Abstract
Apparatus for subdividing webs of photographic paper into discrete prints has a detector which scans marks applied to the web for the purpose of arresting the drive for the web at the exact moment when the central portion of a frame line between two successive images on the web is in register with the knives. The signals which are furnished by the detector can be used to arrest the drive only within a short interval of time which begins shortly or immediately before a mark reaches the detector. This prevents the detector from arresting the drive in response to detection of a flaw or a particle of foreign matter whose effect upon the detector is similar to that of a mark.
