Improvement in Apparatus for Dividing Double Woven Pile Fabrics.
We, JULIUS ZIMMERMANN and AUGUST SCHWAAG, Manufacturers, both of
Drensteinfurt, Westphalia, Germany, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our invention relates to a new device for cutting or dividing double woven
stuffs as for instance velvet, plush which as it is well known is hitherto woven
on a suitable loom in double fabric and divided in the same loom by a recipro-
cating knife. The many drawbacks resulting from this known method has
caused us to depart from the same and manufacture the fabric in such a manner
that the double stuff is woven on a loom without a cutting arrangement and
then cut or divided in a special machine adapted for this purpose. One feature
of our invention consist therefore in the combination, in a cutting machine
with a series of rollers having a raw circumferential body such as will enable
any stuff to be drawn and held fast, of gearing to revolve said rollers of a cutting
arrangement located in front or before the drawing rollers. This combination
and the construction of the cutting arrangement enables us to cut or divide a
double woven piece either that each half is of equal height or different height or
thickness.
In the accompanying drawings
Figure 1 is a vertical cross section of a machine, embodying our invention;
Figure 2 is a vertical elevation seen from the front side;
Figure is a plan;
Figure 4 is a cross section through the cutting or dividing device in an enlarged
scale;
Figure 5 shows the fabric to be cut.
Similar letters of reference designate corresponding parts in all the figures
a designates two vertical standards which are held together by bolts so as to
form the framing of the machine. In this framing is rotatably journalled a
roller e upon a shaft c¹. Directly below the roller c a roller d'is mounted in
the framing the shaft e of which carries a toothed wheel f into which meshes a
like wheel keyed to the shaft c. On shaft e is fixed a driving pulley g
which transfers motion to the rollers c, d, and which may also be effected by
hand by means of the crank shown in dotted lines in Figure 2.
The rollers c, d are not close together but so far mounted from each other
that a stuff of any thickness may pass between them. They have a circum-
ferential raw body which may be obtained in any manner. In the present
example the face of each roller is provided with wire neddles or the like so
that the roller may seize the stuff and carry it forwards.
In front of the rollers nearly over the whole latitude of the framing is arranged
the cutting arrangement for the stuff the construction of which may be best
understood from a glance of Figure 4 and the following description:
To the standards a are cast at the inner sides supporting lugs
upon which
is fastened a knife holder i. This holder is combined of two pieces which

page_text: have a tapered form in cross section and leave between them a depression 22
in which fits a knife k, that is jammed between the holders when they are
tightened up by screw bolts k¹. As seen from Figure 3 the blade of the knife
and according thereto the holder is slanted in the horizontal plan: By means of
suitable slots the holder i with the knife may be adjusted.
To the inner side of the standards a are also cast another supporting lugs m
to which is fixed a shoe./ by lugs m and screw bolts n. Said shoe is made hollow
so that it may cover the holder and its knife & forming together therewith
channels above and below the holder and entrances at the side of the knife
blade.
2
The upper screw hole n is formed to a slot which allows the shoe 7 to be
turned round the lower screw the effect of which is that the entrances a of
the channels are made unequal. Before the cutting device there is arranged
a table plate and before said plate in arms o¹ of the standards a are located
a pair of rollers one above another. The upper one is provided with a grooved
disk s over which is guided a weighted coil so that the upper roller may press
upon the lower one.
The working of our machine is as follows:
The double woven stuff after leaving the loom is guided between the rollers »
where it is gently pressed together, passes then the table surface 2 and enters
then the shoe. It may be mentioned that to the upper and lower face of the
stuff a piece of cloth is sewed so as to pull the stuff forwards. In entering the
shoe the stuff is cut or divided by the blade which is done very easy in
consequence of the slanted' blade in two pieces, one piece going through the
upper channel, the other through the lower one and then both halves are
seized each by a roller c, d respectively and then collected in a box. If the
blade has the position shown in Figure 4 the stuff is divided exactly in the
middle so that both halves are of equal height or thickness. If however the
shoe is positioned, as shown in dotted lines the entrances are made unequal
and then the stuff is cut after the line -y Figure 5 each halve being thien
of different height or thickness so that I attain two different pieces of ware
from one stuff which hitherto was impossible.
The blade with its holder may be also drawn more inwards or outwards within
the shoe. In this case the channels are enlarged or diminished and a more or
less thick stuff may pass them in order to be cut.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1) In a machine for cutting or dividing double stuff such as velvet, plush and
the like the combination with two rollers having a raw circumferential_body
arranged one above another, of a cutting or dividing device as illustrated and
for the purpose set forth.
2) In a machine for cutting or dividing double stuff such as velvet, plush
and the like the combination with two rollers having a raw circumferential
body arranged one above another, of a cutting or dividing device said device
consisting of a shoe within which is arranged a holder having jammed a knife
said knife having a slanted blade both elements forming channels =
entrances as illustrated and for the purpose set forth.

3) In a machine for cutting or dividing double stuff such as velvet, plush
and the like the combination with two rollers having a raw circumferential
body arranged one above another, of a cutting or dividing device consisting
of a shoe covering a holder with a knife said shoe may be turned up or down
round a bolt and fixed in this position as illustrated and for the purpose set
forth.
4) In a machine for cutting or dividing double stuff such as velvet, plush
and the like the combination with two rollers having a raw circumferential

knife holder i, k said holder being arranged to be removed from or approached to
the entrance of the shoe as illustrated and purpose set forth.
5) In a machine for cutting or dividing double stuff such as velvet, plush
and the like the combination with two rollers having a raw circumferential
body arranged one above another of a cutting or dividing device, of a table plate
arranged in front of said cutting device and of a pair of rollers arranged in
front of the plate and means to press the rollers together as illustrated and
for the purpose set forth.
