ータ。 Two sheets of plastic film are heated, a sheet to be sealed is sandwiched between the films, and the plastic film is pressed together with the sheet. One roller shaft of a pair of pressure rollers is fixed and the other roller shaft is movable. In the laminator, the movable roller shaft is urged in the direction of the fixed roller shaft by a spring, and the urging pressure can be adjusted by a cam whose rotation is adjusted and set by an externally operable ratchet mechanism. As the ratchet mechanism, a reversible ratchet wheel having a means for switching the direction in which it can rotate is used, and the cam is rotated approximately 90 degrees clockwise and counterclockwise from a predetermined posture, and The movable roller shaft is configured to be at a position farthest from the fixed roller shaft at the end of rotation in one of the clockwise directions, and to be at the closest position at the end of rotation in the other direction. A laminator having a crimping force adjustment device.
