    • PROBLEM TO BE SOLVED: To provide a single facer capable of suppressing the vibration of a step roll to prevent cutting of a one side corrugated sheet, as well as lowering running cost and manufacturing cost.
      SOLUTION: In the single facer, a core sheet 7 is corrugated by engagement of a pair of the step rolls 33, 35 engaging with each otherand the corrugated core sheet 7 is bonded with a liner 13 to produce the one side corrugated sheet 15. The single facer comprises a pressure roll mounting member 57 which has an arc-shaped inner peripheral face and is arranged at a prescribed distance from the step roll 33, with its arc-shaped inner peripheral face directed toward the step roll 33 winding the core paper 7 wound between the pair of the step rolls 33, 35, and a plurality of pressure rolls 63 arranged in the pressure roll mounting member 57 in the peripheral direction of the step roll 33 and are pressurized with the step roll 33.

    • PROBLEM TO BE SOLVED: To suppress crack in forming ruled lines on a corrugated cardboard sheet and to suppress lowering of folding accuracy.
      SOLUTION: A corrugated cardboard sheet is held between an upper ruled line roller 43 and a lower ruled line roller 44, with ruled lines formed by a projection 81 formed on the outer periphery of the lower ruled line roller 44. In the upper ruled line roller 43, a projection opposing part 72 is installed oppositely facing the projection 81 of the lower ruled line roller 44. On both sides of the projection opposing part 72, there is installed a supporting part 71 for the projection opposing part. The projection opposing part 72 and the supporting part 71 for the projection opposing part are composed of rubber and urethane, with the hardness of the supporting part 71 for the projection opposing part is higher than that of the projection opposing part 72.
