Patent ID: 7313908

Claim:
A disintegration apparatus for textile machines, including open end spinning machines, the apparatus defining longitudinal, transverse, and clockwise directions, the apparatus comprising: a plurality of teeth located upon the apparatus and connected along the longitudinal direction with a predetermined tooth spacing L z , each of said plurality of teeth having an apex and a base, and defining a first section facing along the longitudinal direction of motion and positioned contiguous to said apex, said first section being positioned at a predetermined angle W B from the transverse direction, wherein said angle W B as measured in the clockwise direction is greater than, or equal to, about 0 degrees; and a second section facing along the longitudinal direction of motion and positioned contiguous to said base, said second section being positioned at a predetermined angle W S from the transverse direction, wherein said angle W S as measured in a counter-clockwise direction is greater than 0 degrees, and a rounding section positioned between said first section and said second section; wherein said rounding section defines a tangential coalescing point as the outermost longitudinal point of said rounding section that is tangent to the transverse direction; wherein the distance between said tangential coalescing point and said apex defines an effective tooth height H t ; wherein each of said plurality of teeth defines a tooth base having a height H F , and wherein the ratio of said effective tooth height H t to said height H F of said tooth base is between about 0.2 and 1.5.
