Definitions
- the present invention relates to a manufacturing method for a tubular
- Element in particular for a filter element for motor vehicles, z. B. as a cabin air filter or intake air filter. Furthermore, the invention relates to a device for producing a corresponding filter element.
- Filter elements are used to filter fluid flows or gaseous media, for example, for filtering an air flow, which is supplied to the vehicle interior or the engine of a motor vehicle.
- the present invention and the problems underlying it are described below essentially for a filter element for filtering air for the interior of a motor vehicle.
- Such filters are also referred to below as a cabin interior air filter or cabin filter or cabin air filter.
- Desirable is also an inexpensive production of appropriate filter.
- the present invention seeks to provide a method and an apparatus for producing a loop-shaped filter element.
- a method for producing a tubular element which may in particular be a filter element for a motor vehicle, comprises the steps of: forming a tubular base element of filter material. Folding the filter material at at least two first portions of a common first circumferential line in the direction of a central axis of the base member by at least two, preferably opposing, first folding knife for generating first circumferential folds.
- the second sections are shifted relative to the first sections on the respective circumferential line.
- a tubular base member which, for example, by a provided filter material sheet whose two opposite edges are joined together processed.
- the base element essentially corresponds to a hose made of filter material into which no folds have yet been embossed. It is also possible vorzu to treat the filter material sheet vorzu by impressing predetermined folds and / or wrinkle orientations for the circumferential or upsetting folds.
- circumferential fold lines are made on parallel circumferential lines.
- the circumferential fold lines may, but need not, be made at regular intervals along the central axis of the base or even finished filter element on the surface of the tubular base element.

- the folding takes place in the direction of the central axis, through which at least two first folding blades for generating third circumferential folds.
- the third sections are shifted relative to the second sections on the respective circumferential line.
- the displacement or rotation of the third sections relative to the second sections can be adjusted, for example, via the set angle of a corresponding production device.
- the set angle is a measure of the rotation of the first and second Faltmesser arrangementsn against each other.
- first and second folding knife are first and second folding knives. Because the first folding knife can be performed on the second folding blades outside of the base member along the central axis over. By leading the folding knife, so a reduction in the distance along the longitudinal or central axis between the folding blades of different rates, arise, for example, the compression folds, which then by a suitable holding device, such as a foam block, the inwardly directed circumferential folds holds, be fixed.
- Corresponding folding knife are thus used alternately as a folding means and as a holding means.
- the tubular base member is provided from the outside with convolutions and simultaneously conveyed along the longitudinal axis of the device.
- At least one of the folder blade sets is slidably disposed along the longitudinal axis.
- the folding knife of a Faltmessersatzes can be moved against each other by a predetermined blade angle around the longitudinal axis.
- the number of folding knives per folding knife set should be at least two.
- the device may also include actuators for moving the folding blades radially with respect to the longitudinal axis. It is possible to control the actuators such that the folding blades of a respective Faltmessersatzes are simultaneously moved radially.
- Filter element further comprises a control device which controls the movements of the folding knife so that a manufacturing method as described above, is performed.
