It is suggested in connection with the production of slat packages for Venetian blinds whose slats (3), placed over each other, are introduced between a first and a second transverse band (2, 2') in double rungs in carrying bands or ladders (1) consisting of bands or cords, and where the slats (3) are conveyed one by one tothe carrying band (1) and lifted after being introduced into a double rung (2, 2') - in order to enable mechanical introduction of the slats - that a double rung (2, 2') should be stretched between two teeth (4) projecting over the plane in which the slats are conveyed, that a slat (3) is conveyed forward until it has passed under the first of the two transverse bands (2, 2'), and that the slat (3) is then lifted so that when further conveyed it passes over the second of the two transverse bands (2, 2'). The slat (3) can be lifted by means of an inclined plane (5) placed between the teeth (4).
