Improvements in or connected with the Production of Hanks of
Roving of Hemp.
I ROBERT GARRETT CAMPBELL of Mossley Belfast Ireland Flax Spinner do
hereby declare the nature of this invention to be as follows:-
In the ordinary spinning by double rove two strands of ordinary love are rua
in alongside each other in the spinning frame and spun into one thread of yarn but
ordinary rove of hemp, caunot be reelod into hauke, and treated in the form of
hanks as it will not hold together sufficiently
To produce banks of 1oving from hemp, which shall be capable of being handled
and treated by chemicals, or by boiling in an alkaline solution, or otherwise treated
as may be desed I take two or more strands of rove of hemp, and twist them
together, with sufficient twist to make a cord of two or more ply which cord is then
reeled into hanks, which can be handled and treated as desired such as by boiling
in alkaline solution and bleaching or dyeing and if it be treated with chemicals,
the chemicals can be thoroughly washed out of it. The said cord so trented 13
then ready to be wound onto bobbins and put up as love to the spinning frame
before doing which, if so desired, some, or all, of the twist, which was put into it as
nfoi canid, may be removed, which can be done by twisting it in the revciae direction
ou a twisting frame.
The twisting cau be conveniently done on an ordinary twisting frame.

Improvements in or connected with the Production of Hanks of
Roving of Hemp.
I ROBERT GARRETT CAMPBELL, of Mossley, Belfast, Ireland, Flax Spinner.
do hereby declare the nature of my invention, and in what manner the same is to
be performed, to be particularly described and ascertained, in and by, the following
statement:-
In the ordinary "spinning by double rove" two strands of ordinary rove are
run in alongside each other in the spinning frame, and spun into one thread of
yarn, but ordinary love of hemp, cannot be reeled into hanks, and treated in the
form of hanks, as it will not hold together sufficiently.
By trial and experiment I have found that hanks of roving can be produced
from hemp, as hereinafter described, which hauks are capable of being handled
and treated by chemicals, or by boiling in an alkaline solution, or other wise treated
as may be desired.
According to my invention, I take two, or more, strands of love of hemp, and
twist them together, with sufficient twist to make a coid of two, or more, ply,
which cord is then reeled into hanks, which can be handled aud ticated as desired

page_text: such as by boiling in alkaline solution and bleaching, or dyeing, and, if it be treated
with chemicals, the chemicals can be thoroughly washed out of it. The sard cord
of hemp so treated is then ready to be wound onto bobbins and put up as rove to
the spinuing frame before doing which, if so desired, some, oi all, of the twist,
which was put into it as aforesaid, may be removed, which can be done by twisting
it in the reverse direction on a twisting frame.
The twisting can be conveniently done on an ordinary twisting frame.
Having now particularly described aud ascertained the nature of my said
invention and 10 what manner the same is to be performed I declare that what
I claim is :-
1. The production of hanks of roving of hemp, by combining together, by a
twisting operation, two, or more, strands, of rove of hemp, to form a two, or more,
ply cold; as herein before explained.
2. The production of hauks of roving of hemp, by combining together, by a
twisting operation, two, or more, strands of rove of hemp, to form a two, or more,
ply cord, and, after bleaching, dyeing, or otherwise treating, subjecting the said
hanks to a reverse twisting operation to remove, some, or all, of the twist applied
previously as hereinbefore explained.
Dated this 12th day of December 1895.
