We had a job where we needed to laminate about 30 rolls last year.
I bought one of those manual crank hand laminators off eBay for $100 - and then I mounted the roll of premask above the manual laminator. That then fed into the manual laminator... And we put the vinyl through and just rolled the manual laminator.
It worked great - kind of a manual way to do it vs a roll laminator. What helped was we could adjust the pressure on both sides of the roller... So if it started to crinkle due to uneven pressure from too much being cut out of one side, we could loosen it up a bit so it became smooth again and keep going. We'd get 50-75 ft before it'd crinkle, then it'd take a foot or so to become perfect again after we adjusted it. Then we just carefully lifted the crinkled area and fixed it once we were done.
We were using a vinyl with a synthetic backer, which is a pain to premask on our laminator.
So if a real laminator doesn't work, might be worth looking into a manual that's more adjustable
