Abstract
An apparatus and method for detecting defects in the cover sheets used to manufacture diapers is disclosed. A linear sensor is used to detect defects in the cover sheet web before it is combined with the absorbent material to form a diaper. When a defect is detected, the manufactured diaper containing the defective cover sheet is ejected from the line after a delay which is dependent on the speed of the process.
