Abstract
A tool is supported by a support face on the upper side of a spinning or twisting ring, with a bearing face bearing on the outer edge of the ring. A hook engages by a tip below the inner end of a ring traveller, which is brought into a predetermined position by a permanent magnet let into a support part. By actuating the tool, the hook is moved in the direction of the support face, so that it lifts the ring traveller over the inner edge of the ring. After passing over the inner edge and due to its spring action, the expanded ring traveller jumps into a channel, which leads to a collecting container. With such a removal of the ring traveller from the ring, the yarn drawn by the ring traveller remains undamaged.

A method of removing a ring traveller from the ring of a ring-spinning or ring-twisting frame, comprising the steps of:
- positioning a removal member relative to a ring traveller located on the ring;
- manipulating the removal member so as to force one end of the ring traveller over an adjacent edge of a flange of the ring while the other end of the ring traveller is still in engagement with another flange of the ring, in order to thereby expand the ring traveller against its own spring tension;
- releasing said one end of the ring traveller after it has cleared said adjacent edge of the ring, so that the ring traveller springs-off the ring in the direction of a collecting device;
- and
- retaining the released ring traveller in the collecting device after such ring traveller has sprung-off the ring.
A device for removing a ring traveller from the ring of a ring-spinning or ring-twisting frame, comprising:
- handle means containing a first handle part and a second handle part coacting with one another;
- a support part provided for said first handle part;
- said support part having a support surface and being connected with said first handle part;
- movable gripper means arranged in confronting relationship with respect to said support surface and serving for gripping a ring traveller;
- means for pivotably connecting said gripper means with said second handle part for enabling movement thereof relative to and in the direction of said support surface;
- a positioning element for positioning the ring traveller which is to be removed from the ring;
- said positioning element comprising a permanent magnet arranged at said support part;
- means defining a collecting container having a collecting opening for receiving the ring traveller which has been removed from the ring;
- said movable gripper means comprising a hook-like element;
- and
- said collecting opening of said collecting container being arranged neighboring said support surface.
