Embodiment Construction

[0024] exist figure 1 A side view of an apparatus for producing spunbonded nonwoven fabrics according to the present invention is shown in .

[0025] A spinning beam (not shown here) and a blowing device are integrated in the pivoting unit 1 in such a way that the filament curtain 8 is delivered on the underside of the pivoting unit 1 . The filaments 8 impinge on the mesh / sieve belt 4 , which is driven by a drive 10 . Due to the high speed at which the filaments 8 impinge on the mesh belt 4, a planar configuration is produced, which is carried away by the mesh belt 4 as a spunbonded nonwoven fabric 9 and delivered to another processing device ( not shown here). Below the point at which the filaments 8 impinge on the mesh belt 4 , a suction box 5 is arranged which is displaceable in the conveying direction of the mesh belt 4 . For this purpose, the suction box is mounted on a support 14 which is connected to the suction structure 15 . Thus, on the one hand, the area of ​​lo...

Abstract

An apparatus is configured to produce a spunbonded fabric. In order to achieve an airiness of the spunbonded fabric and ready adaptability to process parameters which are to be changed, a spinning beam together with a blowing apparatus is configured to be pivotable in a pivoting unit. A relatively high airiness is achieved by the filaments running obliquely onto the fabric belt below the spinning beam. Rotary leadthroughs or elastic feed lines to the spinning beam make the slight pivoting possible.

Description

technical field [0001] The invention relates to an apparatus for producing spunbond nonwovens according to the preamble of claim 1 . Background technique [0002] During the production of the nonwoven fabric according to the invention, a plurality of filaments are extruded from a polymer melt, formed into a flat structure on an air-permeable mesh belt / sieve belt and simultaneously transported away by the mesh belt. Such a device is described in patent document DE 199 13 162 C1. [0003] Here, the molten polymer fed by the extruder is first spun into a plurality of slivers through single or multi-row linearly arranged spinning holes in the spinning beam, and after coming out of the spinning holes, it is then passed through The air stream fed by the nozzle breaks up into fine filaments of finite length. [0004] The filaments exit the air nozzles at high speed and impinge on a mesh belt arranged at a defined distance, where the filaments form a flat structure. The filaments...
