In a method of producing a substantially U-shaped guide rail in a groove formed in the respective window frame portion (23) of a slidably hinged window, a web- shaped elastic material which in the transverse direction is substantially flat, is formed into U-shape by bending the side sections (16, 18) relative to each other, said side sections being defined in the web-shaped material by longitudinal weakening grooves or weakening lines extending in parallel to one another and preferably formed in the side of the web material constituting the front face of the rail, and the material which is bent into U-shape is inserted in the groove of the associated window frame portion (23) in which it is secured by suitable means. To produce the guide rail, use is made of a blank of an elastic web material which is made by extrusion and stored in wound-up state. The lateral faces of the weakening grooves make an angle of slightly less than 90° with each other, such that the cross-section of the grooves is completely closed as the side sections (16, 18) are bent in order to form the guide rail.
Cette invention concerne une méthode de mise en place de glissières sensiblement en forme U dans la gorge des montants de cadre (23) d'une fenêtre basculante-coulissante, méthode selon laquelle une bande sensiblement plate de matériau souple est façonnée en forme de U en en repliant les marges latérales (16, 18) l'une vers l'autre, lesdites marges étant délimitées dans la bande de matériau par des rainures ou lignes d'affaiblissement parallèles ménagées de préférence du côté apparent de la glissière installée, et en poussant le profilé en U ainsi obtenu dans la gorge du montant de cadre (23) avant de le fixer en place par des moyens appropriés. La glissière est façonnée à partir d'un rouleau de bande de matériau souple obtenue par extrusion. Les faces latérales des gorges d'affaiblissement forment un angle légèrement inférieur à 90 degrés de sorte qu'après pliage des marges latérales (16, 18) lesdites gorges sont complètement fermées.
