ABSTRACT:
A thread breakage repair apparatus for use in open-end spinning machines includes a fixture which holds the thread and trims its broken end and it also includes a movable assembly, on which a drawoff tube is mounted which is connected to a source of suction. This drawoff tube is brought close to the end of the thread held by the clamping and severing fixture, whereupon a controller releases the clamped thread which is then aspirated into the interior of the drawoff tube. The mechanical transport mechanism for the thread may be reversed in motion by the controller, permitting already spun thread to be backspaced so that the end of the thread may be reattached to the fibers located in the spinning rotor. The drawoff tube may also be of the telescoping type whose extension is determined by the controller.
