Abstract
A pot spinning method and apparatus wherein a spinning pot rotates during spinning about a vertical axis while an associated yarn guide tube delivers fiber material through an exit mouth of the yarn guide tube onto the rotating inside surface of the spinning pot in the form of a revolving extent of the yarn which also rotates about the axis of the spinning pot. A yarn break or unacceptable changes in quality of the spun yarn can be ascertained extraordinarily quickly if deviations in the duration of the revolution of the yarn extent at the mouth of the yarn guide tube are monitored.
