IPC: B41F31/30
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To improve a printing quality by upgrading an operability and an operating efficiency in a rotary press. SOLUTION: A distance sensor 20 set in its detecting direction to an axially central direction of an inking roller 5 is fixed to a bearing lever 7 via a bracket 21. After a collapsing width N of the roller 5 is set to a value suitable for printing, a distance from the sensor 20 at that time to a surface of the roller 5 is stored as a reference value y0. After printing is started, a difference αbetween the distance (y) from the sensor 20 to the surface of the roller 5 and the value y0 is obtained at each preset time. When the roller 5 is expanded so that the difference α exceeds a preset value, a pulse motor 26 is rotated, the roller 5 is separated from a surface of a plate cylinder 6 by the difference to set the width N to a suitable width. Then, the distance (y) at that time is set as a new reference value y0.  Since a regulation of the width N for maintaining a printing quality can be conducted during printing without hand, operability and operating efficiency can be improved.
