ABSTRACT:
Apparatus for peeling positive print sheets from disposable components of peel-apart diffusion transfer film unit assemblies which comprises an open bottom chassis capable of being positioned over a receptacle and supporting a rotatable drum for carrying a processed film unit assembly into operative relationship with peeling blade assemblies to remove the print and release the remaining components of the film assembly for disposal through the open bottom of the chassis. The peeling components engage only marginal portions of the print and involve a combination of a movable peeling blade to engage the leading marginal edge of the print and a pair of fixed peeling blades which engage the side margins of the print and retain the print for manual removal from the apparatus.
