Attorney, Agent or Firm: Lerner; Herbert L., Greenberg; Laurence A.
A method of increasing the hairiness and bulkiness of a thread, in an open-end rotor spinning machine having a deflection ring disposed concentric to the axis of rotation of the rotor, includes forming a false twist in the thread with the deflection ring, continuously withdrawing the thread through the deflection ring substantially along the direction of the axis of rotation of the rotor, dissolving the false twist in the thread, forming a thread balloon with the thread, bringing the thread in contact with a multiplicity of separately disposed balloon disturbance elements, and changing the diameter of the thread balloon several times during each revolution of the thread balloon, and a device for carrying out the method. |

DETAILED DESCRIPTION We claim: 1.
Method of increasing the hairiness and bulkiness of a thread, in an open-end rotor spinning machine having a deflection ring disposed concentric to the axis of rotation of the rotor, which comprises continuously withdrawing the thread through the deflection ring substantially along the direction of the axis of rotation of the rotor, forming a thread balloon with the thread having a maximum diameter larger than the inner diameter of the deflection ring, bringing the thread in contact with a multiplicity of separately disposed balloon disturbance elements, and thereby changing the diameter of the thread balloon several times during each revolution of the thread balloon.
2.
Method according to claim 1, which comprises abruptly changing the peripheral velocity of the thread balloon several times during each revolution of the thread balloon.
3.
Method according to claim 1, which comprises alternatingly moving the thread at least to the vicinity of the axis of the thread balloon and back to the outermost edge of the thread balloon, during the formation of the thread balloon.
4.
In a device for increasing the hairiness and bulkiness of a thread in an open-end rotor spinning machine, having a rotor with an axis of rotation and a deflection ring disposed concentric to the axis of rotation of the rotor, the thread being continuously drawn through the deflection ring substantially along the direction of the axis of rotation of the rotor, the improvement comprising a thread balloon guide following said deflection ring for forming a thread balloon having a larger maximum diameter than the inner diameter of said deflection ring, said thread balloon guide having balloon disturbance elements for contacting the thread and changing the diameter of the thread balloon, said balloon disturbance elements being annularly and separately disposed in said thread guide.
5.
Device according to claim 4, including a navel, said deflection ring being disposed in said navel and said thread balloon guide being in the form of a tubular insert disposed in said navel
