Abstract
In yarn processing stations, in which two yarns are withdrawn from feed yarn packages inserted on a package adapter, the problem arises that a residual yarn wind is left on the tube of a feed yarn package. To remove this residual yarn wind, the maintenance and servicing device of the present invention is provided witha rotatable, upward and downward movable gripper for the removal of the package adapter from the yarn processing station, at least one rotatably supported mandrel to receive the package adapter, a rotatably supported, upward and downward movable cutting device for severing a residual yarn wind left on a feed yarn tube, and a rotatably supported suction device for the removal of the cut residual yarn, so as to be able to perform, according to the method of the present invention, the cleaning of feed yarn tubes still carrying yarn remnants directly after their removal from the yarn processing station.
