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. A laminating cylinder is mounted on the frame and disposed for rolling engagement with the backing sheet to reduce the layer to a predetermined thickness. A kind of jack is provided between the shaft of the second pair of wheels and the frame so that the operation of the jack is effective to pivotally rotate the frame about the axis of the shaft of the first pair of wheels whereby the distances of the doctor and the laminating cylinder to the surface of the protective sheet material are varied simultaneously for the adjustment of the thickness of layer. The first pair of wheels is disposed posterior to the second pair of wheels as viewed in the direction of movement of the feed device in which the photo-polymerizable material is poured to form the layer, whereby the amount of the adjustment of the spacing between the laminating cylinder and the protective sheet is smaller than that of the spacing between the doctor and the protective sheet at each time of adjustment.
