Abstract

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

First claim

What is claimed is:

1. A glass article layer comprising:
two glass articles extending in a z-direction and arranged side by side in an x-direction;
two spacer positions are provided spaced apart at an interval A in the z-direction longitudinally of the two glass articles; and
spacers are arranged between the two glass articles, wherein the spacers are thread-like elements, wherein at least one of the thread-like elements is provided at each of the two spacer positions, wherein only one of the thread-like elements is provided at each of the two spacer positions, and wherein the only one of the thread-like elements includes a loop in a y-direction below or above the two glass articles.

2. The glass article layer of claim 1 , wherein the thread-like element is at least partially wrapped around every glass article at the two spacer positions.

3. The glass article layer of claim 1 , wherein each of the thread-like elements has two thread sections interposed between the two glass articles at each of the two spacer positions.

4. The glass article layer of claim 1 , wherein the glass articles are glass tubes or glass rods.

5. The glass article layer of claim 1 , wherein each of the thread-like elements has a thread thickness S where 0.25 mm≤S≤2.5 mm.

6. The glass article layer of claim 1 , wherein each of the thread-like elements is made of a plastic material.

7. The glass article layer of claim 6 , wherein the plastic material is 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).

8. The glass article layer of claim 1 , wherein the two spacer positions are provided at intervals between 20 cm and 80 cm.

9. The glass article layer of claim 1 , wherein the only one of the thread-like elements has two thread sections interposed between the two glass articles at each of the two spacer positions.

10. The glass article layer of claim 9 , wherein the two thread sections extend at an angle α relative to the z-direction, with 80°≤α≤100°.

11. The glass article layer of claim 9 , wherein each thread section of the two thread sections is wrapped around at least 5% of the outer circumference of one of the two glass articles.

12. The glass article layer of claim 9 , wherein each thread section of the two thread sections is juxtaposed in the z-direction.

13. The glass article layer of claim 1 , wherein the only one of the thread-like elements is wrapped around at least 70% of the outer circumference of the two glass articles.

14. The glass article layer of claim 1 , wherein two thread-like elements is provided at each of the two spacer positions, the two-thread like elements comprising a first thread-like element and a second thread-like element.

15. The glass article layer of claim 14 , wherein the first thread-like element has one thread section and the second thread-like element has another thread section.

16. The glass article layer of claim 15 , wherein the thread section of the first and second thread-like elements form an interlace between the two glass articles.

17. The glass article layer of claim 15 , wherein the thread section of the first and second thread-like elements form a knotted interlace between the two glass articles.

18. The glass article layer of claim 14 , wherein the first thread-like element is wrapped around an upper half of an outer circumference of two glass articles and the second thread-like element is wrapped around a lower half of the outer circumference.

19. A glass article bundle comprising two glass article layers as claimed in claim 1 , the two glass article layers being arranged on top of each other in a y-direction, wherein the two glass article layers are arranged offset one above the other.

20. The glass article bundle of claim 19 , wherein the thread-like elements of the glass article layers are spacers between the two glass article layers.

21. The glass article bundle of claim 19 , further comprising a cover sheath at least at both ends.

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