ABSTRACT:
In a process and an arrangement for piecing an air-spun yarn, it is provided that the newly spun yarn end is gripped and is fed to a yarn connecting device, in which case it is brought into the range of action of a yarn storage device which is connected in front of the yarn connecting device. This yarn storage device is able to be activated when the yarn connecting device is operated and to store the then supplied yarn in several loops in such a manner that, during and after the yarn connecting, the continuously supplied yarn is still taken in by the yarn storage device until the excess length of yarn existing between the inlet of the yarn storage device and the partially wound spool is used up by driving the partially wound spool at a winding speed which is higher than the operating speed.
