Definitions

the invention relates to a device for manufacturing a spunbonded fabric made from bicomponent threads of two different thermoplastics.
the invention has for its object to indicate how a structurally simple device of type mentioned at the beginning.
the invention is based on the knowledge that a known two-channel wide slit tool and can be connected to this via a distributor plate has only holes, a spinneret plate can be connected, which is for nonwoven production desired even bicomponent thread distribution guaranteed.
the distributor plate and the spinneret plate from below with the Screwed wide slot tool.
the spinneret bore in a rectangular, preferably to arrange a square grid.
the device shown in the figure is used for Production of a spunbonded fabric from bicomponent threads of two side by side, different thermoplastic Plastics processed with two extruders become.
Under the wide slot tool 1 is by far a spinneret plate 6 arranged in the longitudinal and transverse directions of the Wide slot tool 1 in a square grid arranged arranged spinneret holes 7.
the Wide slot tool 1 and the spinneret plate 6 is one Intermediate distributor plate 8, the oblique Feed holes 9, 10 for the two plastic melts having.
the distributor plate 8 and the spinneret plate 6 are from below with the help of screws 11 Wide slot tool 1 screwed.
the inlets 12 of the feed holes 9 for one Plastic melt is in the area of one Channel exit slot 4; the inlets are located accordingly 13 of the feed holes 10 for the other plastic melt in the area of the other channel outlet slot 5.
the outlets 14, 15 the feed holes 9, 10 for the two plastic melts in alternating transverse rows 16 and 17.
These outlets 14, 15 are each centrally between four spinneret holes arranged in a grid square 7 arranged so that their entrance cross-section overlap. In this way, the Spinneret bores 7 of two adjacent transverse rows of the between these opening feed holes 9 and 10 with which supplies one plastic melt while the other thermoplastic via the feed holes 10 or 9 of the next transverse row.
the plastics can change the ratio of the two plastics in the bicomponent threads being controlled.
