Question Sheets vs Roll Process

Arial - it's almost helvetica
I hold the sheet up and run a single edge razor blade down the edge, the paper is thick enough to guide the blade and only cut off the overhang. When doing rolls, if the laminate is a hair wider than the vinyl, I square one side so the overhang is only on one side of the roll. Once the roll is done, I take a big snap blade knife, extend the blade all the way out and sort of saw off the bit the overhangs. Same deal if it walks. I don't like listening to it squeak across the platen and it can also stick and screw up your cut.

I think most plotters free up or feed out enough ahead of time so that the drag or "stuck togetherness" isn't an issue during the actual cutting.

I hate not having a sheet or roll perfectly centered, but I've only had it be a frustration and not an actual issue. Up to about 1/4" inch I find "safe" for both rolls and sheets, but I aim to have no more than an 1/8th of an inch. Any amount is undesirable obviously.

If it's just a sheet I do sometimes take the time to trim the overhang off before cutting, but rolls I find cursing just as effective.

Have you guys experienced problems with the vinyl curling up as soon as you laminate the vinyl?

This happens with both of my GFP Laminators.

I even loosened the tension to as low as possible and even tightened the rollers 4 inches after they touch/loosened the roller 1 inch up after they touch with no luck.

Do you think this is a machine problem or a laminate problem? We're using Oragaurd 210 but with some suggestions we're planning on testing Oragaurd 215/Substance PL-3150.
