardboard blanks. It forms part of the early development of the pressure-plate drive mechanisms studied in this line of research.

This invention concerns a die-cutting machine press with a drive mechanism of the pressure plate developed to improve the quality of cardboard die-cutting. The mechanism shapes the plate’s motion so that the cutting and creasing forces are applied more evenly across the format. This press served as prototype technology and is referenced in later academic literature, dissertations, and subsequent patents in the same research line.
