(54) YARN SPINNING SYSTEM


(57) A slow cooling space is allowed to be changed in length in the up-down direction when the number of yarns spun out is large, with a small number of members. A yarn spinning system 1 includes a spinning apparatus 2 including spinnerets 13, a cooling apparatus 3 configured to cool yarns Y spun out from the spinnerets 13, and a slow cooling unit 4 provided between the spinning apparatus 2 and the cooling apparatus 3 in the up-down direction. The cooling apparatus 3 includes cooling cylinders 21 that are arranged to guide cooling wind to the yarns Y. The slow cooling unit 4 includes a block member 30 and an adjustment unit 40. The block member 30 includes surrounding faces 33 arranged to surround at least parts in the up-down direction of the respective cooling cylinders 21, the surrounding faces 33 have parts above the cooling cylinders 21, and the parts form slow cooling spaces Ss in which slow cooling of the yarns Y is performed. The adjustment unit 40 is arranged to be able to adjust the relative positions of the block member 30 and the cooling cylinders 21 in the up-down direction.
