Abstract (en)
[origin: EP0414417A1] The specification discloses a method of assembling two different venetian blinds having two different slat widths, the flexible elements 14, 16 of a ladder means of which are each mounted on a tilt roll 10, the flexible element of each pair extending down the different opposite lateral outermost points 18, 20 of the tilt roll 10. Identical tilt rolls are utilized for the ladder means of the blinds of first and second widths. The flexible elements of each ladder means of the blind of slats of lesser width are attached to the respective tilt rolls 10 (Figure 1A), so that they extend directly from the securing means 12 of the tilt roll to the laterally outermost points 18, 20 of the roll 10. The flexible elements of each ladder means for the blind with the slats of greater width are attached to the respective tilt roll 10 , so that each of the flexible elements 14, 16 of each pair extends from the securing means 12 of the tilt roll 10 around at least half of the periphery of that tilt roll to reach the laterally outermost points 18, 20 of that roll when the blind is in its fully opened position. Thus the tilt roll must be rotated a greater distance for the blind of greater slat width than for that of the lesser slat width to give a given angle of tilt.
