The present invention relates to a method for automatic bow adjustment for a venetian blind assembly machine; said bow adjustment station comprising rollers (48; 104, 106) for guiding, bending and levelling a strip material (43; 112), and further comprising a forming section (36; 102) where mating concave and convex upper and lower form rollers (50; 108, 110) are arranged for creating a transverse curvature in the strip material, further comprises the steps of: providing levelling through means for offsetting (34; 100, 102) in order to straighten the bow of the strip material (43; 112) within a predetermined deviation on a predetermined length of strip material; measuring the deviation through optical means (146) providing a deviation signal; and adjusting the levelling by said means for offsetting (34; 100) through the deviation signal, if said measured deviation exceeds a predetermined deviation, in order to keep the deviation within said predetermined deviation. In addition, the present invention also relates to an arrangement for automatic bow adjustment for a venetian blind assembly machine. An advantage over prior art is that the bow adjustment is better controlled, the adjustments can be done with an increasing rapidity and a decreased wastage of strip material is obtained.
