<p><P>PROBLEM TO BE SOLVED: To provide a conveyor belt capable of preventing the transfer of a compounding material between upper and lower cover rubber layers when it is wound in a roll shape without complicating packing and unpacking operations. <P>SOLUTION: Protrusions 8 having a protrusion height from a surface of 1.0 mm or less are integrally provided to at least one of the surfaces of the upper and lower cover rubber layers 2 and 3. When the conveyor belt 1A is in a flat state and when the upper cover layer 2 is overlaid on the lower rubber layer 3, a ratio of an area where the surfaces are brought into contact with each other relative to the total overlapping area is 30% or less. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
