<p>PURPOSE:To perform favorably the covering of a surface, by dividing the circumferential surfaces of a pair of rollers for pinching and delivering a sheet body that includes covering films in layers into a plurality of regions, heating the regions by heating sources, and detecting the temperature of each of said regions of the rollers to control the opeation of said heating sources. CONSTITUTION:Each of the outer circumferential surfaces of the pair of the rotatable rollers 1A, 1B for pinching and delivering the sheet body that includes the covering films in layers is divided along its length into the three regions, i.e. the central region (x) and the end regions (y, z), the central heating source 2Ax, and the end heating sources 2Ay, 2Az are arranged correspondingly to the regions (x, y, z), and a central temperature detector 5x and end temperature detectors 5y, 5z for detecting the temperatures of the regions are arranged so that the temperatures of the regions are controlled to be made equal by the temperature controlling signals from the detectors 5x, 5y, 5z. Thus, uniform heating can be attained, and the covering of a surface can be carried out favorably.</p> |
