Abstract
A method for providing a multifilament bundle of melt spun polymer filaments that includes providing a spinning device including at least M extruders for melting M polymers, M groups of spinning stations, each group comprising N spinning stations, each spinning station comprising a spin pack coupled to a spin pump which receives molten polymer from one of the M extruders and spins a strand of filaments by pushing said polymer through the coupled spin pack, and N transformation stations for bundling M strands of filaments. The method further includes spinning N*M strands of filaments from the spinning stations at a given spin pump output and bundling the strands into N multifilament bundles via the N transformation stations whereby the spin pump outputs are varied over time.
