PURPOSE: To simplify apparatus and to prevent meander of a belt by arranging supporting shaft and a rotating shaft to a roll and also tension giving device to frames and fitting the fame at right and left sides into grooving holes with pins to difference directions.
CONSTITUTION: The supporting shaft 1 and the rotating shaft 2 are arranged to a housing, etc., in a casting machine and the tension roll 7 is supported with the frames 5, 5'. The tension giving devices 6, 6' of hydraulic piston, etc., are arranged to the frames 5, 5' and right and left end parts 8, 8' of the roll 7 are shifted. Then, the grooving holes 10, 10' are arranged in the frames 5, 5', and the pins 4, 4' of the brackets 3, 3' are inserted, to fit the brackets 3, 3' to the different directions. By working the devices 6, 6'. The tension is given to the belt 9, and by rotating the rotating shaft 2, the roll ends 8, 8' is inclined to prevent the meander of the belt 9. By this method, the apparatus is simplified and the development of meander of the belt 9 is prevented.
