  • the nozzle block assembly consists of a middle and two outer nozzle blocks, which are arranged on the left and right of the middle nozzle block and usually connect directly to the middle nozzle block.
  • the nozzle block aggregate or the middle nozzle block and the outer nozzle blocks expediently extend over the entire tool width or working width.
  • Working width or tool width here means the extent of the device transversely to the conveying direction of a fiber product produced, in particular to the conveying direction of a nonwoven web or a spunbonded web produced. It is within the scope of the invention that the width of an outer nozzle block in the conveying direction is 0.3 times to 4 times the width of the central nozzle block.
  • the device according to the invention can have one or more inflow channels for each component of the multicomponent fibers, in particular the bicomponent fibers, wherein the plurality of inflow channels are then distributed over the working width of the device.
  • a clothes hanger distributor for each component is provided at the nozzle-side end of the nozzle block assembly, which expediently extends over the entire tool width or working width. But it is also possible to use over the working width or tool width several hanger distributor for each component.
  • the nozzle has one or more rows of nozzle openings extending over the working width or tool width.
  • a preferred embodiment which is of very particular importance in the context of the invention, is characterized in that a first inflow channel in the region of the melt inlet runs exclusively through the first outer (left) nozzle block and that a second inflow channel in the region of the melt inlet exclusively through the second outer ( right) nozzle block runs.
  • at least one inflow channel extends over a length of 0.5 to 5 times the diameter of the inflow channel in front of the clothes hanger distributor in the parting plane of the nozzle block parts.
  • a preferred embodiment of the invention is characterized in that vertical bores are introduced for heat insulation in the middle nozzle block and that these bores are distributed over the entire working width. It is within the scope of the invention that the holes are filled with a heat-insulating medium, preferably with air. Conveniently, the vertical bores extend over at least part of the vertical height h of the central nozzle block.
  • the vertical height h of a nozzle block or of the nozzle block assembly relates to the orientation of the nozzle block assembly, in which the melt inlets are arranged at the top and the nozzle or nozzle orifices are arranged at the bottom.
  • heating means for setting desired heating temperatures are arranged in the middle nozzle block and / or in at least one of the two outer nozzle blocks.
  • such heaters are provided in each of the two outer nozzle blocks.
  • heating cartridges are arranged in corresponding bores in the nozzle block.
  • a plurality of heaters arranged in a nozzle block are distributed over the working width or tool width of the device. It is within the scope of the invention that at least one heating device is arranged next to an inflow channel in at least one outer nozzle block.
  • at least one such heating device is arranged next to the inflow channel of this nozzle block.
  • the at least one heating device is preferably arranged in each case on the outer side of the outer nozzle block, d. H. on the side facing away from the middle nozzle block side of the inflow channel.
  • the temperature of the melt can be adjusted specifically in an inflow channel. For example, a temperature of about 280 ° C can be maintained for a polyester melt in the respective inflow channel.
  • the nozzle is a meltblown nozzle. With the device fibers are then produced by the meltblown process.
  • the nozzle is a spinneret for producing filaments for a spunbonded web. Then you can work with the device according to the spunlaid method.
  • the invention is based on the finding that due to the inventive design of the device, a surprisingly homogeneous temperature distribution in the melt streams of the two components can be ensured. As a result, in each case a very uniform flow of the melt streams is achieved in the inflow channels. The skilled person must be particularly surprised that the known from the prior art disadvantages can be eliminated with such simple and inexpensive means. In principle, it is sufficient if in the context of the invention the melt streams or the inflow channels extend only in the melt inlet region exclusively through an outer nozzle block.
  • the figures show a device for producing bicomponent fibers.
  • the device comprises a nozzle block assembly 1, which in the embodiment of a central nozzle block 2 and two outer nozzle blocks 3, 4, namely a left nozzle block 3 and a right nozzle block 4th consists.
