Abstract
An in-line paperboard moisturizing and pressware forming system broadly comprising a paperboard moisturizing system and a pressware forming system in-line with the paperboard moisturizing system. The paperboard moisturizing system broadly comprises a supply roll carrier, a payout roller, a water spreader, and a control system. The supply roll carrier dispenses paperboard material. The payout roller meters the paperboard material from the supply roll carrier. The water spreader evenly moisturizes the paperboard material. The control system controls a feed rate and moisture level so that the paperboard material has a desired moisture content as the paperboard moisturizing system delivers the moisturized paperboard material to the pressware forming system.
Claims20
An in-line paperboard moisturizing and pressware forming system comprising:
- a paperboard moisturizing system comprising:
- a supply roll carrier configured to dispense paperboard material;
- a water spreader configured to deliver water evenly to the paperboard material to moisturize the paperboard material;
- a water supply configured to meter the water to the water spreader;
- and
- a control system comprising a controller configured to instruct the supply roll carrier to advance the paperboard material according to a feed rate;
- and
- a pressware forming system configured to directly receive the moisturized paperboard material, the control system being further configured to instruct the water supply to meter water to the paperboard material via the water spreader according to a desired moisture level so that the paperboard material has a desired moisture content as the paperboard moisturizing system delivers the moisturized paperboard material to the pressware forming system.
An in-line paperboard moisturizing and pressware forming system comprising:
- a paperboard moisturizing system comprising:
- a supply roll carrier configured to dispense paperboard material;
- a water spreader configured to deliver water evenly to the paperboard material to moisturize the paperboard material;
- a water supply configured to meter the water to the water spreader;
- and
- a first control system comprising a controller configured to:
- instruct the supply roll carrier to advance the paperboard material according to a first feed rate;
- and
- instruct the water supply to meter water to the paperboard material via the water spreader according to a desired moisture level so that the paperboard material has a desired moisture content;
- and
- a pressware forming system in-line with the paperboard moisturizing system, the pressware forming system comprising:
- a scoring station configured to receive the paperboard material from the paperboard moisturizing system, the scoring station including a scoring tool configured to be pressed against the paperboard material thereby scoring the paperboard material;
- and
- a forming station configured to receive the scored paperboard material from the scoring station, the forming station comprising a forming tool including a mold configured to shape the paperboard material.
A method of moisturizing paperboard material, the method comprising steps of:
- dispensing paperboard material from a supply roll carrier;
- metering water to a water spreader via a pump of a water supply;
- delivering the water from the water spreader evenly to the paperboard material so the paperboard material is evenly moisturized;
- advancing the moisturized paperboard material to a pressware forming system;
- instructing, via a controller, a motor of the supply roll carrier to advance the paperboard material according to a feed rate;
- and
- instructing, via the controller, the pump to meter the water according to a desired moisture level so that the paperboard material has a desired moisture content as the paperboard material advances to the pressware forming system.
