Abstract
A method and apparatus are used to form a corrugated web having a cross sectional shape with at least one characteristic that varies substantially continuously along the substantially the entire length of the web. The apparatus includes multiple sets of dies which progressively form corrugations in a moving sheet. At least one characteristic of the web's cross sectional shape is varied along the entire length of the web by displacing the dies as the sheet moves through the die sets.
