An Improved Manufacture of Pile Fabrics.
I, PAUL MUTHMANN, of Elberfeld, Rhenish Prussia, in the Empire of 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 pile fabrics and particularly to the
manufacture of 'mohair velvets on double-pile looms in a cheaper and easier manner
than has been practised hitherto.
Heretofore such velvets of a strong and saleable kind could only be produced on.
double pile looms by placing the tuft of pile (bound into the ground by a single
pick of weft) between two sets of ground-warps to keep it upright. In fabrics
manufactured in this manner both sets of ground-warps are bound exactly alike and
between them a special warp is applied which floats over the backs of the tufts of
pile to prevent the said tufts from being pushed out.
According to my invention, while I bind the pile tufts into the ground by single
picks of weft, I dispense with the floating warp at the back of the fabric. In order
that my invention may be more readily understood, I will describe the same with
reference to the accompanying drawings of which
Figure 1 is a section through the fabric parallel with the ground-warp threads,.

my invention.
In each of these figures A designates the pile warp, B, B the threads of the
ground-warp that bind the pile warp, C, C the intermediate threads of the ground.
warp, and D, E, F, G, the weft threads.
The warp threads B and C in both fabrics are woven with the weft in the usual.
manner to form a plain cloth, but at the same time the pile warp A is woven
alternately into the upper and lower fabric at each fourth pick, and is bound by
passing between the warp threads B and the weft.
It
The fabric seen from the back as in Figure 3 resembles a plainly woven taffeta,
while the tufts of pile are covered at the back and secured firmly in the ground.
and are thus prevented from being pushed out, the resulting cloth being strong and
durable. The black squares in Figure 3 denote the places where the pile warps
are locked into the ground; the pile tufts are of course not visible from the back
of the fabric. The pile warp is cut in the usual, or in any suitable manner.
is clear that if the warp threads B were omitted the product obtained would
not be a woven fabric and hence my improved pile fabric differs essentially from.
those fabrics in which a floating warp is used to bind the pile tufts into the ground
warp. I do not confine myself to binding the tufts by every fourth pick as above
described as I may arrange to bind the tufts at lesser or greater intervals.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I.
claim is:
1 A double nile fabric having a plain woven ground in which each pile tuft is
