Patent ID: 7156639

Claim:
A device for producing filaments across a filament-spinning width, comprising: a distributor connectable to a source of a molten polymer for distributing said molten polymer over a provisional spinning width which can be greater than or less than said filament-spinning width; at least one replaceable distribution plate located downstream of said distributor and provided with a multiplicity of distribution openings in a path of the molten polymer delivered by said distributor and distributed over said filament-spinning width whereby the filament-spinning width can be greater than or less than said provisional spinning width and is selected for said device by selection of the replaceable distribution plate installed in the device; and a replaceable spinneret plate downstream of said distribution plate and formed with spinneret channels and spinneret orifices over said filament-spinning width and defining said filament-spinning width for emitting strands of the molten polymer forming respective filaments, whereby a spinning width B i defined by the distribution openings is smaller or larger than the provisional spinning width B v with the provisional spinning width B v being reduced or enlarged to a final spinning width B e corresponding to the filament-spinning width by selective replacement of said distribution plates.
