  • Automatic guidance device for deformable sheet material
    Patent number: 4776579
    Abstract: An apparatus for feeding a piece of sheet material to a tool utilizes a set of grippers on telescoping arms of a mean trajectory control system for displacing the sheet material in accordance with a predetermined trajectory. Local correction is effected by passing the piece of sheet material between two discs, one of which is rotatable about a horizontal axis but swingable about a vertical axis while the other, on the opposite side of the sheet, is rotatable about a vertical axis coincident with the first vertical axis. A line is marked on the sheet material with a substance stimulated by ultraviolet and emits a wavelength to which photodetectors are responsive to control the local correction device.
