Year: 1880

page_text: LETTERS PATENT to Emile Dordet, of Saint Junien, in the Department of
La Haute Vienne, in France, Manufacturer, for an Invention of "IMPROVEMENTS
IN DOUBLE SIDED DRYING FELTS, APPLICABLE TO PAPER MAKING"
PROVISIONAL SPECIFICATION left by the said Emile Dordet at the Office.
of the Commissioners of Patents on the 19th November 1880.
EMILE DORDET, of Saint Junien, in the Department of La Haute Vienne, in
France, Manufacturer. "IMPROVEMENTS IN DOUBLE SIDED DRYING FELTS,
APPLICABLE TO PAPER MAKING."
The felt forming the subject of the present Invention is double faced or sided;
it is manufactured by the looms at present in use for these kind of fabrics, one
face or side is made with a cotton or thread warp and cotton or thread weft,
whatever may be the nature of the cotton, flax, or hemp thread employed.
The other face or side is made with a wool weft, and by this combination a
drying felt is produced with double face for use in the manufacture of paper, the
two sides formed of different matters, one of which serves as lining to the other is
of thread or cotton, and the other all wool, which forms the dryer properly so
called.
The advantages of this peculiar method of manufacturing drying felt, one side
being a mixture of cotton and thread, and the other wholly wool, is its superiority
over other felts made entirely of wool, and its durability, and it is in the manu-
facture of the finer kinds of paper that this new felt is calculated to supersede the
wool drying felts at present employed, it being superior also to others in its
economy, the cost being considerably less than felts wholly wool.

EMILE DORDET, of Saint Junien, in the Department of La Haute Vienne, in
France, Manufacturer. "IMPROVEMENTS IN DOUBLE SIDED DRYING FELTS,
APPLICABLE TO PAPER MAKING."
The felt forming the subject of the present Invention is double faced or sided; it
is manufactured by the looms at present in use for these kind of fabrics, one face
or side is made with a cotton or thread warp, and cotton or thread weft, whatever
may be the nature of the cotton, flax, or hemp thread employed.
The other face or side is made with a wool weft, and by this combination a
drying felt is produced with double face for use in the manufacture of paper, the
two sides formed of different matters, one of which serves as lining to the other is
of thread or cotton, and the other all wool, which forms the dryer properly so
Called.
The advantages of this peculiar method of manufacturing drying felt, one side
being a mixture of cotton and thread, and the other wholly wool, is its superiority
over other drying felts made entirely of wool and its durability, and it is in the
manufacture of the finer kinds of paper that this new felt is calculated to supersede
the wool drying felts at present employed, it being also superior to others in its
economy, the cost being considerably less than felts wholly of wool.
This novel kind of drying felt is incontestably superior to felts wholly cotton, or
all thread, as paper made by its employment is as fine as that made where drying
felt wholly wool is used, and it can be indifferently employed in the manufacture
of all classes of paper by all manufacturers.
I claim as my Invention the manufacture of drying felts having a double face,
one of its sides serving so to speak as a lining to the other, being cotton or thread
with weft of cotton or thread, and the other side all wool.
In witness whereof, I, the said Emile Dordet, have hereunto set my hand
and seal, this Fourteenth day of May, in the year of our Lord One thousand
eight hundred and eighty one.
