Improvements in the Manufacture of Yarn, and Apparatus therefor.
A communication by EMIL CLAVIEZ, of 1, Davidstrasse, Leipzig, in the Empire
of Germany, Manufacturer.
I, William PhillipsS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester both
in the County of Lancaster, 118, New Street, Birmingham in the County of
Warwick and 322, High Holborn, in the County of Middlesex, Civil 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 has for its object in conjunction with Patent No. 2394295 a
process for making a durable yarn from paper in combination with a suitable
fibrous material such for instance as flax, hemp, cotton or the like, and an
apparatus for the carrying out of same.
This process is more particularly characterized by the paper which is here
employed being made in the form of a roll and cut longitudinally into narrow
strips, which strips are passed through suitable chemicals as described in
Patent No. 239425 in order to render the strips supple. The strips while still
moist are wound each on a suitable reel, which is then placed on a device such
as will be hereinafter described adapted to wind or twist the strip on to a thread of
fibrous material while the strip is being drawn off the reel by drawing-off rollers.
By the twisting operated by this device a cotton or the like thread is so wrapped
round by the strip of paper that the drawing-off rollers draw a perfectly round
thread from off the reel, which thread may be employed for weaving and other
like purposes, so that by this means a considerably cheaper product is produced
which is not inferior in durability to cotton and the like threads.
It must also be pointed out that the fibrous material employed for strengthening
this thread may be of very moderate quality.
In the accompanying drawings, Figure 1 is a vertical section of the apparatus
employed and Figure 2 a modified form of construction.
The
As regards the apparatus employed, its arrangement is as follows: A reel a
which holds the narrow paper strip wound thereon is placed over a sleeve or
holder b, the latter having a spring c which produces a firm connection between
the reel and the sleeve or holder. The holder b is loosely mounted on a spindle s,
and beneath the reel a fork or fly f is firmly connected with the spindle s.
spindle s is perforated longitudinally so that the fibrous material 9 employed
may be carried through the spindle from a spool A. By the fly f being rotated
by a cord or belt and belt-pulley mounted on the spindle the strip of paper h
is wound or twisted round the fibrous material so that a perfectly twisted thread
may be drawn off by the drawing rollers through a guide eyelet i.
The modified form of construction shown in Figure 2 consists in that both
the thread and also the paper strip h is wound on the same reel a¹ which also

8.
The loop or eyelet y of the fly f¹ then receives
both threads g and which by this means are twisted into a single thread.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:-
1. An improved manufacture of yarn or thread from paper in connection with
the process described in Patent No. 2394295, consisting in the suitably prepared
paper strip being wound on a reel and twisted with a second thread of a suitable
fibrous material which is suitably conveyed or fed thereto directly before the
commencement of the twisting of the yarn so that by the twisting said second
thread is combined with the paper strip into a single thread and spun, sub-
stantially as hereinbefore set forth.
2. A device for carrying out the herein before described process, of making a
yarn from paper, consisting of a reel (a) wound with a paper strip and mounted
on a holder or sheath (b) which is suspended on the actual spindle (s) and con-
nected with the reel by means of a spring, the said spindle s being perforated to
allow of a thread (g) of suitable fibrous material being passed through it, so
that the revolving fly (f) fixed to said spindle winds the strip of paper (h) round
the thread (g) and twists them together, substantially as described.
3. A modification of the device herein before described, consisting in the paper
strip and the thread of fibrous material being wound on the same reel (a¹), so that
the fly (f) in its rotation can produce a combined twisting of the thread (g) and
paper strip (h) substantially as described.
