PROBLEM TO BE SOLVED: To deal with a sporadic high warming by previously warming by a simple modification of an existing CT type warming apparatus. SOLUTION: A conventional CT type conveyor is modified. A roll 16 having spiral grooves 36 formed thereon is arranged in a body casing 14 and a rubber is introduced while rotatably driving in the casing 14, thereby previously warming the rubber in an initial state. Since heating is conducted by a heater pad from the casing 14 side and also executed with warm water from the roll 14 side, a predetermined preheating can be conducted without considerably deepening the grooves 36 and a load of a motor 44 can be alleviated. |
