Title
(EN) STRETCHER FOR PAINTING CANVAS
(FR) CHÂSSIS, EN PARTICULIER POUR DES TOILES
Abstract
(EN)
A stretcher comprises frame sections. The frame sections comprise two extruded profiles (B, D) whereby the outer profile is made of a softer material than the inner profile. The inner, hard profile (D) gives firmness to the stretcher, while the softer profile (B) provides flexibility. The softer profile is fitted with a flexible wall that can hinge around a hinge line. This makes it possible to accommodate variations in canvas tension, while at the same time ensuring a strong stretcher. The frame sections are fitted with adjustment mechanisms-(F, L).
(FR)
Le châssis selon l'invention comprend des sections cadre. Les sections cadre comprennent deux profilés extrudés (B, D). Le profilé externe est composé d'un matériau moins dur que le profilé interne. Le profilé interne, plus dur, (D) apporte de la fermeté au châssis, alors que le profilé externe, moins dur, (B) apporte de la flexibilité. Le profilé le moins dur est de préférence doté d'une paroi flexible pouvant être articulée autour d'un axe d'articulation. Cela permet d'adapter la tension de la toile tout en garantissant en même temps la solidité du châssis. Les sections cadre sont de préférence dotées de mécanismes de réglage (F, L).
