    Jan 01, 2012·Control of end breakage rate at ring frame is the first step for improving ring frame productivity. It not only leads to ends down loss but also restricts spindle speed. Ends-down denotes those spindles where end has broken and is waiting for piecer to mendit. Ends-down loss is given by: d= e X 0.75t. Where, d = ends down %

    Ringchromosomes: vicious circles at the end and beginning

    Mechanisms of ring formation. Ring chromosomes may be formed in two ways (Fig. 1): Figure 1 : Ring chromosome formation may occur through breaks in the chromosome arms and fusion of the proximal broken ends, leading to loss of distal material (a). Rings may also be formed by telomere dysfunction triggering fusion of reactive chromosome ends without major loss of genetic material (b).
