  • Patent number: 4116763
    Abstract: The separator of the machine is constructed to retain the paper web on the inner (upper) wire upon separation of the two wires. To this end, the separator positions the roll for the outer (lower) wire downstream of the point of separation of the two wires. A suction box can be used in the separator roll to assist in retaining the paper web on the inner wire (FIG. 1). The inner wire extends from the separator along a straight run which defines an angle of less than 90.degree. relative to the straight path traversed by the two wires upstream of the separator.

  • Patent number: 4110156
    Abstract: A paper-making machine roll press or mill comprising a suction press roll over which there is trained a press felt, and which simultaneously serves for the direct transfer of a web of paper from a wire. A take-off press roll cooperates with the suction press roll to form a press station. The take-off press roll serves for the transfer of the paper web from the suction press roll and for the delivery thereof to a downstream part of the paper-making machine. An additional press station is provided between the suction press roll and the take-off press roll and is formed by a contact-pressure roll over which there is trained a felt. The contact-pressure roll comprises a hydrostatic flexure adjusting or controlled deflection roll having a shell mounted to be rotatable about its lengthwise axis and displaceable in the press direction relative to a fixed or stationary support.

  • Patent number: 4092916
    Abstract: A controlled-deflection roll having a stationary roll support or carrier and a tubular roll shell rotatable about the stationary roll support. The tubular roll shell bears upon the roll support or carrier through the intermediary of at least one bearing or support element. The roll shell is provided at its ends with guide members which are rotatably mounted in the roll shell and which are guided on the roll support in the direction of the pressing or contact movement or the disengaging or lift-off movement of the roll shell. The controlled-deflection roll is provided with a scraper device equipped with a scraper blade which, during operation, is in contact with the surface of the roll shell, and the scraper device is secured to the guide members.

  • Patent number: 4089739
    Abstract: The plates which define the throat of the head box are movable simultaneously to adjust the size of the exit throat while the angle between the plates is maintained. The adjusting means includes adjusting rods which are slidable lengthwise of the head box and transverse linkages which are pivotally secured to slidable locating members affixed to the plates. Adjusting screws at the throat provide a fine adjustment.

  • Patent number: 4087321
    Abstract: The distribution pipe is of narrowing circular cross-section with an elongated aperture. The pulp guide is mounted via a tongue and groove connection on the pipe to both sides of the aperture in order to hold the pipe together against the peripherally operative tangential force of the pipe. The plates which form the throat can be replaced from time-to-time to change the size of the throat.

  • Patent number: 4071401
    Abstract: The auxiliary roll of the separating system is located downstream of the main roll and is spaced from the main roll at a distance less than 0.25 times the diameter of the auxiliary roll and greater than the combined thickness of the two wires and paper web therebetween, e.g. a distance of 10 millimeters. A separating wall is located between the main roll and main wire on the upstream side to block the entry of air between the main wire and main roll. The spacing of the two rolls ensures a positive separation of the paper web on the main wire.

  • Patent number: 4004968
    Abstract: A wire is passed over the suction breast roll between the formed paper web and the doffer belt or the previously formed paper webs and doffer belt. The doffer felt is disposed in an unencumbered fashion over each of a plurality of consecutive suction breast rolls. The wire is removed from the web at a downstream point outside the dewatering influence of each breast roll. Stripping of the wire from the paper web is aided by various suction devices or couch rolls at this latter point.

  • Patent number: 3947317
    Abstract: The adjusting rod of a lip adjusting mechanism is provided with an indicator which overlies a scale means on which a curved line representative of the lip motion is disposed. Movement of the lip from one position to another is indicated by movement of the indicator along the curved line. A scale is also used with the curved line to measure the displacement of the lip and, thus, the size of the gap defined in part by the lip.

  • Patent number: 3943035
    Abstract: The lip at the outlet of the nozzle duct is mounted along with the adjusting mechanism in a structural unit which is pivotally mounted on the casing. This allows the lip to be moved away from the permeable element to expose the nozzle duct and guide device for cleaning.
