Abstract

Improvements made in the manufacture of venetian blinds with reel for the lifting cords, whose blinds comprise a set of ladders and slats that includes a lower bar that extends along the lower edge of the set, and a plurality of lifting cords, which they extend upwards from the lower bar in separate positions along their length, characterized in that the lower bar carries elastic means, the lifting cords being connected to the elastic means, which are normally under tension by the weight of the lower bar , and that elastically absorb looseness when one or more lifting cords are relieved of tension.
