Abstract: An apparatus for producing a photo-polymer plate having relief image areas thereon has a photo-polymerizable material feed device reciprocally movable along guide rails through a photo-polymerizable material layer forming station. The feed device has a frame supported on the rails by first and second pairs of wheels and carrying a bucket containing the photo-polymerizable material in liquid phase and tiltable to pour the material onto a protective sheet material placed on a photo-polymerizable material layer forming station when the feed device is moved over the protective sheet material. A doctor is mounted on the frame to level the layer as well as to preliminarily reduce the thickness thereof. A backing sheet material is placed over the layer to form an assembly of the two sheet material and the layer of the photo-polymerizable materials sandwiched therebetween.

Abstract: Process and apparatus for producing a photopolymer plate having relief images thereon. Successive portions of a continuous length of a protective film material are travelled in a horizontal elongated plane defined by a pair of parallel and spaced guide rollers. A layer of liquid photosensitive material is applied to a length of the horizontal web of the protective film material. A length of backing material is then laminated onto the upper surface of the layer to form an assembly. The assembly is moved by the protective film material into a relief exposure station for the exposure of the lower surface of the layer through an image-bearing transparency and the protective film material to an actinic radiation. The laminated portion of the backing material is separated from the remaining continuous web of the backing material. The image-bearing transparency is fed to the relief exposure station by a continuous length of another film material.
