The Mathematical Model

For synchronization of sections of modern printing machines and equipment of such sections, driven by individual drives the system of “electronic shaft” is widely used. A development of the mathematical model of such a local drive, consisting of mechanical and electric-electronic parts as well as links between them, is provided. The model with an effective adaptive control block for increasing accuracy of the drive is provided in the form of a structural scheme. It, first of all, is usable for investigations of linear and nonlinear dynamic processes that take place in the mechanical part of the drive. Processes that take place in the electric drive are not detailed in this article. An example of the application of the model is provided.

Nonlinear Dynamic Processes

Near‐epoch dependence (NED) is a generalized dependence concept for functions of mixing processes. This chapter gives definitions and examples, and considers the application to nonlinear dynamic processes. The relation to mixingales is the key theoretical result. Results on the preservation of NED under various transformations and a special result for the adapted sequence case are considered next. Finally, the related concept of approximability is defined which, unlike NED, can hold in the absence of integer moments.

Printing Machine

A new type of inline coating system is designed and developed. The coating system can be mounted into printing press instead of blanket cleaner. An anilox roller and a sealed duct on the glazing oil transferring part for supplying and transferring the coating oil are introduced. A set of pressure adjusting mechanism is designed for changing the pressure between anilox roller and blanket cylinder, while a set of on-off impression mechanism is arranged to change the position of anilox roller and the on-off impression state. The press can print as normal when the coating system is dismounted. With this coating system, the press can coat prints with glazing oil. This system can be mounted in various type of printing machine. One new type of glazing technology named reverse coating can be achieved when it is mounted in multicolor press.
