ABSTRACT:
A method and apparatus for sequentially applying suction and auxiliary yarn to a yarn package of a textile spinning machine. The apparatus is operable to position yarn extending from a tube during a restarting operation in which the winding the yarn is restarted after the occurrence of a break in yarn being fed from a drafting device onto a tube. The apparatus includes a support assembly which supports a suction applying device as well as an auxiliary yarn length delivery device for simultaneous lateral movement of the two devices toward a tube from which a trailing end of wound yarn is to be drawn. The apparatus also includes a control device for controlling the suction applying device to initially apply suction to the tube for predetermined length of time to thereby draw in a trailing end of wound yarn and, if a trailing end of wound yarn is not drawn in, to control the auxiliary yarn length delivery device to deliver a length of auxiliary yarn onto the tube. The apparatus also includes an assembly for either the suction applying device or the auxiliary yarn length delivery device to a yarn extending position at which the extending yarn can be engaged by, for example, a conventional yarn end engaging device, for transfer of the yarn to a piecing location for piecing with the yarn extending from the drafting device.
