Abstract
A doffing apparatus for removing a row of yarn tubes from a row of upright spindles has a support and a row of grabs mounted on the support, each engageable with a respective tube of a respective spindle, and movable for lifting the tubes off the spindles. Respective sensors at the grabs detect the presence of tubes in the respective stations and generate individual outputs respectively corresponding to the absence of tubes in the respective stations. A controller connected to all the sensors receives the outputs therefrom and stops the apparatus on detection of no tube in any of the stations.
