Abstract: The invention concerns a spinning machine having a spindle with which to rotate a yarn package, a winding apparatus to wind the yarn on the package, and drafting rolls to feed the yarn to the winding apparatus. According to the disclosed method, the winding down of the yarn on the package is achieved by reversing the rotation of the spindle relative to the spinning direction. according to the disclosed device, a spacer ring is employed which is fixed to the spindle, and which has an upper and a lower hollow, a protruding edge, and substantially sharp edges which aid in cutting the yarn.

Abstract: Improvements to a spinning system (10) having a rotary balloon checking device (16), the checking device (16) consisting of an upper cylindrical portion (27) and lower frustum-shaped portion (28) which surround a yarn package (14) being formed, the upper portion (27) being upheld by a support (17) with bearings which is solidly fixed to a rail (19) of a spinning machine, the yarn (22) on arrival from a drafting unit (20) of the spinning machine forming a balloon between a thread eye (21) and the top of the checking device (16) and thereafter constituting an inner controlled segment (125) and an outer segment (225) able to slide on the checking device (16) during its descent to be wound on the yarn package (14), the yarn (22) being guided (29) at the lower edge of the frustum-shaped portion (28), the improvements comprising:the outer slidable segment (225) of yarn positioned in correspondence with the upper part of the upper cylindrical portion (27) of the checking device (16), andan element (31) to guide the

Abstract: An invention for spinning with a balloon controlled by a checking device is disclosed. The invention is set in rotation by a spindle by means of a yarn, comprising the arrangement of a segment of free yarn constituting a balloon having a controlled and constant height and diameter of base and also comprising the arrangement of a guided segment of yarn downstream of the segment constituting the balloon. Also, the invention is for spinning with a rotary balloon-checking device, comprising a rotary checking device positioned about a yarn package and a tube and having a rotatably supported upper portion and a lower portion performing the function of distributing the yarn on the yarn package, wherein the checking device is open at its upper end and has a pre-determined diameter to contact the yarn.
