Abstract (en)
[origin: US6652255B1] A cooling system for filament bundles, which are spun from polymer melt by at least two spinneret units (1) disposed one beside the other and are drawn off by a draw-off system (17), the filament bundles (3a, 3) being cooled in a three-part shaft (A, B, C) by an equidirectional air stream, and the cross-section of the individual shaft parts (A and B) tapering such that the flow rate of the air increases approximately to the same extent as the draw-off speed of the filament bundles (3a, 3).
