| 摘要 |
The invention relates to a cooling system for filament bundles which are melt-spun from a polymer melt by means of at least two adjacent spinneret units (1) and which are discharged by a discharge system (17). The filament bundles (3a, 3) are cooled in a tripartite shaft (A, B, C) using an air current that goes into the same direction as the filament bundles. The cross-section of the individual shaft components (A and B) tapers in such a way that the flow rate of the air increases similarly to the discharge rate of the filament bundles (3a, 3). |
