Abstract
A method of forming a fibrous web on a papermaking machine including the steps of depositing a dilute fiber slurry out of a headbox to a forming area comprising a forming surface made up of a structured fabric, wherein the structured fabric is supported by a breast roll and a forming roll, and the forming area is devoid of any additional fabrics or belts other than the structured fabric, draining the dilute fiber slurry through the structured fabric, and drying the fiber slurry.
Claims33
A papermaking machine comprising:
- a forming section configured to form a nascent fibrous web, the forming section comprising a nip formed between two rolls comprising a forming roll and a single fabric that is a structured fabric that wraps around the two rolls, the structured fabric configured to receive a fiber slurry deposited from a headbox so as to form the nascent web, the forming section being devoid of any fabrics or belts other than the structured fabric;
- a dewatering or press section into which the nascent web travels on the structured fabric after separation of the structured fabric from the forming roll;
- and a dry end section after the dewatering or press section through which the nascent web travels after being transferred from the structured fabric.
