ABSTRACT:
An arrangement for conveying superimposed photographic sheets into a processing bath includes a pair of cooperating rollers each of which has a central section of reduced diameter. A guide sheet having the shape of an isosceles triangle is arranged downstream of the rollers. The apex of the guide sheet confronts the rollers while the base is remote from and extends parallel to the rollers. A wedge-shaped ledge spans the guide sheet adjacent to the base on either side of the guide sheet. The ledges function to space the superimposed photographic sheets being conveyed. A tongue which initially separates the photographic sheets projects upstream from the apex of the guide sheet and extends between the central sections of the rollers. A part-spherical protuberance is formed on either side of the junction between the tongue and the guide sheet. The protuberances displace the photographic sheets so that the leading edges of the latter do not catch at the corners between the tongue and the guide sheet.
