Identification carrier for serial parts such as vehicle bodies, includes two-dimensional matrix with numerical figures defined by two holes in column of five rows in sheet metal

摘要

The ID carrier includes figures from 0 to 9 in the form of holes in sheet metal (2). Circular holes (6) are punched out of the metal in a conventional hole code. The hole code is provided two-dimensionally in a matrix (9) of rows and columns. Each figure is defined by two corresponding holes (6,6) in a column extending for five rows (7).
