Abstract

The verticals (2,3) of a venetian blind ladder cord (1) are connected by rungs formed with two crossed cords (4) to give a stable slat seating. During the crocheting of the ladder, openings (6) are formed at regular intervals in the ladder legs, by one thread being pulled to one side from the cord to form a loop. A ladder cord produced thus, in lengths, by a continuous process, can therefore be cut to suit any size of blind, and fixed by locking pins to the tilt drive rod and the bottom rial.
