Since the spindle pulls the traveller around after it, the yarnis twisted or spun as it is wound on the bobbin. Sometimes two spoolsof roving are spun into a single thread, but more frequently there is nocombination. All the rings on one frame, usually about 256, aremoved up and down together on their spindles, so that yarn will bewound evenly on the bobbin. *Mule Spinning is briefly described in Wool and Wool Manufacture. 1261.
