Abstract
The travelling piecer carries a lever to separate the nip rollers, a yarn reserve forming device to receive the yarn and a threading device for threading a broken yarn from a package between the nip rolls and through the yarn reserve forming device. The piecer also has a control which effects a piecing operation in which a clutch is actuated to feed fiber into the spinning unit while yarn is back-fed into the unit from the yarn reserve. At the completion of a predetermined time period (T) the nip rolls are re-engaged to withdraw the re-pieced yarn.
