Speed-variable conveyor

摘要

A speed-variable conveyor includes a belt-formed fibrous body (1) deformable in a moving direction and a width direction, a plurality of rollers (2) mounted on both ends in the width direction of the fibrous body, and a pair of guide rails for movably supporting the rollers and differing in spacing according to the moving speed of the fibrous body. The moving speed of the fibrous body is low where the width of the fibrous body is large, and high where the width is small. A support moving body contacting a lower surface of the fibrous body for driving the fibrous body is provided. This reduces a load applied to the fibrous body. <IMAGE>
