Abstract
Operatively connected with a spinning ring of a ring spinning or ring twisting machine is a tubular inner ring at a small distance, the upper limit or boundary of such inner ring being located at a higher position than the traveller guide surface defined on the spinning ring, in such a manner that unthreading of the thread, which no longer is tensioned by the traveller is rendered impossible. Also the inner ring and/or the spinning ring are provided with at least one slot-opening by means of which traveller debris can escape. Furthermore the distance of the outer upper edge of the inner ring from the traveller guide surface is to be chosen sufficiently large, so that upon restarting of the winding process the traveller does not collide with the inner ring.
Claims10
An inner ring arrangement for a spinning ring of ring spinning or ring twisting machines, comprising:
- an inner ring arranged substantially coaxially within the spinning ring so as to maintain therebetween a gapforming clearance;
- said spinning ring having an upper traveller guide surface structured for taking-up an inner traveller leg of a traveller, said inner traveller leg extending downwardly and outwardly;
- said inner ring having an upper end serving to support an untensioned thread,
- said upper end of the inner ring being located at a higher position than a lower limit of the traveller guide surface for said traveller leg on the spinning ring;
- and
- at least one substantially slot-shaped opening extending in circumferential direction provided for one of said rings.
