CONSTITUTION: An assembling type drilled roll includes a cylindrical body, the first and second ends(200,500) mounted at both ends of the cylindrical body, a mounting section(300) and an end section(400). The first end(200) mounted on both sides of the cylindrical body is formed with a hollow portion(201) so that a rotary joint of a calendar machine is inserted into the hollow portion(201). The assembling type drilled roll is rotated at a predetermined speed and the joint is maintained in a fixed state. An inlet pipe(2a) and an outlet pipe(2b) are formed at the joint. The inlet pipe(2a) is coupled to an inlet passage(401) so as to supply thermal medium into the mounting section(300).
