Abstract: A rotating cylindrical treatment apparatus includes a cylindrical body rotatably supported in the treatment apparatus; a feeding section for supplying a treated material onto an outer circumferential surface of the cylindrical body; a pressure roller for pressing the supplied treated material and for rolling the pressed treated material; a first medium introducing device for introducing a heating or cooling medium into the cylindrical body and for discharging the introduced medium; a second medium introducing device for introducing the medium into the pressure roller and for discharging the introduced medium; and an endless belt for conveying the rolled treated material while causing the rolled treated material to be closely contacted with the outer circumferential surface.

Abstract: A rotating cylindrical treatment apparatus for accomplishing rolling and heat-treatment of a treated material continuously and with high reliability. The apparatus includes a deviation detecting device provided at a suitable position for detecting deviation of an endless belt to generate a signal and an axis inclination structure for varying an inclination of at least one of belt support rollers depending upon the signal generated from the deviation detecting device, so that the deviation may be automatically corrected without interrupting the operation of the apparatus.

Abstract: A rotating-drum heat treatment apparatus for carrying out cooling or heating of a material to a desired temperature. The apparatus includes two drums arranged in a casing adjacent to each other for continuously cooling or heating the material to be heat-treated, to thereby increase a time required for the heat treatment of the material.
