<p>The screen is formed by a rigid frame covered with a layer of tensioned fabric (3). The frame is made from rigid extrusions (5), fixed together by corner joints (6), and equipped with a fixing system for the fabric panel. This can be in the form of self-adhesive strips on the panel edge and frame, or in the form of extruded strips (9) with projecting tongues (24), fixed along the edges of the fabric panel and engaging with matching grooves (8) in the edges of the frame. The rigid extrusions which make up the frame are trapezoid in section, with their larger bases (21) facing outwards and equipped with the grooves for the tongues fabric strips.</p> |
