ABSTRACT:
A first tension adjustor for adjusting the tension of a liner and a pitch measuring device for measuring the corrugation pitch of a first core board of a single-faced corrugated board are used. A first tension controller operates so that the tension acting on the liner is adjusted on the basis of the corrugation pitch of the first core board of the single-faced corrugated board. Further, a second tension adjustor for adjusting the tension of the single-faced corrugated board and a phase shift measuring device for measuring a phase shift between the corrugations of the first core board of the single-faced corrugated board and the corrugations of a second core board to be laminated to the first core board are used. A second tension controller operates so that the tension acting on the single-faced corrugated board is adjusted on the basis of the phase shift measured by the phase shift measuring device. According to this construction it is possible to prevent a pitch shift and a phase shift of core board corrugations and there can be obtained a corrugated board of high quality.
