Abstract: The invention relates to apparatus for measuring the area and thickness of irregular articles such as animal pelts or skins. The apparatus broadly comprises a non-reflective conveyor support for articles to be measured, a series of photo-electric cells extending across said conveyor support, light means for illuminating an article on the support from above and by reflection from the article energizing such cells as register with the article, electronic means for correlating the corresponding increments of movements of the article and the sum of increments between photo-electric cells energized and computing therefrom the area of the article; at least one electrical to mechanical transducer positioned so as to bear against the article and be adjusted by varying thicknesses thereof, and measurement indicating means connected to said transducer responsive to the electrical output therefrom and adapted to indicate and/or record the thicknesses detected by the transducer.
