Abstract
For sealingly joining an underroof to a skylight or another roof installation a fitting collar is provided comprising a film element (7, 8) with a substantially U-shaped plane configuration with a cutout, at the sides of which there are flange parts (9, 10) for attachment of the fitting collar to mutually adjoined exterior sides (1-4) of the main frame structure of the window or the roof installation, in such manner that the film element is brought to extend substantially in parallel with the roof surface, in order to connect with adjacent parts (5, 6) of the underroof. The fitting collar can be manufactured in a simple manner, in that there in two overlapping lengths of film is produced transversal welds, at distances corresponding to a prescribed main frame width, whereby an obliquely extending part of each weld is formed with two parallel welded seams, while there in the edge zones at the opposite side edges of the lengths of film in extension of one and the other, respectively, of the two parallel welded seams are produced welded seams, which are perpendicular to the side edges. The collar elements are then separated by cutting along the cutting lines (22) between the parallel …
