(54) SPINNING WINDING SYSTEM AND YARN-THREADING ASSIST UNIT


(57) [Problem to be Solved] To provide a spinning winding system capable of facilitating yarn threading work, and a yarn-threading assist unit capable of facilitating yarn threading work performed at the spinning winding system.
[Solution to Problem] Provided is a spinning unit (2) configured to spin molten polymer (P) downward from a spinneret (24); a cooling unit (5) arranged below the spinning unit (2), including a spinning cylinder (50) for allowing the molten polymer (P) spun from the spinneret (24) to pass therethrough, so as to cool and solidify the molten polymer (P) thereby to form a yarn (Y); a moving mechanism (6) capable of causing the spinning cylinder (50) to move closer to and away from the spinning unit (2); and a yarn-threading assist unit (60) for assisting in yarn threading work of threading the molten polymer (P) through the spinning cylinder (50). The yarn-threading assist unit (60) is attached pressed against an outlet portion (56) for the yarn (Y) so that the spinning cylinder (50) has a negative pressure formed therewithin.
