It could be "rope beam". "Baum" appears to be beam.
The German version of Yvonne's first reference talks about "der Rope Dyeing Prozess", so they use the English phrase. Rope dyeing is about dyeing not ropes of the kind used to tie up ships and bondage enthusiasts, but ropes of yarn that are then woven into denim.

Yes, the Zettelbaum is the warp beam.

Rope- und Zettelbäume weft and warp beams?
No idea where the Rope element comes from, though.

It's Ropebaum rather than Rope (hence the hyphen). I don't know if this is a real word. It's about weaving, and I found "warp beam" for Zettelbaum.
