  • Patent number: 6470631
    Abstract: The invention includes methods and apparatus for fabricating a skating ring. One such apparatus is a curved element for skating rings which includes a plurality of vertical sup5 ports which are adapted to any curve shape. The apparatus further includes a plurality of horizontally arranged ribs and abutting double-curved shell segments made of several plane-like wood layers which are glued to each other. By being fixed to the support elements and ribs, the shell segments form a skating surface to be ridden on by skaters or the like. The shell segments are pre-shaped as at least one of single- or double-curves such that they can be fixed essentially stress-free onto the support elements and ribs. One method of the present invention includes a method for manufacturing shell segments for curve elements for skating rings. The shell segments include a plurality of plane-like layers of wood.
