The method is characterised in that it consists in unrolling at least two strips intended to form the component parts (2, 3) of the first layer of the body (1), in shaping them and placing them in such a way that they are joining without overlapping, then in unrolling at least two strips intended to form the component parts (4, 5) of the second layer of the body (1), in shaping them and in positioning them in such way that they are also joining without overlapping, these operations to be continued, if necessary, depending on the number of layers provided, the joints, (6, 7) of the strips of each possible additional layer being substantially offset with respect to those of the strips of the preceding layer, and finally in cutting off and removing the packing body (1). <IMAGE> |
