Method of respinning using ancillary yarn

A method of respinning using an attending device on an operating unit of an open-end spinning machine having a spinning unit, after replacement of a full bobbin by an empty tube using, for respinning, an ancillary yarn from an ancillary yarn unwinding means mounted on the attending device, the ancillary yarn having a beginning and the operating unit having a winding device for winding yarn on an empty tube, the method comprising the steps, in sequence, of:

• displacing the beginning of said ancillary yarn toward the winding device;
• fixing the beginning of said ancillary yarn at a point in said winding device for winding on an empty tube at a location on the tube for enabling removal of the ancillary yarn winding from the empty tube before a completion of respinning on the tube;
• metering a predetermined length of the ancillary yarn from the point of its fixing in the winding device, by unwinding the ancillary yarn from the unwinding means, the ancillary yarn being led from the point of its fixing in the winding device in the direction of the spinning unit;
• at the latest after the above steps have been carried out, inserting an empty tube into the winding device and fixing the ancillary yarn to the tube;
• after the above steps have been carried out, severing the ancillary yarn at a further point established by the metering of said predetermined length of the ancillary yarn between said fixing point of the ancillary yarn in the winding device and the unwinding means of the ancillary yarn, thus creating a spinning-in end of the ancillary yarn and at the same time also a new beginning of the ancillary yarn situated on the unwinding means of the ancillary yarn, while the empty tube in the winding device contains no turns of ancillary yarn because the tube has not yet begun to rotate, with the empty tube in a stopped state;
• moving the created spinning-in end of the ancillary yarn into the spinning unit for respinning, the first mentioned beginning of the ancillary yarn being fixed on the tube in the winding device;
• and
• resuming a spinning connected with the beginning of the yarn winding on the tube in the winding device, before this time, no ancillary yarn having been wound on the tube.
