ABSTRACT:
A process and apparatus for the control of a yarn storage mechanism on a spinning mill machine is proposed. When yarns are wound up it may occur, e.g. in forming conical bobbins, that more yarn is delivered than is wound up. The yarn which is briefly in excess is here taken up in form of a yarn loop by a compensator arm which intervenes transversely in the course of the yarn and is mounted so as to be capable of swivelling. According to the invention it is proposed that the compensator arm be subjected to the force of a spring which acts upon it increasingly as the yarn loop decreases, and in that the force of an additional elastic element acts upon the compensator arm as further excursion occurs.
