Definitions

  • the invention relates to a melt spinning apparatus for producing a plurality of multifilament yarns according to the preamble of claim 1.
  • a generic melt spinning apparatus is known from WO 2004/074155 known.
  • melt spinning devices For the production of synthetic threads, such melt spinning devices are combined in a plurality to a complete spinning plant in a machine shop. Here, a high space utilization is desired. The greater the number of installed melt spinning devices, the higher the production output of the spinning plant. In addition to the machine division of the melt spinning devices, the productivity is essentially determined by the number of threads that can be produced per melt spinning device. In that regard, there is a desire to form melt spinning devices as compact as possible with the largest possible number of threads.
  • a spinning device In the generic melt spinning device, a spinning device, a cooling device, a drawing device and a winding device are arranged to one another to a vertical yarn path. Since the spinning device with the spinnerets, the treatment device with the godet units and the winding device with the winding stations each require different distances between the parallel guided yarns, spreading or merging of the threads are unavoidable. However, within the yarn sheet, it is desired that each of the multifilament yarns produced in the melt spinning apparatus have substantially identical properties. Therefore, deflections and spreads that are too different Thread tensions in the multifilament threads lead to avoid as possible.
  • a deflection device and a vertically oriented guide roller are therefore used in the transfer of the threads from the treatment device to the winding points of the winding device in order to obtain as compact as possible thread guide by a plurality of deflections.
