A coater configured to manufacture a laminated coated product. The coater includes a first coating station configured to apply an adhesive to a side of a first cellulose based substrate, a first nip assembly configured to press the adhesive coated side of the first cellulose based substrate to a second cellulose based substrate to form a laminate, a first dryer section configured to dry the adhesive in the laminate, a second coating station configured to apply a coating to the second cellulose based substrate side of the laminate, a second dryer section configured to dry the coating on the laminate, and a reel section configured to wind a reel of the laminate.

A material deposition system and method is disclosed for depositing material onto raised features on a surface of a substrate. The material deposition system and method are a contact deposition or printing system and method, which employs biased rollerball to deposit the material as it travels along the substrate and over the raised features.

Provided are a method and an apparatus for producing a film with a coating solution including a material whose performance is deteriorated by oxygen functional film, without performance deterioration. The apparatus for producing a functional film includes a coating device which has a backup roller and a die coater and applies a coating solution having a dissolved oxygen concentration of 1000 ppm or less and including 10000 ppm or less of an organic solvent to a flexible support transported in a state where the support is wound around the backup roller to form a coated film, a lamination device which laminates a coated surface of the coated film and the film on the backup roller, and an inert gas atmosphere forming device which forms an inert gas atmosphere in a space including the coated surface from a coating start position to a lamination start position on the backup roller.

A flow-on roller coating system includes a roller frame, a roller rotatably supported by the frame, and a depositor operatively coupled to the frame. The depositor is configured to receive a supply of coating and deposit the coating onto an exterior surface of the roller. The depositor may include an engagement portion having a contact region in direct contact against the exterior surface of the roller, and one or more outlet openings in the engagement portion are located within a perimeter of the contact region. The outlets are configured to discharge coating onto the exterior surface of the roller, which is penetrated into the roller. The depositor may include an intake chamber and a discharge chamber which are separated by a one-way valve. The one-way valve may help to meter the amount of coating discharged from the depositor body, which can help to reduce excess coating flow to reduce drippage.

The present invention discloses a laminating machine. A glue outlet roller set and a feeding driving device are arranged in a machine body; the glue outlet roller set is located on the side, close to an outlet, of a laminating roller set; the linear speed of the roller face of the glue outlet roller set is larger than that of the roller face of the laminating roller set; the static friction force between the glue outlet roller set and a laminating object is smaller than that between the laminating roller set and the laminating object; and when the laminating object enters the glue outlet roller set through the laminating roller set, the laminating roller set and the laminating object are in static friction fit, meanwhile, the glue outlet roller set and the laminating object are in sliding friction fit, the plastic-packaged laminating object is tensioned and subjected to glue outlet, a glue film is prevented from being wrinkled and corrugated, and the laminating quality is improved.

According to an embodiment, provided are a coating device, a meniscus head, and a coating method capable of obtaining a uniform coating film with a large area. A coating device according to an embodiment forms a coating film by a meniscus method, the coating device comprising: a member that conveys a base material; a coating bar; a slot die that supplies a coating liquid to a surface of the coating bar; and a member that supplies the coating liquid to the slot die, in which each of the members is disposed such that the coating liquid supplied from the slot die is supplied to a space between the coating bar and the base material via the surface of the coating bar to form a meniscus.

A roll for a hot-dip metal coating bath has a substantially cylindrical shape. At least an outer peripheral surface of the roll is formed of a ceramic material. A relatively coarse groove is formed on the outer peripheral surface of the roll in a direction crossing the rotation axis. A plurality of relatively fine grooves is formed in the bottom surface of the coarse groove along the longitudinal direction of the coarse groove. In place of the fine grooves extending in the longitudinal direction of the coarse groove, a plurality of rows of fine grooves may be formed along the crosswise direction of the coarse groove.
