Improvements in the Manufacture of Double Pile Fabrics:
I, OTTO HALLENSLEBEN, of Hilden, in the Province of the Rhine, German
Empire, Engineer, 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 pertains to the manufacture of double pile fabrics, in which two
fabrics are woven face to face and the pile warp threads tied, not only by the
ground web, but also by a second web, which engages the pile.
Hitherto in the bindings for pile fabrics in which cover warp threads, and
threads engaging the pile were employed, a disadvantage has become manifest that
the tufts of pile could be withdrawn or pulled out of the finished fabric.
The object of my invention is to obviate the above by causing the tufts of pile
to be secured against withdrawal or pushing out of the back and also to attain that
the plush fabric shall always maintain its upright position.
According to my invention in the formation of double pile fabrics of the said
kind, I employ a ground web and also a second web to engage or bind the tufts of
pile. Especially, when employing a pile binding in which each pick or thread of
weft carries pile, it is possible in the case of coarse fabrics (such as Carpets, plushes
etc.), to easily pull out the separate tufts of pile out of the fabric, and the bindings
now in use to counteract this objection have not entirely answered the purpose.
In the present invention, by employing a special binding or tying web, I obviate
not only this objection, but by the special arrangement of this particular web over
the ground-web, the tufts of pile assume an upright position of a durable character.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar leters denote similar parts throughout the several views, and in
which:
Figures 1 & 2 show the binkling of fabric of this description, of which Figure 1
is a longitudinal section through the fabric, and Figure 2 a horizontal section
through the tufts of pile, as shown in Figure 1.
ee designate the ground weft-threads of the ground web, of which every thread
carries pile; bb¹ are the binder warps or threads of the ground web the threads of
which bind crosswise one over and one under each weft-thread. With this ground-
web the new binding or tying web forming the characteristic feature of my inven-
tion is connected, by means of the chain c arranged above the same, said binding
or tying web being formed by or consisting of the ground weft threads f and the
ground warp-threads a a¹.
The tufts of pile d, which are held by means of the ground weft-threads e of the
ground web, are held or secured between two adjacent ground weft threads e of
the ground web, and in this manner the pulling out of the pile-threads is rendered
impossible, and at the same time the tufts of pile are so tied, that the same are
caused to receive and maintain a perfectly upright position. It should also be
remarked that the said second binding web, above the pile tufts, is more closely
woven than the ground web.
In the drawing a taffet-binding, i.e. a binding where every single thread binds

page_text: crosswise, one under, and one over each pick or thread of weft, is used for the new
binding or tying web, said taffet binding being more especially suitable for binding
the weft threads. I wish it however to be understood that I could employ any
other suitable binding for this purpose.
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
A binding for pile fabrics, characterised by the tufts of pile being tied, not only
by the ground web, but also, by a binding or tying web, arranged above the ground
web, said binding web being connected or tied to the ground web, by means of
warp threads, in the manner as described.
