Danish to English Tech/Engineering Manufacturing roller process

Hi,
In a short instruction about a manufacturing machine involving rollers and a cutting table, these two sentences appeared "Monter tvaertiveren igen. Nu skulle man i teorien kunne startet maskinen op uden at skulle stille pa valserne.".
I've looked in several Danish dictionaries and can't find this word.
I'm afraid I have no more context than this other than a French reference document called "Rouleaux profilés".
Any ideas would be welcome.
Thanks in advance,
Paul
