PURPOSE:To carry out roving ending during operation of a spinning machine, by providing a roving ending machine body running along the machine frame with a full bobbin supporting head, roving end taking out device, roving ending head and roving threading device. CONSTITUTION:When roving bobbins (2B) and (2F), hung from bobbin hangers of a creel and subjected to spinning are converted into small packages, at least two hull bobbins 1 are rotated in the unwinding direction by a roving end taking out device to carry out picking of the roving ends, which are then plied on rovings taken out of a pair of the front and back small bobbins during spinning by a roving ending head to carry out roving ending. The rovings of the small bobbins on the upstream side of the roving ending part are divided into parts by a roving device and the rovings after roving ending are hooked on a roving threading guide 10. Roving ending is successively carried out from one end to the other of a machine frame 3 by this roving ending machine 30 to hook the rovings of the full bobbins hung from a spare rail 13 on the roving guide or spinning.
