    Abstract: A method of laminating a surface of a flexible material to a surface of a rigid, curved material. The method includes pressing an area of the surface of the flexible material into the surface of the rigid, curved material with a holder to create a contact area while the flexible material is conformed to the holder, which has a curvature greater than a curvature of the rigid, curved material surface; and changing the contact area between the surface of the flexible material and the surface of the rigid, curved material while maintaining pressure on the contact area until the surface of the flexible material and the surface of the rigid curved material are laminated.

  • Powder press
    Patent number: 8814549
    Abstract: A powder press has an upper yoke, a lower yoke, and a tension element that is in effect between the upper yoke and the lower yoke, as well as a die accommodation plate that is guided along the tension elements. The plate can be displaced parallel to the tension element, via a punch that supports itself on the upper yoke or the lower yoke, or to which pressure can be applied. The punch accommodates a die plate provided on an adapter and includes at least a cylinder and/or a piston disposed in the cylinder, to which hydraulic pressure can be applied in the cylinder. The powder press has a particularly compact construction if the cylinder and/or the piston surrounds a passage opening through the die accommodation plate or through the upper or lower yoke and/or a tension element.

  • Method and arrangement for adding treatment liquors to cellulose raw material in a continuous process using down flow vessels
    Patent number: 8801898
    Abstract: The method and arrangement is for adding treatment liquor to comminuted cellulose material, preferably wood chips, during the manufacture of chemical pulp in a continuous process. The process uses a down-flow vessel where chips are descending down the vessel in a plug-flow and where treated chips are continuously fed out at the bottom of the vessel. By arranging more than two parallel pipes offset from the center of the vessel a better distribution of treatment liquor is obtained. Any disturbance of the chip plug flow descending down the vessel is reduced to a minimum.
