Abstract

A paper roll core, which includes a tag and wherein the tag is a tag which is radio-readable and includes a flexible element. The core has its end face provided with a recess with a bottom and a wall, in which the tag is fitted in an at least partially coiled configuration. For example, the tag can be glued in the recess. Alternatively or additionally, the tag can be retained substantially stationary by a springback force evolved as a result of coiling the flexible element, bracing the flexible element against a wall and/or a bottom included in the recess.

Claims

1-11. -11. (canceled)

12. A core with a tag, such as a paper roll core, wherein said tag is a radio-readable tag, preferably a tag comprising a flexible element such as an antenna, and that the core has its end face provided with a recess, which comprises a bottom and a wall and in which said tag is fitted in an at least partially coiled configuration, wherein said recess is either:

a) a hole, which is provided in an end face of the core and which has a diameter smaller than the core wall thickness and which has a center axis substantially co-directional with a longitudinal axis of the core, or

b) a groove, which is provided in an end face of the core and which has a diameter smaller than that of the core'"'"'s outer periphery but larger than that of the core'"'"'s inner periphery, and a center axis of which is substantially common with a longitudinal axis of the core.

13. A core as set forth in claim 12, wherein the tag is retained substantially stationary by a spring back force evolved as a result of coiling said flexible element, thus bracing said flexible element against a wall and/or a bottom included in the recess, and/or wherein the tag has been secured in the recess for example by gluing.

14. A core as set forth in claim 12, wherein an antenna included in the tag is arranged along the tag'"'"'s outer periphery, and wherein the tag'"'"'s middle section is provided with an elongated cut about which the tag is folded into two halves, such that the first half is folded in a first direction and the second half in a second direction which is substantially opposite to the first one.

15. A core as set forth in claim 12, wherein the antenna of a tag included in the core makes up a pattern in the shape of an arc, an ellipse, a circle, or at least a partial circle about the center axis of the recess.

16. A core as set forth in claim 12, wherein said tag is an RFID tag, such as a passive RFID tag operating in the UHF band.

17. A method for the fabrication of a core with a tag, wherein said tag is a tag comprising a flexible element such as an antenna, and wherein the method comprises providing an end face of the core with a recess, which comprises a bottom and a wall and in which said tag is fitted in an at least partially coiled configuration wherein said recess is made either by:

a) providing an end face of the core with a hole, which has a diameter smaller than the core wall thickness and which has a center axis substantially co-directional with a longitudinal axis of the core, or by

b) providing an end face of the core with a groove, which has a diameter smaller than that of the core'"'"'s outer periphery but larger than that of the core'"'"'s inner periphery, and a center axis of which is substantially common with a longitudinal axis of the core.

18. A method as set forth in claim 17, wherein the tag is retained substantially stationary by a spring back force evolved as a result of coiling said flexible element, thus bracing said flexible element against a wall and/or a bottom included in the recess, and/or wherein the tag is secured in the recess for example by gluing.

19. A method as set forth in claim 17, wherein the tag, which comprises an antenna on its outer periphery, has its middle section provided with an elongated cut about which the tag is folded, such that a first half of the cut is folded in a first direction and a second half in a direction which is opposite to the first one.

20. A method as set forth in claim 17, wherein the antenna of a tag included in the core is adapted to make up a pattern in the shape of an arc, an ellipse, a circle, or at least a partial circle about a center axis of the recess as the tag is being fitted in said recess.
