Improvements in the Manufacture of Plush and similar
Pile Fabrics.
We, HERMANN MÜLLERS and ARTHUR SPINDLER both of Dülken in the
Kingdom of Prussia and German Empire, 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 :-
In order to obtain two similar fabrics when weaving two pieces of plush face to
face, it is customary to put two pile warp threads in each dent of the reed. This
requirement involves the use of strong well twisted yarn, because otherwise the
ends frequently break owing to the considerable friction between them.
The object of this invention is to obviate this disadvantage and at the same time
to enable a smoother and more regular product to be obtained.
We will describe our present improvements with reference to the accompanying
drawings in which :-
Figure 1 represents a short longitudinal section of the finished plush as ordinarily
woven
Figure 2 represents one form of our improved weave;
Figure 3 another modification of the improved weave; and,
Figure 4 a longitudinal section of the finished fabric shewn in Figure 3 and in
the upper part of Figure 2.
According to these improvements we employ a special method of binding the
pile threads into the back and by this means we are enabled to use one warp end
only in each dent and to obtain two textures in each of which the pile is fast and
regular.
Our method consists in taking every third pick on one or on both fabrics under the
pile warp threads on the inner face or faces as shewn in the upper part of Figure 2
and in both of the fabrics shewn in Figure 3. These picks are not bound by the
back warp ends and lie upon the face of the fabric as represented by Figure 4.
These binding picks secure the pile firmly and we prefer to employ them in each
of the fabrics as shewn by Figure 3.
In proceeding as represented by Figure 2 there are ten picks to the round, of
which the 4th and 9th are binding picks in the upper fabric; the other picks being
divided between the upper and the lower cloths. As represented by Figure 3
there are twelve picks to the round of which the 2nd and the Sth are binding picks
for the upper, and the 5th and 11th for the lower fabrics. The remaining picks
are back picks divided between the two fabrics as indicated.
The back warp ends are indicated in dotted lines only, in the upper part of
Figure 2 and in Figure 3; elsewhere they are not indicated for the sake of
obtaining greater_clearness.
Where the threads are represented, a bindicate the back warp ends; and ef the
pile warp ends. The picks of weft are consecutively numbered.
The fabric may be woven on a double velvet or similar loom, and is afterwards
cut and finished in the well known manner.
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. The hereinbefore described method of manufacturing plush, substantially as
set forth and as illustrated by the accompanying drawings.
2. As a new article of manufacture, plush and similar pile fabrics woven face to

page_text: face and having the 'pile threads bound upon the back by every third pick of the
weft substantially as hereinbefore described with reference to the accompanying
drawings.
