摘要： A yarn pooling roller (51) includes a yarn pooling section (52), a first tapering section (58) that widens from a base end section (52a) of the yarn pooling section (52) towards the yarn supplying device side by a first inclination angle (θ1), and a second tapering section (59) that widens from the first tapering section (58) towards the yarn supplying device side by a second inclination angle (θ2) that is smaller than the first inclination angle (θ1). The second tapering section (59) receives the guided spun yarn (Y) and prevents an end of the spun yarn Y from moving towards the tip end section (52b) side of the yarn pooling section (52) at a breakage of the spun yarn Y. The first tapering section (58) guides the spun yarn (Y) received by the second tapering section (59) to the base end section (52a).

摘要： A spinning machine includes a yarn forming unit configured to form yarn from a spun material, a winding device configured to wind yarn formed by the yarn forming unit, a tension detecting unit configured to detect the tension of yarn in an upstream side from the winding device in a direction in which the yarn travels, and a control unit configured to control the yarn forming unit based on a result of detection by the tension detecting unit such that the yarn is wound onto the winding device with adjustment of the tension added to the spun material in the yarn forming unit. The control unit adjusts the tension by controlling a device of the yarn forming unit disposed at least in an upstream side or in a downstream side from a position at which the spun material is twisted in the direction in which the yarn travel.
