<p>1. Process for producing heat-insulating composite profiles which are formed from at least two metal profiles (4, 5) and from an insulating material (10) introduced in liquid form into a free space (6) provided between these metal profiles (4, 5), the insulating material (10), in the hardened state, filling the free space (6) only partially, in the manner of bridges connecting the metal profiles (4, 5) to one another and, after the insulating material (10) has hardened, the metallic connection being broken on opposite longitudinal sides of the free space (6), characterised in that the metal profiles (4, 5), which are held together to form the free space (6) intended for receiving the insulating material (10) and sealed off on the longitudinal sides of the composite profile not connected to one another metallically, are rotated about at least one filling tube (8), effecting the introduction of the liquid insulating material (10), and inserted into the free space (6), and in that all the walls of the free space (6) closed on all sides are coated with insulating material (10) in this way.</p> |
