• This band ensures, once the section closed on the panel, both the adhesion of the frame on the panel and the seal between the frame and the panel, necessary during the exposure of the assembly outdoors, especially on building structures. It is understood that the aforementioned problems related to the difficulty of introducing the panel in the U-section of the profile, because of the presence of the adhesive tape, are here solved because the panel can be applied against one of the surfaces , most commonly, but not exclusively, the surface (5), without touching, during this implementation, the other surfaces.
• the invention is even more interesting if, as indicated in FIG. 1, the angles between the surfaces (1) and (3) as well as (3) and (5), typically 125 ° in the case of the 1, are sufficiently important to allow the establishment of the panel, in a translational movement along an axis substantially perpendicular to the surface (5), to position and fix, typically by gluing, the panel, without touching the other surfaces of the profile section concerned.
