ABSTRACT:
An open end rotor for a spinning machine generally comprises a rotary chamber with an open end and an opposite closed end, a first annular wall extending from the open end radially outwardly from a rotational axis and toward the closed end, and a second annular wall extending from the closed end radially outwardly from the rotational axis and toward the first wall to define a fibre collecting space. The first wall comprises an inner portion forming an angle of 55.degree. to 75.degree. with a horizontal plane, and an outer portion. A straight line extending from the outer portion forms an angle of 10.degree. to 35.degree. with the inner portion. The second wall comprises an inner portion extending from the closed end, and an outer portion forming an angle of 20.degree. to 50.degree. with a straight line extending from the inner portion of the second wall. The outer portions of the first and second wall define therebetween the fibre collecting space.
