ABSTRACT:
A thread-tying device for a spinning frame has a yarn locating head which locates the broken end of the yarn on the spool and is connected by a transmission which transmits the movement of the drive shaft to the disengaged spool. The broken end of the yarn is recovered and retained while the transfer mechanism conveys the yarn into the proximity of the turbine outlet. The mechanism has guide means determining the trajectory of the head between a position in which the transmission member is simultaneously adjacent the spool and the drive shaft, and the position in which the yarn retained on the head is carried substantially to the level of the turbine outlet.
