A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced into opposite ends of alternating impingement slot nozzles, having delivery channels and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections. The slot nozzles and the pinch rollers work interactively to break down the chemical barrier layer.

Petit appareil de traitement d'impressions photographiques. L'appareil utilise un canal horizontal étroit de traitement et est formé d'une succession de rouleaux essoreurs et de buses d'imprégnation à fentes. La solution servant au développement photographique est introduite dans les extrémités opposées des buses d'imprégnation à fente alternées qui sont dotées de canaux d'alimentation. Les rouleaux essoreurs sont utilisés pour éliminer la solution de traitement du matériau photosensible et pour déplacer ce matériau. Le réglage du niveau de solution s'effectue au moyen de dispositifs d'écoulement situés sous la partie supérieure des sections tournées vers le haut. Les buses à fente et les rouleaux essoreurs agissent de concert pour dissocier la couche servant de barrière chimique.
