- the invention relates to a method for the parallel production of a plurality of fiber strips, in particular a plurality of filter tow strips, according to the preamble of claim 1 and an apparatus for carrying out this method according to the preamble of claim 11.
- EP 0 629 722 A1 describes such a filter tow of crosslinked filaments or fibers, such as those made of cellulose acetate, for example, used in the production of cigarette filters.
- a filter tow made of cellulose acetate typically consists of more than 1,000 filaments which are formed with fine spray nozzles of acetate flakes dissolved essentially in acetone and initially present as uncrimped fiber strips, each with longitudinally aligned filaments.
- Their required for use in cigarette filters mechanical stability and the necessary draw resistance receive these fiber strips only by a crimping, in which the linearly arranged filaments are zigzag shaped in a so-called compression channel to crimped fiber strips with a substantially constant and symmetric Kösel characterizing over the entire fiber strip cross-section;
- Typical parameters for describing the crimp characteristic are the crimp index (number of crimps per length of filter tow) and the degree of crosslinking (number of entanglements between crimped adjacent filaments per length of filter tow).
- the crimped filter tow strips or filter strands thus obtained have a constant total weight (weight per meter of uncrimped filter tow length) and show uniform crosslinking or entanglement under the filaments over the entire strip width. To provide for further use, they are usually stored in a storage container, pressed and packaged as a bale.
- EP 0 629 722 A1 teaches a more efficient production of a filter tow of crimped, cross-linked filaments of the aforementioned type, which is made possible by producing several filter tows in parallel in the same apparatus, the filter tows produced in parallel extending in the longitudinal direction of the stripe extending predetermined tear lines, which have a lower degree of crosslinking compared to the respective filter body, so that initially a so-called multi-wide fiber strip is formed.
- Such a multiple-width fiber strip is characterized by its further processability in conventional processing devices, in particular in double filter extruders with single processing part, and leads there to a considerable reduction in set-up costs by providing several filter tow strips at a time and in a defined manner with a filter towball and separating can be done easily and reliably on the separation of the predetermined tear lines.
