Abstract (en)
This invention relates to a corrugating unit for manufacturing corrugated board. According to the invention, the firm contact of the corrugated paper (4), or corrugated medium, against the shaped surface of the central corrugating cylinder (2) is caused by an air cushion acting on the side of the corrugated paper opposite to that being engaged with the central corrugating cylinder (2), and which is formed and fed in a zone which is divided into controlled decompression sections.
