The work is aimed at modeling the control system of a slitting machine of a paper machine in order to improve the quality of products and eliminate defects in winding density. The developed automated system implements the functions of controlling the operating modes of the machine, distributing the loads of the bearing shafts, braking the roll and tensioning the paper web.

To solve the problem with a large time delay in combined control systems, it is proposed to introduce an additional control circuit for the speed of paper pulp intake. The introduced circuit will function alternately with the current pressure control circuit inside the pressure device.

Keywords: Paper-making machine, pressure device, paper mass intake, paper web weight, computer modeling, regulator.

The article is devoted to solving the current problem - improving the environmental safety of cities by using the specific functions of green plantations in the formation of the green frame belt. Analysis of advantages and disadvantages of existing methodological approaches to formation of "green frames" of cities allowed to systematize, select and scientifically justify estimated criteria taking into account climatic conditions, landscape, impact of anthropogenic factors, efficiency of creation of comfortable habitat and to develop methodology of formation and selection of "green frame" belt of cities.
