Abstract

A glass roll, as well as a device and a method for manufacturing the glass roll are provided. The glass roll includes a glass ribbon having a thickness, a length in an x-direction, and a width in a y-direction. The glass ribbon has at least one defect site at a position, as well as at least one error mark disposed on the glass ribbon, and is wound up into a glass roll.

First claim

The invention claimed is:

1. A glass roll comprising:
a glass ribbon having a thickness, a length in an x-direction, and a width in a y-direction, the glass ribbon having at least one defect site at a position defined in the x and y directions, the glass ribbon being wound up into a roll, the glass roll having at least one error mark that identifies the position of the defect site and has a plurality of equidistant positional marks disposed along a lengthwise edge and within the width of the glass ribbon, the plurality of equidistant positional marks comprising information on a location in the x-direction of each of the plurality of positional marks.

2. The glass roll of claim 1 , wherein the glass roll comprises a use region distanced in the y-direction from a lengthwise edge, the position being in the use region.

3. The glass roll of claim 1 , wherein the at least one error mark identifies the position in the x-direction of the glass ribbon of the defect site.

4. The glass roll of claim 1 , wherein the glass ribbon comprises at least one lengthwise edge extending along the x-direction, an edge region that extends from the lengthwise edge in the y-direction, and a use region connected to the edge region.

5. The glass roll of claim 1 , wherein the error mark is disposed in a strip along the x-direction.

6. The glass roll of claim 1 , wherein the error mark comprises information on the position, an error type of the defect site, and a size of the defect site.

7. The glass roll of claim 1 , wherein at least one of the plurality of positional marks has readable information on the position of the defect site relative to the positional mark.

8. The glass roll of claim 1 , wherein the plurality of positional marks and/or the at least one error mark comprise marks selected from the group consisting of laser engraved marks, sticker marks, laser-assisted diffused ink marks, ink imprint marks, and machine-readable marks.

9. The glass roll of claim 2 , wherein the at least one defect site in the use region is protected by a protector that is disposed locally on the defect site.

10. The glass roll of claim 9 , wherein the protector comprises a layer of a UV-cured coating or UV-cured adhesive.

11. The glass roll of claim 9 , wherein the protector is disposed only on a convex outer side of the roll.

12. The glass roll of claim 1 , further comprising a separating layer between layers of the roll, wherein the at least one error mark is disposed on the separating layer.

13. A product comprising the glass roll of claim 1 and a data record unambiguously assigned to the glass roll, the data record having at least information on the position of the at least one defect site.

14. The product of claim 13 , wherein the data record is found on a data medium or on the glass ribbon.

15. A glass roll comprising:
a glass ribbon having a thickness, a length in an x-direction, and a width in a y-direction, the glass ribbon having at least one defect site at a position defined in the x and y directions, the glass ribbon being wound up into a roll, the glass roll having at least one error mark that identifies the position of the defect site; and
a plurality of equidistant positional marks disposed along a lengthwise edge, wherein at least one of the plurality of positional marks has readable information on the position of the defect site relative to the positional mark.

16. A glass roll comprising:
a glass ribbon having a thickness, a length in an x-direction, and a width in a y-direction, the glass ribbon having at least one defect site at a position defined in the x and y directions, the glass ribbon being wound up into a roll, the glass roll having at least one error mark that identifies the position of the defect site,
wherein the glass roll comprises a use region distanced in the y-direction from a lengthwise edge, the position being in the use region,
wherein the at least one defect site in the use region is protected by a protector that is disposed locally on the defect site, and
wherein the protector is disposed only on a convex outer side of the roll.
