The prepared sample (for standard: 160mm x 12,7mm strips) is put in the upper opening. The strip is heated up to 177ªC between corrugated rotating discs, whereby the flute is formed and ejected at the lower opening. Using the included sample holder the self adhesive tape is applied to complete the sample preparation.

This apparatus flutes the paper samples by means of two fluting rolls. Afterwards, the samples are tested in the crush tester for evaluation of the C.M.T. (Corrugating Medium Test) and C.C.T. (Corrugated Crush Test).
