Knysh O. Methodological Foundations of Quality Assurance of the Perfect Binding of Book Products

Dissertation is devoted to solving the actual scientific and applied problem of the quality assurance of the perfect binding of book products based on theoretical and experimental impact researches of geometrical, kinematical, kinetostatic parameters of development of new devices and means for book block spine processing; transportation systems; technological modes that provide improving the strength and durability of perfect binding, reducing the energy consumption of the technological process. The method of spine folds cutting by disc cutting knives with bilateral planetary drive has been improved. For this purpose, the method of the unilateral planetary drive of cutting discs and the immovable counter blade has been developed. It has developed mathematical models and conducted the analytical research of the method's geometrical, kinematical, kinetostatic parameters. The new method of unstoppable cutting of book blocks by plate screw knife has been proposed. It has been researched geometrical, kinematical, kinetostatic parameters of the corresponding device. The optimal geometrical parameters of the plate screw knife have been estab- lished, in terms of loads decrease and ensuring the required quality of the cut plane. Geometrical parameters of programmed book block spine surface, technological regimes for quality assurance of perfect binding have been optimized. It has been created recommendations for the improvement of technological processes with an aim to improve the quality of the perfect binding of book products.
