Abstract
A wrapping state of a wrapped roll of a continuous sheet material which is rolled and wrapped with a sheet-like wrapping material is checked by taking an image of the wrapped roll placed in a predetermined position, and processing information on the image of the wrapped roll with respect to the density of the image, thereby detecting data on wrapping state of the wrapped roll, and determining whether the wrapping state of the wrapped roll is satisfactory on the basis of the detected data.
