The invention concerns a method for fixing a first construction (31) made of a plastic material to a second construction (32a, 32b) made of a plastic material. In the method, the first construction and the second construction are fixed to one another by means of seaming devices (34), which form seams (33) at the desired locations. The first construction (31) is placed, in its ring-shaped, between the film faces (32a, 32b) that form the second construction, in which case, during seaming, there are at least four material layers placed one above the other. The first construction (31) is fixed by seaming from the desired locations by means of seams (33) to the second construction (32a, 32b) so that the outer face of the first construction (31) is fixed by seaming to the inner face of the second construction (32a, 32b), but the inner faces of the first construction (31) are not fixed to one another by seaming. |
