Method of and apparatus for attaching light-shielding leader to photosensitive material roll
 A photosensitive material roll is mounted on a take-up shaft, and a light-shielding film having a width larger than the width of the photosensitive material roll is bonded to the leading end portion of the photosensitive material roll. A pair of slitters are positioned in respective slitting start positions on opposite sides of the leading end portion of the photosensitive material roll and spaced from each other by a distance substantially equal to the width of the photosensitive material roll. The light-shielding film is slit into a predetermined width larger than the width of the photosensitive material roll by moving the slitters away from each other in a direction parallel to the longitudinal axis of the take-up shaft while rotating the take-up shaft to take up the light-shielding film around the photosensitive material roll.
