ABSTRACT:
Herein disclosed is a corrugating machine for forming a single-face corrugated paper web from a pair of webs passing therethrough. The corrugating machine comprises a first corrugating roll and a second corrugating roll parallel to and in meshing engagement with the first corrugating roll, the second corrugating roll carries a web of corrugated paperboard material around a portion of the outer periphery thereof. A floating guide continuously urges the corrugated web against the outer periphery of the second corrugating roll and is automatically self-adjusting for compensating for irregularities in the second corrugating roll and the corrugated web. An adhesive roll is in contact with the corrugated web extending around the second corrugating roll for applying adhesive to the tips of flutes on the corrugated web. A pressure roll carrying a facing web on the outer periphery thereof is in contact with the adhesive covered tips of the corrugated web forming the single-face corrugated web.
