Improvements in Double Pile Fabrics Woven Face to Face.
We, JOSÉ REIXACH, a Managing Director, of Lister & Co., Ld., of Manningham
Mills, Bradford, in the County of York, and HERBERT SCOTT, Manufacturer's
Assistant, of the same address, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to improve the manufacture of double pile fabrics
woven face to face by reducing the number of picks to give the required number
of pile tufts and so cheapen the cost of production and at the same time to
produce a cloth in which the pile tufts are distributed evenly over the face and
held firmly by the warp and weft threads and in which the top and bottom pieces.
are made exactly alike. The invention is specially applicable to those fabrics in
which a strong fibre such as mohair is employed.
The pile warp is placed on five separate shafts each working independently
of the other, called hereafter 1, 2, 3, 4 and 5, each of which is tied into the
ground of both top and bottom pieces by three picks of weft, two picks of weft
without pile intervening before the pile thread is again tied in. Heretofore in
this class of pile fabric woven face to face it has been necessary to allow three
picks of weft without pile to intervene between each pile tuft in the same dent
or reed, but by employing five shafts or healds of pile according to the present
invention an equal distribution of the pile and a saving in the cost of production
is effected with the use of only two picks of weft without pile,
This may be effected by weaving in the following order:
The 1st pick No. 1 and No. 2 pile threads are passed to the back, and No. 4.
to the face of the pick thrown in the top piece.
The 2nd pick-Nos. 2 and 3 pile threads are passed to the back and No. 5 to the
face of the pick thrown in the bottom piece.
The 3rd pick-Nos. 3 and 4. pile threads are passed to the back, and No. 1 to the
face of the pick thrown in the top piece.
The 4th pick Nos. 4 and 5 pile threads are passed to the back, and No. 2 to the
face of the pick thrown in the bottom piece.
The 5th pick-Nos. 1 and 5 pile threads are passed to the back, and No. 3 to the
face of the pick thrown in the top piece.
The 6th pick-Nos. 1 and 2 pile threads are passed to the back, and No. 4 to the
face of the pick thrown in the bottom piece.
The 7th pick-Nos. 2 and 3 pile threads are passed to the back, and No. 5 to the
face of the pick thrown in the top piece.
The 8th pick-Nos. 3 and 4 pile threads are passed to the back, and No. 1 to the
face of the pick thrown in the bottom piece.

page_text: The 9th pick- Nos. 4 and 5 pile threads are passed to the back, and No. 2 to the
face of the pick thrown in the top piece.
The 10th pick-Nos. 1 and 5 pile threads are passed to the back, and No. 3 to the
face of the pick thrown in the bottom piece.
If desired the order of tyeing in the pile threads may be varied, thus No. 3 may
be tied in next to No. 1, and No. 5 next to No. 3, and so on.
This completes the cycle of picks and No. 1 now follows:-
The ground warps may be either single i.e. one warp in each piece for each pile
thread, or they may be double i.e. one warp on either side of each pile thread; they
are tied in to float on the face for two picks then on the back for 1 pick, then
on the face for 1 pick and then on the back for pick and they are so tied in
that the warps on either side of each pile thread work oppositely to that pile
thread; where double warp threads are employed they are both worked together
oppositely to the pile for the three picks by which the pile is tied in to the ground,
for the two intervening picks, which carry no pile, these two warp threads work
oppositely to each other one passing over and the other passing under each pick
of weft; by this means by the frequent crossing of the warp threads a saving of
weft is effected and a firmer ground is obtained than is the case when both warp
threads are worked together throughout.
If so desired the ground warps may be floated over three then under two picks
or over 4 and under 1 or in any other suitable
way.

warps may be tied in and Figures 2 and 3 diagram views of the face of two
cloths Figure 2 shewing a cloth in which a single ground warp is used for each
pile thread and Figure 3 shewing a cloth in which a pair of ground warps is used
for each pile thread.

Figure 1 of the drawings lodged with our Provisional Specification is a diagram
view of one example showing the order in which the pile warps may be tied in,
and Figures 2 and diagram views of the face of two cloths-Figure 2 showing a
cloth in which a single ground warp is used for each pile thread, and Figure 3
showing a cloth in which a pair of ground warps is used for each pile thread.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is:
1. Double pile fabrics woven face to face having the pile warps in five sets or
one piece by
divisions each of which is tied first into the ground of
three picks and then by three picks into the other piece and with two picks
of weft without pile intervening between one set of three picks in each ground and
the next set of three picks substantially as herein before described and illustrated
in Figure 1.

illustrated in Figure 2.
3. Double pile fabrics woven substantially as herein before described and
illustrated in Figure 3.
