Improvements in and relating to the Manufacture of Felted Fabrics..
I, LEON ALLART, of 95 Boulevard Beaumarchais, Paris, in the Republic of
France, do hereby declare the nature of this invention to be as follows:
My invention relates to an improved fabric which I obtain by juxtaposing under
special conditions felt and a very thin unsized stuff. As the juxtaposition of felt
increases the thickness of the stuff also its strength, I may utilize, for instance for
clothing, stuffs which it has not heretofore been possible to employ for this purpose.
It is necessary that the felt shall be of one piece with the stuff in order that the
product resulting from the juxtaposition may have the exterior appearance of a
single fabric.
For obtaining this result I proceed in the following manner: During its
manufacture the felt is at a certain moment obtained in the form of carded material;
that is to say, without being completely finished, it presents already the appearance
of a continuous pile, without having the desired consistence, which property is
ultimately given to it by its passage through the felting apparatus and by pulling,
to which it is subjected, according to the purposes for which it is designed.
To manufacture my improved fabric I arrange the carded material upon a roller
placed in front of the felting apparatus by the side of a second roller which receives.
the very light unsized stuff herein before referred to.
Between the rollers of the felting apparatus I pass at the same time the fabric
and the carded material, the pressure exerted by the felting apparatus compels the
fabric to be applied. exactly upon the carded material, the pile of which passes
between the threads composing the fabric, so that I obtain, after this operation, a
fabric of a special kind, one of the surfaces of which is formed by a stuff with a
design and various stripes, whilst the other surface is of ordinary felt, the interior
being constituted by the entangling of the fabric and the carded pile, this entangle-
ment being so intimate that after the last operation above described, the stuff cannot
be separated from the carded pile.
If the felt and the stuff employed do not absolutely form one piece after a first
passage through the felting apparatus they may be subjected to a second pressure
in another felting apparatus placed behind the first. Should it be necessary, the
number of these apparatus is increased in order that after its passage through the
last felting apparatus, the carded pile shall be completely incorporated with the stuff.
The fabric thus obtained is subsequently subjected to the operations which are
usual in the manufacture of felt.
These fabrics may be made by means of any stuffs and the carded pile may
consist either of wool, cotton or any textile substance which can be felted."

COMPLETE SPECIFICATION.
Improvements in and relating to the Manufacture of Felted Fabrics.
I, LEON ALLART, of 95 Boulevard Beaumarchais, Paris, in the Republic of
France, 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 an improved fabric which I obtain by juxtaposing under

page_text: special conditions felt and a very thin unsized stuff. As the juxtaposition of felt
increases the thickness of the stuff and also its strength, I may utilize, for instance
for clothing, stuffs which it has not heretofore been possible to employ for this
purpose. It is necessary that the felt shall be of one piece with the stuff in order
that the product resulting from the juxtaposition may have the exterior appearance
of a single fabric.
For obtaining this result I proceed in the following manner: During its manu-
facture the felt is at a certain moment obtained in the form of carded material,
that is to say, without being completely finished it presents the appearance of a
continuous pile, without having the desired consistence, which property is ultimately
given to it by its passage through the felting apparatus and by fulling to which it
is subjected according to the purposes for which it is designed.
To manufacture my improved fabric I arrange the carded material upon a
roller placed in front of the felting apparatus by the side of a second roller which
receives the very light unsized stuff herein before referred to.
Between the rollers of the felting apparatus I pass at the same time the fabric
and the carded material; the pressure exerted by the felting apparatus compels
the fabric to be applied exactly upon the carded material the pile of which passes
between the threads composing the fabric, so that I obtain, after this operation, a
fabric of a special kind, one of the surfaces of which is formed by a. stuff with a
design and various stripes, whilst the other surface is of ordinary, felt, the interior
being constituted by the entangling of the fabric and the carded pile, this entangle-
ment being so intimate that after the last operation above described the stuff cannot
be separated from the carded pile.
If the felt and the stuff employed do not absolutely form one piece after a first
passage through the felting apparatus they may be subjected to a second pressure
in another felting apparatus placed behind the first.
Should it be necessary, the number of these apparatus is increased in order that
after its passage through the last felting apparatus the carded pile shall be com-
pletely incorporated with the stuff.
The fabric thus obtained is subsequently subjected to the operations which are
usual in the manufacture of felt.
These fabrics may be made by means of any stuffs, and the carded pile may
consist either of wool, cotton or any textile substance which can be felted.
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 :-
:-
First. The improved fabric hereinbefore described and especially characterized
by the combination of a light stuff which is little suited for the best side having
various designs and colours, with a carded pile, which is ultimately felted and which
gives to this fabric the desired thickness and strength, the said fabric being
composed on one of its sides of a stuff, in the middle of an entanglement of stuff and
felt, and on the other side of felt.
Second. The method of manufacturing the improved fabric, which consists in
placing the light stuff upon the carded pile and submitting the whole to successive
felting operations.
