Definitions

  • This invention relates to an apparatus for the production at high speed of white or colgre paper glazed and/or colored on one As is well known in the paper making art,
  • the glazing of paper involves its passage with a determmate content of water over a drycylinder having a polished surface.
  • serious drawbacks were met with in the glazing of paper due-'to the circumstance that the water content of the paper varies considerably with its thickness at the moment of its passage over the final drying cylinder.
  • the paper' employed for moistening the paper may be clear water or it may be water with the addition of colloidal matter adapted to enhance the glazing.
  • the invention permits of replacing papers produced by employment of separate machines independent of the continuous machine.
  • Fig. 1 is a view in elevationshowing diagrammatically the assembly of the apparatus as adapted to be utilized for glazing paper with the use of clear water.
  • Fig. 2 is a corresponding plan view.
  • Figs. 3 andd show modifications of this arrangement, employed in the manufacture of bichrome paper or of paper to be glazed by means of water containing colloidal matter or otherwise prepared.
  • Figs. 5 and 6 show two alternative forms of the device for ensuring distribution of the water or liquid over the paper sheet.
  • F1 7 shows an alternative form especially fort e making of bichromepaper.
  • 1 denotes a reservoir adaptedto contain clear water.
  • This reservoir which is provided with a drain connection 2 with cock 3, feeds by way of a pipe 4 fitted with a regulating cock 5 and a removable sieve 6 a regulator 7 which determines the depth of the water utilized for moistening the paper.
  • the water contained in-the reservoir 1 flows into the regulator 7 by way of an o ening controlled by a valve 8 actuated by a nected to a float 10 soas to maintain a conever 9 conas usual over a guide roller 16 whence it is re-' turned to the paper machine in the usual way, whilst the paper passes first under a distributmg roller 17 and then between the pressure roller 19 and the drying cylinder 18' before turning around the latter.
  • the water flowing from the reservoir 1. to the regulator 7 passes by way of the distributor tu e 13 disposed transversely of the felt above the pa er.
  • This distributing tube 13 being pierce with a large number of holes, the water is distributed over the pa r so as to form a p901 at 20 in front of t e roller or other distributing member 17.
  • the water is thus uniformly distributed over the surface of the paper which immediately thereafter passes into contact with the olished surface of the dr ing cylinder 18 o the paper machine.
  • this water added the paper is brought to the proper degree of humidity and 1s glazed at high speed in the paper machine, f bichrome paper is to be produced there are incorporated in the installation evices shown in Figs. 3 and 4' whereby coloring liquid isintroduced into the reservoir 1.
  • a second reservoir 21 provided with an agitator22 rotated through the intermediary of gearing 23.
  • This reservoir 21 is fitted with a thermometer 24 and receives in its interior a steam coil.
  • the liquid or bath prepared in the-reservoir 21 passes by way of the'pipe 29, the delivery of which is controlled by a cock 30, to the reservoir 1 which may also be provided with an a itator 31 rotated through the intermediary 0% coloring liquid may be prepared in the reser- You 21 while the coloring liquid previousl perspared and contained in the reservoir 1 1s mg utilized in the manufacture of bichrome papgfi.
  • the apparatus is utilized exclusively for the I lazing of paper or for the manufactureof ichrome paper, the distribution of the liquid on the sheet is effected by the distribution regulator 7 co-operating with the perforated tube 13 and withthe'distributthe l or 100 20 which is essential in order to o tain a umform distribution on the surmay also be used if size or colloidal matter is v to be added to the water.
  • roller 17 which ensures the formation of As is understood a like arrnt may be applied to other drying cylinders of the machlne, and in a given case the roller 17 may cooperatewith one or two cylinders in relief not shown so as to apply different colors and designs to the paper.
  • the tube 13 and the roller 17 are preferably mounted so as to be movable at will vertically or laterally by means of adjustable articulated sup orts.
  • a distributing device of other type suitable for the class of paper to be produced for example, for thin aper the perforated tube 13 may be replaced by a channel 33 of V-section as shown in Fig. 5, the lower edges of which channel may be br'oughttogether by adjustment of screws 34 so as to nip a wick offelt 35 which rubs on the paper over its width.
  • the water whether colored or not, is delivered in the form of a regulated jet into the channel 33, prises through the wick and soaks the paper over its surface.
  • Fig. 6 shows a further modification of the distributing device in which a felt wick 35 is nipped at one end between the tube 13 for delivery of the liquid and a round bar 36 held against the perforated tube 13 by pieces 37 fitted with screws 38.
  • the wic 35 rubbing at its' other end over the piper soaks it with liquidreceived from the tu 13.
  • Fig. 7 it may be useful in some cases to make use of two rollers 17 and 17 carried by a fulcrumed support whereby the may be raised or, lowered separately or rought nearer to or spaced apart from each other at will according to the necessities of manufacture in order to obtain the best distribution of the coloring substance.
  • the rubbing of the paper may cause this second roller 17 to rotate in the same direc- -tion as the roller 17. It may however be rotated in an inverted direction by means of a crossed cord passing on two little ooved pulleys mounted on one end of the axis of the rollers.
  • rollers 17'and 17' may eventually be replaced by a scraper in polished glass on 'a coloring solution arran ed contained names:
  • a paper making-machine the combination for treating one surface of the paper comprising, in combination, a pressure roller, a drying cylinder, a felt, a sheet of paper passin between the said pressure roller and the said drying cylinder, a distributor for in front of the aper passes beler and the said point where the sheet 0 tween the said pressure r0 drying cylinder and across the sheet of paper, a roller disposed between the said drying cylinder and the said distributor and against which a pool is formed, whereby the distribution of the coloring solution is made uniform on the said sheet of paper, a regulator whereby the delivery of liquid is controlled, a pipe extending between the said regulator and the said distributor, means whereby a constant level is maintained in the said regulator, a reservoir connected to the said distributor and in which a charge of the coloring solution is contained, a second reservoir,
  • the combination for treating the surface of the paper comprising a cylindrical dryer, a felt for.
  • the combination for treatin the surface of the paper comprising a cylindrical dryer, a felt for guiding thepaper over the surface of the dryer, a roller in advance of the said dryer relative to the direction of travel of the felt, the said felt and sheet of paper guided thereby being caused to take a downward path before reaching the roller, a liquid distributor in advance of the said roller extending across the entire width ofthe paper, for distributing a liquid along the whole width of the sheet of paper and in the fold formed by the roller and the sheet of paper to f in the said fold, and means for controlling the distribution of the liquid.
