    摘要： An object of the present invention is to suppress yarn swing and the increase in power consumption in a spun yarn drawing apparatus.
    A spun yarn drawing apparatus 3 includes three or more heating rollers 31 and a thermal insulation box 13 housing these heating rollers 31. A yarn Y is wound onto the three or more heating rollers 31 at a winding angle of less than 360 degrees, and these heating rollers 31 are configured to heat and send the yarn Y to the downstream side in a yarn running direction. The three or more heating rollers 31 include a first heating roller 32, a second heating roller 33, and a third heating roller 34. The thermal insulation box 13 includes a circulator 50 which is provided around the second heating roller 33 and which is configured to cause a roller accompanied flow generated by rotation of the second heating roller 33 to circulate around the entire second heating roller 33 in its circumferential direction.

    摘要： The invention relates to a device for producing a tow from a plurality of extruded fiber bundles, comprising multiple melt spinning stations arranged in a row. Each melt spinning station has a spinneret for extruding one of the fiber bundles, wherein multiple preparation devices and a draw-off device for drawing and combining all the fiber bundles are associated with the melt spinning stations. The extruded fiber strands are cooled below the melt spinning station by means of multiple blowing tubes which are connected to a cooling conducting device. The aim of the invention is to obtain a constant individual setting of the cooling air flow per melt spinning station. According to the invention, this is achieved in that the cooling conducting device consists of multiple controllable cooling air stations for generating multiple cooling air flows, said cooling air stations being connected to at least one of the blowing tubes independently of one another.
