Abstract
Method for forming a continuous web on a forming fabric includes providing a pressurized chamber, processing the forming fabric through the pressurized chamber, and distributing a pressurized flow of a slurry having a first composition in the pressurized chamber across the width of the forming fabric to form the continuous web.
Claims7
A method of forming a continuous web on a forming fabric, comprising the steps of:
- providing a pressurized chamber, said pressurized chamber being fluidly connected to a source of a pressurized fluid;
- processing said forming fabric through said pressurized chamber;
- distributing a pressurized flow of slurry having a first composition in said pressurized chamber across a width of said forming fabric to form said continuous web;
- and
- ejecting at least a portion of the pressurized fluid against at least one of said forming fabric and said continuous web.
A method of forming a continuous web on a forming fabric having a width, comprising the steps of:
- providing a pressurized chamber, said pressurized chamber being at least partially defined by a plurality of rolls, said pressurized chamber being fluidly connected to a source of a pressurized fluid;
- processing said forming fabric through said pressurized chamber;
- and
- distributing a pressurized flow of slurry having a first composition in said pressurized chamber across said width of said forming fabric to form said continuous web.
A method of forming a continuous web on a forming fabric having a width, comprising the steps of:
- providing a pressurized chamber, said pressurized chamber being at least partially defined by at least one of a plurality of rolls and a chamber housing, said pressurized chamber being fluidly connected to a source of a pressurized fluid, said providing a pressurized chamber comprising the step of providing a roller chamber formed of said plurality of rolls, said roller chamber having at least an inlet nip and an outlet nip;
- processing said forming fabric through said pressurized chamber;
- and
- distributing a pressurized flow of slurry having a first composition in said pressurized chamber across said width of said forming fabric to form the continuous web, said continuous web being de-watered at said outlet nip after formation thereof.
A method of forming a continuous web on a forming fabric having a width, comprising the steps of:
- providing a pressurized chamber, said pressurized chamber being at least partially defined by at least one of a plurality of rolls and a chamber housing, said pressurized chamber being fluidly connected to a source of a pressurized fluid;
- processing said forming fabric through said pressurized chamber;
- distributing a pressurized flow of slurry having a first composition in said pressurized chamber across said width of said forming fabric to form said continuous web;
- providing a second pressurized chamber, said second pressurized chamber being at least partially defined by being at least one of a plurality of second rolls and a second chamber housing;
- and
- processing said forming fabric through said second pressurized chamber.
