Apparatus for assembling slats of venetian blinds

A machine for production of finished lath packs for Venetian lath blinds, the superjacent laths (2, 2') of which have punched holes (8) at least at the ends for draw cords and ladders (3) consisting of bands or strings, every cross band of which carries a lath, and where one of two neighboring cross bands of a ladder is placed on one side while the other is placed on the other side of a draw cord passed through the punched holes (8), which machine has a feed mechanism which inserts laths (2) one by one over a cross band in a suspended ladder (3) and at each of the suspended ladders a lifting mechanism (1) which lifts the inserted lath and the ladder (3) so that a following lath is inserted over a following cross band of the ladder, the machine also having devices to retain the raised lath, characterized in that each lifting mechanism has a carrier (1) with a slit through which the suspended ladder (3) stretches and, on opposite sides of the slit, oppositely inclined carrier faces (5) for engaging an inserted lath (2), which carrier can turn on an axis (6) stretching across the lower side of the inserted lath between one end position where one carrier face supports the lath and another end position where the other carrier face supports the lath, the machine also having a mechanism (9-12) to swing the carrier (1) from the one end position to the other end position synchronously with movement of the feed mechanism.
