PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Mohair-plushes Woven
Face to Face,
I, WALTER KÜPPER, of Dülken, Germany, Manufacturer, do hereby declare
the nature of this invention to be as follows::
_
My invention relates to the manufacture of mohair-plushes in which two
fabrics are woven face to face and the pile-warp-threads are tied by single
picks of weft alternately into the ground part of each of the two fabrics and
afterwards the pile-warp-threads are cut between the two fabrics so that the
said fabrics are separated from each other.
The object of my invention is to provide means by which the pile-tufts of
pile-fabrics woven face to face may be securely held in each fabric when such
fabrics are separated and during the subsequent dyeing and other finishing
processes and in the use and wear of such fabrics.
According to my invention in weaving pile-fabrics face to face, I combine
with each ground-fabric, wefts which are made to pass and lie behind the backs
of the pile-tufts and I cause such wefts to be themselves held in or upon the
ground-fabrics either by being interwoven with the ground-warp-threads or by
being interwoven with warp-threads which are provided to hold such wefts and
have the wefts of the ground-fabrics also interwoven with them.
The wefts which are employed according to my invention to pass and lie
behind the pile-tufts may be combined with any structure of ground-fabric
which may be employed in pile-fabrics woven face to face in which the pile-
warp-threads are tied into the ground-parts of the fabrics by single picks of
weft. One weft or two or more wefts may he caused to pass and lie behind each
row of pile-tufts extending across each of two pile-fabrics woven face to face.
In one way of producing a fabric which I describe by way of illustration of
my invention each pile-tuft in each of two fabrics woven face to face may be
held on the face of the fabric between two ground-warp-threads and some of
the ground-warp-threads may have only interwoven with them the wefts upon
or around which the pile-tufts are secured while the rest of the ground-warp
threads have interwoven with them both the wefts upon or around which the
pile-tufts are secured and the wefts which are to pass and lie behind the pile-
tufts.
In a second way of producing a fabric which I describe by way of illustra-
tion of my invention each pile-tuft in each of two fabrics woven face to face
may be held on the face of the fabric between two ground-warp-threads, and
warp-threads to hold to the ground-fabric the wefts which are to pass and lie
behind the pile-tufts may be made to pass or lie at the sides of the pairs of
ground-warp-threads aforesaid and have interwoven with them the wefts upon
or around which the pile-tufts are secured and the wefts which are to pass or
lie hehind the pile-tufts.

Face to Face.
I, WALTER KÜPPER, of Dülken, Germany, 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 state-
ment:-
My invention relates to the manufacture of mohair-plushes in which two
fabrica are woven face to face and the pile-warp-threads are tied by single
picks of weft alternately into the ground part of each of the two fabrics and
afterwards the pile-warp-threads are cut between the two fabrics so that the
said fabrics are separated from each other.
The object of my invention is to provide means by which the pile-tufts off
pile-fabrics woven face to face may be securely held in each fabric when such
fabrics are separated and during the subsequent dyeing and other finishing
processes and in the use and wear of such fabrica.
According to my invention in weaving pile-fabrics face to face, I combine
with each ground-fabric, wefts made to pass and lie behind the backs of the
pile-tufts without ever passing on the face of the fabric and I cause such wefts
to be themselves held in or upon the ground-fabrics either by being interwoven
with the ground-warp-threads or by being interwoven with warp-threads which
are provided to hold such wefts and have the wefts of the ground-fabrics also
interwoven with them.
The wefts which are employed according to my invention to pass and lie
behind the pile-tufts and are kept from passing on to the faces of the fabrics
in which they are employed may he combined with any structure of ground-
fabric which may be employed in pile-fabrics woven face to face in which the
pile-warp-threads are tied into the ground parts of the fabrics by single picks
of weft.
In conjunction with each row of pile-tufts extending across each of two
pile-fabrics woven face to face there may be employed one weft or two or more
wefts to pass and lie behind the pile tufts without passing on the face of the
cloth.
In one way of producing a fabric which I describe by way of illustration of
my invention each pile-tuft in each of two fabrics woven face to face may be
held on the face of the fabric between two ground-warp-threads and some of
the ground-warp-threads may have only interwoven with them the wefts upon
or around which the pile-tufts are secured while the rest of the ground-warp
threads have interwoven with them both the wefts upon or around which the
pile-tufts are secured and the wefts which are to pass and lie behind the pile-
tufts without being made to pass on the face of the fabric.
One form of cloth made in this way of producing a fabric according to my
invention is illustrated by Figs. 1 and 2 of the accompanying drawings, Fig. 1
being a diagrammatic face-view or plan showing the pile-surface of one of the
two cloths woven face to face and Fig. 2 being a longitudinal section taken on
the plane indicated by the line A A of Fig. 1 through the cloth illustrated
in such figure. In Figs. 1 and 2 are the wefts on or around which the
pile-tufts 6 are secured and c c are the wefts which are made to pass and lie
behind the backs of the pile-tufts without passing on the face of the fabrics
and 2 and 4 are the ground-warp-threads which have interwoven with them
only the wefts a upon or around which the pile-tufts are secured and 1 and 3
are the ground-warp-threads which have interwoven with them both the wefts a,

page_text: and the wefts c. In Fig. 1 it is clearly shown that on the face of each of the
two fabrics woven face to face each of the pile-tufts is held between two
ground-warp-threads so as to be held erect thereby.
It is also shown in Figs. 1 and 2 that in each of the two fabrics woven face
to face the wefts c and the ground-warp-threads 1 and 3 with which they are
interwoven form as it were a fabric on the back of the fabric from which the
pile-tufts & protrude and that in consequence of this the wefts c are held in
position to prevent the pile-tufts 6 from being pushed out backwards from the
fabric from which they protrude.
In order that the wefts c which do not pass on the face of the fabric shown
in Fig. 1 may appear in such figure they are indicated in Fig. 1 as being thicker
than the wefts a although they are ordinarily equal in thickness thereto being
of the same yarn but it is obvious that the wefts a and a may be made of any
relative thickness which may be considered desirable.
In a second way of producing a fabric which I describe by way of illustra-
tion of my invention each pile-tuft in each of two fabrics woven face to face
may he held on the face of the fabric between two ground-warp-threads and
the wefts which are not to pass on the face of the fabric but are to pass and lie
behind the pile-tufts may be secured to the ground-fabric by warp-threads
made to pass or lie at the sides of the pairs of ground-warp-threads aforesaid
and having interwoven with them the wefts upon or around which the pile-
tufts are secured and the wefts which are to pass or lie behind the pile-tufts,
without passing on the face of the fabric.
One form of cloth made in this way of producing a fabric according to my
invention is illustrated by Figs. 3 and 4 of the accompanying drawings, Fig. 3
being a diagrammatic face-view or plau showing the pile-surface of one of the
two cloths woven face to face and Fig. 4 being a longitudinal section taken on
the plane indicated by the line B B of Fig. 8 through the cloth illustrated in
Buch figure. In Figs. 3 and 4 a are the wefts ou or around which the pile-
tufts are secured and are the wefts which do not pass on the faces of the
cloths in which they are employed but are made to pass and lie behind the
backs of the pile-tufts and 1 1 and 33 are the ground-warp-threads which
lave interwoven with them only the wefts a upon or around which the pile-
ufts are secured and 22 and 4 4 are warp-threads which are used to secure
the wefts c to the ground-fabric and have interwoven with them both the wefts a
and the wefts c. In Fig. 3 it is clearly shown that on the face of each of the
two fabrics woven face to face each pile-tuft is held between two ground-
warp-threads 1 1 or 3 3 and so held erect and that the warp-threads 22 and 4 4
to hold to the ground-fabric the wefts e are made to pass and lie at the sides
of the pairs of ground-warp-threads 11 or 3 3.
It is also shown in Figs. 3 and 4 that in each of the two fabrics woven face
to face the wefts and the warp-threads 22 and 4 4 form a kind of fabric on
the back of that from which the pile-tufts & protrude and that consequently the
wefts are held in position to prevent the pile-tufts from being pushed out
backwards from the fabric from which they protrude. In order that the wefts c
may appear in Fig. 3 they are indicated in Fig. 3 as being thicker than the
wefts a although they are ordinarily equal in thickness thereto being of the
same yarn but it is obvious that the wefts and c may be made of any rela-
tive thickness which may be considered desirable.
The provision in mohair-plushes woven face to face of a weft or wefts at
the back of each pile-tuft enables the pile-tufts of such fabrics to be securely
held in such fabrics when the said fabrics are separated and enables such fabrics
to be subjected to dyeing and other finishing processes without risk of the dis-
placement of the pile-tufts and prevents such fabrics from being damaged in
use by the pile-tufts being displaced by pressure applied to the pile-surface of
such fabrics and also permits the adoption of any desired arrangement of the
ground-warp-threads.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In each of two mohair-plushes woven face to face with the pile-warp-
threads tied by single picks of weft into the ground parts of the two fabrics
alternately and afterwards separated by the pile-warp-threads being cut between
the two fabrics the combination with the woft-threads carrying pile-tufts of
other weft-threads which neither carry pile nor pass on the face of the fabric
but are woven so as to pass and lie behind the pile-tufts and are held in or
upon the ground fabric by being interwoven with the ground-warp-threads
substantially as and for the purposes hereinbefore described.
2. In each of two mohair-plushes woven face to face with the pile-warp-
threads tied by single picks of weft into the ground parts of the two fabrica
alternately and afterwards separated by the pile-warp-threads being cut between
the two fabrics the combination with the weft-threads carrying pile-tufts of
other weft-threads which neither carry pile nor pass on the face of the fabric
but are woven so as to pass and lie on the back of the fabric behind the pile-
tufts and are held in or upon the ground-fabric by being interwoven with some
of the ground-warp-threads substantially as and for the purposes herein before
described.
3. In each of two mohair-plushes woven face to face with the pile-warp-
threads tied by single picks of weft into the ground parts of the two fabrics
alternately and afterwards separated by the pile-warp-threads being cut between
the two fabrics, the combination with the weft-threads which carry the pile-
tufts of other weft-threads which neither carry pile nor pass on the face of the
fabric but are so woven as to pass and lie on the back of the fabric behind the
pile-tufts and are held in or upon the ground-fabric by being interwoven with
warp-threads which are provided to hold such weft-threads and have the weft-
threads carrying the pile-tufts also interwoven with them substantially as and
for the purposes herein before described.
