 Procédé de fixation sur un support de papiers ou films photographiques à développer et dispositif pour la mise en    aeuvre   du procédé La présente invention a pour objet un procédé de fixation sur un support de papiers ou films photographiques à développer. 



  Il est connu de maintenir les papiers ou films photographiques sur un    tambour   faisant partie d'un appareil à développer, au moyen de tiges ou barres fixées, par exemple, aux extrémités du tambour par des vis ou par tout autre moyen. Ce mode de fixation est non seulement compliqué et 'fait perdre du temps, mais encore risque    d'abimer   les papiers ou films retenus de cette façon. 



  La présente invention vise à remédier à    ces,   inconvénients et le procédé qui en fait l'objet se distingue par 1e fait qu'on place les papiers ou films sur un support    formé   au moins en partie d'un métal ferromagnétique et on maintient ces papiers ou films appliqués contre le support à l'aide d'éléments magnétiques. 



  L'invention comprend également un dispositif pour la mise en    oeuvre   du procédé ci-dessus, ce dispositif étant caractérisé par un support formé au moins en partie d'un métal ferromagnétique et par des éléments magnétiques destinés à être fixés    magnétiquement   sur ledit support en appliquant les papiers ou films contre celui-ci. 



  Dans une forme d'exécution particulière du dispositif que comprend l'invention, le support destiné à recevoir les papiers ou    films   photographiques est constitué par un tambour en acier inoxydable, les éléments magnétiques étant des barres    aimantées   de longueur quelconque venant se plaquer sur le tambour par-dessus les papiers ou    films.   Ces barres, qui peuvent être en un métal magnétique ou en une matière plastique contenant une matière magnétique, sont de longueur variable et    présentent   une certaine souplesse leur permettant d'épouser la forme du tambour. On placera autant de barres aimantées qu'il en faut pour maintenir les papiers ou    films   bien appliqués contre le tambour.

   Le développement des papiers ou    films   se fait par la rotation du tambour dans les différents bains dans lesquels il est plongé. 



  Dans une variante, ce tambour, au lieu d'être entièrement en un métal ferromagnétique, pourrait être formé par des éléments en matière non magnétique et des éléments en matière magnétique, ces divers éléments étant. par exemple, empilés de manière à constituer un cylindre dont la surface est ensuite soigneusement usinée et polie. Cette dernière solution est moins coûteuse que celle utilisant un tambour entièrement    cri   acier    inoxydable.   



  On pourrait également prévoir le tambour ainsi que les barres de fixation en une matière plastique telle que du chlorure de polyvinyle contenant des particules aimantées ou toute autre matière ayant des propriétés magnétiques. 



  Au lieu d'un tambour, on pourrait    utiliser   tout autre support. notamment un support plat. 



  L'avantage du dispositif décrit réside dans le fait que la fixation des papiers ou films à développer sur le tambour est considérablement simplifiée.

 Method for fixing onto a support of photographic papers or films to be developed and device for implementing the method The present invention relates to a method of fixing onto a support of papers or photographic films to be developed.



  It is known to hold photographic papers or films on a drum forming part of an apparatus to be developed, by means of rods or bars fixed, for example, to the ends of the drum by screws or by any other means. This method of fixing is not only complicated and wastes time, but also risks damaging the papers or films retained in this way.



  The present invention aims to remedy these drawbacks and the method which is the subject thereof is distinguished by the fact that the papers or films are placed on a support formed at least in part from a ferromagnetic metal and these papers are maintained. or films applied against the support using magnetic elements.



  The invention also comprises a device for implementing the above method, this device being characterized by a support formed at least in part from a ferromagnetic metal and by magnetic elements intended to be fixed magnetically on said support by applying papers or films against it.



  In a particular embodiment of the device included in the invention, the support intended to receive the photographic papers or films is constituted by a stainless steel drum, the magnetic elements being magnetic bars of any length coming to rest on the drum. over papers or films. These bars, which may be of a magnetic metal or of a plastic material containing a magnetic material, are of variable length and have a certain flexibility allowing them to conform to the shape of the drum. As many magnetic bars will be placed as necessary to keep the papers or films well applied against the drum.

   The development of the papers or films is done by the rotation of the drum in the different baths in which it is immersed.



  In a variant, this drum, instead of being entirely made of a ferromagnetic metal, could be formed by elements made of non-magnetic material and elements of magnetic material, these various elements being. for example, stacked to form a cylinder, the surface of which is then carefully machined and polished. The latter solution is less expensive than that using an entirely stainless steel drum.



  The drum and the fixing bars could also be provided in a plastic material such as polyvinyl chloride containing magnetic particles or any other material having magnetic properties.



  Instead of a drum, we could use any other support. in particular a flat support.



  The advantage of the device described lies in the fact that the fixing of the papers or films to be developed on the drum is considerably simplified.
