1. A method for unpacking a bundle of tubular and/or rod-shaped glass articles, comprising:
holding the bundle in a locked position; and
pulling a thread-like element that is wrapped around at least two of the glass articles so that the thread-like element is withdrawn from the bundle,
wherein the thread-like element has a minimum cross section (cr), wherein the thread-like element is wrapped around the glass articles at a plurality of different spaced positions (nt) along the length of the glass articles, wherein the plurality of different spaced positions and the minimum cross section are selected according to:
 
 
 
 CR - value
 
 Less than 6000 . . . 12000 . . . More than
NL 3000 12000 20000 20000
 
Less than 8 nt ≥ 2, nt ≥ 2, nt ≥ 3, nt ≥ 4,
 
 ct ≥ 0.5 mm ct ≥ 0.5 mm ct ≥ 0.9 mm ct ≥ 1.0 mm
8 to 12 nt ≥ 2, nt ≥ 2, nt ≥ 3, nt ≥ 4,
 
 ct ≥ 0.6 mm ct ≥ 0.6 mm ct ≥ 1.0 mm ct ≥ 1.1 mm
More than 12 nt ≥ 3, nt ≥ 3, nt ≥ 3, nt ≥ 4,
 
 ct ≥ 0.7 mm ct ≥ 0.7 mm ct ≥ 1.1 mm ct ≥ 1.2 mm
 
wherein the CR-value corresponds to:

OG Complex Work Unit Math
wherein l corresponds to the length of the glass articles in mm,
wherein do corresponds to an outer diameter of the glass articles in mm,
wherein tw corresponds to a wall thickness of the glass articles in mm, the wall thickness of a rod-shaped article being equal to one half of the outer diameter,
wherein the plurality of different spaced positions and the minimum cross section are selected according to:
