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 to be as
follows:-
:-
This invention relates to double pile fabrics which are woven face to face and
are afterwards cut asunder in the usual manner, the object being to weave such
fabrics with two or more different lengths of pile in the same piece. To effect this
I employ pile threads which cross between the top and bottom pieces and are tied
in to each in any well known manner and in addition I use for each piece separate
auxiliary pile threads which are made to float for a certain number of picks over
the face of the piece according to the length of pile required. These floating pile
threads are to form the longer pile-they are tied into the ground by any desired
number of picks to make a fast tie then floated over the ground for any desired
number of picks then made to pass to the back and floated over the back for a few
picks to form a short float or race at the back then tied into the ground again as
before, and floated for any desired number of picks over the face before being
again passed to the back to form another float or race and so on. Afterwards when
the pile threads which cross from piece to piece have been severed in the usual
manner the short floats of the auxiliary pile threads at the back of each piece are
cut with a knife and the pile threads thus freed are by carding or by other means
brought through to the face of the cloth.
In place of using separate auxiliary pile threads for each piece I cause the
auxiliary pile threads to cross from one piece to another after being floated as
before for any desired number of picks. In this method the auxiliary pile threads.
will be cut by the knife in the loom at the same time as the other pile threads.
Preferably in order to ensure the auxiliary pile threads being cut with a clean
cut by the knife in the loom I cause those threads which have been floating on the
face of one piece for the desired number of picks to make the length of pile required
to be passed round one or more picks in that piece immediately before crossing
them to the other piece.
It will be seen that by this method the threads are presented vertically to the
knife and are thus cleanly cut.

Managing Director, do hereby declare the nature of this invention and in what
mauner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-

auxiliary pile threads which are made to float for a certain number of picks over

hefore and floated. for any desired number of picks over the face before being again
passed to the back to form another float or race and so on. Afterwards when the
pile threads which cross from piece to piece have been severed in the usual manner
the short floats of the auxiliary pile threads at the back of each piece are cut with
a knife and the pile threads thus freed are by carding or by other means brought
through to the face of the cloth.
In place of using separate auxiliary pile threads for each piece I cause the
auxiliary pile threads to cross from one piece to another after being floated as
before for any desired number of picks. In this method the auxiliary pile threads
will be cut by the knife in the loom at the same time as the other pile threads.
Preferably in order to ensure the auxiliary pile threads being cut with a clean
cut by the knife in the loom I cause those threads which have been floating on the
face of one piece for the desired number of picks to make the length of pile
required to be passed round one or more picks in that piece immediately before
crossing them to the other piece.
It will be seen that by this method the threads are presented vertically to the
knife and are thus cleanly cut.
Figures 1, 2, 3 and 4 of the drawings annexed shew diagram views of four
examples of double pile fabrics woven according to my invention.
In Figures 1 and 3 separate auxiliary pile threads are used with each piece-in
Figures 2 and 4 the auxiliary pile threads cross from piece to piece.
In Figure 1, A B, A'B' are the ground warps of the two pieces. CC are the
pile warps which cross from piece to piece and are tied in as shewn or in other well
known manner. DD' are the auxiliary pile threads which are to form the longer
pile they are tied into the ground by any desired number of picks H H to
form a fast tie then floated over the face of the ground for any desired number
of picks F F-then made to pass to the back and floated over the back for a
few picks as shewn at S S¹ then tied into the ground as before and so on.
After the pile threads C C have been severed in the usual manner the short
floats S S of the auxiliary pile threads are as above stated to be cut with a knife
and the threads thus freed are by carding or by other means to be brought to
the face of the cloth.
In Figure 2 the auxiliary pile threads D cross from one piece to the other.
After being tied into one ground by any desired number of picks K to form a fast
tie they are floated over that ground for any desired number of picks E then
before crossing over to the other piece are made to pass round one or more
picks Z in that piece over the face of which they have been floating they are
then directly crossed over and tied into the other piece and made to float over its
face and so on.
In Figures 3 and 4 the warp threads A B A B₁ and the pile threads C are
shewn tied in in another well known manner differing from that shewn in
Figures 1 and 2.
In Figure 3 the auxiliary pile threads D D' after being tied into the ground by
any desired number of picks L L' to form a fast tie are floated over that ground
for any desired number of picks M M¹ then made to pass to the back and floated
over a few picks as shewn at P P₁ after which they are made to pass to the face of
the cloth again and floated over the ground for any desired number of picks N N
and are then tied into the ground as before by any desired number of picks L L'
and so on.

page_text: In Figure 4 the auxiliary pile threads D cross from one piece to the other.
They are first floated over the ground of one piece for any desired number of
picks V, then tied into the ground by any desired number of picks J then floated
over the ground in the same piece for any desired number of picks G and passed
round one or more picks O in the same piece before being crossed over to the other
piece where they are first passed round one or more picks O' in that piece then
Hoated for any number of picks V' then tied in by any number of picks J' then
floated for any number of picks G' then passed round one or more picks O¹ before
returning to the other piece where they are floated and tied in as before.
If it is desired to obtain unequal lengths of pile each thread may be floated over
a different number of picks more or less as a longer or shorter length of pile is
required.
It will be seen that any number of the additional pile threads D may be employed
and that they may be crossed from one piece to the other at regular or irregular
intervals.
As before explained the auxiliary pile threads where they cross from one piece
to the other will be cut at the same time as the other pile threads.
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 manufacture of pile fabrics with two or more lengths of pile by weaving
them as double pile fabrics with pile threads passing across from piece to piece and
with other pile threads floating over the face of the grounds for any desired number
of picks and then passing to the back for any desired number of picks, each float
over the face of a ground being tied in with the ground at one of its ends and
passed loosely through it at the other end so that when cut this end may be drawn
through and brought to their face substantially as described.
2. The manufacture of pile fabrics substantially as herein before described with
reference to Figure 1.
3. The manufacture of pile fabrics substantially as hereinbefore described with
reference to Figure 2.
4. The manufacture of pile fabrics substantially as hereinbefore described with
reference to Figure 3.
5. The manufacture of pile fabrics substantially as hereinbefore described with
reference to Figure 4.
