ABSTRACT:
An apparatus for automatically bonding or laminating a transparent protective cover sheet to the image-bearing surface of a photograph, preferably of the type prepared by a diffusion transfer process. The cover sheet includes a layer of fluid activatable bonding agent on one side thereof. The apparatus is configured to advance a photograph past a fluid treating station where its image-bearing surface is washed and wetted with activating fluid and simultaneously advance a cover sheet from one end of a stack to feed the photograph and cover sheet between a pair of pressure rollers which bring the photograph and cover sheet into superposition to effect the bond therebetween.
