1. A method of producing a laminated panel having a backside formed of a normally rigid substrate in an essentially self-supporting thickness and a frontside formed of a differentially segmented cover layer bonded to said substrate by moldingly interconnecting a layer of said substrate in a moldable state and a differentially segmented sheet for providing said cover layer;

  • said segmented sheet having at least two differing segments and at least one seam line between adjacent segments;

    the improvement comprising the step of forming, in a portion of said panel corresponding essentially to a predetermined position of the visible junction line between said differing segments in said frontside of said laminated panel, a fold to protrude from said backside and comprising a folded double layer of said segmented sheet as an inner fold portion and an outer fold portion formed of said substrate;

    said folded double layer having a length corresponding to at least about 100% of said self-supporting thickness of said substrate and including said seam line of said segmented sheet within said fold so as to compensate an off-set between said seam line of said segmented sheet and said predetermined position of said visible junction line on said laminated panel.
