Abstract
Stepwise feed apparatus for longitudinal advancement of photographic print or film strips to an operating device, such as a cutter. Control of step feed distance is provided by a digital command derived by selective positioning of a movable cursor relative to the operating device, the cursor being set visually so as to coincide with a selected operating point along the strip. The command distance may be corrected at will either with the strip at rest or when in motion to accommodate changes in the interval between operating points along the strip.
