    摘要: A roll of photographic film where a film strip is coiled about a spool with a film leader attached to the film strip. The film leader includes a tongue portion, a tear line defining a tear-out region in the tongue portion, and an adhesive which is applied to the tear-out region. The tear-out region is bonded to an underlying convolution of the film leader when the film leader is wound on said roll. When a user lifts the film leader from the roll, the tear line is ruptured allowing the tear-out region to remain affixed to the underlying convolution of the film leader. This, in turn yields a hole in the film leader which can be used to attach the film loader to a take-up spool within a camera.
