ABSTRACT:
The present invention relates to a sheet tension adjusting method which allows the tension to a single-faced corrugated fiberboard sheet or a liner to be greatly adjusted with a high accuracy to be capable of the adjustment of upward or downward warps of the corrugated fiberboard sheet. In the method according to this invention, when manufacturing a single-faced corrugated fiberboard sheet S.sub.1 in a manner that a liner L.sub.1 is adhered onto a corrugated sheet C.sub.1, the single-faced corrugated fiberboard sheet S.sub.1 is wound around one or more rolls 1 to change a braking force to the roll 1, thereby adjusting the tension to the single-faced fiberboard sheet S.sub.1. Further, this invention is effectively applicable in manufacturing various kinds of corrugated fiberboard sheets.
