Abstract: A design of a two-for-one twisting spindle, particularly for continuous texturised yarns, incorporates a yarn storage plate (3) with drilling (2) of a narrower diameter (d) than the diameter (D) of the hollow spindle (1) through which the yarn (F) passes. When a yarn breaks, it is automatically drawn out of the hollow spindle in a sufficient length to allow it to be grasped for repair. In normal use, the yarn (F) is drawn from the bobbin (S) and passed through the hollow spindle (1) into the drilling (2) of the rotating reserve plate (3) to be drawn out through a yarn guide (5). The diameter (d) of the drilling (2) is narrower than the diameter (D) of the hollow spindle (1) so that the yarn (F) has free passage, but sticks in the drilling (2) when the yarn breaks. Pref. diameter (D) of the hollow spindle (1) is 4-5mm and that of the drilling (2) is 3mm. In the event of a yarn breakage the reserve plate (3) has a supply of yarn (F) in the drilling (2) which is readily available and accessible at the profiled rim (3a) of the reserve plate (3).
