I, Lars Gustaf DANIELSON, manager of the paper manufactory Nygvarn, near
Söderteljo, in the Kingdom of Sweden, do hereby declare the nature of this invention
to be as follows:-
Into the receptacle A of a common cylinder wire gauze paper machine, is introduced a
mass perfectly sized or glued, and into the receptacle B is introduced a mass not sized.
When the endless paper formed on the cylinders C and D is united in the usual way
on a blanket, and under pressure of the roller E to one endless paper, passing then
through the presses and drying apparatus of the paper machine, a paper is produced
which on the one side is perfecily sized and on the other side unglued or unsized.
By glueing or sizing the masses in the different receptacles more or less between
perfectly glued or sized and not glued or sized, a number of modifications are produced
of this paper suitable for different purposes.

page_text: improved Papers and methods of manufacturing the same.
I, LARS GUSTAF DANIELSON, Manager of the Paper Manufactory Nygvarn near
Södertelje in the Kingdom of Sweden 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 statenient :—
The invention relates to an improved paper sized on one side, and unsized on the
other, or more impregnated with size on one side than the other, and methods of
making the samo.
The drawings filed with the provisional specification represent a sectional elovation
of a cylinder wire cloth paper making machino. Into the pulp receptacle A. is
introduced a mass thoroughly sized, and into the receptacle B is introduced a mass
unsized. The pulp is fed from the receptacles A and B on to the endloss wire
web by the cylinders O and D, and the two layers of material (one sized and the
other unsized) are united in the usual way on a press blanket F, under pressure
of the roller E. The paper then passes through the presses and drying apparatus
of the paper-making machine, and a sheet of paper is produced, which on one side
is perfectly sized, and on the other side unsizod.
By varying the quantity of glue or size which is mixed with the pulp or mass
in the differont receptacles, a number of different kinds or qualities of this paper can
be produced, suitable for different purposes.
Having now particularly described and ascertained the nature of tho said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
The method of manufacturing paper sized or glued on the one side, and unsized
or unglued on the other, or more impregnated with size on one side than the other,
which consists in manufacturing in a double cylinder endless wire web paper
machine, two layers of paper one sized and the other unsized, or the one more
impregnated with size than the other, said layers of paper being received from the
respective cylinders upon one and the same pross blanket, and then passing together
through tho press and drying apparatus of the machine, by which paper of the said
proporties is produced, substantially as described.
Dated this 22nd day of March 1889.
