Abstract
The present invention relates to a laminator and a method for controlling the heating rollers of the laminator. In the preheating stage, the rotational directions of the heating rollers are reverse to those during the heating and pressing operation. As a consequence, the article fails to be transported across the region between the heating rollers before the heating and pressing operation is performed.
