ABSTRACT:
A drying apparatus includes a thermal roll for contacting and heating aluminum web in a continuous sheet form. The thermal roll includes a roll surface, having a static friction coefficient μ defined by contact with the web. The static friction coefficient μ satisfies a condition of:in-line-formulae description="In-line Formulae" end="lead"?t+V≦Gin-line-formulae description="In-line Formulae" end="tail"?whereinG=μ·σA⁢1=μ·t·sin⁡(θ/2)where t is tension applied to the web;G is roll retaining force with which the roll surface frictionally retains the web;V is thermal expansion force generated by thermal expansion of the web retained on the roll surface;σA1is pressing force caused by the tension to the web and applied to the roll surface by the web;θ is a wrap angle at which the web contacts the roll surface.Thus, distortion of the web can be prevented even with a great difference in the temperature from the thermal roll.
