有源刷/无源辊

I am not sure of the Chinese term.
活动刷/被动卷

What I remembered from the Expo I attended several years ago is that some type of labelling machines have brushes that will brush the sticker label in a particular motion & direction so that it will attach to the container evenly, w/o bubbles & creases.

I believe its typo 'pasive' , it must be passive roll.
Label comes in the form of a roll 卷, like bathroom toilet paper.
It is held by a roll feeder in a fixed position, one end of the roll is pulled by the machine & cut at the desired position & measurement, then it is attached to the container with the aid of the brushes.

However, w/o picture or detailed description, I can only make a reasonable guess.

Please be reminded that machineries are all electrically operated.
Hope this can help.

刷子是活动的，而滚轮是被动的，这些在机械传动中是很普通的名词。
