A permanent invisible magnetic marking and positioning system of cylindrical metal steel rods. To accurately locate the physical midpoint of the rod-to-be-cut, a novel head centering and positioning mechanism automatically sets the midpoint distance for each setup as the length of the finished rod stock is changed. The steel rod that is used to manufacture the U-bolts is inserted lengthwise into a cutoff saw station or machine until it comes in contact with a stop that is set to the desired predetermined length. An automatic centering device positions the magnetizing heads located at the longitudinal center, on each side, of the steel rod. A high-energy rectangular pulse imparts a permanent invisible magnetic mark at the longitudinal center of the steel rod before being formed into a U-bolt. The rod is then suitably cut to the desired predetermined length, and each of the opposite ends threaded with the desired thread size. The unbent threaded rod is positioned in the hydraulic or powered bending machine, so that the longitudinal center of the rod is aligned to the center of the bending mandrel, using a peak magnetic detector that is used to locate the magnetic center of the rod.

A permanent invisible magnetic marking and positioning system of unfinished steel rods, spring steel bars, workpieces, and the like. A midpoint or center of the rod, bar or workpiece is automatically located and a high-energy pulse is applied for an embedded magnetic marker in the workpiece. Meanwhile, the magnetizing heads can also be repositioned to various points on a workpiece for imparting manufacturing and product identification data. In the case of leaf springs, the center of a spring steel bar is located a magnetic marker is embedded there. A high-energy rectangular pulse imparts a permanent invisible magnetic marks and data. The embedded indicators having peak magnetic strength allow manual or automatic positioning for perfect alignment in bending, tapping and other forming processes.

A permanent invisible magnetic marking and positioning system of unfinished ferrous rods, bars, workpieces, and the like. A midpoint, center or other point of the workpiece is automatically located and a high-energy pulse is applied for installing an embedded magnetic marker. The magnetizing heads can also be repositioned to various points on a workpiece for imparting digital manufacturing and product identification in a data strobe pulse, that is analogous to a picket fence, where each picket provides a weighted binary representation in a data array comprised of data cells.
