CA 2091314

It is well-known to use grooves to guide photographic material through processing apparatus. However, there is a tendency for debris to accumulate in the bottom of the grooves. Furthermore, the machining operation needed to form such grooves is complicated in particular where bends and changes in direction are required. Described herein is a guiding arrangement in which pairs of parallel plates (20, 22, 24, 26) are used to define a gap (30) through which material (40) is transported. The arrangement comprises an upper plate pair (20, 22) which is arranged to be offset with respect to a lower plate pair (24, 26), the plates in each pair being parallel to one another.

On utilise couramment des rainures pour guider le support photographique dans l'appareil de traitement. Cependant, des débris ont tendance à s'accumuler au fond des rainures. En outre, l'usinage nécessaire pour former ces rainures est compliqué, en particulier aux endroits où il faut faire des courbures. La présente invention décrit un dispositif de guidage dans lequel on utilise des paires de plaques parallèles (20, 22, 24, 26) pour définir un passage (30) dans lequel est transporté le support photographique (40). Le dispositif comprend une paire de plaques supérieures (20, 22) décalées par rapport à une paire de plaques inférieures (24, 26), les plaques de chaque paire étant parallèles l'une à l'autre.
