Abstract (en)
[origin: US4530283A] The turning cylinder and storage cylinder in a perfecting printing press is provided with changeover mechanisms having spring-loaded electromagnetically releasable latches and sensors for detecting latched adjustments. Moreover, a contactless sensor is provided for detecting clamping of the calendering suckers in the storage cylinder even when the cylinder is rotating. Contactless proximity switches determine the correct phase adjustments between the storage cylinder and the turning cylinder for both perfecting and first form printing. An access door and interlock guarantees that the cylinders are turned to a normal position and braked before the access door is opened, and the access door cannot be closed for subsequent printing until changeover has been completed. An indicator array indicates the sequence of adjustments to follow and abnormal conditions.
