English to Spanish Tech/Engineering Paper / Paper Manufacturing converting lines

I have a list of terms related to a converting line for paper production, the list goes:
cut supply Trim Cutter
cut supply Core Saw
cut supply General Line
cut supply Embosser
cut supply Log Accumulator
cut supply Banner Saw
cut supply Core Banner

It's just an excel list, so no other context whatsoever, everything is clear, I know what a log is, and what a trimmer does and what saw means, it's just the word banner in this list I cannot get. Does banner have a meaning I am not quite well recalling? Any idea? Thank you!
