Abstract
A laminator comprises first and second rollers mounted in parallel for counter-rotation. One of the rollers is supported on a pair of pneumatic cylinders, which can be operated to adjust the gap between the rollers. When a desired gap is reached for the thickness of workpiece to be laminated, locks can be operated to prevent further movement of the first roller towards the second roller. Preferably the locks do not prevent movement of the first roller away from the second roller. After the locks have been engaged to protect the workpiece against crushing, the pressure applied to the first roller during the laminating process can be changed.
