Abstract
Fiber waste generated during operation of a circular machine is removed from components of the machine and/or an associated creel by air currents that conduct the fiber waste to one or more filters. Air suction and/or air jet forces remove the fiber waste from the filters. In one embodiment the waste removing apparatus includes stationary air suction and/or air jet devices that remove the fiber waste from a rotating filter. In another embodiment the air suction and air jet devices rotate and the filter is stationary.
