Abstract

PURPOSE: To provide a calender roll excellent in heat exchanging efficiency and adapted to reduce energy loss by a method wherein a means for inducing a rotational flow of a heat-transmitting medium is provided in a passage for the medium provided in the vicinity of the surface of a roll.
CONSTITUTION: For example, the heat-transmitting medium heated by a temperature controller 1 is introduced into a central hole 5 in the interior of a drilled roll on the opposite side of a rotary joint 3 through a supply pipe 2, the rotary joint 3 and an inner pipe 4, and it is fed into a drilled hole 9 beneath the roll surface through a slanted hole 8 to uniformly heat the roll surface. The drilled hole 9 consists of three adjacent hole parts connected in series with each other in the interior of the roll so as to make uniform the temperature distribution of the roll surface. Accordingly, the heat-transmitting medium makes 1.5 reciprocal movements through the body part of the roll and circulates to the temperature controller 1 through a slanted hole 10 on the rotary joint side, the central hole 7, the joint 3 and a discharge pipe 11.
