Abstract

In a spinning apparatus (2) including spinning units (20), both a material cost of a supplying unit (32) and the increase in power consumption are suppressed. A spinning apparatus (2) of the present invention includes spinning units (20). Each of the spinning units (20) includes: a heating box (21) to which a spinning pack (22) is attached; a piping (241) in which molten polymer flows toward the spinning pack (22) in the heating box (21); a gear pump (25) which is provided at the piping (241) and which is a target of maintenance; a cooled unit (X) which is provided upstream of the gear pump (25) in the piping (241) in a flow direction (A), the cooled unit (X) being cooled so as to decrease a flow rate of the molten polymer flowing in the cooled unit (X); a cooling unit (31) which defines a cooling space (V) in contact with the cooled unit X; and a housing (29) which accommodates the heating box (21). The cooling unit (31) includes an upper end (31a) to which a supplying unit (32) including a supplying path for supplying air functioning as a refrigerant is attachable and from which the supplying unit (32) is detachable. Each of the spinning units (20) is structured so that, when the supplying unit (32) is attached to the upper end (31a), the supplying path is connected to the cooling space (V). The upper end 31a does not protrude as compared to an outer surface of the housing (29).
