摘要

Improvements in the manufacture of slat curtains, of the type comprising slats supported in parallel by ladders suspended from a tilting mechanism that allows to modify the inclination of such slats, as well as traction belts that make it possible to raise the curtain and that pass through the slats by openings cut in them, which is characterized by the fact that the opening of the slats that gives way to a pull tape is given the form of a slit perpendicular to the longitudinal axis of the blade itself, provided in this slit a width, according to the longitudinal direction of the blade, slightly greater than the thickness of the belt, to form a narrow guide that opposes any twisting of the belt.
