发明名称 METHOD FOR MOUNTING THE SLATS OF A VENETIAN BLIND IN THE SLAT SUPPORT CORDS AND MEANS FOR CARRYING OUT THE METHOD
摘要 A method of mounting the slats of a venetian blind in the slat support cords of the blind, the slats being provided with holes through which the hoist lines of the blind are passed in a manner such that the lines are located on alternate sides of consecutive cross members of the slat support cords. The ladder cords are given a permanent tendency to fall into a concertina like configuration when no tension load is applied thereto so that subsequent to placing the slats in position and bringing the slats together to form a pack the cross members fall on alternate sides of the hoist line holes. Thus, when threading the hoist lines through their respective holes, the lines automatically pass on alternate sides of successive cross members.
