ることが重要である。This type of conveyor allows all flat-bottomed objects to be rotated about a vertical axis or in any direction by selectively controlling the direction of rotation of the rotating shaft to which the clusters are fixed. The motion of the object is determined by the sum of the frictional forces (magnitude and direction) between the roller and the flat bottom. The direction of action of the frictional force is optimally parallel to the axis of the roller shaft. Frictional forces acting perpendicular to the axis of the roller shaft reduce the efficiency and responsiveness of the material handling conveyor. It is also important that these types of undesirable forces be substantially the same regardless of wet or dry conditions.
