The solid forming roller is the feature that distinguishes the Crescent tissue paper machine from other types of paper machines. It does not require vacuuming and relies on the centrifugal force of the forming roller for natural dehydration, with low power consumption.

The forming roller is the only driving roller. The low-concentration slurry is sprayed from the headbox into the space between the felt and the forming wire, and moves along the forming roller. Under the centrifugal force generated by the rapid rotation of the forming roller and the tension of the wire, a large amount of water is dehydrated. The dehydrated water is discharged through the water receiving trough. The water tank is equipped with an angled sheet to prevent the white water from splashing back onto the wire. After dehydration, the paper sheet adheres to the felt and is brought to the drying section with the felt.
