Bobbin Rail & Building Motion

Assembly

The rail carrying all the bobbins and the building motion that raises and lowers it in shortening strokes while slowing it through the build, so the roving lays in tapered layers and the bobbin builds without ridges. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
