PROBLEM TO BE SOLVED: To provide double spinning and twisting apparatus, and method in which tieing operation of yarn can simply and surely be performed. SOLUTION: This method for winding and spinning fibers onto the free ends of the two threads of a yarn that is produced by an integrated spinning and twisting process and two-for-one spinning and twisting apparatus for performing the method are provided. The method includes steps gripping a twisted yarn, separating two threads of the twisted yarn in a manner such that the twist which was originally present in each individual thread prior to the doubling of the thread with the other thread returns to the now separated thread portion and forming a thread loop of each separated thread portion in the area. Each thread loop is clamped by a spin joining apparatus 30 and respective portions of the two branches of the thread loop extend to a spinning rotor and the spindle hollow axle. Spinning is started in coordination with winding and the thread loop is dissolved as the now joined thread is drawn into the spindle hollow axle.
