Abstract
A heating roll press machine according to the present disclosure includes a pair of rollers and a preheating unit that preheats a processing object before the processing object is conveyed to the pair of rollers. The preheating unit preheats the processing object so that a temperature distribution differs according to positions in a width direction of the processing object to reduce a temperature difference in the width direction of the processing object after the processing object passes through the pair of rollers each having a temperature difference between a roller central part and roller end parts.
