Abstract (en)

[origin: EP1258546A2] Twisted thread is drawn back off the winding bobbin (S), until a thread section is reached in which the twist is intact. This section is fixed and parted, behind the fixing point with respect to the winding bobbin. The parting location assures sufficient thread length for mechanical- or hand knotting or splicing, to allow connection with the end from the twisting spindle. Twist spindle operation is resumed with a time delay in take-up, allowing for appropriate twist as the thread section between joining- and fixing points runs through. Preferred Features: A central controller (C) delays winding spool start up as the twist spindle runs up. The delay takes into consideration: spindle rotation speed, twist per meter and run-up time of the spindle.
