A machine for production of finished lath packs for Venetian blinds, which have holes at the ends for draw cords and ladders consisting of bands or strings, every cross band of which carries a lath, and where two neighboring cross bands of a ladder are placed on each side of the draw cord passed through the holes. The machine has a mechanism which inserts laths at each ladder, a mechanism which lifts the inserted lath and the ladders as well as devices to retain the raised lath. Each lifting mechanism has a carrier with a slit through which the ladder stretches and, on both side of the slit, carrier faces sloping away from each other for an inserted lath. The carrier can tilt in such a way that the carrier faces support the laths alternately. The carriers are tilted synchronously with the movement of the feed mechanism. The carrier is thus used also for positioning the ladder with the consecutive cross bands placed on one and the other side alternately of the draw cord. |
