  • Patent number: 11834791
    Abstract: A method for manufacturing a paper barrier base material includes a step of applying a water vapor barrier layer coating liquid that contains at least a water vapor barrier resin and a pigment onto a paper base material by a curtain coating method to form a water vapor barrier layer, and a step of applying a gas barrier layer coating liquid that contains at least one polymer selected from water-soluble polymers and water-dispersible polymers onto the water vapor barrier layer by a curtain coating method without a drying step interposed between the two steps to form a gas barrier layer. The gas barrier layer coating liquid has a B-type viscosity equal to or higher than a B-type viscosity of the water vapor barrier layer coating liquid. The method is intended to suppress the occurrence of coating unevenness in wet-on-wet coating by a curtain coating method.

  • Patent number: 7540941
    Abstract: An applicator device (1) applies surface size to at least one side of a web (W). A pressure effect is applied to the web (W) by subjecting the web (W) to an underpressure and/or to an overpressure such that surface size is forced to penetrate into the pores of the web. Most advantageously, an underpressure is created that sucks applied surface size from the surface of the web (W) into the pores in the inner layers. Surface size is applied to a web first side (W1) and a vacuum effect is applied to the web's opposite side (W2) to cause air to flow through the web (W) such that surface size moves from the first side (W1) in the direction of the second side (W2) into the web (W). Correspondingly, both sides of the web (W) can be treated in successive stages.

  • Patent number: 7390557
    Abstract: A method for manufacturing a web of paper and paperboard, in which method a spray-coating technique is used for applying a web treatment substance to at least one surface of a moving web. The qualities of the web treatment substance are selected such that at least the droplet size and viscosity of the web treatment substance are controlled such as to make the thickness of the applied web treatment substance essentially equal in at least two randomly selected sample areas. According to the invention, the applied coating conforms with the surface contour of the base sheet. A paper manufactured using the method.

  • Patent number: RE40857
    Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes. The base sheet of the coated paper is preferably formed square on a paper machine wet end and has on the order of 40-50% less filler than conventional sheet paper made for electrophotographic processes. After being formed and dried, the base sheet is provided with a top coat weight that is approximately 60% less than the typical coat weight used for conventional paper. The coating is formulated to have sufficient viscosity to stay more on the surface of the base sheet. The coated sheet is calendered to a medium gloss on the order of a 75° TAPPI gloss of about 45, both to preserve a degree of surface roughness to enhance runnability of the paper through an electrophotographic copier and to provide a pleasant and easily readable surface.
