<p>Three hollow moulding beam (2) has the surface shell of its hollow profile (21) designed as a bonding surface over at least part of the total circumference of the moulding. In the longitudinal direction, it virtually covers the application width. The hollow profile is bonded to at least one other second profile (22-24,221,226), which has at least one surface complementary to the binding surface of the hollow profile. The planes are parallel and roughly equal in area, forming a one-piece construction of the beam.</p> |
