ABSTRACT In a machine for producing venetian blinds, a strip of slat material is intermittently fed by a feeding device to a mounting station where slats (20, 20') are mounted in a number of ladder tapes (17) at threading stations (12). Punching devices (30) for punching the strip of slat mate- rial comprise according to the invention a punching tool (30) which is movable laterally relative to longitudinal direction of the strip of slat material between an opera- tive position in which the die (32) and punch (33) of the punching tool are in the correct position for punching the strip of slat material, and an inoperative position in which the die and punch of the punching tool are position- ed laterally outside the strip of slat material. The punching devices can have at least one cutoff or separat- ing punching tool for cutting or separating individual slats (20) from the strip of slat material. The punching device of the venetian blind production machine comprises a punching tool (30) with a die (32) and a punch (33) for punching or cutting a strip of slat mate- rial for the forming of slats (20). According to the invention, the punching device comprises a moving or driv- ing mechanism (40-42) which moves the punching tool between an operative position in which the die and punch of the punching tool are in the correct position for punching the strip of slat material, and an inoperative position in which the die and punch of the punching tool are positioned laterally outside the strip of slat mate- rial.
