ABSTRACT:
A section constituting an outer longitudinal element or moulding of a false ceiling or false wall, is constituted substantially by an angle of which the vertical flange is applied against a wall and the horizontal flange presents a shoulder extending towards the vertical flange to ensure fastening of a hook-shaped edging fast with a sheet of plastics material or cloth maintained stretched by the section.
The horizontal shoulder defines, with the horizontal flange, a groove whose cross section is in the form of a U open towards the vertical flange. A cant provided in the angle constituting the section joins the horizontal flange inside the U-groove so as to define, between this cant and the shoulder, a narrow passage of width slightly larger than the thickness of the part of the edging which is engaged in the U-groove.
