The processed adhesive-bonded fabric for manufacturing multilamellar in combination.
In the embodiment shown in fig. 5, fleece 30 passes through two rollers 48,49 supports, and wherein, compressed part 42 can be with institute
State one of roller 48 or 49 mating reaction.Draw here by the whole width of fabric web pre-tensioned by plastics or gold
Belong to the combination of the sheet material made, adjustable pre-tensioner or bending on the whole width of fabric web for this sheet material will be variable
Pressure be applied on fleece, draw the technical scheme of suitable save space using roller 48 or 49.In this embodiment, set
Portion 43 off-duty because fleece 30 is compacted again by the steering of moveable slewing rollers 54, and then just by
In jet beam 45a and suction section 45b by set.Jet beam 45a preferably with the average pressure duty of 15bar to 80bar so that
Do not wash away the loose fiber on fleece 30.Loose fiber is pressed with fiber matting 30 by slewing rollers 54 simultaneously
Tightly, by means of this slewing rollers, the fiber loosely placed upside down is stacked on fiber matting 30 by forming screens.
Subsequently, just set is occurred by jet beam 45a.
Subsequent bearing 46 for guiding and support belt 55 also has dome 46a here, so as not to damage
Fleece 30.Mobility in removal route or from removal route removal, fleece are moved into by roller 54 and adhered portion 45
30 from carding machine 20 putting into or transferring one side and can more easily design to slanted screen net forming machine 50, and simultaneously to pressure
The magnitude in tight portion.
This embodiment has the advantage that, i.e. fleece 30 alternatively can have set in advance or not have
Contact and pre- with loose fiber (fiber of the wet-laying of slurry or slanted screen net forming machine) in the case of set in advance
Process velocity can be improved during first set, or can alternatively process very light fleece.This embodiment another
Advantage is the probability that fixing apparatus 40 are integrated in slanted screen net forming machine 50, wherein, slewing rollers 54 moveable/pivotably
Arrangement one side to make whole equipment be flexible, on the other hand, the compression of fleece 30 and loose fiber is therefore
