An apparatus for producing a single face corrugated web is disclosed. The apparatus includes a first corrugating roll (14), a second corrugating roll (16), a first smoothing roll (34) provided in a feeding path of a liner web (32) and driven so as to have a rotation speed (V1) which is equal to or less than a feeding speed (V0) of the liner web (32), a second smoothing roll (48) provided in a feeding path of the single face corrugated web (S) and driven so as to have a rotation speed (V2) which is greater than the feeding speed (V0) of the liner web (32), a third smoothing roll (46) provided in the feeding path of the liner web (32) between the first smoothing roll (34) and the second corrugating roll (16) and driven so as to have a rotation speed (V3) which is equal to or less than the feeding speed (V0) of the liner web (32). The apparatus further includes means (52) for varying the rotation speed difference (V2 - V1) between the first smoothing roll (34) and the second smoothing roll (48) based on a change in any one of the conditions such as paper quality, paper width, production speed, etc., of the medium web (18) or the liner web (32), or a change in combinations of the conditions. <IMAGE> |
