PROVISIONAL SPECIFICATION.
Improvements in Wet-spinning for Flax or like Yarns. :
JOHN MCFERRAN of Barnagecha Fort William Park Belfast Ireland Merchant
and JOHN BARBOUR PIRRIE of Green Edge Carrickfergus Ireland Mill Manager do
hereby declare the nature of this invention to be as follows:-
These improvements relate to the wet spinning of flax or like yarns upon tubes to
which the yarn will adhere after being dried thereon.
In making wet spun yarns of flax and similar fibres it is usual to dry the yarns
either after winding them into hanks or to dry the yarn on the bobbins upon which
it is wound in spinning in the latter method the evaporation of the moisture from the
yarn causes it to shrink and so become slack upon the bobbin.
The object of this invention is to provide a core or tube upon which the wet yarn
is wound during spinning and to which the yarn will adhere whilst and after being
dried so that wet spun yarns of flax and like fibres can be spun in the form of cops
with a cheap base or tube like what cotton yarns are spun upon.
This object is effectually accomplished by these improvements in wet spinning for
flax or like yarns which consist in winding the yarn during the process of spinning
upon a thin tube of paper or other suitable material this tube is carried by a
bobbin or socket which is free to revolve upon the spindle in flyer spinning frames
and in ring spinning frames this bobbin or socket is driven by the spindle.
When the desired quantity of wet spun yarn has been wound upon the thin tube it
will be tight upon the socket owing to its being damp the yarn thin tube and bobbin
or socket as a whole are lifted off the spindle and removed to a suitable place for
drying the process of drying causing the bobbin or socket to become free from the
thin paper tube which is left adhering to the dried yarn which can thus be either
woven in shuttles reeled or otherwise unwound from the thin tube or base. The
bobbins or sockets after drying being returned to the spinning frames to be re-covered
with the thin tubes and filled with yarn.
By this method of spinning wet yarns upon a thin tube separable from the bobbin
or socket after drying and yet adherent to the yarns the yarns whether spun upon
ring or flyer frames are in a convenient form for either weaving or winding and
upon an inexpensive base or holder.

Improvements in Wet-spinning for Flax or like Yarns.
JOHN MCFERRAN of Barnageeha Fort William Park Belfast Ireland Merchant,
and JOHN BARBOUR PIRRIE of Green Edge Carrickfergus Ireland Mill 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:
These improvements relate to the wet spinning of flax or like yarns upon tubes to
which the yarn will adhere after being dried thereon.
In making wet spun yarns of flax and similar fibres it is usual to dry the yarns
either after winding them into banks or to dry the yarn on the bobbins upon which
it is wound in spinning. In the latter method the evaporation of the moisture from
the yarn causes it to shrink and so become slack upon the bobbin.
The object of this invention is to provide a core or tube upon which the wet yarn

dried so that wet spun yarns of flax and like fibres can be spun in the form of cops
with a cheap base or tube like what cotton yarns are spun upon.
This object is effectually accomplished by these improvements in wet spinning for
flax or like yarns which consist in winding the yarn during the process of spinning
upon a thin tube of paper or other suitable material this tube is carried by a bobbin
or socket which is free to revolve upon the spindle in flyer spinning frames and in
ring spinning frames this bobbin or socket is driven by the spindle.
When the desired quantity of wet spun yarn has been wound upon the thin tube
it will be tight upon the socket owing to its being damp. The yarn thin tube and
bobbin or socket as a whole are then lifted off the spindle and removed to a suitable
place for drying the process of drying causing the bobbin or socket to become free
from the thin paper tube which is left adhering to the dried yarn which can thus be
either woven in shuttles reeled or otherwise unwound from the thin tube or base.
The bobbins or sockets after being dried are returned to the spinning frames to be
re-covered with the thin tubes and filled with yarn.
By this method of spinning wet yarns upon a thin tube separable from the bobbin
or socket the yarns whether spun upon ring or flyer frames are in a convenient
form for either weaving or winding and upon an inexpensive base or holder.
We know that paper tubes or bases are used in spinning cotton and woollen cops
but in the spinning of flax and like yarns by the wet process a difficulty arises in
making the yarn adhere to the tube when dry and it is to overcome this difficulty
that we employ thin flexible paper tubes which remain in cop until it is unwound or
woven thus overcoming the difficulty which is experienced when rigid paper tubes
are employed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The use of thin flexible paper tubes as a vehicle for wet spun flax or like yarns
during the processes of spinning and drying for the purpose of unwinding or
'weaving.
