Abstract:
A method of the invention consists in that at least one continuous spiral or serpentine cut is made through a flat workpiece, preferably a wooden plate, with subsequent deformation of the cutout portion in the direction perpendicular to the plane of the flat on workpiece, so that an elevated element or elements are formed on the workpiece turning it into a three-dimensional item. The cutout is made at an angle different from 90 so that the spiral or serpentine cut has a tapered shape in the thickness direction of the flat workpiece. The tapered shape of the cut facilitates fixation of the elastically deformed protruding element due friction between the engaged tapered side surfaces of the cut. The above deformation and protrusion become possible due to a certain width of the cut equal to the thickness of the cutting tool. The decorative effect can be emphasized if the workpiece is painted so that after the formation of the three-dimensional body the non-painted surfaces on the sides of the protruding elements, which are of a color different from the painted surface, form a pattern of different color on the painted background. If necessary, these side surfaces can be colored with the same or different paint. The products can be formed as decorative articles or as various functional items such as fruit or bread holders, or the like. The invention also relates to articles produced by the aforementioned method.
