A single facer comprising a pair of upper and lower corrugating rolls having a corrugation thereon for corrugating a core sheet fed therebetween. The sheet is then pasted at the tops of their corrugations. A liner is fed in different direction and caused to pass together with the pasted sheet between the lower corrugating roll and a pressure roll to be sticked to each other to thereby form a single-sided corrugated sheet. The upper and lower corrugating rolls are supported by separate rotatable frames, and engageable with each other to form a corrugation forming unit. A plurality of corrugation rolls having a different corrugation shape thereon are provided on each of the rotatable frames.
