  • Patent number: 11731304
    Abstract: In order to be able to slice product pieces, whose cross-section varies along their length, into weight-accurate slices, after pressing to a uniform product caliber it is possible to measure these realistically in terms of cross-sectional area and length and not in a pumped up state of the machine. On the one hand, this is promoted by the fact that even before pressing, a cross-press stamp is set to a forming tube cross-section oriented to the unpressed product piece. On the other hand, this is promoted by the fact that after pressing, by lowering pressing force to a substantially lower holding force, it is possible to deform back the deformed, pumped up machine parts before measuring the product caliber.

  • Patent number: 9347182
    Abstract: An improved processes for making fluff pulp sheets mechanically eliminates many of the unwanted fiber-to-fiber bonding (fiber bundles) which may be contained in the sheet to produce consistent and uniform quality fluff pulp. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break a majority of fiber bundles contained in the web. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. A shoe press can be used to dewater the web after it is subjected to the pulsating shear forces. The web can be dried utilizing conventional drying equipment, such as cylindrical driers.

( ? / 2 ) where t is tension applied to the web; G is roll retaining force with which the roll surface frictionally retains the web; V is thermal expansion force generated by thermal expansion of the web retained on the roll surface; ?A1 is pressing force caused by the tension to the web and applied to the roll surface by the web; ? is a wrap angle at which the web contacts the roll surface. Thus, distortion of the web can be prevented even with a great difference in the temperature from the thermal roll.

  • Patent number: 7169259
    Abstract: A dry end of a tissue machine is made shorter by close-coupling a reel-up to the drying section and supporting the web from the drying section to the reel-up by a foil or a belt such that web stability is maintained, thus allowing high-speed operation. The foil's downstream edge can form a nip with the paper roll and nip load can be controlled by controlling pivotal movement of the foil. The reel-up can include a calendering belt for calendering the web as it passes through a nip between the belt and a reel drum supported on the belt, and a rotatable reel spool on which a paper roll is wound in nipping engagement with the reel drum. Alternatively, the reel drum can be eliminated and the paper roll can be supported on the belt. A composite shaftless core for winding is also disclosed.

    Abstract: A shoe roll of a shoe press for use in a papermaking machine, the shoe roll including a blanket, or endless belt, which houses a shoe assembly that, in cooperation with an external backing roll, forms an extended nip proper. The shoe press includes an oil circulation piping system for removing the oil from the interior of the shoe roll and transferring the oil to an oil trap during the running of the machine, whereby the piping system also includes a suction fan connected thereto. The device is implemented by way of connecting an oil siphon to the oil circulation piping system, the oil siphon adapted to move towards and away from the blanket in the interior of the shoe roll so that, when the roll is stopped, the siphon removes the excess oil from the interior of the blanket by a pressure differential generated by of the suction fan.

  • Patent number: 7074303
    Abstract: A shoe press for a papermaking machine having clamping means mounted onto the head from the end thereof remote from the blanket. In one embodiment, the head itself is provided with a wedge surface in engagement with respective inclined surfaces of wedge segments and the blanket extends between these wedge segments and opposing surfaces provided on the clamping means. Axial displacement of the clamping means relative to the head, e.g. by tightening or releasing of bolts, then causes the blanket to be clamped between the wedge segments and the clamping means or to be released and removable therefrom. In another embodiment, it is the clamping means which is provided with wedge surfaces in engagement with respective inclined surfaces of wedge segments, and the blanket then extends between the wedge segments, and an opposing flat surface on the head. However, in other respects axial displacement of the clamping means brings about clamping or release of the blanket edge in the same manner.
