The layers are welded to one another along their longitudinal edges so as to form a space between them in the shape of a channel (4). The inlet for the channel can be controlled by a non-return valve (6) whereas the exit can comprise a plug (7). The element is thermoformed by circulating a fluid heated to 130° to 140° C. through the channel until the foam becomes soft. | |
