This article describes a specialised computer-aided design program for studying the mechanisms of printing and packaging machines. The software allows a mechanism to be constructed visually, animated, and analysed for its kinematic parameters, and it generates 3D models that can be exported to other CAD systems. By combining synthesis, visualisation, and analysis in one environment, the tool accelerates the early design of linkage mechanisms.

This paper presents a methodology for exporting data, visualising mechanisms, and generating their 3D models within a specialised computer-aided-design environment. It describes how a mechanism defined in the program is converted into engineering documentation and into 3D geometry for other CAD systems, including automated generation via AutoLISP. The methodology links mechanism analysis with downstream design and modelling work.

This paper analyses the software available for the research of the mechanisms of printing and packaging machines. Existing programs for mechanism synthesis, kinematic analysis, and visualisation are compared by their capabilities and limitations, and the requirements for a specialised research tool are formulated. The analysis motivates the author’s own software for the construction and kinematic analysis of machine mechanisms.

This paper presents a software system for the automated kinematic analysis of lever (linkage) mechanisms with constant link lengths, developed in Embarcadero RAD Studio. The system decomposes an arbitrary mechanism into structural (Assur) groups and computes the positions, velocities, and accelerations of the links across a full cycle. Results are presented as graphs and tables and can be exported for further engineering use. The tool automates routine kinematic calculations for the linkage mechanisms of printing and packaging machines.

This paper reports analytical research into the torques arising during the cutting of cardboard in a die-cutting press equipped with eccentrics in the pressure-plate drive. Experimental cutting data are interpreted analytically to describe how the resistance torque varies with the plate position throughout the cutting phase. The resulting dependencies link material resistance, plate kinematics, and drive loading, providing a basis for sizing the drive and predicting power demand. The findings improve the accuracy of engineering calculations for die-cutting equipment.

This conference paper provides the technical justification for a sectional construction of the pressure plate in a die-cutting press. It analyses the loads acting on the plate during cutting and shows how splitting the plate into sections reduces the peak drive force and the elastic deformation of the plate. The reasoning supports the transition from monoblock to sectional pressure plates in high-load die-cutting equipment.

This trade-journal article discusses the prospects of replacing the monoblock pressure plate of die-cutting equipment with a sectional one. Written for an engineering-practitioner audience, it explains how a sectional plate distributes the cutting load, lowers drive loading, and can improve the productivity and reliability of carton-packaging production. The article outlines the design considerations for moving from a monoblock to a sectional plate.

This article presents an innovative technical search for the design of the pressure-plate drive in a die-cutting press. It reviews the limitations of conventional drives and outlines wedging-mechanism-based concepts that smooth the plate’s motion and reduce inertial loads, aimed at improving the quality and stability of cardboard die-cutting. The article frames the direction of the author’s subsequent research and patents.

This paper experimentally evaluates how the speed regime of a die-cutting press affects the force loading of the combined pressure-plate drive mechanism during cardboard cutting. Measurements across a range of cyclic speeds relate the drive loading to the operating rate and to the resistance of the cardboard. The results quantify how higher cyclicity increases inertial loading and inform the selection of a working speed that balances productivity and drive load.

This paper reports an experimental evaluation of the loads in the combined drive mechanism of the pressure plate of a flat die-cutting press. A test setup measures the forces and torques acting on the drive during cardboard cutting, and the measured data are compared with analytical estimates. The study validates the load model of the combined mechanism and clarifies the conditions that govern its power demand.
