IMPROVED METHOD OF PREPARATION IN COMBED WOOL FINE SPINNING
Year: 1886

page_text: I PETER LUDWIG KLEIN of Dusseldorf in the Kingdom of Prussia and Empire
of Germany, Machine Maker, do hereby declare the nature of my invention for
IMPROVED METHOD OF PREPARATION IN COMBED WOOL FINE SPINNING to be as
follows:-
The manufacture of combed wool yarns consists of three distinct and separate
operations.
The first consists of carding and combing the wool on the carding engine and
combing machine, on which the burrs are removed, the wool equalized and
combed, and the combed wool formed into a sliver.
The second operation, called the "Preparation," is that of thinning out and
parallelizing this sliver and preparing it for the spinning machine by forming it
into roving yarn, which is then passed on to the
Third operation of spinning on the spinning machine.
My invention relates to the second operation, called the "Preparation" being the
treatment of the combed wool coming from the combing machine until it is formed
into roving yarn ready for the spinning machine; and it consists in substituting
carding engines for a certain number of the drawing frames now used in this
operation of Preparation, whereby not only a great saving in the machinery
necessary for this operation is effected, but also its cost materially reduced..
As now practiced the operation of Preparation is as follows.
"
The combed wool coming from the combing machine is passed through a number
of drawing frames, varying from 7 to 13 according to the material used, the two
last of these frames being called the finisher and the fine finisher. The combed
wool coming from the combing machine is passed through a gillbox and formed
into slivers, which are then passed to the first drawing frame, on which 3 or 4
slivers are united and thinned out into a single one; of these latter 3 or 4 are
again united on the second drawing frame and thinned out into a single one; and
in this way the single slivers coming from each drawing frame are united by
fours, threes and gradually by twos, and thinned out on the next following one,
until they reach the finisher and fine finisher, on both of which only two slivers
are united and drawn out into one, the fine finisher delivering the roving yarn

page_text: ready for the spinning machine. The entire operation is a very tedious and
expensive one, each frame having to be attended by at least one person, and it
requires considerable time to pass a given quantity of material through all of these
frames.
By my improved method the operation of preparation is greatly simplified, the
time required for the same greatly reduced, to about one half, and its expense
lessened in about the same proportion.
For all the drawing frames mentioned above as being now used with the
exception of the finisher and fine finisher which I retain, I substitute two carding
engines, the first of which I call the Preparing Card, while I term the second the
Thinning Card. While in the method as now used, the material coming from the
combing machine has to be formed into a sliver by the latter or by a gillbox, in
order to be passed through the drawing frames, I bring the combed wool either in
shape of loose flakes, or of slivers or pieces of slivers onto the feedtable of the
Preparing Card which is arranged to equalize and parallelize the combed wool
fibres, the material leaving the delivery end of the Preparing Card in the shape of
a sliver, which, being brought to the Thinning Card, is while passing through the
same and being further equalized and parallelized, thinned out to such a degree,
that the bobbins delivered by this Thinning Card and then passed to the finisher,
are exactly equal to those, which in the old method have passed through the entire
train of gillboxes and drawing frames previous to reaching the finisher.
In the old method the bobbins prepared on one gillbox or drawing frame, have to
be arranged on the next frame, and the latter stopped meanwhile, as also when one
bobbin having run off, has to be replaced by a fresh one, which causes a great loss
of time. In my improved method any given quantity of combed wool can be run
through the two cards which I employ, in a continuous operation, delivering the
bobbins to the finisher in about one half the time required therefor in the old
method, while also only one hand is required for attending the two carding engines,
thereby saving greatly in actual wages.
There is no novelty in the construction of either the Preparing or the Thinning
Card both being carding engines of well known construction; but never heretofore
have carding engines been employed in the operation of Preparation in combed
wool fine spinning, being the production of roving yarn for the spinning frame from
combed wool coming from the combing machine.
I do not therefore claim any novelty in the construction of the carding engines
which I employ in the operation of Preparation; but neither do I confine myself to
the number of them as I may, according to the material, find one of them sufficient
for my purpose, or I may employ more than two, a saving of time and actual
expense resulting in any case.
But what I claim as new and desire to secure by letters patent is.
1st The improved method of using carding engines in the process of Preparation
in combed wool fine spinning, substantially as and for the purpose herein described.
2nd In the process of Preparation in combed wool fine spinning, the substitution
of carding engines for the train of gillboxes and drawing frames, with the exception
of the finisher and fine finisher, substantially as herein described.
