Improved Sheet-material adapted for use as a Non-conductor or feat.
We, JOHANN BARDACH and RICHARD VON STERN, both of 30 Knollgasse, Vienna,
X, Austria, Manufacturers, do hereby declare the nature of this invention to bo
as follows:-
This invention relates to sheets of straw, sea-grass, pampas-grasses and the
like, adapted for use in all cases where bad conductors of heat are needed.
These sheets may be of any desired length and are usually made of a breadth
that corresponds to the length of the stalks. They consist essentially of a layer
of parallel stalks, which is covered on either one side or both sides with jute or
some other suitable woven fabric and is pressed and sown jointly with the fabrio
covering or coverings.
The operatious of pressing and sewing may take place simultaneously or one
after the other; the seams pass through the layers of stalks and fabric and aro
preferably made at right angles to the direction of the fibre of the straw or grass
stalks and consequently at right angles to their longitudinal direction.
In this way there is produced a more or less firm sheet of any desired length,
which is made of any desired thickness from 3 mm. upwards, according to the
purpose of which is is designed to be used and is adapted for use as material
for preventing the passage of heat.

Improved Sheet-material adapted for use as a Non-conductor of Heat.
We, JOHANN BARDACI and RICHARD VON STERN, both of 30 Knollgasse, Vienna
X, Austria, Manufacturers, 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:-
This invention relates to sheets of straw, sea-grass, pampas-grass, and the
like, adapted for use in all cases where bad conductors of heat are needed.
These sheets may be of any desired length and are usually made of a breadth
that corresponds to the length of the stalks. They each consist essentially of a layer
of parallel stalks, which is covered on either one side or both sides with jute or
some other suitable woven fabric and is pressed and sewn jointly with the fabria
covering or coverings.

page_text: The operations of pressing and sewing may take place simultaneously or one
after the other; the seams pass through the layers of stulks and fabric and are
preferably made at right angles to the direction of the fibre of the straw or grass
stalks and consequently at right angles to their longitudinal direction.
In this way there is produced a more or less firm sheet of any desired length,
which is made of any desired thickness from 3 mm. upwards, according to the
purpose for which it is designed to be used and is adapted for use as a material
for preventing the passage of heat.
Having now particularly described and ascertained the nature of the soid inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Sheet material consisting of a more or less thick layer of stalks of straw
seagrass, pampas-grass, or the like, which is covered on one side or both sides
with woven fabric and is pressed and sewn jointly with the latter.
2. The hereinabove described improved sheet-material adapted for use as a
non-conductor of heat and consisting of stalks of material of the kind mentioned
and woven fabric arranged and united together as hereinbefore described.
