Abstract
A tubular belt conveyor can transport powdered or granular material without leakage. To roll up a flat belt into a tubular shape, a belt guiding device is provided in the vicinity of a front or a rear end roller. The belt guiding device comprises a base plate and a plurality of guide frames provided on the base plate. In the guide frame, a plurality of guide rollers are arranged like a circle through which the belt to be rolled up passes. The diameter of the circle formed by the guide rollers increases gradually towards the front or the rear end roller to prevent the belt from slacking so that smooth running may be assured.
