The pulverized cork is mixed with other papermaking materials and formed into a paper-made substrate. The paper-made substrate is impregnated with a synthetic resin to be a binder and heated and cured. The cork itself has a high friction coefficient ?. Moreover, a powder thereof increases surface area and area in contact with a separator plate of a counter member, thereby improving a friction coefficient of a friction surface of the wet friction member. The friction coefficient of the cork itself and capacities for absorbing and discharging oil are improved by heating the cork. Thus, there is provided a wet friction member that has a higher friction coefficient ?. An increase in the friction coefficient ?, weight reduction by reducing the number of friction members, and high efficiency are achieved when used as a wet friction member.

  • Publication number: 20090151883
    Abstract: There is provided a method of manufacturing coated paper. While a roll coater coating facility and two coating facilities of which coating methods are different from that of the roll coater coating facility are used, the method makes a moisture percentage before a flattening process be stably kept at a moisture percentage in a predetermined range, and improves the stability of quality in the flattening process. Further, the method prevents the contamination of the feed line that is caused by the increase of the length of a feeding line after a coating layer is formed by the roll coater coating facility, and a paper break trouble that is caused by the paper break while the contamination or the moisture percentage of the feed line is high, thereby improving production efficiency. [Means for Solving Problem] The method of manufacturing coated paper consistently performs a papermaking process, a coating process, and a flattening process.

  • Publication number: 20090072014
    Abstract: A system and method for producing waterproof corrugated boards and containers. A technique for waterproofing paper coats the paper with resin, uses non-wicking medium, and creates waterproofed corrugated boards using an adhesive that is compatible relative to the resin used to make the medium non-wicking. The adhesive should also be water resistant or waterproof. Containers made with waterproofed corrugated boards withstand being exposed to wet contents.

  • Patent number: 7422658
    Abstract: The present invention is generally directed to paper products having great softness and strength. The paper products are formed from one or more paper webs that can be made according to various methods. In one embodiment, the paper web is an uncreped through-air dried web. According to the present invention, at least one side of the paper web is treated with a bonding material according to a preselected pattern and creped from a creping surface. Through the process, a two-sided tissue web is formed having a smooth side and a textured side.

  • Patent number: 7422659
    Abstract: A method and an arrangement for treating a web (2) of paper or board is described, in which a functional coating (5) is applied to the web (2) and the web (2) is then calendered. It is wished to obtain a web provided with a functional coating in a cost-effective fashion. This is achieved through the following combination: the functional coating (5) is applied without direct contact, the web (2) is calendered online in conjunction with the application of the coating, calendering takes place in a broad nip (18) in a shoe calender (9), which exhibits a shoe roller (10) with a rotating outer cover (11) and a squeeze roller (14).

  • 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.
