Improvements in the Method employed in the Manufacture of
Plush, Carpets, and other Pile Fabrics.
We, HERMANN MÜLLERS, of 34 Süchtelnerstrasse, and ARTHUR DIETRICHE
SPINDLER, of 19 Viersenerstrasse, both of Dülken, Prussia, in the Empire of
Germany, Plush 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:-
The employment of pile wires in the manufacture of plush, carpets and other-
pile fabrics in power looms, necessitates a comparatively slow speed loom, as the
insertion of the wires has to be effected very carefully and consequently slowly,
whilst on the other hand a certain power is required to pull them out again from
the woven fabric. Moreover, in lcoms in which pile wires are employed, the width
of the fabric produced is limited, as for greater widths than those hitherto.
produced in such looms, the wires would be too long to be workable, and for
the same reason it is impossible to produce several pieces side by side in the same
loom.
According to the present invention, we dispense with the pile wires and use.
supplementary or additional weft threads which are stretched and kept in position
by a supplementary or additional warp. A loom worked by this method produces.
a much larger output than a loom working with pile wires.
Our invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is an enlarged section showing a plush weaving produced by the use of
supplementary or additional wefts.
Fig. 2 is an enlarged section showing a carpet weaving produced by the use of
supplementary or additional wefts.
Fig. 3 is an enlarged section showing a tabby or taffetas weaving in which the-
supplementary or additional wefts are bound by supplementary or additional warps,.
and
Fig. 4 represents in section parts of a loom showing a diagram of the process of
weaving.
As will be seen from the various illustrations, the supplementary or additional.
wefts are always above the supplementary or additional warps, or are supported by
them, and the pile passes over and binds in the well stretched supplementary or
additional weft, thereby forming loops similar to when pile wires are used.
The supplementary or additional wefts are generally removed during the process.
of weaving by thirty to forty at a time, which can be done without any great
trouble, and in this case the supplementary or additional warp is also removed from
the fabric by winding it off on to a separate beam as shown in Fig. 4.
In carpets the supplementary or additional weft threads may be simply left in
the fabric as the pile is close enough to cover them and conceal them from view..
In this case however it is preferable to replace the supplementary or additional
straight warp shown in Fig. 2 by that shown in Fig. 3 for tabby or taffetas weaving ;.
or any other suitable binding or interweaving may be employed.
If it is desired to produce brocaded or broché plush by the above method, it will
be necessary to bring only those pile threads which appear in the brocade or broché
figure to the surface around the supplementary or additional wefts.
The formation of the ground-work is in every case similar to that commonly in
use for each particular class of goods.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
--
1. A method of manufacturing plush, carpets and other pile fabrics in power
looms, by forming the pile by the aid of supplementary or additional weft threads
supported and stretched by supplementary or additional warp threads passed
between the ground-work and the supplementary or additional weft threads, both
of which threads are withdrawn during the process of weaving after the pile has
been formed over the weft threads, substantially as herein shown and described
with respect to Figs. 1, 2 and 4.
2. A method of manufacturing plush, carpets and other pile fabrics in power
looms, by forming the pile by the aid of supplementary or additional weft threads
supported and stretched by supplementary or additional warp threads, both of
which threads are left in the finished fabric, and for such purpose, instead of the
supplementary or additional weft threads being simply carried by the supple-
mentary or additional warp threads, they are bound in by the latter by a tabby or
taffetas or other suitable weaving, substantially as herein shown and described with
respect to Fig. 3.
