Open ended spinning rotor has thin sidewall with center of gravity located behind fiber slip wall

摘要

A cross-wind textile assembly has an open-ended spinning rotor whose shaft has a magnetic bearing, a rotor cup, and a front-side rotor mouth to a fiber slip-wall, a rotor groove and a rotor base to a transitional zone. The rotor cup (29) is a thin-walled component whose center of gravity is at a notional point (50D) is located behind the fiber slip-wall as seen from the rotor mouth (30).
