    Summary

    [edit]
    Description
    English: Base of a braiding machine, with two tracks, one shaded in green and one shaded in red. Four bobbin carriers slide along each of the two tracks. The four bobbin carriers shaded in green travel around the green loop in the clockwise direction, and the four bobbin carriers shaded in red travel around the red loop in the counter-clockwise direction. As the two tracks cross over, the strands twist around each other, making a braid. In the case of this particular machine, eight strands are braided into a square braid.
    The carriers are pushed by four horn-gears in the base plate. Each of the horn-gears has a gear and a horn on a common shaft. The gears intermesh with each other, with alternate gears traveling in opposite directions. Each horn has four slots for pushing a bobbin carrier. The bobbin carriers get passed along from one horn th the next as they make their way along the track.
