Abstract: A loading apparatus for transferring a first roll from a preparation apparatus to an unwinding apparatus. The preparation apparatus includes a shaft onto which a first roll is loaded, and supports connected to a vacuum source to maintain the web wound about a circulation loop. When a second roll loaded on the unwinding apparatus is expired, the preparation apparatus is rotated about an axis to register the preparation apparatus' shaft with the unwinding apparatus' shaft, and the first roll is then transferred from the preparation apparatus' shaft to the unwinding apparatus' shaft. The ends of the first and second rolls are attached.

Abstract: A cutting module comprises a circular knife and a circular bedknife rotatively mounted on a frame in such a way that their respective axes are substantially parallel to each other. The distance between the axis of the knife and the bedknife is such that their respective periphery is brought close together or brought to bear on each other over a part of their periphery in order to cut a web passing between the knife and bedknife. The knife or the bedknife are mounted on a mechanism provided with an adjustable eccentric so as to adjust the penetration by modifying the height of engagement of the knife with respect to the bedknife.

Abstract: A container for a photosensitive product in strip form wound on a spool including a) a lightproof enclosure having two end walls, at least one of the end walls being able to be opened so as to define an end opening allowing the insertion/withdrawal of a roll of the photosensitive product in strip form; b) a cantilevered spindle mounted inside the enclosure in order to receive the spool, the spindle being mounted perpendicular to the end walls; and c) a ring for driving the roll out of the enclosure, through the opening.
