ABSTRACT:
A flexible conveyor belt is provided which can run in a curved shape which elongates along a lower inner wall of a circular pipe, while being completely supported above the lower inner wall by pressurized air introduced into a space between the belt and the lower inner wall. In the case where the flexible conveyor belt is mainly made of rubber, a trough index T (JIS K6322) which is obtained as a ratio of a deflection amount F to a width x of the belt is equal to or greater than 0.35. More strictly, it is preferable to set the thickness y (mm) and the width x (mm) of the belt to satisfy the relationship of y.ltoreq.0.143+6.486.times.10.sup.-3 x+7.904.times.10.sup.-6 x.sup.2. In the case where the flexible conveyor belt is made mainly of a resin, the trough index is equal to or greater than 0.30. The conveyor belts have sufficient flexibility.
