PURPOSE: To enable a belt conveyor to be simply adapted for a linear and a curved shape, by a method wherein inclination parts are formed to a final end part and a starting end part, where a plurality of belt conveyers are adjoined to each other, the inclination parts are superposed with each other so that the belt conveyor can be arranged in series and a coupling angle with each other is regulatable.

CONSTITUTION: Preceding and subsequent belt conveyers 11 and 16 are connected in a manner that inclination surfaces 11a and 16a are superposed with each other. The two belt conveyers 11 and 16 are intercoupled by means of a turn- buckle-form coupling tool, not shown, and a relative angle between the frames of the two belt conveyers 11 and 16 is regulatable. This constitution enables formation of a conveyance passage, properly bent, through regulation of the frame angles of the belt conveyers 11 and 16. Thus, the length of the belt conveyor can be increased, the number of conveyance trucks can be increased, and efficiency is improved.
