Paper-making of Dark Roast Paper Filter
Wet Creping Method
The roller rotates faster than that by the Dryer drum. Thanks to the rotating speed difference (the difference is bigger than that when the light roast paper is made), the wet paper loose at the doctor blade. The two-side crepe is made by the speed difference but the paper with two-side crepe is dried on the drum, so the two-side crepe becomes lower than that made by Air Through dry.
