Abstract
An apparatus for stripping an adherent cover sheet from a photosensitive film sandwich. A leader from a roll extends over a film having a cover sheet and is attached to an edge of the cover sheet. When the roll is driven, the leader wraps on it and strips the cover sheet from the film which had previously been fixed in a stationary position.
