Method for recognizing sheet incoming into pusher machine on presence of double or multiple sheets, involves determining thickness of sheet incoming into pusher machine by groped working sensor

摘要

The method involves determining thickness of a sheet (91) incoming into a pusher machine by a groped working sensor and a contactless working electronic sensor during start of a printing order. The determined value is compared with a job-specific desired value for recognizing double or multiple sheets. An independent claim is included for a device for recognizing sheet incoming into a pusher machine on the presence of double or multiple sheets.
