Abstract

A glass article layer is provided that includes at least two cylindrical glass articles arranged side by side in an x-direction and extending in a z-direction. Spacers are arranged between the cylindrical glass articles. The spacers are provided at least at two spaced apart spacer positions in the z-direction longitudinally of the cylindrical glass article. The spacers are thread-like elements and at least one thread-like element is provided at each position.

First claim

What is claimed is:

1. A glass article layer comprising:
two glass articles arranged side by side in an x-direction and extending in a z-direction; and
spacers disposed between the two glass articles, the spacers being provided at two spaced-apart spacer positions in the z-direction longitudinally of the two glass articles, wherein the spacers are thread-like elements, and wherein only one thread-like element is provided at each of the two spaced-apart spacer positions without completely encircling an outer circumference of the two glass articles and contacts 40% to 80% of the outer circumference of both of the two glass articles.

2. The glass article layer of claim 1 , wherein the thread-like elements are at least partially wrapped around the two glass articles.

3. The glass article layer of claim 1 , wherein one thread-like element is provided at each of the two spaced-apart spacer positions.

4. The glass article layer of claim 3 , wherein, at each of the two spaced-apart spacer positions, the thread-like element is arranged such that the thread-like element is wrapped around the two glass articles along an equal outer circumferential area thereby forming wraps, and a loop is provided between the two glass articles.

5. The glass article layer of claim 4 , wherein the loop extends in a y-direction beyond a line that connects centers of the two glass articles.

6. The glass article layer of claim 4 , wherein the loop comprises a first upreaching loop section and a second upreaching loop section which are interconnected by a third loop section.

7. The glass article layer of claim 6 , wherein the first and second loop sections are disposed offset to one another in the z-direction.

8. The glass article layer of claim 1 , wherein the thread-like element has a first end and a second end, wherein each of the first and second ends is connected to a last wrap through a connecting section.

9. The glass article layer of claim 8 , wherein the connecting section rests on an upper side of the glass article layer and extends in the x-direction over the glass article layer.

10. The glass article layer of claim 1 , wherein the thread-like elements comprise a first thread-like element and a second thread-like element at each of the two spaced-apart spacer positions.

11. The glass article layer of claim 10 , wherein the first and second thread-like elements are wrapped around the two glass articles alternately along an upper side and a lower side thereof.

12. The glass article layer of claim 10 , wherein the two glass articles are wrapped by the first thread-like element along an upper side thereof, thereby defining upper wraps, and by the second thread-like element along a lower side thereof, thereby defining lower wraps, and alternately thereto are wrapped by the first thread-like element along the lower side thereof, thereby defining lower wraps, and by the second thread-like element along the upper side thereof, thereby defining upper wraps.

13. The glass article layer of claim 12 , wherein each thread-like element has a first end and a second end, wherein the first ends are connected to one another and the second ends are connected to one another.

14. The glass article layer of claim 13 , wherein the ends are connected to one another by thermal fusing, gluing, or by mechanical connection.

15. The glass article layer of claim 1 , wherein the thread-like element has a thread thickness S, with 0.25 mm≤S≤2.5 mm.

16. The glass article layer of claim 1 , wherein the thread-like element is made of a plastic material selected from a group consisting of polypropylene (PP), polyethylene (PE), high-density polyethylene (HDPE), polyethylene wax, polyamide (PA), styrene-acrylonitrile copolymer (SAN), polyester, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyurethane (PU), acrylonitrile-butadiene-styrene copolymer (ABS), polyether ether ketone (PEEK), and polycarbonate (PC).

17. The glass article layer of claim 1 , wherein the two glass articles are glass tubes and/or glass rods.

18. The glass article layer of claim 1 , wherein the two spaced-apart spacer positions are arranged at intervals A 1 , A 2 with values between 20 cm and 80 cm.

19. A glass article bundle, comprising at least two glass article layers of claim 1 , which are arranged on top of each other in a y-direction, wherein the glass article layers are disposed such that the glass articles are arranged in close packing.

20. The glass article bundle of claim 19 , further comprising a cover sheath at least at the ends thereof.

21. The glass article bundle of claim 20 , wherein the cover sheath is a shrink film.

22. A glass article layer comprising:
two glass articles arranged side by side in an x-direction and extending in a z-direction; and
spacers disposed between the two glass articles, the spacers being provided at two spaced-apart spacer positions in the z-direction longitudinally of the two glass articles, wherein the spacers are thread-like elements, and wherein at least one of the thread-like elements is provided at each of the two spaced-apart spacer positions, wherein one thread-like element is provided at each of the two spaced-apart spacer positions, and wherein, at each of the two spaced-apart spacer positions, the thread-like element is arranged such that the thread-like element is wrapped around the two glass articles along an equal outer circumferential area thereby forming wraps, and a loop is provided between the two glass articles.

23. A glass article layer comprising:
two glass articles arranged side by side in an x-direction and extending in a z-direction; and
spacers disposed between the two glass articles, the spacers being provided at two spaced-apart spacer positions in the z-direction longitudinally of the two glass articles, wherein the spacers are thread-like elements, and wherein one thread-like element is provided at each of the two spaced-apart spacer positions, and wherein each of the thread-like elements has a first end and a second end, wherein each of the first and second ends is connected to a last wrap through a connecting section.

24. A glass article layer comprising:
two glass articles arranged side by side in an x-direction and extending in a z-direction;
a first thread-like element at a first position in the z-direction, the first thread-like element is a first continuous element that is positioned between the two glass articles at the first position without completely encircling an outer circumference of the two glass articles; and
a second thread-like element at a second position in the z-direction, the second position being spaced in the z-direction from the first position, the second thread-like element is a second continuous element that is positioned between the two glass articles at the second position without completely encircling the outer circumference of the two glass articles,
wherein the first and second thread-like elements contact 40% to 80% of the outer circumference of each of the two glass articles; and
wherein the first thread-like element is an only thread-like element at the first position and the second thread-like element is an only thread-like element at the second position.

25. The glass article layer of claim 24 , wherein the first thread-like element extends between the two glass articles in the z-direction.

26. The glass article layer of claim 24 , wherein the two glass a
