Electronic roller: shrink the blanket evenly in a careful process. Oil roller: a rougher stretch into place.
Oil practice: keep raising temperature and keep stretching at max tension. The blanket gets narrower and longer. Micro-adjust so it rolls in the middle.
At 200 °C the client can press a test and continue. If power is lost mid-process, start over.
This stretch-into-shape practice is not for electronic roller heat presses; those frames are not firm enough for constant rising tension.
