Abstract
A method for coating a preformed core having two faces and an edge around the periphery of the core, which edge links the two faces, includes thermoforming of a polymer material. The coating is formed by the heating, gluing and vacuum application of the two sheets of polymer material which are applied successively to the two faces of the core in order to cover same completely. An automatic machine can be used to carry out the method. The method can be used to produce finished products, in particular surfboards, furniture or display objects.
