3 Overview
Leather area measuring machine is mainly used to measure the sheepskin, pigskin and cowhide leather and other areas can also be measured therewith
Similar soft, opaque sheet material area.
Leather works area measuring machine using a photoelectric conversion area to be measured is converted to electrical signals, counting circuit
Exhibit area value, the measurement results can be printer output, stamp mechanism can also be output.
Leather area measuring machine consists of measuring station, electrical control box and the print mechanism and other components. Press machine knot
Structure is divided into horizontal, vertical, horizontal legislation three types, the shape shown in Figure 1, Figure 2, Figure 3.
