Tambov, TSTU, 2005. - 128 s. The main technological and structural aspects of the design of roll machines for processing polymeric and other materials are considered . Particular attention is paid to the modeling of the plasticization process on rolls and calenders, as well as strength calculations of their main parts. Engineering methods of optimal design for solving problems of minimization of technological power and mass of working bodies are given while ensuring the condition of strength of the main parts . It is intended for postgraduates, undergraduates and senior students of the specialty 240801 in the implementation of course and diploma projects for the development of roll equipment for the processing of polymer materials .
