Improvements in the construction of fixed blinds, obtained by cutting and embossing a metal sheet that can be a sheet or roll, characterized by the fact that the sheet is produced continuously, with unlimited longitudinal extensions and with any width, which depend only on the widths of the commercially produced sheets, all the slatted slats having the same longitudinal extension, obtained by successive short and embossed operations in the original metallic plate, occupying the entire width; each transverse series of slats joined to each other and to the other series of assembly, by flat elements of reduced width that are unrolled continuously throughout the longitudinal extension of the metal sheet; the angle of inclination of the slats being fixed to the plane of the metal sheet, but blinds can be manufactured at any predetermined angle; the planar elements being developed longitudinally in all the longitudinal extension of the original metal sheet and serving to fix the slats, all having the same width, even those of the lateral ends, making possible the juxtaposition of two segments of the shutter overlapping the extreme longitudinal elements, allowing surfaces with wider widths to be covered with the blind, without interruption.
