PROVISIONAL SPECIFICATION.
Improvements connected with the Combing of Rhea and similar
Inelastic Fibres.
We, JAMES LONGMORE, Mill Manager, and ROBERT WILLIAMSON, Merchant,
both of 34 Leadenhall Street, in the City of London, do hereby declare the nature
of this invention to be as follows:-
'
This invention relates to the treatment of inelastic fibres more particularly
rhea fibres and has reference more especially to the combing process.
In a combing machine where the fibres are drawn through the teeth of the comb
by nipping mechanism it is found that unless the material is fed in in a perfectly even
thickness as shown by a section the nipping mechanism will bite only the thicker
parts and slip over the thinner parts of the supply.
If the ordinary way of feeding a comb by a number of parallel slivers were
applied to inclastic vegetable fibres they would not sufficiently amalgamate as do
slivers of elastic fibres such as silk, wool, mohair and the like, to present an even
thickness to the nipping mechanism but would always show an imperfect union
and thickness between the slivers and if this uneven thickness were presented to the
nipping mechanism the thicker parts would be liable to be cut by the jaws of
the nip and the thinner parts slipped over and unevenly drawn out thus rendering
the combing impracticable.
-
This invention is designed to overcome the before mentioned difficulty by forming
the material into a lap of perfectly uniform transverse thickness before feeding it
into the combing machine:"
This is effected by first passing the slivers through a gill box where they are
drawn out to a thin film of the width of the lap required.
This film in its full width is then wound upon a drum until it is of the thickness
desired to be introduced into the comb at which time the circular or practically
endless lap then on the drum is torn open and wound in the form of a lap of its
full width on to a suitable roller or core at which stage it is ready to be introduced
into the comb.
When it is desired to increase the thickness of the sliver resulting from the
combing machine two or more of the before mentioned laps may be simultaneously
fed into the machine or as before explained the thickness of the lap formed on the
drum may be increased.

COMPLETE SPECIFICATION.
Improvements connected with the Combing of Rhea and similar
Inelastic Fibres.
We, JAMES LONGMORE, Mill Manager, and ROBERT WILLIAMSON, Merchant,
both of 34 Leadenhall Street, in the City of London, 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 treatment of inclastic fibres more particularly rhea
fibres and has reference more especially to the combing process.
In a combing machine where the fibres are drawn through the teeth of the comb
by nipping mechanism it is found that unless the material is fed in in a perfectly

page_text: even thickness as shown by a section the nipping mechanism will bite only the
thicker parts and slip over the thinner parts of the supply.
If the ordinary way of feeding a comb by a number of parallel slivers were
applied to inclastic vegetable fibres they would not sufficiently amalgamate as do
slivers of elastic fibres such as silk, wool, mohair and the like, to present an even
thickness to the nipping mechanism but would always show an imperfect union and
thickness between the slivers and if this uneven thickness were presented to the
nipping mechanism the thicker parts would be liable to be cut by the jaws of the
nip and the thinner parts slipped over and unevenly-drawn out thus rendering
the combing impracticable.
This invention is designed to overcome the before mentioned difficulty by forming
the material into a lap of perfectly uniform transverse thickness before feeding it
into the combing machine.
This is effected by first passing the slivers through a gill box where they are
drawn out to a thin film of the width of the lap required.
This film in its full width is then wound as many turns as may be required upon
a drum until it is of the thickness desired to be introduced into the comb at which
time the circular or practically endless lap then on the drum is torn open and
wound in the form of a lap of its full width on to a suitable roller or core at
which stage it is ready to be introduced into the comb. The tearing open of the
lap may be effected by inserting a rod, blade or equivalent device between it and
the periphery of the drum and pulling said rod outwards from the drum.
When it is desired to increase the thickness of the sliver resulting from the
combing machine two or more of the before mentioned laps may be simultaneously
fed into the machine or as before explained the thickness of the lap-formed on the
-described.-
2. In the treatment of rhea and similar inelastic fibres preparatory to feeding it
to a comb through which they are drawn by nipping mechanism passing the slivers
through a gill box where they are drawn out to a thin film and winding said film
upon a drum to form a lap of uniform thickness throughout its width substantially
as and for the purpose described.
