摘要：A device for forming a yarn reserve on a bobbin tube during the winding operation includes an arm turnable about an axis transverse to the axis of the bobbin tube. The arm engages during its turning in one direction with its hooked end the yarn so that the yarn is wound in one direction on one end of the bobbin tube and a catch member on the arm engages during the turning thereof in this one direction a surface of a disc rotating about an axis parallel to the tube axis, which surface is inclined to the axis of rotation of the disc so that during such rotation the arm is turned in the opposite direction causing corresponding winding of the yarn at the one end of the bobbin tube. A yarn reserve is thus formed at the one end of the bobbin tube in which a plurality of turns are wound in one direction and a following plurality of turns is wound in the opposite direction extending over the first-mentioned turns. The bobbin tube is mounted on support tiltable between a winding position and a release position and the textile machine is also provided with a yarn tension sensor cooperating with a cutter to cut the yarn when the tension thereof slackens. The sensor is rendered inoperative when the tube support is tilted to the release position and rendered operative after a new bobbin tube on the support is placed in winding position.
