Mechanics of high speed texturing. Part II. Theoretical analysis of ring twisting

Abstract

The mechanics of ring twisting are analyzed, and the effects of machine operating parameters such as the R/Y ratio (the ratio of the linear speed of ring to the speed of the yarn path), the ring crossing angle, and the externally applied pressure are discussed. The advantages of the ring twister are compared with the stacked disc spindle and the belt twister. The restraints in designing the ring aggregate are discussed in terms of the differential relative torsional slippage
