<p>The cartridge has an external cylindrical partition (1) and an internal cylindrical partition (2). The internal partition (2) is maintained inside the partition (1) so as to form an annular closed space (3). This space is sealed at each of its ends by annular joints. The external partition (1) has two slots (5a, 5b) on its periphery. The length of the slots is at least equal to the width of the film (7). The two annular joints each have slot (6b) in them. These slots are arranged facing each other and form an open loop guidance path for the film (7). The film (7) is introduced into the gap (3) through the slot (5a) and leaving by the slot (5b). The internal cylindrical partition (2) has at least a slot (8a, 8b) formed in a mid zone of the open loop guidance path. This slot (8a, 8b) connects the annular space (3) to a reservoir (10).</p> |
