Improvements in the Manufacture of Pile Fabrics.
I, JOSÉ REIXACH, of Manningham Mills, Bradford, in the County of York,
Managing Director, 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 pile fabrics woven face to face and is specially
applicable to those fabrics in which a strong fibre such as mohair is employed to
form the pile.
Hitherto, attempts to weave these fibres face to face in the ordinary well known
methods have failed to produce a marketable cloth owing to the uneven appear-
ance of the pile when woven.
The object of this invention is mainly to produce an even surface by employing
a single pile thread in each dent or split instead of two threads which in the
ordinary, weaves cross each other and so produce the fault referred to.
I throw three picks of weft in one piece then two in the other piece and so on,
so that in the woven double cloth there are three picks of weft woven into one,
piece for every two woven into the other piece; the order of throwing these picks
may be altered as desired.
In each dent of the reed I employ for one piece that in which three consecutive
picks of weft are thrown which may be by preference the bottom piece two warps
preferably of different thicknesses woven off separate.beams; each pile thread has
a thick warp thread on one side of it and a thin warp thread on the other side.
The top piece has either single or double warps as desired and the warp threads
are crossed and the pile threads tied in to the ground of this piece as in the
Utrecht wire loom weave. There are two pile. warps weaving alternately in
the top and bottom pieces and crossing from one piece to the other. Assuming the
three pick piece to be woven as the bottom piece and the two pick or Utrecht
I first throw a
piece to be woven on the top the double piece is woven as follows.
pick of weft in the bottom piece so that the first pile thread is wrapped round it
half the thick ground warp threads being raised and half depressed and the thin
warp threads all being raised; the second pick is thrown in the same piece the
first pile thread being now raised and the thick warp threads being crossed those
threads which were raised for the previous pick being now depressed and vice versa
half the thin warp threads are also depressed for this pick. The third pick is also
thrown in the same piece the first pile thread being again depressed and wrapped
round this pick, all the thick warp threads are raised and the same thin warp
threads are depressed which were depressed for the previous pick, this third pick
of weft is thus bound to the ground only by the pile and the thin warp threads.
The first pile thread is now crossed over to the top piece and is bound in to it by
the fourth pick of weft half the warp threads of the top piece being raised and half
depressed. The second pile thread is now tied in to the ground of the top piece
by the fifth pick; both pile and warp threads being crossed, those warp threads
which were raised for the previous pick being now depressed and vice versa and the
second pile thread being raised and the first pile thread depressed.
The second pile thread is now crossed over to the bottom piece and is tied into
that piece by the three following picks in the same way as the first pile thread was
tied in by the 1st 2nd and 3rd picks except that the alternate or opposite warp
threads are now raised and depressed as the 6th 7th and 8th picks are thrown.

page_text: The second pile thread is now crossed over to the top piece and tied in to the
ground of that piece by the 9th pick, the same warp threads being raised and
depressed as at the 5th pick which was the last pick thrown in the top piece.
The pile and warp threads are now crossed and the 10th and last pick is thrown
in the top piece the first pile thread being raised and the second depressed. There
are ten picks to the round or repeat of the tappets so that the 1st, 2nd, 3rd picks
now follow and so on.
It will be seen that each pile thread is tied into one piece by four picks, passing
round one pick then floating on the face of the cloth over two picks then passing
round one pick, and each pile thread is tied into the opposite piece by three picks,
passing round the back of the first round the face of the second and round the
back of the third pick.
In this way when the two pieces are cut asunder afterwards in the usual manner
two fabrics are produced of different construction but with an even surface of pile
on both owing to the same pile thread being used to form the same row or line of
tufts of pile instead of two different pile threads forming such row and crossing
each other as. is usual when two pile fabrics are woven face to face. In a
modification the position of the two pieces is reversed and the two pick or Utrecht
piece is woven as the bottom piece and the 3-pick-piece is woven on the top. In
this case the first three picks of weft are thrown in the top piece the 4th and 5th
are thrown in the bottom piece, the 6th 7th and 8th in the top piece and the 9th
and 10th in the bottom piece and so on.
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. The combination weave described of double pile fabric woven face to face
with the pile threads tied into one piece by four picks of weft; and tied into the
other piece by three picks of weft two enclosed by the ground warps and one
outside the ground warps.
2. The combination weave described of double pile fabric woven face to face in
which the warps of the two pick or Utrecht cloth may be on both sides of the pile
or on one side only and the warps of the 3-pick weave are on both sides of the pile.
