Abstract
A method for starting a spindle of a cabling or two-for-one twisting machine, wherein a yarn reserve is formed on a take-up package, the machine has a workstation having a spindle pot for holding a first feed package and having a spindle rotor with a lateral outlet below the spindle pot, an outer yarn from one feed package is wound around an inner yarn from another feed package and the outer yarn is guided through the spindle shaft and its lateral outlet in a balloon orbiting the spindle pot to a yarn-guiding device above the spindle which merges the two yarn supplies, and a winding device in which the produced twist is wound onto the take-up package. A ratio of the take-up speed of the twist to the rotation speed of the spindle rotor is increased in comparison with the production data is used during creation of the yarn reserve.
