Abstract
An open-end spinning machine incorporating a doffer robot also includes separate tracks for the doffer robot and a piecer-cleaner robot. The robots are able to patrol continuously along one side of the machine and back along the other side of the machine, with sufficient separation for the doffer robot to pass the piecer-cleaner robot, and vice versa and for the two robots to pass end casings of the machine.
