- a preferred embodiment runs an inflow channel in the area of the melt inlet exclusively by the associated outer nozzle block.
- Preferably runs at least one inflow channel over a length of 0.5 to 5 times the diameter of the inflow channel before the Clothes hanger distributor in the parting plane of the nozzle block parts.
- a preferred embodiment of the invention is characterized characterized in that in the middle nozzle block cavities are introduced for thermal insulation and that these cavities distributed over the entire working width. It is within the scope of the invention that the cavities with a heat-insulating medium, preferably filled with air are. Appropriately, it is the cavities to drill holes that cover at least part of vertical height h of the central nozzle block extend. Conveniently, the holes are as vertical Drilled holes in the middle nozzle block introduced. Vertical height h of a nozzle block or of the nozzle block aggregate Incidentally, this refers to the orientation of the Nozzle block aggregates, in which the melt entrances above are arranged and the nozzle or the nozzle openings below are arranged.
- heaters for adjustment desired heating temperatures arranged in the middle nozzle block and / or in at least one of both outer nozzle blocks.
- a plurality of heaters arranged in a nozzle block the working width or tool width of the device distributed. It is within the scope of the invention that in at least one outer nozzle block at least one heating device is arranged next to an inflow channel.
- the at least one heating device preferably each on the outside of the outer nozzle block arranged, d. H. at the middle nozzle block opposite side of the inflow channel.
- Heaters can increase the temperature of the melt in one Inflow channel can be adjusted specifically. So, for example a temperature of about 280 ° C for a polyester melt maintained in the respective inflow channel become.
- the invention is at the nozzle around a meltblown nozzle. With the device then fibers can be produced by the meltblown process.
- the Nozzle around a spinneret for producing filaments for a Spunbond is the Nozzle around a spinneret for producing filaments for a Spunbond. Then, with the device after the Spunlaid method to be worked.
- 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 the two components can be ensured. As a result, in each of the inflow channels a very achieved uniform flow of the melt streams. The Specialist must be particularly surprised that from the Prior art known disadvantages with such a simple and little expensive means can be eliminated. Basically, it is sufficient if within the scope of the invention the melt streams or the inflow channels only in Melt inlet area exclusively by an outer Run nozzle block.
- the figures show a device for the production of Bi-component fibers.
- the device has a nozzle block assembly 1, which in the embodiment of a middle nozzle block 2 and two outer nozzle blocks 3, 4, namely a left nozzle block 3 and a right nozzle block 4 exists.
- the nozzle blocks 2, 3, 4 close directly to each other and extend over the entire working width or tool width of the device.
- Working width or tool width means the extent the device perpendicular to the conveying direction F or in Figs. 1 and 2 perpendicular to the paper plane.
- conveying direction refers to the promotion of a generated Fiber product, for example, the conveying direction of a Nonwoven web.
- nozzle block unit 1 In the nozzle block unit 1, two inflow channels 5, 6 arranged in each case for a melt stream 7, 8 of a component. At the lower end of the nozzle block assembly 1 is a Nozzle 9 with openings 10 for dispensing the bicomponent fibers arranged. A series of such openings 10 extends over the entire working width of the device. In the embodiment 2, several rows extend of openings 10 over the entire working width or tool width.
- the first inflow channel 5 extends over a part its vertical length exclusively by the first outer and left nozzle block 3 and runs the second Inflow channel 6 over a part of its vertical length exclusively through the second outer or right Nozzle block 4.
- Vertical length means the extension an inflow channel 5, 6 in the direction of the vertical height h of the nozzle block assembly 1.
- the distance a of the part of the Inflow channel 5, 6 with the vertical length 1 to the middle Nozzle block 2 at least 0.5 to 5 times the diameter of the inflow channel 5, 6. It is within the scope of the invention, that the width b2 of an outer nozzle block 3, 4, the 0.3-bis 4 times the mean nozzle block 2.
- Figs. 1 and 2 has been indicated that after Preferred embodiment in the middle nozzle block. 2 between the inflow channels 5, 6 vertical holes 11 to Thermal insulation or thermal separation of the two Melt streams 7, 8 are located. Appropriately, these are vertical holes 11 only filled with air. The vertical holes 11 are preferably over the entire Working width of the device distributed.
