Abstract
Means and method are disclosed to clean the fiber collection groove of an open end rotor's cup by use of a flexible member rotated about the groove and counterrotated in the opposite rotational sense, it being the changeovers or reversals in rotational directions which apply through the tip of the flexible member the cleaning force at the points of changeover at the groove which effect the cleaning of accumulations of foreign matter. These changeovers are effected by changing relative rotation and counter rotation between the rotor cup and the flexible end member, and are controlled by a programmable control means which may include a microprocessor working through one or more motors, one of which may be a stepped motor of high torque values and occupying but little space.
