I have two Rota-Trim units in my darkroom for cutting roll paper. One is set-up for colour paper with a quite impressive cardboard guide system using genuine duct tape, this was for 40cm wide roll paper manufactured in Australia by Kodak. I also acquired some Fuji roll paper, it was 30cm in one box and 8" in another box. The metric paper was Japanese and Australian stock, the imperial paper was presumably for the USA market.
The other unit was set-up for B&W 50cm (I think) roll paper from Agfa Australia, this was RC and a great success. I had a series of cuts set-up allowing me to make three sizes of cut sheet paper.
I believe you will find paper emulsion is quite tough, really tough. One can of course damage it, but my experience is that it takes a hiding.
One just lifts the plastic guide on the Rota-Trim unit, slides the paper in to a pre-arranged stop, places the plastic guide down, then runs the trimming wheel back and forth. Got so good, I could do it with my eyes closed.
I must confess though, I haven't used either for some years as my stock of roll paper eventually finished and I obtained some mountainous supplies of paper from closing shops. One haul was 30x24" paper in 50 sheet boxes by 18 boxes, that was the RA4 colour, you don't wish to know how many B&W boxes I obtained.
