  • HEB-MANN PALM 0] NEUKOCHEN, NEAR UNTEBKOCHEN, GERMANY- lmciumsm ron cononme Aim Ercnme PAPER wnns AND THE LIKE AND METHOD 'rnnnnor.
  • My invention relates to a method and a mechanism for the application of colors, etching and dissolving liquids, etc., in the form of atterns, on paper webs and the like, prefera ly during the manufacture of the web, i. e. while the paper web is still in the wet state.
  • the ob'ect of the invention is to provide paper we s, especially those of little resistance and which are still in the nascent state with an application of colors or other sorts of liquid in the form of patterns by which existing colors may be influenced.
  • the colors or the like are applied to the web by means of a moistened roll over which the web runs and which is counteracted at the other side of the web by a pressure roll, in order to press the web against the patterns of the sa d moistened roll.
  • the patterns of the latter in this case, have to be built up of solid material such as rubber, metal or the like, in order to withstand the pressure of the said pressure roll.
  • This means is not favorable for the feeding bf the liquid by the pattern roll, as the adhesion of the smooth surface of such materials is not great enough to warrant a suflicient form distribution of same all over the surface, especially when the projecting surfaces of the pattern roll are large.
  • these methods are not applicable to paper webs which are still in the nascent or wet state, as the webs would be destroyed between the two rolls in consequence of t e exerted pressure.
  • Fig. is a diagrammatic section throu h an apphance for the application of the hqquantity of liquid and a uni below that of the uid to the web
  • Fig. 2 is a diagrammatic section throu h a similar appliance showing some additional features for practicing the novel method.
  • Fig. 3 is a side view of the rolls employed in the construction of Figs. 1 and 2.
  • the liquid a to be applied is stored in a basin, in which a transmitting roll 6 is partiall immersed. Above the transmitting roll an in contact with the same is located an application roll 0 which carries on its circumference an absorbing coating 0 in form of the pattern to be transmitted.
  • the web e runs on'the upper side of the application roll a and is guided before and behind the application roll by means of guiding rolls (Z in a suitable manner.
  • the soft and absorbing coating of the application roll would be destroyed in a short time.
  • the adhesion of the transmitting roll 5 may be further increased by a suitable formation of its surface. For this purpose, small grooves of convenient form and depth are provided on the roll. by which a greater quantity of uid is delivered to the application roll;
  • the application roll 0 is supported by'bearings c which are mounted in guides f and arranged for movement towards and away from the centre of the transmitting roll I). Said bearings c are supported by pivoted arms g the free endsof which are adjustable to effect the vertical movement of the roll a with reference to the roll 6.
  • the guiding rolls (1 are preferably ad'ustable in a horizontal direction towards an away from the application roll 0 as well as in a vertical direction. This may be effected by any suitable means not shown on the drawing.
  • the speed of the transmitting roll I) is not bound to that of the ap lication roll 0. Accordingly, the quantity 0 liquid may be regulated by variation of the speed of rotation of either or both of said rolls. In consequence of the want of any immediate contact between the two rolls 6 and c, the coating of the latter is saved to to the utmost; even accidental excentricity is,
  • Fig. 3 the pattern on the roll-c is indicated by the character it, and the textile covering for the roll I) is indicated by the letter 2.
  • an application roll having a liquid absorbing coating on 1t; patterns formed on the said'coating; and a transmitting roll disposed beneath the application roll so as to leave a small distance between the opposing surfaces of the two rolls and a suitable coating of textile on the surface of the transmitting roll.
  • a liquid transmitting roll partially immersed 1n liquid to be applied and rotatable therein whereby to carry a surface film of said liquid
  • an application roll rotatably mounted above said transmitting roll, said application roll being slightly spaced from the transmitting roll and characterized by a soft liquid-absorbent coating formed in patterns, said coating being adapted to transmit the liquid of said surface film to a travelling web bearing on the upper side of the application roll.
  • a liquid transmitting roll partially immersed in a liquid to be applied and rotatable therein to carry a surface film of said liquid
  • an application roll rotatably mounted above said transmitting roll said application roll having a soft liquid-absorbent coating carrying the outline of the patterns and adapted to transmit the liquid of said surface film to a web bearing on the upper side of said application roll to produce the patterns thereon.
  • the method of producing patterns on the surface of wetpaper inthe course of manufacturing and before finishing which consists in supplying to a part having an absorbent surface bearing the desired desi n the material for forming said design on the paper, causin the unfinished wet paper to make contact Wlfil said absorbent surface, causing said paper and said absorbent surface to move so as to transfer the material from said absorbent surface to the surface of the paper and form the design on the latter, and causing the paper to engage the absorbent surface when in contact with same with just enough pressure to enable said material to be transferred to the paper to produce the pattern desired.
