    2. Line B: 1-position POY line for the production of pre-oriented polypropylene multifilament yarn, plant design for parallel spinning, 6 ends/pos.
    3. Line C: 1-position FDY/POY line for the production of fully drawn FDY or pre-oriented POY polypropylene multifilament yarn, plant design for 6 ends/pos.
    4. Plant design preparation for PET POY multifilament spinning if decided at a later time; the required conversion parts are listed on page 10 pos. 6.
  2. Line Configurations
    1. Line A: 1 extruder for 2 positions POY 8 end parallel spinning.
    2. Line B: 1 extruder for 1 position POY 6 end parallel spinning; POY take-up machine with lower and upper godets separately driven for yarn tension settings and yarn relaxation between godets and take-up winder for best bobbin formation.
    3. Line C: 1 extruder for 1 position FDY/POY 6 end spinning.
