METHOD OF DIGITALLY GRADING LEATHER BREAK

摘要

A method and apparatus for grading leather based upon the size and spacing of the breaks in the leather. All or a portion of a hide is fed to a fixture that compresses a local area of the hide into a concave shape. The outer side of the hide is compressed and the inner side of the hide is expanded to cause breaks to be manifested in a local area. The local area of the hide is scanned with a digitizing profilometer that measures the depth of the breaks as the hide is fed through the fixture. The depth data measured by the digitizing profilometer is recorded by a controller. The depth data is then correlated with location data representing the local area scanned to develop a map of the break.
