ABSTRACT:
To provide a corrugating roll for a single facer which avoids generation of press marks or fracture of paper without a loss of paper by suppressing a contact pressure between a corrugating medium and a liner paper, and which may manufacture the corrugated paper in a low cost with easiness of machining work, in a corrugating roll for a single facer, in which a pair of corrugating rolls engage with each other through a tooth form in parallel to roll axes on circumferential surface portions of the rolls, a profile of a tooth tip portion is composed, in combination, of a plurality of arcs that are symmetrical with respect to a tooth apex portion. The profile of the tooth tip portion includes the tooth apex portion and is constituted in combination by a first arc having substantially the same radius of curvature as that of an outer circle of the corrugating roll. The profile of the tooth tip portion is constituted in combination by a second arc that inscribes with the first arc at a terminal portion of the first arc. The profile of the tooth tip portion is constituted in combination by a third arc that circumscribes with the second arc at a terminal portion of the second arc.
