PROVISIONAL SPECIFICATION.
Improvements in or connected with the Production of Hanks of
Roving of Flax.
I, ROBERT GARRETT CAMPBELL, of Mossley, Belfast, Ireland, Flax Spinner
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to produce hanks of roving from flax which hanks
are capable of being handled and treated by chemicals as desired, or treated by
boiling in an alkaline solution, or otherwise treated as may be desired.
Ordinary rove cannot be reeled into hanks and treated in the form of hanks as it
will not hold together sufficiently. In what is known as double rove two strands of
ordinary rove are run in alongside each other in the spinning frame and spun to one
thread of yarn.
According to my invention I take the two stands of rove and twist them
together (which may be done on an ordinary twisting frame) and I put in enough
twist to make a two ply cord which is then reeled into hanks which can be boiled
in alkaline solution and bleached or dyed as may be wished and if they be treated
with chemicals, the chemicals can be thoroughly washed out of them. The said
cord is then ready to be wound on to bobbins and put up as rove to the spinning
frame before doing which, if so desired some, or all, of the twist which was put into
it, may be removed, which can be done by twisting it in the reverse direction on a
twisting frame.

Improvements in or connected with the Production of Hanks of
Roving of Flax.
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 :-
The object of my invention is to produce hanks of roving from flax, which
banks are capable of being handled, and treated by chemicals as desired, or treated
by boiling in an alkaline solution, or otherwise treated as may be desired.
Ordinary rove of flax cannot be reeled into hanks, and treated in the form of
hanks, as it will not hold together sufficiently. In what is known as "spinning by
double rove," two strands of ordinary rove of flax are run in alongside each other
in the spinning frame, and spun into one thread of yarn. According to my
invention I take the two strands of rove of flax and twist them together, (which
may be done on an ordinary twisting frame), and I put in enough twist to make a
two-ply cord which is then reeled into hanks, which can be boiled in alkaline
solution, and bleached, or dyed, as may be wished, and if they be treated with
[Price 8d.1

page_text: chemicals, the chemicals can be thoroughly washed out of them. The said two-ply
cord, so formed of flax, is then ready to be wound onto bobbins, and put up as rove
to the spinning frame, before doing which, if so desired, some, or 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.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Hanks of roving of flax in which there are two strands of rove of flax combined
together by a twisting operation so as to form a cord as hereinbefore explained.
2. Hanks of roving of flax in which there are two strands of rove of flax combined
together by a twisting operation to form a cord as described, which is bleached,
dyed, or otherwise treated, and then subjected to a reverse twisting operation to
remove some, or all, of the twist previously applied; as hereinbefore explained.
Dated this 12th day of December 1895.
