Abstract

The disclosure concerns a method, an apparatus and a system for producing or equipping paperboard such that information carriers can be implanted between two layers of material, together with a piece of paperboard material produced in this way and a package. In particular, the disclosure concerns the implantation of an information carrier in corrugated paperboard, taking into account cuts that are subsequently to be made in the transverse direction, the distance of the position at which the cross-cuts are made from the position at which the information carriers are applied, and the movement executed by the web of material between the application position and the cross-cutting position.

Claims

1. A method of producing paperboard or a web of paperboard material, the method comprising joining at least two layers of material together, the joining including positioning and implanting an information carrier between the at least two layers of material and providing at least one outer surface of the paperboard or of the web of paperboard material with a marking that indicates the x- and y-positions of the internally disposed implanted information carrier, wherein positioning the information carrier comprises moving an application head that applies the information carrier transversely to a direction of travel of the corrugated paperboard as it moves longitudinally past a first position at which the information carrier is applied, the providing of the marking including positioning the marking using data and control variables that have been used for the positioning and the implanting of the information carrier.

2. The method of claim 1, further comprising applying the information carrier to a layer of material carrying said information carrier before said layer of material is joined to another layer of material covering said information carrier.

3. The method of claim 1, further comprising severing the paperboard or the web of material in the transverse x-direction to singulate said paperboard or said web of material into pieces of material after all said layers of material have been joined together.

4. The method of claim 3, further comprising moving the layers of material in the longitudinal direction and applying the information carrier to a carrying layer in a time-controlled manner at positions relative to the longitudinal extent of said layer of material, the application taking into account

predefined cuts that are to be made in the transverse direction,

the distance of the position at which cross-cuts are made from the position at which said information carriers are applied, and

the movement executed by the paperboard or the web of material between the application position and the cross-cutting position.

5. The method of claim 1, wherein the information carrier is a device from which information can be read by electromagnetic radiation, acoustomagnetic radiation, radiofrequency waves, of ultrasonic waves.

6. The method of claim 1, wherein the information carrier is an RFID transponder or an EAS tag.

7. A method for producing paperboard or a web of paperboard material that comprises a first layer and a second layer, the method comprising:

applying an information carrier to a first web as it moves longitudinally past a first position, wherein applying the information carrier comprises moving an application head that applies the information carrier transversely to a direction of travel of the first web as it moves longitudinally past the first position;

after the information carrier is applied to the first web, uniting the first web with a second web, the first and second webs thereby each forming a respective of the first and second layers of the paperboard or the web of paperboard material, the uniting implanting the information carrier between the first and second layers; and

after the information carrier is applied to the first web, applying a marking to an outer surface of the paperboard or of the web of paperboard material, wherein the marking is positioned to indicate the position of the information carrier between the first and second layers of the paperboard or the web of paperboard material.

8. The method of claim 7, wherein:

applying the information carrier to the first web comprises a control system receiving control data and using the control data to position the application of the information carrier; and

applying the marking to the outer surface comprises using the same control data to position the marking.

9. The method of claim 7, wherein applying the marking comprise applying a colored marking.

10. The method of claim 7, wherein applying the information carrier to the first web comprises applying the information carrier to a glued surface of a single-face web.

11. The method of claim 7, wherein:

the information carrier is applied to the first web downstream of a glue machine and upstream of a laminating station; and

the uniting of the first web with a second web comprises laminating the first web to a second web at the laminating station.

12. The method of claim 7, further comprising drying the paperboard or the web of paperboard material in an heating and stretching area after the uniting of the first web with a second web but before the application of the marking.

13. The method of claim 7, wherein the applying of the marking occurs after the uniting of the first web with the second web.

14. A method comprising:

producing corrugated paperboard comprising a cover layer, a second layer, and an RFID tag contained between the cover layer and second layer and thereby implanted within the corrugated paperboard, the producing of the corrugated paperboard comprising

applying an RFID tag to one of the cover layer and the second layer of the corrugated paperboard as it moves longitudinally past a first position, wherein applying the RFID tag comprises moving an application head that applies the RFID tag transversely to a direction of travel of the corrugated paperboard as it moves longitudinally past the first position, and

downstream of the first position and after application of the RFID tag, applying a marking to an outer surface of the cover layer, the marking indicating the longitudinal and lateral position of the implanted RFID tag between the cover layer and second layer.

15. The method of claim 14, further comprising moving a second application head that applies a second RFID tag independently of the application head.

16. The method of claim 14, wherein:

the first position is downstream of a glue machine and upstream of a laminating station; and

the method further comprises laminating the cover layer and the second layer at the laminating station.

17. The method of claim 16, further comprising drying the paperboard or the of paperboard material in an heating and stretching area after laminating the cover layer and the second layer but before the application of the marking.

18. The method of claim 14, further comprising:

orienting a corrugated paperboard blank relative to the RFID tag using the marking; and

cutting the thus oriented corrugated paperboard blank.

19. The method of claim 14, wherein:

applying the RFID tag comprises a control system receiving control data and using the control data to position the application of the RFID tag; and

applying the marking to the outer surface of the cover layer comprises using the same control data.
