US 7,182,008 B2 · Sheet material cutting method for cutting thermal imaging material

Abstract

A decurl apparatus includes a heating device to heat an image recording carrier web at a constant temperature, which exceeds the glass transition temperature of a support for a constant time period; and a cooling device for subsequent cooling of the image recording carrier web to a temperature equal to or lower than the glass transition temperature, while the image recording carrier web maintains a predetermined shape. The heating device includes an induction-heated heating roller and holding rollers arranged at arbitrary angular positions with respect to the outer circumference of the heating roller. As a result, the image recording carrier web is reliably decurled by a simple construction without being influenced by a transfer velocity or the like.
