T 0 all whom it may concern:
Be it known thatl, HERMAN ELsAs, a citizen of the United States, and a resident of the city of NewYork, in the county of New York and State of New York, have invented certain new and useful "Improve-- ments in Multiplex Fourdriniers; and I do hereby declare that the following is a full, clear, and exact description of the same,
reference being had to the accompanying.
drawings, and to the numerals of reference marked thereon, which form a part of this specification. 4 x I This invention relates more particularly to a paper making machine wherein a mul-'- tiplex sheet of paper' may beireadily and cheaply produced by means of a plurality ,of Fourdrinier t pe paper making machines disposed at cifi'e'rent elevations-with the wires running in the same or in different directions to permit the webs of paper to be brought into contact and felted together either at the couch rolls or at the first press movement of\ the wires.
rolls depending upon, the relative positions of the Fourdriniers and the direction of It is an object of this invention to remove \webs Of'paper from a plurality of Foura pal'urlity of Fourdriniers driniers by means of aplurality of felts.
It is also an object of thetinvention to provide a method of producing a sheet of paper. by felting togetherwebs of paper'by using positioned one above the other. I I 1 It is a further object of this invention to arrange a plurality of Fourdriniers one above the other so'that the Fourdrinier wires will conduct 'paper webs into the fields of operation of either the couch rolls ofone of the Fourdriniers or "the first set of press rolls.
"It is furthermore an object of the invention to produce a sheet of paper with the ,tWo sides of different colored paper having af fine formation and the other qualities which can only be deri'vedfrom Fourdrinier yp of machines. It is an important object of this invention to provide a' machine adapted to readily make paper constructed with, opposite sides of difieren'tgrades and finish of paper and of different colorsif desired,--said paper being readily produced by the novel arrangement of a plurality ofFourdriniers positioned at different elevations with each Fourdrinier having a felt co-acting there- 1924.

this invention will be apparent from the disclosures'in the specification and accompanylng drawlngs.
The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. a v

Figure 2 is a schemat c of a modified arrangementfor a multiplex Fourdrinier -ma chine.
v As shown on the drawings: Referring to the machine arrangen'ient illustrated in FigureI, the reference .numeral 1 indicates-the main machine room floor, while the reference numeral 2 indicates an upper. flotgr. Mounted on the upper floor 2 is anvupp r Fourdrinier briefly comprising a breast box' 3, a deckle mechanism 4 and an upper Wire 5. The upper wire 5 passes around a breast roll 6 and over table rolls T'and wire supporting and guide rolls 8. The wire 5 also passes between alower couch roll 9 and an upper couch rolh 10. An upper pickup felt 11 is trained around upper felt carrying rolls 12 and lower feltcarrying rolls 13,
The upper felt 11 passes through openings 14: and 15 in the-upper floor 2;
Mounted upon the main or lower floor 1 below the upper-Fourdrinier is ja lower Eourdrinier briefly comprising a breast box 16, a deckle mechanism 17 and a lower wire 18." ,The lower Wire 18 passes around a breast roll 19 and over tab-l'e rolls 20. The
lowerwire 18 passes between a low crjcouch-v roll 21 and an upper couch roll 22, between which the upper felt 11 also passes. A lower pickup felt 23 is trained around felt carrying rolls 24. The upper felt 11 an'd -the lower felt 23 pass through the nip of a first set of press rolls 25 and 26. The upper felt 11 comes in contact with the lower felt 23 at apoint just previous. to {entering thenip" of the press rolls 25 and 26; A second set of press rolls; 27 and 28 are provided between the nip of which the. upper felt which have been felted together.
passes after parting from the lower felt.
After leaving the press rolls and 26, the
upper felt carries the two webs of paper the fibres and giving a higher finish to the. sheet.
From the smoothing rolls 31 and 32 the sheet of paper passes through the dryers 33 and calender-s which give the finish to the paper.
In ,the arrangement of the Fourdriniers illustrated in Figure 1, the 'wires 5 and 18 both travel in the same direction and conduet webs through the nip of the couch.
rolls 21- and 22 of the lower Fourdrinier. The webs are thus felted together into one sheet and carried through the nip of the press rolls 25 and 26 to be further felted 1 together before being conducted through dryers 33.
Figure 2-1llustrates a modified arrai'ige-- the press rolls 27 and 28, between the smoothing rolls 31 and 32 and through the ment of a multiplex paper making machine with the upper Fourdrinier mounted on the main machine room floor 34 and with the second Fourdrinier placed in the basement on the floor 35 and reversed so that the upper wire 36 and. the lower wire 37 travel in opposite directions. paper, after-passing through the respective nips of the'upper set of couch rolls 39 and the lower set-of couch rolls 40, are brought together at the felt carrying roll 4-1. in this arrangement the upper web of paper is carried "b the upper felt 42 from the upper Four rinier, while the lower web of paper is carried by the lower felt as from the lower Fourdrinier and the two webs are fel'ted tog'ether by passing through the nips of-the first set of press rolls 44. The felted webs are carried along by the upper felt 42lthrough the nip of a second set of press rolls 45 and 46. The upper press roll 45 has a metal surface to which the paper clings, while the felt 42 parts from the paper andreturns to the couch rolls 39. From the press roll 45 the felted webs of The The two webs of:
masses paper then pass over a smoothing roll 4!? and then between the nip of smoothing rolls 47 and 48 which act to further cement the two webs together and at the same time lay-' ing down the fibres. The paper next passes through the dryers 4}) and calendars which give the desired finish to the paper. This arrangen'ient produces a parti'cularly'strong product since the operation of the Fourdrinier parts in opposite directions bring about a crossing and interlacing of the fibers which isivery desirable.
YVhile two multiplex arrangements have been illustrated and described whereby a plurality of webs of paper from a-plurality' of Fourdriniers at different levels can. be felted or molded together to produce a multiplex sheet of paper, itwill of course be understood that many different arrangements of the felts, the couch rolls, the press rolls, and dryers with respect to one an other maybeused without departing from the principles of this invention.
Multiplex sheets of paper of different kinds, and quality may be readily produced by the multiplex Fourdrin'ier arrangement, as wellas' multiplex paper having different colors on opposite sides.
I am aware that numerous details of con str-uctlon may be Varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted otherwise than'necessitated by the prior art.
I. claim as my invention: 1. A multiplex paper making part of said Fourdriniers and adapted to runrin diiferentdirections, couch rolls co acting with each of said Fourdriniers,. sets ofpress rolls, anda plurality of felts comachine comprising a plurality of Fourdrmiers' -mounted one above the other, w1res forming Bill acting with the couch .rolls and with the press rolls for removing webs of paper from said Fourdriniers to felt said webs of paper togetherat the first set of said press rolls.
2. In a multiplex F ourdrinier paper maehme, the combination withla plurality of F ourd-rinier wires running in opposite directions and located at different levels, of a pick-up felt coacting with each Wire toreniove a web of paper therefrom, and a pair I of press rolls for pressing said felts to mould said webs of paper together.
Intesti'mony' whereof I have hereunto subscribed my name. ELSAS.
