Gneisenaustrasse, Berlin, S.W. Prussia, for an Invention of "IMPROVEMENTS
IN FLEECE-DIVIDERS FOR CARDING MACHINES." A communication from
G. Josephy's Erben, of Bielitz, in Austrian Silesia, Empire of Austria.
PROVISIONAL SPECIFICATION left by the said Carl Pieper at the Office
of the Commissioners of Patents on the 20th October 1881.
CARL PIEPER, Civil Engineer and Patent Agent, of 109-110, Gneisenau-
strasse, Berlin, S.W. Prussia. "IMPROVEMENTS IN FLEECE-DIVIDERS FOR CARDING-
MACHINES." A communication from G. Josephy's Erben, of Bielitz, in Austrian
Silesia, Empire of Austria.
The fleece-divider forming the subject-matter of this Invention is represented
on the annexed Sheet of Drawings.
The fleece A coming from the carding-machine passes between the rollers N
and N¹, over which run two series of narrow straps. The straps t of one series,
shown by a thick black line, pass from the roller N₁ around a part of roller N,
over the roller f, downward and around the roller f¹, over the tension-roller 8¹, and
finally back to N¹. The straps u, shown by two parallel fine lines, and which
alternate with the straps t, take their course in a similar manner from N, over a
part of N', around f1, upward and over f and 8, and back to N.
The fleece A in passing between the rollers N and N' is divided by the diverging
straps into ribbons, which are pressed against the said rollers up to the point
where the straps leave them in order to run on the rollers f and f' respectively.
Between the points a and b, and also between a¹ and b¹, the straps of both series
run alongside of each other, in consequence whereof the contiguous straps will
catch the fibres at the edges of the ribbons and detach the latter from the rollers
N and N', so as to secure their being carried around the rollers f and f¹, and to
be delivered to the corresponding apparatus M or M', by which the ribbons aro
rolled into round slub or roving, as usual,

the said Carl Pieper in the Great Seal Patent Office on the 7th February
1882.
CARL PIEPER, Civil Engineer and Patent Agent, of 109-110, Gneisenaustrasse,
Berlin, S.W. Prussia. "IMPROVEMENTS IN FLEECE-DIVIDERS FOR CARDING-
MACHINES." A communication from G. Josephy's Erben, of Bielitz, in Austrian
Silesia, Empire of Austria.
.This Invention relates to improvements in fleece-dividers, i.e., in apparatuses
serving to divide the fleece of wool or other fibrous material produced on a carding-
machine into slivers or ribbons, and to convert such slivers or ribbons into round
slub or roving adapted to be delivered to a spinning-machine.
The improved apparatus is represented on the annexed Sheet of Drawings in a
sectional view.
The fleece A after having been detached from the doffer of the carding-machine
by a vibrating comb or by a roller is conducted around a roller F to the main-
rollers N, N', which are provided with flat grooves corresponding in width to the
fleece-ribbons to be produced, the grooves of one roller alternating with those of
the other roller. In each of these grooves a strap runs, which exactly fills out the
same, so that the rollers present an unbroken surface upon the line where the
fleece is introduced between them..
The straps t of the series belonging to the lower roller N³, and which are shown
in the Drawing by a thick black line, pass from N' around a part of roller N, over
the conducting-roller f, downward and around the conducting-roller f', over the
tension-roller a¹, and finally back to N¹. The straps u, shown by two parallel fine
lines, and which alternate with the straps t, take their course in a similar manner
from N, over a part of N', around f¹, upward and over f and s, and back to N.
In this manner of conducting the straps around the different rollers consists the
main-difference between my correspondent's apparatus and the known systems of
Gesner and Martin.
The fleece in being drawn forward between the rollers N and N¹ is divided by
the diverging straps into as many ribbons as there are straps, and these ribbons are
conveyed upward and downward respectively, while they are pressed by the
straps against the rollers N and N₁ unto the point where the straps leave the said
rollers in order to pass over to the rollers for f¹. Between the points a and b,
and also between a¹ and b', the straps of both series run alongside of each other,
in consequence whereof the contiguous straps will seize the fibres at the edges of
the ribbons and detach the latter from the rollers N and N¹, so as to insure their
being carried around the rollers fand f¹. These hereupon deliver the ribbons to
the corresponding rubbers M or M¹, by which the ribbons are rolled into round
slub or roving, as usual. The material thus produced is finally wound up on the
bobbin-rollers 7, 1, ³, and ³.
The rubbers M and M' are, by preference, close to the straps t and u, as shown
in the Drawing.
The advantages to be attained by the Invention are the following: :-
Firstly. The individual straps are not crossed; they may therefore be made of
any desired width, and they will last longer, as the edges of the straps are not
exposed to any wear.
Secondly. The fleece-ribbons are always in contact with the straps, and provided
only that the rubbers be placed close to the straps the said ribbons will also be
conveyed directly from the straps to the rubber-cloths n and n¹, and not run free
on any point of their course. The apparatus is thus adapted to divide fleeces
consisting of very short fibres, as well as such in which the fibres are long.

page_text: Thirdly. When the cloths of the rubbers M and M' are in contact with the
straps t and u the latter are constantly cleared of adhering fibres by the to and
fro motion of the said cloths.
Having thus described the nature and object of this Invention, and the manner
in which it is to be carried out in practice, as communicated to me by my
correspondent, I hereby claim as new and important features of the same,-
In a fleece-divider for carding-machines the combination of the two series of
conducting-straps t and u with the main-rollers N, N¹, the conducting-rollers f, ƒ³,
the tension-rollers 8, 8¹, and with the rubbers M and M¹, all substantially as and
for the purpose herein before described.
In witness whereof, I, the said Carl Pieper, have hereunto set my hand and
seal, this Eleventh day of December, in the year of our Lord One thousand
eight hundred and eighty one.
