PROVISIONAL SPECIFICATION.
A New or Improved Method of Manufacturing certain Pile Fabrics.
1, WILLIAM RIGG, of 26, Swaine Street, Bradford in the County of York,
Designer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved method of manufacturing double
faced pile fabrics that is fabrics having pile on each side and its object is to
enable this class of fabric to be woven in the ordinary loom for weaving single
faced pile fabrics.
For this purpose I weave the fabrics in the ordinary way with the pile on one
side only but at the back of the fabric or fabrics I introduce what I herein-
after term "pile drawing threads" running along the back through each loop of
the pile. These pile drawing threads may be either warp or weft threads and
with the exception of passing through the pile loops at the back are not otherwise
interwoven with the body of the fabric.
The pile is so interwoven with the body of the fabric and the pile drawing
threads passed through the pile in such a manner that after the pile is cut the act
of separating the pile drawing threads from the fabric pulls one limb of each pile
loop through the fabric causing it to project at the back in a similar manner to
the other limb at the front and thus forms a pile face at the back.
Instead of passing the whole of the pile loops round the pile drawing threads
only such of the loops as would be required to produce any desired pattern may
be passed round such threads. And the whole or a portion of the pile passed
round said threads may be drawn from the front to the back of the fabric.

COMPLETE SPECIFICATION.
A New or Improved Method of Manufacturing certain Pile Fabrics.
I, WILLIAM RIGG, of 26, Swaine Street, Bradford, in the County of York,
Designer, 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 :-
This invention relates to a new or improved method of manufacturing double
faced pile fabrics that is fabrics having pile on each side and its object is to enable
this class of fabric to be woven in the ordinary loom for weaving single faced pile
fabrics.
For this purpose I weave the fabrics in the ordinary way with the pile on one
side only but at the back of the fabric or fabrics 1 introduce what I hereinafter
term "pile drawing threads" running along the back through each loop of the
pile. These pile drawing threads may be either warp or weft threads and with the
exception of passing through the pile loops at the back are not otherwise inter-
woven with the body of the fabric.
The pile is interwoven with the body of the fabric so as to produce what is
known as a fast pile and the pile drawing threads are passed through the pile
loops at the back of the fabric in such a manner that after the pile is cut the act
of separating the pile drawing thread from the fabric pulls one limb of each pile
loop through the fabric causing it to project at the back in a similar manner to
the other limb at the front and thus forms a pile face at the back.

Instead of passing the whole of the pile loops round the pile drawing threads
only such of the loops as would be required to produce any desired pattern may be
passed round such threads.
In fabrics in which the pile is formed by the weft the pile drawing threads run
parallel with the warp and when the pile is formed by the warp as in what are
known as double pile fabrics the pile drawing threads are parallel with the weft
and may be introduced by a separate or independent shuttle by means of an
ordinary circular shuttle box or drop box arrangement.
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:
A double faced pile fabric formed by drawing a portion of the pile on one
face through the fabric so as to project on the other face by means of a thread
introduced for that purpose during the weaving process, substantially as herein
shown and described.
