A communication by EUGEN FÜLLNER, of Warmbrunn, Silesia, in the Empire of
Germany, Paper Machine Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors 6 Lord Street Liverpool and 6, Bank Street, Man-
chester, both in the County of Lancaster and 323 High Holborn in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention has for its object an improved paper making machine in which
there are three wire webs or aprons.
On the accompanying drawings the three sieving parts are indicated by I,
II, and III. The part I forms, in the usual manner by means of the inflow-box
for the material or pulp a', register b', covering piece c³, and two or more suction
appliances d', a paper web which passes over or round the upper pressing roller
into the press A. The part II forms in the same way a web which usually passes
into the press A. In the action of this press A. the paper webs of the parts I and II
are united to a web which remains suspended on the sieve s² of the sieving part II.
The part III forms in the same way a paper web, and all the three webs formed
by the three sieving parts are united in preliminary pressure press D to a paper
web which is gradually compressed and freed from moisture by the presses D'
D² D³.
the number of which may be adjusted to suit the thickness of the
paper, and then passes under the press B and from there as a paper web is conveyed
to the first press C.
It is of course evident that by removing the sieve s¹ of the part I two webs
may be formed by means of the sieving parts II and III, and may be united to form
one.
It should be noted that each pressing press unites two paper webs so that the
combined paper web may if desired not only be taken off at B but also at the
stretching roller and eventually conveyed to the press which in this case is arranged
under the part I.
The industrial advantages of the three sieve paper machine are as follows.
1. It enables paper, cardboard, pasteboard, etcetera, to be produced of different
material and colour on both sides, and any other filling material in the centre.
2. It renders possible the manufacture of card- and paste-boards of a thickness
(strength) such as could not hitherto be obtained on the long sieve machines.
3. The three sieve paper machine delivers fancy papers and pasteboards complete
direct from the paper machine, which formerly were made by means of various
machines at greater expense and with more trouble, although incompletely.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is ;-
An improved paper making machine in which the two first sieves (s' 8³), each
independently forming a paper web, are conveyed in the same direction round the
upper or lower roll of a pressing press, and the second sieve (52) together with a
third sieve (s) forming a third independent paper web, runs through the same
preliminary presses (D, D¹, D³) and the same second pressing press (B), in such a
way that the union of the two first long-sieve paper webs is brought about by

page_text: means of the first pressing press (A), and the union with the third paper web, by
means of the preliminary pressing rollers and the second pressing press all substan-
tially as herein before described.
