Definitions
- the invention relates to a turning station for changing the mutual alignment of the functional layers of film webs according to the preamble of claim 1.
- Such turning stations can be used in systems for the production of multilayer film webs, which often have an outer functional layer.
- a system is described for example in DE 296 21 374 U1.
- a blown film extrusion system is shown there, with which a two- or multi-layer film tube can be produced, which has a sticky functional layer on the inside.
- This film tube is used to produce film webs in a suitable manner, here for example by slitting. After reversing, these film webs are wound up into independent coils.
- a functional layer in the sense of the invention is not only limited to a sticky layer, but can be any layer with special properties, for example in terms of color or permeability.
- DE 195 01 668 C1 proposes cutting this film into film webs, one of the to turn both lanes with a specially developed turning device and then to reverse them. In this way it can be ensured that the turned film web is not guided with its adhesive layer along the air turning rods of the take-off device.
- the object of the present invention is to propose a structurally different turning station.
- the proposed turning station has means for guiding a first tubular web, which guide the first web of film to the other side of the plane, which are formed by the extension lines of a second film.
- Winding stations where a reversal of the direction of rotation is necessary are expensive and do not exist in most old systems.
- the winding direction can be carried out on both winding positions reverse without reversing the direction of rotation.
- means for deflecting the first film are also provided on the other side of the plane which is formed by the extension directions of the second film.
- FIG. 1 perspective view of a turning station according to the invention
- FIG. 2 side view of a turning station according to the invention
- FIGS. 1 and 2 show a turning station according to the invention, to which two film webs 2, 3 are fed via different guide rollers 4, which were produced, for example, with the film extrusion and film pull-off device shown in DE 296 21 374 U1.
- the film web 3 is guided in a straight line along its conveying direction z through the turning station.
- the film web 2, which is initially guided above the film web 3, is guided within the turning station 1 via a turning bar 5.
- the turning bar 5 is advantageously arranged parallel to the plane which is defined by the conveying direction z and the direction of extension y of the film web 3 within the turning station 1.
- the turning bar 5 includes an angle of 45 degrees with the conveying direction z. However, the turning bar 5 can also be oriented as desired.
- the film web 2 is then guided over a deflection roller 6, the axis of rotation of which advantageously runs parallel to the conveying direction z.
- the film web 2 is deflected so far that its subsequent conveying direction y is orthogonal to the original conveying direction z and the direction of extension x.
- the film web 2 is again deflected and turned over a further deflection roller 7 and a further turning bar 8 in such a way that its current one Delivery direction z 'runs opposite to the original delivery direction z.
- the film web 2 is now guided below the film web 3.
- a reversing roller 9 can be used. This example is shown in Figure 2.
- the film webs 2, 3 are deflected around the reversing rollers 9, 10 in such a way that they can be fed to the winding devices (not shown) and wound there.
- the film webs 2 and 3 were not turned over, but only interchanged in the y direction.
