PROVISIONAL SPECIFICATION.
Improvements in or relating to the Preparation of Rhea Fibre for
Spinning.
I, JAMES LONGMORE, of 34, Leadenhall Street, in the City of London, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the preparation of rhea fibre for spinning and has for
its object the removal of kemps or hard ends usually present in rhea fibre.
This kemp consists of thick fibres of a woody nature and different to the true
fibre; their presence is objectionable in the production of good yarns, and
especially fine numbers as they cause thick places in the yarn, and also dye
a different shade in the cloth or yarn to the true fibre with which they are mixed.
It is found that these kemps are very much more brittle than the true fibre,
and advantage is taken of this to draw the sliver after a first combing
through a system of fine drawing frames with fallers of close pitch, usually 5 per
inch, and of fine pinning of about 50 to 60 per inch. Repeated passages of the
sliver break the hard ends down to very short lengths, owing to their brittle-
ness and extra thickness, while not injuring the true fibre, which is readily
drawn even through such fine pinning. The sliver is then recombed, and the
kemp is taken out with the noil.
Dated this 10th day of January 1898.

Improvements in or relating to the Preparation of Rhea Fibre for
Spinning.
I, JAMES LONGMORE, of 34, Leadenhall Street, in the City of London, Engineer,
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:―
This invention relates to the preparation of rhea fibre for spinning and has for
its object the removal of kemps or "hard ends" usually present in rhea fibre.
This kemp consists of thick fibres of a woody nature and different to the true
fibre; their presence is objectionable in the production of good yarns, and
especially in fine numbers as they cause thick places in the yarn, and also dye
in the cloth or yarn a shade different from that of the true fibre with which they
are mixed.

page_text: It is found that these kemps are very much more brittle than the true fibre,
and advantage is taken of this fact by drawing the sliver after a first combing
through a system of fine drawing frames with fallers of close pitch, usually 5 per
inch, and of fine pinning of about 50 to 60 per inch; repeated passages of the
sliver break the hard ends down to very short lengths, owing to their brittle-
ness and extra thickness, while not injuring the true fibre, which is readily
drawn even through such fine pinning. Good results have been obtained by
passing the sliver eight or nine times through the fine drawing frames. The
sliver is then recombed, and the kemp is taken out with the noil.
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 preparation of rhea fibre for spinning the employment of fine drawing
frames to break up kemps or hard ends in the sliver after it has had a prelim-
inary combing.
