DANDY ROLL

A dandy roll is situated near the end of the wire section. It is covered with a woven wire and is in contact with the upper surface of the forming web.

As the wet web of paper passes under the watermarking dandy roll, the design is impressed into the paper which results in a permanent watermark on the sheet.
