ABSTRACT:
The present invention relates to a conveying method and a conveyor apparatus for the inclined conveyance including the vertical conveyance of materials by superposed two belts and pinching and holding the material to be conveyed between the belts. The present conveying method is characterized by the fact that two belts which are oppositely arranged are superposed. Tensile forces in the direction of the width of the belts is applied to the said superposed belts. Pinching and holding forces for pinching and holding the material to be conveyed between the belts is generated in the superposed belts by the tensile forces, and the material to be conveyed is conveyed by moving the superposed belts in the longitudinal direction.
