Definitions

  • This invention relates in general to high-speed papermaking machinery and in particular to the slice lip of a papermaking machine which receives its stock from a headbox and directs it toward a fourdrinier wire.
  • the present invention relates to a fluid control for a slice opening of a headbox in which the slice lip is pivotally mounted to the headbox and isposition controlled by using fluid pressure means such as air bags mounted between the slice lip and the main frame member of the machine on which the breast roll is rotatably supported.
  • fluid pressure means such as air bags mounted between the slice lip and the main frame member of the machine on which the breast roll is rotatably supported.
  • FIG. 1 is a side view of a headbox and breast roll of a papermaking machine constructed in accordance with the principles of the present invention with certain parts of the headbox DESCRIPTION OF THE PREFERRED EMBODIMENT
  • the invention is illustrated in FIGS. 1 and 2 wherein a fragment of the forming end portion of a papermaking machine including a headbox that has agitating rollers 11 and 12 mounted therein is disclosed.
  • a lower slice lip 13 is connected to the lower portion 9 of the headbox wall 8 and an upper slice lip 17 is pivotally attached by the pivot pin 14 to the upper edge of the discharge outlet portion 16 of the headbox.
  • An upper slice lip support 18 is connected to the upper slice lip 17 and a fluid pressure adjusting member 19 which might for example be an inflatable chamber is mounted between the support 18 and a deflection beam 21.
  • Compression pads 22 and 23 are mounted on either side of the hydraulic chamber 19 as shown in FIG. I to distribute load over the inflatable chamber.
  • a conduit 24 is connected to the fluid pressure adjusting means 19 and has a valve 26 to regulate the pressure in the fluid pressure means 19.
  • a supply tank 27 is connected to the valve 26 as shown.
  • a breast roll 28 is supported in a conventional fashion adjacent the headbox I0 and a fourdrinier wire 29 passes over the breast roll.
  • brackets 32 that are connected by pins 34 to links 33, For simplicity only one end of the beam 21 is shown but it is to be realized that both ends are supported in the same manner.
  • the second ends of the links 33 are connected to brackets 36 by pins 37.
  • the bracket 36 is mounted on the frame of the machine which also rotatably supports the breast roll 28 in a well known fashion.
  • a dimensional reference means 38 has a first portion 39 that is mounted on the frame of the machine and a second portion 41 which is connected by extension 42 to the upper slice lip 17.
  • the end wall 43 is formed with a suitable slot to allow the extension 42 to move with the slice lip'17.
  • the slice lip 17 may be controlled by adjusting the pressure in the fluid pressure means 19 with the valve 26. Since the deflection beam 21 is connected by the brackets 32 and links 33 to the frame of the machine, the deflection beam 21 does not move relative to the support axis of the breast roll.
  • the fluid pressure means 19 moves the slice lip 17 about the pivot 14 and the position of the lip 17 is indicated by the position dimensional reference 38.
  • a papermaking machine comprising:
  • a breast roll in operative association with the headbox
  • fluid pressure means mounted between said beam and said upper slice lip to adjust the tip of said slice lip relative to said breast roll.
  • a slice lip support is attached to said upper slice lip and said fluid pressure means engages said slice lip support and adjusts said slice lip alonga radial line extending through the axis of rotation of said breast roll by moving said slice lip support.
  • a papermaking machine according to claim 3 wherein said fluid pressure means comprises a flexible fluid container.
  • a papermaking machine comprising a supply tank fluidly connected to the flexible fluid container to control the position of said upper slice lip.
  • a papermaking machine comprising compression pads mounted on either sides of the flexible fluid container to distribute load over the container.
