Mechanical dobby for Magic Dobby

With the mechanical dobby, you program the pattern, just as you would when tying the treadles. The so-called selection bars are equipped with numbered holes that correspond to the shafts. By inserting pins into these holes, you determine which shafts are pulled up. A pedal is used to move the interconnected selection bars forward or backward. The mechanical dobby comes with 30 selection bars and 600 black pins.
