PROVISIONAL SPECIFICATION.
Improvements in or connected with the Spinning of Yarn from
Flax, Hemp, or similar Fibre.
I, JOSHUA VALENTINE EVES, of the Forth River Mills, Falls Road, Belfast,
in the County of Antrim, Ireland, Manager, do hereby declare the nature of this
invention to be as follows:-
In the spinning of flax or linen yarns it has hitherto been customary to pass the
rovings direct from the preparing machinery to the spinning frames any process for
bleaching or boiling being applied either after the yarn was spun or after it was
woven into cloth.
I find that much better results are obtained and a finer yarn can be produced
by bleaching or boiling the material before the final operation of spinning care
being taken that in the process the material is not disarranged or damaged.
In carrying out the invention the fibre is prepared in the usual way for spinning
until the rove is produced. I wind the rove into any suitable form in which the
material will not sustain damage and boil or bleach it in a prepared liquor. At
present prefer to prepare the rove for boiling by winding it into a roll or ball by
a cross-winding machine or a balling machine though it may be prepared in any
other form in which the material will not be damaged and the liquor can penetrate
and act upon all the fibres.
The rove is thus boiled or bleached and is then spun into yarn in a spinning
frame of ordinary construction. The boiling having removed a greater quantity
of the gummy matter from the fibre an evener and better yarm can be produced
and when spun into a pirn or cop can be placed direct into the shuttle for weaving
without the fibres or "make of the yarn being disturbed by the boiling or
bleaching or by any process of reeling or winding to which the yarn is subjected
under the method hitherto adopted.

Improvements in or connected with the Spinning of Yarn from
Flax, Hemp, or similar Fibre.
1, JOSHUA VALENTINE EVES, of the Forth River Mills, Falls Road, Belfast,
in the County of Antrim, Ireland, Manager, 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 :-
In the spinning of flax or linen yarns it has hitherto been customary to pass the
rovings direct from the preparing machinery to the spinning frames any process
for bleaching or boiling being applied either after the yarn was spun or after it
was woven into cloth.
I find that much better results are obtained and a finer yarn can be produced
by bleaching or boiling the material after the rove has been prepared and before
the final operation of spinning care being taken that in the process the material is
not disarranged or damaged.
It consists essentially in winding or cross winding the rove or sliver--after it has
been prepared in the usual way into a cross wound roll or ball so that liquor can

page_text: penetrate to all the fibres and then boiling or bleaching this cross wound rove
preparatory to spinning it into yarn.
In carrying out the invention I dress and prepare the flax fibre and produce a
rove or attenuated sliver in the usual way preparatory to spinning the rove into
yarn.
To enable the fibres of the delicate and slightly twisted rove to be penetrated by
a washing or scouring liquor (either water or an alkaline or acidulated liquor)
without disarranging or entangling any of the fibres I wind the rove into a cross
wound roll or ball in a cross winding or balling machine. When wound in this
forn then boil scour or treat the rove in a prepared liquor in any suitable form
of boiler or vat. It is boiled in an alkaline lye or other liquor which will clcause
and bleach the fibre by removing the adhering glutinous or resinous matters. The
length of time will depend upon the strength of the liquor the quality of the
material and the result desired to be obtained.
When removed from the liquor in which it has been treated the material is
dried in an oven or drying shed or the moisture may be exhausted therefrom by
suction or in a centrifugal machine or by like means or if desired the rove may be
unwound in a wet state and passed direct into the spinning frame.
Although I prefer to prepare the rove in the form of a cross wound roll the
rove may if desired be wound into a ball on a balling machine of ordinary con-
struction or be prepared in any other form in which the liquor can penetrate to
and act upon all the fibres without in any way disarranging entangling or damaging
the fibres.
It will be evident that although I prefer to take the "sliver" in the form known
as "rove "and cross wind and boil it immediately preparatory to entering the
spinning frame the sliver from the last drawing frame, or one of the preparing
frames if made strong enough or with sufficient twist to hold together may be cross
wound into a roll or ball and boiled or bleached and the boiled or bleached sliver
then be passed through a drawing or roving frame and subsequently to the spinning
frame where the finished yarn is produced.
Having removed the greater quantity of the gummy matter from the fibre of the
rove by the boiling or bleaching process to which I have subjected it, I am enabled
to produce a much eveuer, finer and better yarn than I have heretofore been able
to do from the same quality of flax and which when spun into a pirn or cop can be
placed direct into the shuttle for weaving without the fibres or "make" of the
yarn being disturbed, and from which can be produced a stronger, cleaner and
whiter cloth and one more nearly approaching ideally perfect linen than from any
yarn hitherto spun.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what 1
claim is
In the manufacture of yarn from flax hemp or similar fibre the process which
consists in winding the prepared rove into a cross wound roll or ball to permit of a
liquor penetrating all the fibres without entangling or damaging them, and then
boiling or treating the cross wound rove in a prepared liquor to clean or reduce it
and subsequently spinning the same into yarn substantially as described.
Dated this 23rd day of February 1892.
