Abstract
A hot press device has a pair of hot press rollers for heating and pressing a treatment object therebetween while rotating, and pairs of delivery rollers are arranged before and after the pair of hot press rollers. The treatment object passes back and forth through the pair of hot press rollers, and a controller controls the delivery rollers so that the circumferential speeds of the respective delivery rollers located downstream in the forward or reverse passing direction of the treatment object can be increased.
