摘要

Each of the two main parts (1, 2) is tracked by means of at least one central cut which does not go right through and extends along the body longitudinal axis. The main parts are then dried and a deepened formation is made at right-angles to the track cut and passing through the surface obtained by the first sawing process. A pair of main parts are then glued together with the surfaces obtained by the first sawing facing each other and the body is then given a predetermined shape.
