PHOTOSENSITIVE MATERIAL The invention relates to the conditioning of photographic web materials and more particularly, to a magazine allowing to transport and use very long webs wound around cores.

The applicant already developed such magazines and reference will be made to O-A-91/12561 and O-A-91/19222 for a better understanding of such magazines. The magazine disclosed in these applications allows to wrap photographic paper webs, the length of which is close to 2000 m. According to the application filed on June 8, 1990, the magazine includes lighttight output slots allowing to extract the photographic paper for subsequent use.

The invention is directed to provide another embodiment for such a magazine. Indeed, different types of cutting devices exist, the magazine type which will be disclosed subsequently is more appropriate to some types of cutting devices.

The object of the invention is achieved by means of a collective, reusable magazine for several rolls of photosensitive web material, the axis of which is substantially horizontal. This magazine includes a base appropriate to the handling by means of a lift truck and a rigid, lighttight case enclosing the photosensitive material rolls. It is characterized in that each roll is maintained in its position where its axis is horizontal, by two support-rollers. The sole figure schematically illustrates a magazine according to the invention.

The magazine according to the invention resumes the functionalities exposed in French patent application 90 01858 filed on February 12, 1990 and in French patent application 90 07375 filed on June 8, 1990. It can be referred to these two not yet laid open applications for a

better understanding of the purposes and advantages of the invention.

The magazine in its simplest version includes a base 10 designed for the handling by means of a lift truck, a rigid, lighttight case 20, designed to protect the photosensitive material and series of support-rollers 30 arranged under each roll.

Advantageously, container 210 and cover 211 define on the front face, parallel to the roll axis, a lip system 220, 221 allowing to extract the photosensitive material. The shape and the materials used for manufacturing these lips are well known in the photographic art. For example, the lips can be coated with velvet preventing the light from entering the magazine while allowing the extraction of the photosensitive material without deterioriating the photosensitive material. in a preferred embodiment, the outer shape of the lip system can be similar to the one disclosed in O-A-91/19222 by refering to Figure 2 , thus allowing an easy cooperation of the magazine with a cooperating device.

It is obvious, in an improved embodiment, that the magazine is provided with means (40, 50) allowing that the rolls do not come out of the support-rollers associated therewith. Advantageously, these means will be arranged inside the cover and can take the form of a resilient device (40, 50) capable to move between two positions. In the first position or working position, the device is far from the web rolls and releases these ones so that to allow their rotation by means of the traction exerted on the free end coming out of the charger. In the second position or locking position, the device bears on the outer convolution of the rolls not yet used, in order to lock them during the movements of the magazine.

As schematically shown on the figure, the resilient device can be formed of a pad 50 coated with a thick resilient material such as, for example, polyurethane foam.

This pad is connected by an arm 60 to a crank 40, at the outside of the charger, thus allowing to place it in either previously described positions.
