Abstract
A tubular belt conveyor in which an endless belt is wound round drive and driven rollers such that an object to be conveyed can be wrapped in the belt and conveyed in the wrapped-in state, comprises supporting frames with a plurality of holding rollers, horizontal rollers, each being adapted to support the bottom of the belt and pivoted on a bracket which is attached to a coupling member of the supporting frame in such a manner that the orientation thereof can be varied, and vertical rollers, each being adapted to support a curved inner peripheral side portion of the belt adjacent to the horizontal roller and pivoted on a bracket in such a manner that the orientation thereof can be varied, whereby the sagging of the belt can be surely prevented, the twisting of the belt can be readily corrected, and the number of holding rollers can be reduced.
