A method for transferring a yarn after a yarn break to a normal yarn travel position at a textile machine winding station including making a yarn connection between a yarn supply point and a takeup bobbin and subsequently transferring the yarn to the normal yarn travel position at a transfer point at the reciprocating yarn guide with a tranfer motion of a yarn transfer device of a device that re-establishes yarn travel. The chronological course of the making of the yarn connection and the transverse motion of the yarn guide are monitored. The tranfer motion of the yarn transfer device and the transverse motion of the yarn guide are adapted to one another as a function of the chronological course for causing the yarn and the yarn guide to substantially simultaneously arriving at the transfer point. An apparatus for performing the method includes a first device for monitoring reciprocation of the yarn guide to a yarn tranfer point. A second device detects and processes signals from the first device and ascertains the time remaining for the guide to reach the transfer point. A third device which re-establishes a yarn connection has a device for transferring the yarn to the normal yarn travel position at the transfer point and a fourth device for chronologically adapting the making of the yarn connection to the motion of the yarn transfer device and initiating the transfer motion of the yarn transfer device as a function of other signals from the second device.
Method for transferring a yarn after a yarn break to a normal yarn travel position at a textile machine winding station having a reciprocating yarn guide with a transverse motion, which comprises making a yarn connection between a yarn supply point and a takeup bobbin, providing an apparatus that re-establishes yarn travel with a yarn transfer device movably mounted thereon, subsequently transferring the yarn to the normal yarn travel position at a transfer point at the reciprocating yarn guide with a transfer motion of the yarn transfer device, monitoring the chronological course of the making of the yarn connection and the transverse motion of the yarn guide, and adapting the transfer motion of the yarn transfer device at the transfer point to the transverse motion of the yarn guide as a function of the time required by the machine for making a yarn connection and of the time required by the machine during the transfer motion of the yarn transfer device and the time remaining before the arrival of the yarn guide at the transfer point for causing the yarn and the yarn guide to substantially simultaneously arrive at the transfer point of the yarn.
In a textile machine having a winding station with a yarn supply point, a takeup bobbin, and a reciprocating yarn guide for the takeup bobbin, an apparatus for transferring a yarn to a normal yarn travel position after a yarn break, comprising first means for monitoring reciprocation of the yarn guide to a yarn transfer point and issuing signals;
