PROBLEM TO BE SOLVED: To provide a novel coating station which can be designed so that it may be simpler, lighter in weight, and more general-purpose than the conventional one, is higher in the degree of freedom for the arrangement of a forming machine. SOLUTION: The coating station is used to coat a web (11) with a coating material. The station (10) includes a load-bearing and cross-directional frame (12) which extends substantially across the entire width of the web (11). The station (10) is supported by a frame (12) and includes applicator elements (13) that imparts the coating material to the surface of the web passing through the station. The frame (12) is composed of at least one cross component (14, 14', or 14") formed out of sheet metal into a box-type structure. The cross component extends substantially over the entire width of the web (11). The edge of the cross components (14, 14', or 14") are attached to attached end components (15).

PROBLEM TO BE SOLVED: To provide a drying method for a fiber web solving the problem of a curling caused by the sharp water content gradient in the fiber web without enlarging the equipment and without impairing drying capacity. SOLUTION: The method for drying the fiber web such as a paper web or paperboard web is provided. In this method, because the fiber web (W) is dried in such a manner that substantially one side thereof is dried in a belt drying unit (RC) at least one drying step, a water content gradient is caused in the fiber web (W). This method comprises the following practice. The fiber web (W) is dried by an impingement drying unit (RP) substantially just before and/or substantially just after drying it in the belt drying unit (RC), thereby leveling the above-mentioned water content gradient. In this impingement drying unit (RP), the fiber web(W) is dried from the side opposite to the side to be dried or dried by the belt drying unit (RC). COPYRIGHT: (C)2004,JPO

PROBLEM TO BE SOLVED: To easily perform leading of a web threading tail in improved reliability compared with conventional methods. SOLUTION: The invention relates to a method in leading a web threading tail particularily in a paper machine. A device to be attached to a frame structure of the paper machine is used in the method. The device is moved close to the fabric transporting the web threading tail to detach the web threading tail from the surface of the fabric. The web threading tail is transferred relative to the direction of travel to the following web threading device and, thereafter, the device is moved away from the vicinity of the web threading tail. The transfer of the web threading tail is mechanically performed by the pushing motion in the cross direction of the paper machine. The invention also relates to a corresponding device.

Abstract:
PROBLEM TO BE SOLVED: To provide the arrangement of a high pressure water device capable of being assembled simpler and at a lower cost than usual one in a paper making machine and a method for arranging the high pressure water device in the paper making machine. SOLUTION: This arrangement of the high pressure water device is as follows. The paper making machine includes >=2 sequential sub-totalities for paper making such as a wire unit (10), a pressing unit (11), a drying unit (12), a finishing unit (13) and the like. The arrangement of the water device includes a pump device (17) for producing high pressure water, water operation devices installed to various points (14-16) of consumption arranged within the sub- totalities and connections (18) for guiding high pressure water from the pump device (17) to the operation devices. The pump device (17) includes at least one pump unit (19) from which the connections (18) are arranged to the various points (14-16) of consumption belonging to the >=2 sequential sub-totalities (10-13).

PROBLEM TO BE SOLVED: To provide a roll end forming method for easily forming the roll end and effectively reduce heat load of a bearing. SOLUTION: The present invention relates to the roll end forming method for the roll of the paper or board machine, or in a finishing machine, particularly, the heating roll. A roll end 30 comprises a main body constituted of an end flange 31, a shaft journal 32, and a duct system 10. Since the duct system is installed in the roll end 30, heating medium circulates to enter into and go out of a hole of a roll shell from the outside of the roll through the shaft journal 32 and roll end 30, inside the finished roll end. In the method of the present invention, the roll end 30 is formed in a mold 20 by powder metallurgy processing, and the duct system for heating medium 10 is formed by the powder metallurgy process relative to the manufacture of the roll end. For the manufacture of the roll end, especially, a hot isostatic pressing method is used.
Abstract:
PROBLEM TO BE SOLVED: To provide a composite braid having simple structure and easiness to use. SOLUTION: This composite braid is characterized in that a holding member is composed of a profiling 16 extended as a united extended part in the transverse direction of a braid member 13 throughout the overall length of the braid and united with the braid member 13 in the braid 10 having the composite structure composed of substantially the plate-shaped braid member 13 having a composite structure and the holding member arranged at the rear side 14 thereof and formed by holding the holding member in the throat part 15 of a particular braid holder 11 so as to be installed to the braid holder 11.
Abstract:
PROBLEM TO BE SOLVED: To provide a novel roll shell to make the technical structure of a roll less complex and to improve the heat transfer properties of the roll to reduce the weaknesses associated with the conventional art. SOLUTION: This publication deals with a heatable and/or coolable roll, i.e. a thermo roll, of a fibrous web machine for the treatment of a fibrous web, for example for pressing and/or calendering the fibrous web in contact, i.e. in a nip, between the thermo roll and a backing member which is in contact with the thermo roll or for drying or cooling the fibrous web on the shell surface of the thermo roll.
