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 into the ground part of each of the two fabrics alternately and after-
wards 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
each of two pile-fabrics woven face to face may be securely held in the fabric
when such fabrics are separated and during the subsequent dyeing and other
finishing processes and in the use and wear of such fabric and to ensure that the
pile-tufts shall project or issue vertically from the ground portions of the fabrics
and without any tendency to lean to either side.
According to my invention in weaving pile-fabrics face to face I employ in
each fabric two or more ground-warp-threads for each pile-warp-thread and
employ for each row of pile-tufis extending across the fabric besides the weft-
thread with which the pile-warp is engaged two or more weft-threads which do
not carry pile and I cause the ground-warp-threads and weft-threads to be so
interwoven that the pile-less wefts which are inserted before and after the wefts
which carry pile are made to float on the back of the fabric at the places where
the pile-tufts are formed so as to prevent the pile-tufts from being pushed out
backwards from the fabric and so that at each place where a pile-tuft projects
from the face of the fabric there shall be on each side of such pile-tuft a ground-
warp-thread or ground warp-threads on the face to nip the pile-tuft equally from
both sides so as to give it a vertical position and retain it in such vertical position.
My invention may be carried into effect in different ways but by way of
illustration I will describe one way of producing a fabric according to my
invention. In this way of producing a fabric I arrange that for each row of
pile-tufts extending across each of the two fabrics woven face to face three weft-
threads are employed and the middle one is caused to carry the pile-tufts and
pass over two ground-warp-threads and under two ground-warp-threads alter-
nately, and the other two weft-threads which do not carry pile are as seen from
the back of either fabric made to pass alternately under one ground-warp-thread
and over three ground-warp-threads and the ground-warp-threads are each made
to pass on the back of the cloth over two weft-threads and then on the face of
the cloth over four weft-threads, in such a way that whereas the ground-warp-
thread on one side of a pile-tuft passes over the pile-carrying weft, the two pre-
ceding wefts and one succeeding weft. the ground-warp-thread on the other side
of such pile-tuft passes over the pile-carrying weft. the one preceding weft and
two succeeding wefts. The result of this arrangement is that around each pile-

page_text: tuft the ground-warp-threads and the weft-threads which do not carry pile form
a tabby weave, and the pile-tuft is firmly supported on all sides and covered on
the back by the weft-threads which do not carry pile.

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 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 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 into the ground part of each of the two fabrics alternately and after-
wards 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
each of two pile-fabrics woven face to face may be securely held in the fabric
when such fabrics are separated and during the subsequent dyeing and other
finishing processes and in the use and wear of such fabrics and to ensure that the
pile-tufts shall project or issue vertically from the ground portions of the fabrics
and without any tendency to lean to either side.
According to my invention in weaving pile-fabrics face to face employ in
each fabric two or more ground-warp-threads for each pile-warp-thread and
employ for each row of pile-tufts extending across the fabric, besides the weft-
thread with which the pile-warp is engaged two or more weft-threads which do
not carry pile and I cause the ground-warp-threads and weft-threads to be so
interwoven that the pile-less wefts which are inserted before and after the wefts
which carry pile are made to pass to the face of the cloth and also made to float
on the back of the fabric at the places where the pile-tufis are formed so as to
prevent the pile-tufts from being pushed out backwards from the fabric and so
that at each place where a pile-tuft projects from the face of the fabric there
shall be on each side of such pile-tuft a ground-warp-thread or ground-warp-
threads on the face to nip the pile-tuft equally from both sides so as to give it
a vertical position and retain it in such vertical position. ·
My invention may be carried into effect in different ways but by way of
illustration will describe one way of producing a fabric according to my
invention. In this way of producing a fabric I arrange that for each row of
pile-tufts extending across each of the two fabrics woven face to face three weft-
threads are employed and the middle one is caused to carry the pile-tufts and
pass over two ground-warp-threads and under two ground-warp-threads alier-
nately, and the other two weft-threads which do not carry pile are as seen from
the back of either fabric made to pass alternately under one ground-warp-thread
so as to pass to the face of the fabric and over three ground-warp-threads on the
back of the fabric and the ground-warp-threads are each made to pass on the
back of the cloth over two weft-threads and then on the face of the cloth over
four weft-threads, in such a way that whereas the ground-warp-thread on one
side of a pile-tuft passes over the pile-carrying weft, the two preceding wefts and

page_text: one succeeding weft, the ground-warp-thread on the other side of such pile-tuft
passes over the pile-carrying weft, the one preceding weft and two succeeding
wefts. The result of this arrangement is that around each pile-tuft the ground-
warp-threads and the weft-threads which do not carry pile form a tabby weave,
and the pile-tuft is firmly supported on all sides and covered on the back by the
weft-threads which do not carry pile.
In the accompanying drawing, Fig. 1 is a longitudinal diagrammatic section
through a portion of each of two fabrics woven face to face according to the
above described way of producing a fabric according to my invention. Fig. 2
is a diagrammatic plan or back view of the upper of the two fabrics shown in
section in Fig. 1 and Fig. 3 is a diagrammatic horizontal section taken on the
plane indicated by the line A A of Fig. 1 and showing the face or pile-covered
surface of the lower of the two fabrics shown in Fig. 1. In these figures a a
represent the ground-warp-threads and bb represent the weft-threads around
which the pile-warp-threads or pile-tufts are passed or held, 6b and be repre-
sent the weft-threads which are not engaged with or embraced by the pile-warp-
threads or pile-tufts and c c represent the pile-warp-threads in Fig. 1 and the
pile-tufts in Figs. 2 and 3.
From these figures it is obvious that in the fabrics which are illustrated in
such figures there are in each of the two fabrics woven together, two ground-
warp-threads a al for each pile-warp-thread c and two pile-less wefts for
each weft b which carries pile and that the ground-warp-threads and weft-
threads and are so interwoven that the pile-less wefts which are
inserted before and after the wefts which carry pile, are made to float on the
back of the fabric at the places where the pile-tufts e are formed and to pass
to the face of the fabric at intermediate points and so that at each place where
a pile-tufte projects from the face of the fabric there is on each side of such
pile-tuft a ground-warp-thread a or ' on the face of the fabric to nip the pile-
tuft c equally from both sides so as to give it a vertical position and retain it
in such vertical position. It is also obvious from the said figures that of the
three weft-threads & employed for each row of pile-tufts e extending across
each of the two fabrics woven face to face, the middle one carries the pile-
tufts and passes over two ground-warp-threads a, a and under two ground-
warp-threads a alternately and the other two wefts 3 which do not carry
pile are made to pass alternately over one ground-warp-thread on the face of
the fabric in which they are employed and under three ground-warp-threads at
the back of such fabric and the ground-warp-threads a are each made to pass
on the back of the cloth over two weft-threads and then on the face of the cloth
over four weft-threads in such a way that whereas the ground-warp-thread on
one side of a pile-tuft c passes over the pile-carrying weft b, the two preceding
wefts and one succeeding weft ; the ground-warp-thread a¹ on the other
side of such pile-tuft e passes over the pile-carrying weft b. the one preceding
weft and two succeeding wefts bb. It is obvious from the said figures that
from the above described arrangement of the ground-warp-threads and weft-
threads it results that around each pile-tuft the ground-warp-threads and the
weft-threads which do not carry pile form a tabby weave. The result of the
coaction of the ground-warp-threads and weft-threads in the said arrangement
is that each pile-tuft c is firmly supported from all sides and covered on the back
by the weft-threads which do not carry pile, although the fabric is formed all
in one layer or system of crossings of warp and weft.
It is also obvious from the accompanying drawing that the two fabrics woven
together are alike in structure.
By arranging in the manner herein before described those weft-threads which
do not carry pile I ensure that the pile-tufts of each of the two pile-fabrics
woven face to face may be securely held in the fabric when such fabrics are
separated and during the subsequent dyeing and other finishing processes and
in the use and wear of such fabric and by arranging the ground-warp-threads

page_text: in the manner bereinbefore described I ensure that the pile-tufts shall project
or issue vertically from the ground portions of the fabrics and without any
tendency to lean to either side.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is
.
1. A mohair-plush of the kind in the manufacture of which two fabrics are
woven face to face and the pile-warp-threads are tied by single picks of weft
into the ground parts of the two fabrics alternately and afterwards the pile-
warp-threads are cut between the two fabrics so that the said fabrics are separ-
ated from each other, and in which are employed for each pile-warp-thread
two or more ground-warp-threads and for each row of pile-tufts extending across
the fabric a weft-thread which carries the pile-tufts and two or more weft-
threads which do not carry pile, the pile-less wefts being inserted before and
after the pile-carrying wefi-threads and made to float on the back of the fabric
at the places where the pile-tufts are formed and passing to the face of the
fabric at intermediate points and the ground-warp-threads being so disposed
that at each place where a pile-tuft projects from the face of the fabric there
is or are on each side of such pile-tuft a ground-warp-thread or ground-warp-
threads on the face of the fabric to nip the pile-tufi equally from both sides
substantially as hereinbefore described.
2. A mohair-plush of the kind in the manufacture of which two fabrics are
woven face to face and the pile-warp-threads are tied by single picks of weft
into the ground-parts of the two fabrics alternately and afterwards the pile-
warp-threads are cut between the two fabrics so that such fabrics are separated
from each other and there are employed for each pile-warp-thread two ground-
warp-threads and for each row of pile-tufts extending across the fabric a weft-
thread which carries the pile and two weft-threads which do not carry pile. the
weft-thrend which carries the pile being caused to pass alternately over two-
ground-warp-threads and under two ground-warp-threads, the pile-less wefts being
made to pass alternately over one ground-warp-thread on the face of the fabric
and under three ground-warp-threads on the back of the fabric and the ground-
warp-threads being made to pass on the back of the cloth over two weft-threads
and then on the face of the cloth over four weft-threads in such a way that
whereas the ground-warp-thread on one side of a pile-tuft passes over the pile-
carrying weft, the two preceding wefts and one succeeding weft, the ground
warp-thread on the other side of such pile-tuft passes over the pile-carrying
weft, the one preceding weft and two succeeding wefts, substantially as and
for the purposes herein before described.
