Abstract
Blind slat, characterized by being essentially constituted by a hollow profile formed by external and internal walls respectively, joined by transverse partitions, one of said partitions being arranged on an edge of the profile and on an inclined plane, from whose upper end a flange bent in acute dihedral angle whose free edge is slightly separated from the inclined plane, while another partition constitutes the opposite longitudinal edge of the profile in question, and forms an obtuse dihedral angle, from one end of which extends a longitudinal flange provided with two Bends that give rise to the division of said flange into three sections, the two ends parallel to said walls and the central one in an inclined plane, the assembly adopting an irregular polygonal section, open to allow the crimping of a twin profile, by means of the flange of the opposite edge.
