Flat-belt is widely used for conveying the sheet-like medium such as banknotes and cards. In flat-belt conveying, as a trouble leading to operating rate reduction and maintenance cost increase of the device, there is a failure due to belt breaking. As a cause of the belt breaking, scratches caused by handling of the belt, abrasion due to dust contamination from the outside, hydrolysis in a high humidity environment, is known. However, there is a case where the flat-belt is broken rarely even under the conditions that carried out the measures to the above. In this report, focusing on the debris adhering to the surface of the conveying pulley, was subjected to a reproduction test of the flat-belt breaking. The flat-belt breaking mechanism obtained from the results will be described. In addition, an example of a countermeasure against the flat-belt breaking is shown.
