Inline lamination and coating of a cellulose based substrate

A coater comprising:

• a first coating station;
• a nip assembly;
• a second coating station;
• a third coating station;
• a first unwind stand;
• and
• a second unwind stand, wherein
• in a first configuration, the coater is configured such that a first cellulose based substrate travels from the first unwind stand to the first coating station, from the first coating station to the second coating station, and from the second coating station to the first reel section, wherein a first coating is applied to a first side of the first cellulose based substrate at the first coating station, and a second coating is applied to a second side of the first cellulose based substrate at the second coating station, and
• in a second configuration, the coater is configured such that the first cellulose based substrate travels from the first unwind stand to the nip assembly, a second cellulose based substrate travels from the second unwind stand to either the first coating station or the second coating station and then to the nip assembly, wherein an adhesive is applied to a side of the second cellulose based substrate at either the first coating station or the second coating station, the first cellulose based substrate contacts the adhesive side of the second cellulose based substrate at the nip assembly to form a laminate, the laminate travels to the third coating station, wherein a coating is applied to the first cellulose based substrate side of the laminate to form a coated laminate.

A method for laminating substrates, the method comprising:

• providing a coater comprising:
• a first coating station;
• a nip assembly;
• a second coating station;
• a third coating station;
• a first unwind stand;
• and
• a second unwind stand, wherein
• unwinding a first cellulose based substrate from the first unwind stand;
• directing the first cellulose based substrate to the nip assembly;
• unwinding an second cellulose based substrate from the second unwind stand;
• directing the second cellulose based substrate to either the first coating station or the second coating station;
• directing the second cellulose based substrate to the nip assembly;
• applying an adhesive to a side of the second cellulose based substrate at either the first coating station or the second coating station;
• contacting the adhesive side of the second cellulose based substrate with the first cellulose based substrate at the nip assembly to form a laminate comprising a first cellulose based substrate side and a second cellulose based substrate side;
• directing the laminate to the third coating station;
• applying a coating to the first cellulose based substrate side of the laminate to form a coated laminate.
