Abstract
Method and equipment for the manufacture of corrugated paper products includes separate heaters for preparing liner and medium components. Data regarding these components is collected and an optimum conditioning for the components is determined.
Claims8
Apparatus for preparing a paper web having first and second opposed major surfaces and containing moisture, for corrugation, comprising:
- heating means with a curved outer heated surface;
- a wrap arm movable across the outer heated surface of the heater, for wrapping the paper web across the heating means;
- means for moving the wrap arm between first and second positions so as to bring greater and lesser portions of the paper web in contact with the heating means;
- sensor means for sensing, for the different positions of the wrap arm, the moisture carried of the paper;
- means for determining a low moisture wrap arm position at which a rate of increase of web moisture increases;
- means for determining a high moisture wrap arm position at which a rate of increase of web moisture is negligible;
- means for determining an offset comprising one-half of the difference between the low moisture wrap arm position and the high moisture wrap arm position;
- means for determining a desired operating position of the wrap arm by adjusting the high moisture wrap arm position toward the low moisture wrap arm position by an amount corresponding to the offset;
- and
- means for moving the wrap arm to the desired operating position.
