The invention discloses a method for end re-splitting spinning of a bobbiner. The method comprises the following steps: 1, when a lower keel moves to an end splitting position, controlling a drafter motor and a lower keel motor to stop and controlling a flier motor and a bobbin rotating body motor to rotate and to stop after rotating in an opposite direction of a normal spinning direction; 2, controlling the flier motor and the bobbin rotating body motor to rotate and to stop after rotating in the same direction as normal spinning; and 3, entering a normal spinning state and controlling a lower keel to rotate, wherein the lower keel moves first in a direction away from an upper keel and in a direction close to the upper keel when rough yarns cover a flocking part of the bobbin, and the drafter motor, the bobbin rotating body motor and the flier motor operate according to the direction and speed for normal spinning to complete re-splitting operation. The successful re-splitting rate of the invention is high.
