ABSTRACT:
The invention is concerned with a textile spinning machine particularly a ring spinning machine, and is directed to the provision of a tension reliever between the delivery rollers and the yarn balloon, which has the effect of producing a tension differential between the yarn forming the balloon, and the yarn travelling from the delivery rollers to the tension reliever. In order to facilitate piecing-up of the yarn after a breakage, the tension reliever has a drive wharf and a capstan device which includes a yarn engaging capstan element, the capstan device permitting threading in a radial direction, and having a snap-in connection with the wharf, so that the capstan device can be completely detached from the drive wharf for a piecing-up operation. The tension reliever itself has a hollow body rotatable about an axis substantially coincident with the path of the yarn and a capstan element in the form of a rod having a yarn engaging section extending close to the axis of rotation and a hook portion at the distal end to prevent the yarn sliding off the yarn engaging section.
