摘要： In a printing press including an intaglio cylinder, an impression cylinder and a blanket cylinder, for the purpose of throwing on and off these cylinders there is provided a control apparatus comprising a first detection switch which produces a selection signal when a rotating radial projection passes by, and a plurality of second detection switches which generate timing signals when passing by a plurality of radially spaced projections. The selection signal is used to select either one of the second selection switches, and the timing signal generated by a selected second detection switch is used to throw on and off the cylinders.According to this invention it is not necessary to use a number of expensive multistage preset counters which are liable to misoperate due to noise.

摘要： Such defects as a folded back or bent portion and a notch along one or both side edges of a printing sheet is detected by a detector located on one or both sides of a front edge of a correctly fed printing sheet for detecting absence of the sheet and a timing signal generator which produces a timing signal while all length of the sheet passes by the detector. An output signal which stops printing operation is produced when the detector detects absence of the sheet while the timing signal is being produced. According to this invention it is possible to prevent formation of defective printed matter and damage of a printing press fed with defective printing sheets.
摘要翻译：通过位于正确供给的印刷纸的前边缘的一侧或两侧的检测器来检测诸如折叠部分或弯曲部分之间的缺陷以及沿着打印片的一个或两个侧边缘的凹口，用于检测不存在片材，定时信号发生器，其产生定时信号，同时纸张的所有长度都通过检测器。当检测器在产生定时信号时检测到纸张不存在时，产生停止打印操作的输出信号。根据本发明，可以防止印有缺陷的印刷品的印刷物的形成和印刷印刷纸的损坏。
