Abstract
When automatically winding a web of photographic paper or film fed from a feeding means such as a roller on a reel core, it is necessary to detect whether the web has been wound on the reel core or not in order to present jams and other inconveniences. The present invention achieves accurate detection of the web winding on the reel core by detecting a driving current of a motor which drives and revolves the reel core and comparing thus detected driving current with a reference value.
