They tried hand cutting with a toothed blade but the teeth get caught in the canvas threads and tear it. I have a sawzall but I don't know if the blade speed will be fast enough to overcome the pull of the threads. Is there a non-toothed way to cut this? The rolls are 12 feet long now and quite heavy, 2-3 people to lift, so a floor solution would be best.

I have two suggestions: first, sell it, and buy something suitable. Second, there are industrial converters who have the equipment to unroll it, slit to width, and roll it back up. This is a fair l’y common need, but the sewn product industry in the US is pretty dead, so unless you’re in ny or LA, there’s unlikely to be something local. 

  Trying to do this with a saw will be a disaster.
