Abstract

"IMPROVEMENTS IN THE MANUFACTURE OF BLINDS", characterized by obtaining, by means of an extrusion phase of synthetic material, longitudinal slats of thin walls and hollow profile equipped, on their two front and rear sides of the body of the slat, of some walls convexes joined together and internally by means of two separate transverse partitions extended along each slat, with the particularity that, on the one hand, said transverse profile is molded leaving its lower edge, entering inwardly and opened by a longitudinal slot of scarce width defined by two inclined and lateral partitions with respect to said slot, while the upper edge of each slat is molded so as to be complementary and fit into the corresponding lower recess of the upper slat, endowing said upper edge, in its upper edge, of a vertical and longitudinal straight partition provided with holes and topped by appendices Like a T consisting of two substantially horizontal arms, in which case the successive slats thus produced are concatenated by longitudinal sliding of said upper vertical partition in the lower slot of the slat that is to be located above it and so on. with the sole exception of the lower blade that acts as a lower counterweight, which is linked in the same way with the penultimate one, having molded the same with flat walls in whose hollow interior devoid of transverse partitions has previously been housed a metal strip arranged in U that it is retained in said interior by the elasticity of the branches of the metallic U that are applied under pressure inside its housing.
