Abstract:
A prelaminate comprising a plurality of layers for collective insertion in a mutually fixed spatial relation into the pinch between co-acting pressure rollers,which prelaminate comprises:a carrier layer;a first glue layer arranged on the carrier layer and adhered thereto;a cover foil;a second glue layer arranged on the cover foil and adhered thereto,wherein the two glue layers are directed toward each other;wherein each of the above layers have substantially straight and mutually aligned leading edges and said layers being sequentially stacked in superimposed position over each other and are held in this registered position by registering means; andrejecting means for preventing mutual adhesion between the two glue layers and separates said glue layers,such that the carrier layer with the first glue layer and the cover foil with the second glue layer, with the exception of the leading edges with the registering means, are movable apart to receive therebetween a flat object for arranging fixedly and thus for encapsulating therebetween and carrying through the pressure rollers the layers with the flat object received therebetween for forming a laminate by means of glueing therewith, wherein the registering means includes a fourth glue layer mutually adhering each of the layers together, andwherein the leading edges of each of said layers are mutually connected together by said fourth glue layer forming the registering means and extending substantially transversely of and along the leading edges.
