Abstract (en)
An object of the present invention is to improve the efficiency in transferring heat from a heated box to a spinning pack and to suppress the heat transfer to the spinning pack in the circumferential direction of the spinning pack from becoming uneven.A melt spinning device 1 includes a cylindrical spinning pack 2 including a spinneret 21, a heated box 3 including a concave portion 32 into an internal space of which the spinning pack 2 is inserted and which is open downward, and a heat conduction mechanism 4 including a separated member 42 which is able to make contact with an outer circumferential surface of the spinning pack 2 inserted into the concave portion 32 and which is separated into plural members with respect to a circumferential direction of the spinning pack 2. When the spinning pack 2 is inserted into the concave portion 32, members which include at least the separated member 42 and which are included in the heat conduction mechanism 4 form a heat conduction path from a wall surface defining the concave portion 32 in the heated box 3 to an outer circumferential surface of the spinning pack 2.
