Abstract
A bundle of tubular and/or rod-shaped glass articles is provided that includes a longest dimension, a plurality of layers (NL) of the glass articles, and a thread-like element. The longest dimension extends in a first direction. The glass articles in each layer are arranged side by side in a second direction. The plurality of layers are arranged side by side in a third direction. The first, second, and third directions being perpendicular to one another. The thread-like element is around two of the glass articles in at least one layer so that the two glass articles are spaced apart.
