Abstract
The method produces a slatted external air grille for the end of a ventilation conduit etc. A section of sheet steel is cut out, having the dimensions of the finished article, and fold lines (4) forming one side of each slat (3) are stamped in it. Slots extending round the other sides of the slats are then cut or stamped out, and the slats are bent out along the fold lines. Fold lines for a peripheral strip can be stamped at the same time as those for the slats.
