Abstract
A method of cleaning a yarn supply package protective pot and, preferably, a balloon limiter device of a spindle assembly of a two-for-one twister yarn processing machine with a maintenance device mounted for movement longitudinally along the machine and to each of the spindle assemblies. The methods include moving a gripper device of a first cleaning device out of the maintenance device and into the protective pot of the selected spindle assembly for gripping and moving the protective pot out of the spindle assembly and into the maintenance device, while cleaning the protective pot in the maintenance device and then returning the protective pot to the spindle assembly. When the balloon limiter is also cleaned, a second cleaning device is moved out of the maintenance device and into the balloon limiter device of the spindle assembly while the protective pot has been removed and is being cleaned in the maintenance device. The balloon limiter is cleaned by the second cleaning device in the spindle assembly and the second cleaning device is then returned to the maintenance device and the gripper device of the first cleaning device then returns the cleaned protective pot to the spindle…
