PROVISIONAL DI MUIFICATION.
Process for the Manufacturing of Machine-paper with Coloured
Longitudinal Stripes.
I, ADOLF COHN of 15 Schillerstrasse, Breslau, in the Kingdom of Prussia,
German Empire, Merchant, do hereby declare the nature of this invention to be
as follows:-
:-
The object of this invention is a process for the manufacturing of paper,
consisting of coloured longitudinal stripes of different colours by the long sieve-
machine.
The new process is the following:
Several materials, coloured according to the stripe colours desired, are allowed
to run upon the wet part of the machine so that the edges of the separate stripes
are felted under the action of the shaking of the sieve or other suitable arrangements
thus producing a durable striped paper.
Each of the two materials blue and white has to pass a purifying part and is
then conducted in stripes of the desired largeness to the sifting part. The material,
for example, may be allowed to fall from a channel through openings into the
purifying part, a short distance in front of the sieve. The separation of the stuff
stripes is effected by very thin plates, which may be slided upon a horizontal shaft
or by boundary straps. These parts separating the stuff stripes from each other,
end suitably at that point of the sieve, which contains so much moisture as to
secure a sufficient volubility of the fibres for the felting of the same.
The number of colours chosen and therefore of stuff quantities may be applied,
as one thinks best, also the colours of course. It is only necessary, that the
different stripes of stuff are joined on the wet part of the machine in the manner
that a felting of the different stripes takes place at the joining point.

Process for the Manufacturing of Machine-paper with Coloured
Longitudinal Stripes.
1 ADOLF COHN of 15 Schillerstrasse, Breslau in the Empire of Germany,
Merchant 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 :-
My invention relates to a method of manufacturing paper on the long-sieve
machine, such paper consisting of long strips coloured through and presenting
various colours.
The new method consists in providing for several stuffs, which are coloured in
conformity with the desired tints of the strips, to run upon the wet part of the
machine in such a manner that the edges of the several strips will be felted together
itemani

page_text: under the action of the shaking movement of the sieve or other appropriate devices
and thus produce durable striped paper.
An arrangement of a paper making machine adapted for carrying out this
method is represented in the accompanying drawing,
Figure 1. being a longitudinal section and Figure 2 a plan of the same.
In the drawing I have shown a portion of a machine for manufacturing paper
with longitudinal strips having two different colours, a being one, say the white
stuff, and the other, say the blue stuff.
Each of these two stuffs after passing through the cleaning part, is conducted in
strips of the desired width on to the sifting part. In this case one stuff b may for
instance be caused to drop from a channel c into the cleaning part a short distance
in front of the sieve through openings d.
The separation of the strips of stuffs from each other takes place by very
thin plates e which are arranged upon a horizontal shaft f so that they may be
displaced thereon or also by cover straps. These platese which separate the strips
of stuff from each other come to an end preferably on that portion of the sieve at
which the moisture contained in the stuffs is still so great that a sufficient
movableness of the fibres will exist for the felting.
The number of the colours chosen and therefore of the strips presenting different
colours is optional, and of course the colours may also be selected at will.
The only condition is that the union of the several strips of stuff shall be effected
upon the wet part of the machine and in such a manner that, at the place where
they join, the several strips shall be felted together at their edges.
The above-described method may also be employed for the manufacture of paper
in which the longitudinal strips coloured through are provided upon a common
width of stuff having one colour as a ground. The new product thus obtained
constitutes paper consisting of a double layer, the lower layer being a width of
stuff which presents a single colour and extends over the entire width of the sieve,
whereas the upper layer of stuff is formed of juxtaposed longitudinal strips.
Such paper is specially adapted for the manufacture of wall paper.
Figures 3 & 4 in the drawing show an arrangement in a long sieve machine
suitable for manufacturing such paper. That portion of the machine which joins
the cleaning part is similar to the arrangement represented in Figures 1 & 2,
and the layer of stuff a' having a single colour and serving as a ground passes out
in the customary manner. At the part of the machine where this stuff still contains
a sufficiently large quantity of moisture to allow of the fibres being felted together
in the vertical direction, the differently coloured stuffs b and c are caused to pass
upon the lower width of the stuti a¹ in the same manner as before set forth for
the manufacture of paper consisting of one layer and presenting longitudinal stripes
coloured through. On the width of stuff a' are therefore formed longitudinal
stripes be coloured through, the latter being felted together at their edges and
also united with the lower width of stuff a¹ under the action of suction boxes, sieve
rollers or other suitable auxiliary devices.
Having now particularly described and ascertained the nature of my said inven-
tion declare that what I claim is ;-
--
1. A method of manufacturing paper consisting of one layer of stuff with
longitudinal stripes coloured through, characterized by the feature that differently
coloured stuffs are caused to pass from inlets of widths corresponding to the
dimensions of the several stuffs on to the sieve in such a manner that the union of
the neighbouring strips of stuff a and b will take place at their edges under the
action of the shaking movement of the sieve.
2. A modification of the method described in the first claim, for the purpose of
producing paper consisting of a double layer at its surface with longitudinal stripes
coloured through in such a manner that the differently coloured widths of stuff b
and c¹ are caused to pass upon a width of stuff a' having one colour, run on to the
sieve in the ordinary manner and forming a ground, and that the upper widths of

page_text: stuff b and c are then united with the lower width a by suction apparatus or other
mechanical means whilst the felting together of the upper widths of stuff 6' and c¹
takes place at their edges under the action of the shaking movement of the sieve.
