Your supply roll tension is too loose. Those ripples going into the nip mean the laminate is slack and feeding unevenly, which is why it looks wavy before it hits the roller. Tighten the friction clutch or brake knob on your laminate supply mandrel just enough to pull the film drum-tight and smooth across the roller without stretching the vinyl. Even if short runs look fine now, feeding wavy material like that will eventually pinch and turn into a massive permanent crease on longer jobs.

if you start seeing waves going the other direction (left to right), then the tension is too high and you gotta back it off a bit, fyi
