Abstract
A cooling system for filament bundles, which are spun from polymer melt by at least two spinneret units ( ) disposed one beside the other and are drawn off by a draw-off system ( ), the filament bundles ( ) 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 ( ).
