| titleOfInvention | RING AND RELATED RING RUNNERS |
| abstract | The ring, for a ring spinner or twister, is profiled to form a flange for the traveller to slide round, where the cross section of the flange is an acute-angled triangle towards the inner side of the ring with free corners. The inner laying surface of the flange is at an angle of 70-110 deg. to the horizontal. The traveller is also shaped as an acute-angled triangle, with the ends of the legs bent inwards at an angle, symmetrically, to cover the corners of the triangle contour, the intersection of the base line with the laying surface and the intersection of the base line with the outer surface. The triangular cross section of the flange is an equilateral triangle, for a symmetrical traveller with legs of equal length. The contact lengths of the traveller account for at least 40% of the total length of an extended traveller. The vector of the forces from the yarn on the traveller together with the friction and centrifugal forces passes vertically through the centre of the laying surface contour. The traveller radius where the yarn passes through is max. equal to 3 1/2 times the radius of the spun yarn. The outer surface and the inner laying surface of the flange are cambered, and the traveller legs have a suitable concave shape to fit the surface cambers. The camber at the outer surface of the flange can be increased as a support step for the traveller when it is in an extreme angled setting. The support step with the laying surface run in concave together in the point of the triangular contour. The ring traveller is in the form of an acute-angled triangle, with legs of equal length, and the leg ends are bent symmetrically inwards at an angle. USE/ADVANTAGE - The structured shape of the ring and the traveller gives a matching fit to give optimum running characteristics with lowest possible wear. |
