ABSTRACT:
A method for the production of corrugated paper comprising the steps of feeding a continuous sheet of paper over a first arcuate roller, making several folds in the paper along lines of radius of the first arcuate roller, passing the paper over a second arcuate roller which has the same center of curvature as the first arcuate roller, and unfolding the paper folds to yield the corrugated paper. The paper preferably turns about 90.degree. in passing over the first and second arcuate rollers, and after being unfolded there is provided additional corrugations by use of crimping rollers or the like.
