| 摘要 |
A corrugated paperboard manufacturing apparatus includes preheaters, a double-facer, a cutter, and a board edge profile sensor downstream from the cutter for sensing a profile of a cut edge of a cut panel. A processor controls the double-facer and the preheaters responsive to the board edge profile sensor to thereby reduce warp in the cut panels. The board edge profile sensor is preferably an optical sensor, and, more preferably, may be a camera. Accordingly, near real time feedback may be used to adjust the upstream process to produce high quality paperboard. The board profile sensor also preferably further includes an associated scanner for optically or mechanically scanning the cut edge of the cut panel. A conveyor preferably carries the cut panels away from the cutter and toward a stacker. The board edge profile sensor may be positioned adjacent the conveyor or the stacker. Method aspects of the invention are also disclosed. |
