TYMPAN OF VIBRATING ROLLER, PRINTING APPARATUSES OF PRINTING MACHINE

摘要

FIELD: tympan of vibrating roller, printing apparatuses of printing machine. ^ SUBSTANCE: tympan on lateral surface of roller, for example roller of printing apparatus has elastic and(or) compressible layer whose contact stress P depends upon value of depression. Said layer is formed in such a way that to provide relationship of contact stress from depression value grown up to 700 N/cm2 at least in separate zones. ^ EFFECT: possibility for providing by simple means high quality of printed products due to lowered response to vibration and to distortion of printing process. ^ 46 cl, 8 dwg
