Method of making a flanged fluted self-coiling sheet

A compact, self-retracting imbibition chamber for cameras in which the film is ejected just after exposure and passed through processing units which distribute processing fluid throughout the film unit. The apparatus includes a normally tightly coiled imbibition chamber which receives the sheet ejected from the processing rolls and retains it in a light-protected condition until it is sufficiently processed to allow it to be exposed to the light.
