Abstract
A method and apparatus for automatically and continuously producing multiple blanks from a coil of sheet material with a minimum of scrap. The apparatus utilizes pinch rolls to advance and retract the sheet material from a coil, while simultaneously a cutter, such as plasma torch, moves transversely to the moving sheet material. Movement of the cutter and sheet material is controlled and coordinated so as to make the desired cuts in the sheet material and produce the blanks of the desired configuration.
Claims11
An apparatus for producing blanks of a desired configuration from a coil of stiff sheet material such as sheet metal or the like, which material is continuously fed to the apparatus, said apparatus comprising a supporting table having an entry end and a discharge end for receiving the sheet material, a material cutting station between the entry end and discharge end, material moving means for controllably advancing and retracting the material from the coil so that the material moves back and forth through the cutting station during the cutting. Operation, cutting means controllably movable back and forth in the cutting station along an axis perpendicular to the direction of movement of the material, and means for coordinating simultaneous movement of the material moving means and the cutting means so as to produce blanks of the desired configuration.
A method for cutting blanks of a desired configuration from a coil of stiff sheet material such as sheet metal or the like which is positioned within a cutting station, said method comprising:
- feeding the sheet material from the coil to the cutting station;
- controllably advancing and retracting the material fed from the coil so that the material is advanced and retracted back and forth through the cutting station;
- controllably moving a cutting means back and forth in the cutting station along an axis perpendicular to the direction of movement of the material simultaneously with movement of the material so as to cut blanks of the desired configuration.
