PURPOSE:To enable a correction by detecting the torsion of a belt by providing a sensing roller and a rectification roller on a supporting frame of a roller holding a belt in cylindrical shape CONSTITUTION:A belt 1 which contains goods to be carried and runs in a cylindrically formed condition is supported by plural shape keeping rollers 6 provided on a supporting frame 4 so as to form a circular shape. A torsion sensing roller 24 supported by arms 19 and 20 is provided on the supporting frame 4 so that the torsion sensing roller 24 is oscillated according to the torsion of the belt 1, with which a microswitch 25 is actuated. Then a rectification roller 15 is to rectify the torsion of the blet through its oscillation actuated by a solenoid 17, and occurring of a scattering accident of the goods to be carried resulting from the torsion to be occurred during running of a long conveyor can be prevented. |
