A method is provided to easily fit a door on its surrounding frame by means of an elongated T-molding. Such a T-molding comprises a channel strip having an outer surface defining a portion of the peripheral edge of the door, and an inner surface on which is fixed a longitudinal leg or a plurality of pins. A first alternative is to cut a longitudinal external groove into a vertical, peripheral stile of the door, and to insert the longitudinal leg more or less deeply into the groove so as to adjust the dimensions of the door. Another alternative is to bore holes into the stile and to insert the pins of the T-molding more or less deeply into these holes. The leg and the pins are provided with outer ridges to fixedly attach the T-molding. The pins and holes are particularly suitable for an improved door having an inner frame (2) made of tubular members (8-13) each defining a cavity which communicates with empty spaces defined within the door through a longitudinal opening of the member (8-13). By filling with polyurethane foam these spaces, openings and cavities, the tubular members (8-13) are fixedly attached to the door and the rigidity of the latter is increased.
摘要:
Vor dem Verschweißen werden die Enden der beiden Kunststoffprofile derart profiliert, daß jeweils zwei Be reiche entstehen. Der Bereich (1) besitzt eine vordere Endfläche (10), die vom Schweißspiegel erwärmt wird, während der sich daran anschließende seitliche Be reich (2) eine abgeschrägte Endfläche (23) aufweist. Beim Verschweißen entsteht auf diese Weise nur an der Seite des Bereiches (1) eine Schweißraupe, während an der Seite des Bereiches (2) eine Schweißraupenbildung unter bleibt.
