Greg - Yes, the main meaning of the German verb walzen is "to roll". In this context it is used in Modern German to describe industrial processes (e.g. Walzwerk = rolling mill). Secondary meanings are "to dance the waltz" and "to hike, tramp, wander".

Modern German verb walzen derives from Middle High German walzen and Late Old High German walzan, with the meaning of "to roll, rotate".

Back later if I find out anything about Mechthild (presumably *not* the medieval nun from Magdeburg who wrote that beautiful music !) and slang meanings or any references to the song.

What an interesting question, Bob.
Bis spaeter !
