  • Patent number: 4343209
    Abstract: A system and method for shearing pieces from bars, characterized by the normal positioning of a bar zone heating element such as an induction heating coil at one or a multiple of piece lengths in front of the bar shear. A bar feed incrementally longitudinally advances a bar one piece length at timed intervals through the heating coil to the bar shear, whereby localized areas or zones of the bar are heated at one piece length intervals. The heat received from the heating coil at each zone soaks into the bar to raise its core temperature as each zone is advanced from the heating coil toward the bar shear. After each incremental advance of the bar, a piece is sheared from the end of the bar at the then presented heated zone.
