Abstract
PURPOSE:To stop printing operation according to detection results by detection of a registering shear, by a method wherein a pair of left and right electrostatic sensor are provided in an impression cylinder, and a top position of a metal sheet which has been carried between a blanket cylinder and the impression cylinder to be pinched between the impression cylinder and the blanket cylinder is detected. CONSTITUTION:A top position of a metal sheet made stationary with front gauge mechanisms 34a, ...34n is detected with a pair of microsensors 36a, 36b established at left and right symmetry positions with respect to a carrying direction. An angle sensor setting switch 62 sets a detection phase angle during a period while grip pawls 32a, ...32n grip the metal sheet in one rotation cycle of an impression cylinder 30. When output of an angle sensor 58 conforms to this angle, a comparator 70 judges whether each of output digital data of the displacement sensors 36a, 36b, which is output of an A/D converter 68, is within a set range of an upper and lower limit setting switch 60. Registering shear can be predicted thereby. A sensor for detection of passing of the metal sheet is provided to a delivery part, and the registering shear is detected only when the sensor outputs. When the registerring shear is detected, processes such as impression throwoff, delivery of paper, etc., are performed.
