PROVISIONAL SPECIFICATION.
Improvements in the Winding of Wet Spun or Sized Yarn of Flax
and similar Fibres.
I, JOSHUA VALENTINE EVES, of the Forth River Mill, Falls Road, Belfast,
in the County of Antrim, Ireland, Mill Manager, do hereby declare the nature of
this invention to be as follows:-
This invention is designed to a large extent to obriate or dispense with a separate
process of drying yarn which is spun and wound in a wet condition and to allow of
its being sized when it is being unwound off the bobbin or pirn and also to do the
drying at a time that will not affect the make or strength of the yarn.
It consists in drying the yarn as it is wound onto the spindle pirn bobbin roll
reel or the like by means of a blast of air caused to impinge thereon and in the
apparatus therefor.
It is mainly serviceable in the winding of the yarn, after being spun, into cross
wound rolls but it may also be applied to ordinary drum winders or upright spoolers
for headed bobbius or to any rewinding processes through which wet yarns have to
be put. A pipe with suitable nozzles or apertures is carried along adjacent to the
winding drums or rollers in such a position as to be able to cause a current of air
to be blown or brought to impinge upon the yarn at the point where it begins to be
wound onto the roll. The pipe is connected with a fan or blower or other source of
air under pressure and from the apertures a current of air either hot or cold is
constantly directed upon the yarn which passes through the interstices of the cross
wound roll carrying away the moisture therefrom. In the cross winding frame in
addition to or instead of the air pipe a heated cylinder or table may be applied
over which the yarn cau pass to drive off the moisture therefrom. The yarn for
this process of winding is brought direct from the wet spinning frame without
the ordinary and usual intermediate process of drying.
The piru or yarn may if desired to assist the process of wet winding be
immersed or the yarn led into a trough of water or where sized yarn is
required into a trough containing the size as I am by this process of drying
during winding enabled to size the yarn before being wound and still wind it
into a roll direct.

COMPLETE SPECIFICATION.
Improvements in the Winding of Wet Spun or Sized Yarn of Flax
and similar Fibres.
I, JOSHUA VALENTINE EVES, of the Forth River Mill, Falls Road, Belfast,
in the County of Antrim, Ireland, Mill Manager, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :—
This invention is designed to a large extent to obviate or dispense with a

page_text: separate process of drying yarn which is spun and wound in a wet condition and
to allow of its being sized when it is being unwound off the bobbin or pirn and
also to do the drying at a time that will not affect the make or strength of
the yarn.
It consists essentially in drying the yarn by means of a blast of air caused to
impinge thereon during the process of winding into cross wound rolls or headed
bobbins without any intermediate process of drying after the yarn has been spun
wet or sized.
It will be fully described with reference to the accompanying drawings.
Fig 1. Transverse section of winding frame in which the yarn is wound wet from
the bobbin or pirn upon which it has been spun.
Fig. 2. Transverse section of winding frame showing sizing of yarn as it passes
from the bobbin to winding frame.
Fig. 3. Transverse section of winding frame for winding from bobbin onto
upright warpers bobbin.
Referring to Fig. 1. an ordinary type of drum winding machine is illustrated,
A being the winding drums. Above the winding drums A running longitudinally
of the frame I place an air trunk or pipe B of rectangular or other suitable shape
provided at intervals with apertures or slots facing the winding drums. Connected
to the air trunk or pipe B in any suitable position is an air propeller or fan C by
which a draught of air can be forced into the pipe B. The trunk or pipe B may
instead of being provided with a fan C be connected with any other source of air
under pressure.
In the interior of the trunk or pipe B steam pipes D may be
placed to heat the air therein to enable it to absorb or take up a greater amount
of moisture. From the slots or apertures ba draught or current of air is constantly
playing upon the yarn during the process of winding. The yarn on a bobbin or in
the form of a pirn E or E' is placed upon the machine in the wet state in which it
leaves the wet spinning frame without the ordinary or any intermediate process of
drying and while it is being wound into a cross wound roll or upon headed bobbins
or in other form upon the drum A the current or draught of air which is constantly
directed upon it through the apertures from the trunk B passes through the
interstices or otherwise plays upon it and carries away the moisture therefrom
producing a dry roll when finished.
Referring to Fig. 2 in the modification therein shown the machine is similarly
constructed (like letters of reference and description referring to like parts) with
the addition of the sizing trough G and brush H by which the yarn is sized as it
passes from the bobbin E to the winding drum A. The yarn in either a wet or
dry state is placed upon the machine at E and passes through the size in the
trough G to the cross wound roll a in the winding drum A the brush H removing
any excess of size from the yarn. As the yarn is wound into a roll upon the drum A
a continuous current of air plays upon it and through the interstices of the roll
drying the yarn as it is rolled up.
Referring to Fig. 3 between the double headed upright bobbins a¹ on the
spindles A or at the side of the bobbins a' I place the pipe or trunk B with
slots or slits & cut therein opposite each bobbin. The air is forced out through
these slits to play upon and dry the yarn as it is wound upon the hobbins in
the manner hereinbefore described.
The invention may be applied to winding frames in which yarn is rewound onto
any form of bobbin or spools or into any form of roll or pirn.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I now declare that
what I claim is :-
1. In the process of winding yarn into rolls or upon headed bobbins or the
like the use or application of a forced draught or current of air continuously
playing upon the yarn as it is wound so that it may be wound direct from a
wet spinning frame or after being sized substantially as described.

page_text: 2. The combination with a rewinding frame for winding yarn into cross wound
or other rolls or the like of an air pipe or trunk provided with apertures or slots
opposite the bobbin or roll whereby a continuous forced draught or current of
air is forced to play upon the yarn as it is wound to dry it substantially as
described.
3. The combination with a rewinding frame for winding yarn into cross wound
or other hobbins of a size trough or sizing apparatus through which the yarn is
passed to size it and an air pipe or trunk provided with apertures or slots opposite
the winding drums through which a blast or air is forced and impinges upon the
sized yarn as it is wound up to dry it.
