摘要：
A rapid warm-up and cool-down pressure roll assembly is provided and includes (a) a rotatable pressure roll including a cylindrical sleeve having an outer surface, and an inner surface defining a hollow interior to the rotatable pressure roll; (b) a thermoelectric assembly sheet positioned within the hollow interior and having a first substrate facing the inner surface of the cylindrical sleeve, a second substrate, an electric current flow path therethrough, and electric current input and output terminals associated with the electric current flow path; and (c) an electric current input switching device connected to the electric current input and output terminals for enabling selective reversing of a direction of electric current flow through the electric current flow path, thereby reversing which of the first substrate and the second substrate of the thermoelectric assembly sheet is hot and which is cold, and therefore selectively enabling a rapid warm-up or rapid cool-down of the cylindrical sleeve of the pressure roll.
