PROVISIONAL SPECIFICATION.
An Improved Manufacture of Paper, Leather, or other Fabric, or
the like, Coated with Adhesive Material.
I, ERNEST AUGUSTE ZUBER, of Rixhem (Alsace) in the Empire of Germany,
Paper Manufacturer, do hereby declare the nature of my invention to be as
follows:-
All the gum-coated papers, or fabrics which are used at present, are covered with
a.uniform and uninterrupted layer of gum' or sizing material Paper covered in
such a manner is firm, stiff and therefore cannot be used in many cases where
softness and flexibility is essential. Moreover, the paper or other substance,
coated in this manner, requires a certain amount of water for making it adherent.
These drawbacks of the paper or fabric now in use, enumerated above, are
caused by the uniformity of the layer of gum or other adhesive medium placed on
one or on both sides of the paper or fabric.
To obviate these drawhacks I use instead of the smooth surface of the present layer
of gum a granular surface, and the present application for a patent has for its
object to insure to me the exclusive property of a new "gummed" paper or fabric,
which is characterised by a rough or granular surface of gum or of sizing material.
This rough surface is produced by the formation of an infinite number of small
projections of the gum or adhesive matérial connected by a thinner layer of the
same.
My new paper with granular surface is obtained by making the continuous sheet
of paper, to be covered by a layer of gum or other adhesive material, pass over a
roller, the surface of which is provided with a number of small cavities arranged-
in a regular or irregular way and filled with gum or other adhesive material,
whereas the surface of the roller between the cavities has no trace of this matter,
or has only a very thin layer thereon.
This roller, the surface of which is provided with a number of small cavities is
the essential device for manufacturing my improved fabric. Otherwise the whole
of the paper-making machine can be varied as desired.
As one example of the manufacture, paper is wound off a roll and passed on to
a cylinder, the surface of which has the above mentioned cavities in it. A roller.
called a feed roller, which dips into a vat or tray, containing, adhesive' material
rubs against the cylinder and fills the cavities thereon with that material
A scraper rubs against the surface of the cylinder and takes off all or nearly all
the adhesive material from the surface of the said cylinder between the cavities.
The paper passes, as I said before, over the cylinder against which it is pressed
by a drum covered with felt. The paper which takes up the adhesive material
from the cylinder, passes thence through a drying apparatus and can be wound into
a-roll.
In the above described example I have only considered the manufacture of
gummed or similar paper with a rough surface, but the new part of my product is
exclusively the nature of the treated surface and not the material on which this
surface is produced that is why F reserve to myself the right to obtain in' the
same manner any fabrics leather, or other like material with granular surface...
My paper with granular surface is very soft, not breakable and adheres easily if
slightly wetted. In consequence it cap he used in many cases, in which the
existing, paper with smooth surface could not be used.

page_text: For certain uses the smooth quality of the sized paper was a drawback. For
instance, in telegraphic apparatus, in which the movement of the strip of paper, on
which the signs are printed, ought to be very regular, which is not the case if sized
paper with smooth surface is used. My paper, on the contrary, can be advanced in
a very regular manner, owing to its rough surface.

An Improved Manufacture of Paper, Leather, or other Fabric, or
the like, Coated with Adhesive Material.
I, ERNEST AUGUSTE ZUBER, of Rixhem (Alsace) in the Empire of Germany,
Paper Manufacturer, 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 :—
D
All the size-coated papers, or fabrics, which are used at present, are covered
with a uniform and uninterrupted layer of gum or adhesive material. Paper
covered in such a manner is firm, and stiff, and therefore cannot be used in many
cases where softness and flexibility is essential. Moreover, the paper or other
substance, sized in this manner, requires a certain amount of water for making it
adherent.
These drawbacks of the paper or fabric now in use, enumerated above, are
caused by the uniformity of the layer of gum placed on one or on both sides of
the paper or fabric.
To obviate these drawbacks I use instead of the smooth surface of the present
layer of gum, a granular surface, and the present application for a patent has for
its object to insure to me the exclusive property of a new "sized" paper or fabric,
which is characterised by a rough or granular surface of gum or of adhesive
material. This rough surface is produced by the formation of an infinite number
of small projections of adhesive material connected by a thinner layer of the same.
The new paper with granular surface is obtained by making the continuous
sheet of paper, to be covered by a layer of gum or other adhesive material, pass
over a roller, the surface of which is provided with a number of small cavities
arranged in a regular or irregular way and filled with gum or other adhesive
material, whereas the surface of the roller between the cavities has no trace of this
matter, or has only a very thin layer thereon.
This roller, the surface of which is provided with a number of small cavities is
the essential device for manufacturing the improved fabric. Otherwise the whole
of the paper-making machine can be varied as desired.
As an example of the manufacture, paper is wound off the roll A and passed on
to a cylinder D, the surface of which has the above mentioned cavities in it.
A roller E, called a feed roller, which dips into a vat or tray F, containing
adhesive material, rubs against the cylinder D and fills the cavities thereon
with adhesive material. A scraper C rubs against the surface of the cylinder D
and takes off all or nearly all the adhesive material from the surface of the said
cylinder between the cavities.
The paper passes, as stated before, in contact with the cylinder D against
which it is pressed by a drum B covered with felt. The paper which takes up the
adhesive material from the cylinder D, passes thence through a drying apparatus
and can be wound into a roll.
In the above described example I have only considered the manufacture of
adhesive coated paper with a rough surface, but the novel feature of my invention

page_text: is exclusively the nature of the sized surface and not the material on which this
surface is produced. That is why I reserve to myself the right to obtain in
the same manner adhesive coated textile fabrics, leather, or other like material or
fabric with granular surface.
This paper with granular surface is very pliable not breakable and adheres
easily if slightly wetted. In consequence it can be used in many cases, in which
the existing adhesive coated paper with smooth surface could not be used.
For certain uses the smooth quality of the coated paper was a drawback. For
instance, in telegraphic apparatus, in which the movement of the strip of paper, on
which the signs are printed, ought to be very regular, which is not the case if
paper with smooth surface is used. My paper, on the contrary can be advanced in
a very regular manner, owing to its rough surface.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A new product obtained by covering paper, textile fabric, leather, or other
similar substance with a layer of gum or other adhesive material, having a granular
surface, produced by the formation on the material treated, of an infinite number
of small reliefs or projections connected by a thinner layer, substantially as
described.
2. A process for obtaining on paper, leather, textile fabrics and other similar
substances a layer of gum or other adhesive material with a granular surface, the
said process being characterised by the passage of the substance to be sized over a
cylinder provided with a number of cavities, having the form of grains, and placed
very close to each other, the adhesive material or gum being supplied to the
cylinder, so as to fill up only the recesses and not the parts of the cylinder
between the recesses, substantially as described.
