Abstract
A decorrugating sheet transport system includes a drive shaft with three drive rollers mounted for rotation in relation to three idler rollers. The three drive rollers have relieved areas on portions of their circumferences and are positioned on the drive shaft so that upon receiving the lead edge of a corrugated sheet only the two outer rollers drive the sheet initially. This allows the corrugations in the sheet to expand toward the outer rollers. Next, all three rollers drive the sheet for about a 30.degree. arc and then the sheet is driven only by the center roller with the outer two rollers separated to allow the corrugations to dissipate to the edges of the sheet through a small gap between the outer rollers.
