COMPLETE SPECIFICATION.
An Improved Method and Apparatus for Bundling and Binding
Fibrous Materials for Making Brooms, Brushes, and the like.
I JOHANNES SANDER of Rodingsmarkt 34, Hamburg, in the Empire of Germany,
Merchant, do hereby declare the nature of this invention and in which manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:―
This invention consists in an improved method and apparatus for mechanically
bundling and binding fibres or fibrous materials for the manufacturing of brooms,
brushes and the like, whereby which a considerable superiority of product and
saving of cost is obtained over hand labour, since the bundles produced by this
improved method are on the one hand exactly uniform and more secure than such:
made by hand and on the other hand 2 persons are enabled to produce the same
amount of product as 10 persons would make by hand in the same time.
The improved method consists in taking a very large number of the fibres and
presses them together by a band a with their ends even and then bringing their ends
end wise against a rapidely rotating tubular tool formed with a sharpened edge or
annular rim, so that the latter penetrates the bundle of fibre and surrounds the ends
of a few therein, while the end of a thread or cord, drawn from a reel rotating with
the tool, rapidely winds around the fibres enclosed and held within the tube and
binds them in a small bundle. If now the whole bunch of fibres is withdrawn and
then moved a little side ways and again pushed on the end of the tube, so that the
latter encloses another group of fibres the edge of the tube will sever the cord from
that wound about the first bundle; and proceed to wind around the new group
which, when done, is again cut off by sideward moving of the fibres and so on, till
one after another the whole bunch of fibres is brought against the binder. The
surrounding band a is then loosened, when the whole of these fibres will be found
to be grouped in a number of small bound bundles, with only a few interposed loose
fibres, which are collected and added to the next filling of the holder a.
The invention is illustrated by the annexed drawings, in which
Fig. 1 shows a side view of the apparatus, used for the aforesaid purpose,
Fig. 2 plan of the tubular end of the tool,
Fig. 3 an end view in section thereof,
Fig. 4, 5 & 6 show respectively side and front view and ground plan of a bunch
of such fibres compressed within a holding band a some being bound,
Fig. 7 shows a single small completed bundle.
In Fig. 1 b represents a rapidely rotating spindle supported in bearings 6¹ with a
tubular end c sharpened on its edge, this tube having its interior diameter corre-
spondent to the thickness of the desired bundles Fig. 7; d is a reel placed to
rotate in the interior of the spindle.
The end of the cord or thread wound around this reel is first passed outward and
then through a bore i arranged near the point of the tube piece c into the side of
the interior cavity thereof. c' is a lapping spring for tensioning the cord.
If now a bunch of fibres be brought end ways against the point c, it is evident, that
the cord must wind itself in consequence of the rotating motion of the spindle around
those fibres, the ends of which have entered the end of the tube c.
When this bundle now is withdrawn out of the tube with the rest of the fibre and
moved sideways, the cord end 1 (as to be seen by Fig. 4) is cut off by the sharp edge
of the tube when brought against this, while another group of fibres enters the tube
to be bound, by the cord.
This process is repeated until the whole bunch of fibres is transformed into a
number of small bundles by pressing the bunch again and again always with slight

opened and the different bundles are separated from the few remaining loose fibres,
which latter are collected to be formed into bundles in the described manner in
another bunch...
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:
1) The improved method of bundling and binding fibres consisting in enclosing a
considerably large quantity of such fibres as a bunch in a temporary band or holder a
and bringing same repeatedly against a rapidly rotating tubular tool with sharp
edges, whereby the tube penetrates the bunch and encloses a group of the fibres,
binds them together by a cord rotating with the tube.
2) An improved apparatus for bundling and binding fibres consisting of a spindle b
with tubular end c; this spindle carrying a reel d rotating therewith and having on
its end a bore i whereby the cord or thread from said reel may be passed into the
side of the interior of the tube for the purpose set forth.
