Abstract

PURPOSE:To make it possible to put pressure upon the entire pressurized part of a running belt guide board ina movable side frame evenly, and to cool the guide board, by setting a pressurized refrigerant tank on the guide board in the movable side frame, which is set on the upper part of a fixed side rack. CONSTITUTION:A belt bridle has a fixed side rack 1 and a movable side frame 2. On the rack 1 and the frame 2, running belts 3, 4 are twined round two pairs of drums 5, 6, respectively, and guide boards 7, 8 are set between the drums 5, 6, respectively. In this mechanism, on the guide board 8 in the movable side frame 2, a pressurized refrigerant tank 12 made of an elastic vessel is set, and in this tank 12, a pressure refrigerant supplying hole 13 and a pressure refrigerant exhausting hole 14 are formed. Then, this tank 12 is expanded and the pressure is put upon the entire pressurized surface of the guide board 8 evenly, by supplying the pressure refrigerant in the pressurized refrigerant tank 12, and the rise of the temperature, caused by the frictional heat of the guide board 8 and the running belt 4, is prevented, by cooling the guide board 8 by the flow of the pressure refrigerant.
