Definitions

  • the invention relates to the pressure loading of blankets in paper making, paper shrinking, fabric shrinking, and other machines, and more particularly to the maintenance of a high loading pressure which is uniformly distributed across the traveling, resilient blanket from edge to edge thereof.
  • the present invention was conceived in connection with the manufacture of uncreped stretchable paper as disclosed in .Cluett Patent #2,624,245. While the utility of the invention is by no means limited to the manufacture of uncreped stretchable paper, the invention is illustratively shown and described herein as applied to that use.
  • the acceleration and subsfiqll int deceleration of the surface of the resilient blanket may be effected by feeding the resilient blanket along its travel to a nip formed by and between a pressure loaded roller and a rotating,
  • the pressure loading roller extends across the Width of the traveling blanket and the surface of the roller travels substantially in unison with the moving blanket.
  • the roller is mounted at its ends in bearings, which bearings are loaded by a heavy pressure in the direction to cause the roller to apply pressure to the traveling blanket to deform the blanket at the nip.
  • the web will tend to pile up in advance of the nip and Will produce wrinkling and other deleterious effects. In every. such case different longitudinal Zones of the web will be treated differently, and the product will be. non-uniform in strength and extensibility and will be likely to be impaired in appearance, surface smoothness and quality.
  • Another conventional expedient used to reduce sagging of the pressure roller is to back up the pressure roller at frequent intervals with idler rolls through which pressure equalizing forces are applied.
  • Such idler rolls travel with the same surface velocity as the pressure roller which complicates the problem of providing suitable bearings for the idler rolls and is apt to prove a bottleneck requiring the entire mechanism to be operated at reduced speed with resulting loss of output.
  • the idler rolls moreover, alter the surface finish of the pressure roller in spaced zones, and wear the pressure roller to an uneven striped contour.
  • the pressure roller of usual construction may be stopped with very little force, and in fact by simply holding the roller by the hands, provided the surface of theconfronting faces of the blanket and roller are sufficiently lubricated. Under these conditions the friction thus, is concerned with both the static and the dynamic Thus, the bearing problems are reduced to those existing during start-up and before the loading pressure is provided on the roller.
  • the pressure roller is made non-rotary.
  • a hydrostatic lubricating film is provided between the resilient blanket and the nonrotary roller to permit initial movement of the blanket over the surface of the non-rotary roller.
  • the depth of the roller may be made greater than the width so as to prevent sagging of the roller when pressure loading is applied, or the pressure loading may be distributed along the non-rotary rod. In this embodiment, bearing problems are wholly eliminated.
  • the pressure cylinder or pressure beam may be either chromium plated, or polished, or coated with Teflon (Du Pont trademark for its polytetrallouroethylene resin).
  • Teflon Du Pont trademark for its polytetrallouroethylene resin
  • An important advantage of employing a non-rotary pressure beam resides in the fact that the depth of the beam may be extended to provide great rigidity without correspondingly increasing the width or diameter extent of the pressure member, as must be done when an end loaded roller is employed. Because of this, a more concentrated pressure is applied to the blanket. This means that a given total pressure will produce a much greater local deformation of the blanket than would be realized if acylindrical roller of the required rigidity were employed, or conversely a given blanket deformation can be obtained with much less total pressure.
  • Another important object of the present invention is to provide a hydrostatic film between a resilient blanket and a non-rotary pressure rod to permit the blanket to move across the surface of the pressure rod without detrimental frictional effects.
  • Another object of the present invention is to provide a non-rotary pressure rod having a greater depth than width for applying a uniform pressure across a traveling, resilient blanket.
  • a further object of the present invention is to reduce bearing and loading problems for a pressure roller.
  • FIG. 1 is a fragmentary view in side elevation, partly broken away, of a portion of a paper making machine in which the preferred embodiment of the present invention is-shown;
  • FIG. 2 is a fragmentary sectional view taken on the line 22 of FIG. 1, looking in the direction of the arrows;
  • FIG. 3 is a detail view in side elevation on a larger scale than FIG. 1, showing the pressure applying member of FIG. 1 in association with the blanket and the drum;
  • FIG. 4 is a view similar to FIG. 3 but showing another form of pressure applying member
  • FIG. 5 is fragmentary view in side elevation partly broken away, showing an alternate method of applying pressure to the pressure member
  • FIG. 6 is a fragmentary sectional view taken on line 6-6 of FIG. 5 looking in the direction of the arrows;
  • FIG. 7 is a detailed view in side elevation on a larger scale than FIG. 1 showing the ends of the pressure applying member of FIG. 1;
  • FIG. 8 is a view similar to FIG. 3 but showing another embodiment of the invention in which the pressure beam is rotatably mounted, and;
  • FIG. 9 is a view similar to FIG. 8 but showing a further modification.
  • FIGS. 1 to 3 disclosure is made of a practical and advantageous form of paper shrinking unit, which embodies features of the present invention.
  • the shrinking unit is not restricted to use in on machine operations, and may be embodied in a converter for shrinking a remoistened, finished web, it is illustrated herein as embodied in a paper making machine and located after the presses and in the drying section.
  • the moist paper web P is shown as supplied from the preceding section of the paper machine, the web being passed, for example, from a feed couple 12 to the shrinking unit 10 over an idler guide roll 14 at a speed corresponding to the intake speed of the shrinking unit.
  • the shrinking unit comprises a rigid nip forming member which is illustratively shown as a steam heated drum 16 of substantial diameter, say four feet.
  • This drum is desirably chromium plated and polished, but other suitable surfaces may be used.
  • the drum is of rigid construction and is connected to a drive shaft 17 which is rotatably driven by any suitable means.
  • the drive shaft is desirably mounted in sturdy roller bearings at each end of the drum. Any available expedient may be resorted to for making the drum and the drum mounting rigid and unyielding.
  • a resilient rubber blanket 18, desirably about one inch thick is mounted on three guide rolls 20, 22 and 24 which are arranged to tension the blanket 1.8.
  • the blanket has a run which travels on a segment of the drum 16.
  • the blanket 18 may have a shore durometer hardness of between 50 and depending upon the application and may be provided with a non-stretchable backing of cord fabric if desired, but this is not essential.
  • the blanket is driven by the drum 16.
  • the rotary parts thus far described are all mounted in rigid side frame members 26 and 28, which members are disposed outside the lateral bounds of the paper web P and the blanket 18.
  • a rigid pressure bar 30 extends across the machine through substantially the full length of the drum 16, being supported at its ends.
  • the pressure bar 30 comprises a thick Walled but hollow metallic cylinder 34 and a rigid beam 36, FIG. 1.
  • the cylinder 34 and the beam 36 are desirably of steel or steel alloy and are .of great strength and rigidity.
  • the cylinder is of small diameter (say about six inches) but the total depth of the pressure bar 30, as constituted by the cylinder 34 and the beam 36, is very considerably greater than the diameter of the cylinder, 34.
  • the cylinder 34 is disposed to engage the back of the blanket 18 and to press the face of the blanket strongly against the drum 16 in position to form a uniform nip for the paper web P. This is the shrinking nip in which the condensation of'the web takes place.
  • the uniform pressure is transmitted to the blanket by loading the ends of the beam 36 and by properly designing the bar 30 to uniformly transmit the loading without deflection, as shown in FIG. 1 and FIG. 2.
  • each of the devices 38 comprises a piston 40, affixed to a piston'rod 44, which is operable by hydraulic or pneumatic pressure in a stationary housing42.
  • the devices 38 are supported rigidly from the side frame members 26 and 28 by suitable brackets '45.
  • Each piston is supplied with hydraulic or pneumatic fluid under pressure through a conduit 46.
  • One expedient consists of coating the surface of the cylinder 34, or at least the blanket contacting area thereof, with chromium, Teflon (Du Pont trademark for its polytetrafluoroethylene resin) or other suitable material.
  • a preferred expedient for reducing friction consists in the furnishing of a lubricant between the confronting faces of the blanket 18 and the bar 30 and in such manner asto provide ahydrostatic and a hydrodynamiclubricat- I.
  • the cylinder 34 is formed with passages 74 which are adapted to deliver lubricant direetly'through 76 or other dependable source.
  • the liquid is drawn from the reservoir 76 through a conduit 78 by a' pump 80 and its delivered under pressure by the pump to a conduit 82.
  • 'Iheeonduit 82 has associated with it a conventional manually adjustable'regulator valve 84, for adjustably controlling the pressure of the lubricant in the conduit 82.
  • the valve 84 is disposed in a return-conduit 822: which runs from the conduit 82 back to the reservoir 76.
  • the conduit 82 is connected todeliver lubricant under controlled pressure to the interior of the hollow cylinder 34.
  • the lubricant may be supplied to the ends of the roll or to various points along the roll if the roll contains internal partitions.
  • the regulator 84 is desirably set to maintain a lubricant pressure of the same order.
  • the reservoir 76 may be omitted and an air pump, rather than a hydraulic pump may be utilized.
  • the system for supplying pressure fluid to the chambers 38 may desirably be similar to the system for supplying and regulating lubricant as described.
  • the shrinkage of the web can be readily understood from a study of FIG. 3. If. the blanket is uniform and the thickness of the space between the bar 30 and the drum 16 is three quarters the normal, undistorted thicknes s-of the blanket, the rubber must pass through the constriction at four-thirds the normal velocity of the web engaging face of the blanket.
  • the higher speed is the i n ake speed of the web, or the speed at which theweb is supplied by the feed rolls 12 for shrinking, and the lower speed is substantially the speed at which the Web travels after being condensed In this'suppositious case I the web wouldbe shrunk 25% and, barring unintended that area of the cylinder 34 which is covered by the blanket 18
  • the lubricant may consist of air or of a suitable liquid.
  • the lubricant should consist of air or water or of oil which does not attack natural rubber, such as the silicone oils. If the blanket is of a synthetic rubber which isresistant to attack by oils derived from petroleum, the silicone oils are still usable but the cheaper'oils derived from petroleum may be used instead.
  • The, passages 74 are uniformly spaced along the face of the cylinder 34 which confronts the blanket 18.
  • the spacing and configuration are determined by the stress distribution in the nip section of the rubber belt.
  • the shape of the passages must be selected so that there is only minimal interference with the surface film of lubricant.
  • FIG. 4 disclosure is made of a pressure bar 30a for cooperating with the blanket 18a and a polished, chromium plated drum 16a. in place of the cylinder 34 a cylinder segment 34a is'provided. Except for the difference in shape between the cylinder 34 of FIG. 1 and the cylinder Slots or large holes will destroy the surface film and blanket. The relief of pressure r'nay permit rubbing of I the blanket at the edges.
  • Lubricating liquid may be furnishedfrom a reservoir segment 34a of FIG. 5, the structure is the same as before.
  • Corresponding reference characters have accordingly been applied to corresponding parts with the subscript a added. in each instance, and no further detailed description will be given. No essential function of the cylinder 34 is sacrificed by the substitution of the seg- -ment 34a.
  • the blanket contacting face of the member 34a be cylindrical in form. It can be elliptical in cross section if desired, or-it can'be varied in other ways. It is essential, however,1that all blanket contacting areas be rounded, since an objectionable snubbing effect would be introduced by any requirement that the blanket turn sharp corners, and the uniform lubricating film would become more diflicult to maintain.
  • FIGS 5 and 6 the general organization .is the same as in FIGS. 1 to 3 but disclosure is made of a modified form of pressure applying means. Corresponding reference characters have accordingly been applied to corresponding parts with the subscript b added in each instance,
