Definitions
- spunbonded nonwovens suitable devices
- starting materials are thermoplastic polymers used that melted to fine Spun threads are spun.
- the spun threads are mostly stretched aerodynamically and thereby obtain the desired strength.
- the threads are deposited after the spinning process or under Interposition of coils on a storage belt on which they come to lie on top of each other and form the spunbond.
- DE-AS 1 303 569 describes a process for producing nonwovens known in which the spun threads are guided through a channel be stretched aerodynamically there and then on one perforated, moving pad in fleece form.
- a turbulence zone is provided below the air duct Cross-threading supported.
- the result is a very irregular one Fleece image.
- a high uniformity of the spunbond is achieved that several guide channels are provided in succession and the resulting channels protruding layers of thread in layers one above the other to form a fleece be filed.
- the spinning beam together with the thread take-off device rotatable train should also eliminate the disadvantages that the So-called curtain procedures occur and in certain areas can lead to overlays of individual filaments.
- the nonwoven has a preferred strength in Longitudinal direction, i.e. in the direction of production, while the strength values in Transverse direction are lower. Due to the inclination of the spinning beam together with the laying and stretching device, this should be compensated.
- the invention has for its object a method with associated Device to produce a spunbond with the very one high uniformity of the fleece structure and basis weight distribution can be achieved.
- the Strength in the transverse direction should, for example, be the same as the strength in Longitudinal direction.
- the invention is based on a method for producing a Spunbonded nonwoven by spinning a parallel one next to the other linear thread array in the form of a curtain from a variety of Spin capillaries with aerodynamic pulling and stretching of the Yarn sheet.
- the stretching channel emerging or withdrawn from a spool of thread from an air stream moved laterally with periodically changing directions, the Air flow seen in a horizontal plane at an angle to the thread sheet is alternately aligned. Individual air blasts in changing directions cause the coulter to move back and forth across the production direction is moved, which leads to the desired fleece structure, for example one high uniformity in structure.
- the air flows can be carried out alternately from left and right. It turned out to be favorable if between the individual air flows Air breaks are inserted, where there is no air blast and the one between the air blasts a vertical alignment of the thread sheet allow.
- the general direction of air flow is perpendicular to the Thread cluster directed. This is a blow-out angle in the horizontal plane selected from 15 °. Other discharge angles are as needed of course possible.

- the roller in turn is in a longitudinal channel filled with compressed air arranged, which is connected to a compressed air reservoir.
- the rotating roller has the advantage that even with larger ones Production widths a uniform pressure at the nozzles over the entire Production range is pending.
- blow-out angles of the nozzles of both rows of nozzles are preferably the same, which means that the thread array has the same design in both directions is achieved.
- the blow-out angles are 10 to 60 °, preferably 45 °.
- an adjustable mechanical air duct to control the Direction of air flow may be provided below the Blasschachtes.
- This air flow can pivotable wing flaps or consist of Coander shells, through which the thread sheet moves back and forth in the production direction can be.
- the preferred embodiment provides opposite the blow shaft on the other front of the thread group Attach air baffle adjustable to blow duct direction. Because of this Air baffle supports the direction of lateral air flow and the lateral pivoting movement of the thread sheet can be stronger or less strong can be adjusted by moving the air baffle closer to the blow duct is introduced or removed from it.
