Abstract
A method of circulating a heat transfer medium through a caterpillar and a plate treating apparatus using the caterpillar. A rotary shaft is arranged to transversely project into the caterpillar arranged in an article conveying direction. The caterpillar is provided with a group of strip shaped hot plates disposed closely in parallel to each other, each hot plate having an inlet and outlet of the heat transfer medium. A heat transfer medium passage is formed in each hot plate to communicate the inlet and the outlet thereof. The rotary shaft includes a heat transfer medium supplying portion and a heat transfer medium discharging portion separately formed therein from one end thereof to the other end. The heat transfer medium is sent from the supplying portion of the rotary shaft to the inlet of each hot plate through a corresponding connecting tube, and then the medium is discharged from the outlet of the hot plate to the discharging portion through another connecting tube. The connecting tubes are long enough to reach turning portions of the caterpillar. The rotary shaft and the caterpillar are synchronously controlled in such a manner that the rotary shaft makes a revolution for a turn of the caterpillar.
