Improvements in Sliver Dividing Devices for Carding Machines.
Year: 1894

page_text: PROVISIONAL SPECIFICATION.
Improvements in Sliver Dividing Devices for Carding Machines.
I, ALPHONSE BORIOS of La Sarraz, Canton de Vaud, in the Republic of
Switzerland, Spinner's Mechanic, do hereby declare the nature of this invention to
be as follows:-
My invention has reference to improvements in sliver dividing devices for carding
machines and consists of a thin sheet of metal provided with rows of elongated
openings or slots the number of which varies according to the nature of the textile
material operated upon and the number of slivers to be obtained.
The accompanying drawing more clearly shows my invention and 1 will proceed
to describe it with reference to the said drawing.
Figure 1 is a side view of the apparatus. The sheet of metal is placed imme-
diately over the main card drum of the machine (lettered A) around which it is
partially wrapped and its ends are attached to rollers C and B. It is thus located
between the main drum and the doffing cylinders E and D.
In Figure 2 this sheet of metal is shown in front elevation, illustrating the two
rows of openings K and J through which the doffing cylinders come in contact with
the material. It is arranged that these rows of openings stand opposite the spaces
left between the openings of the subsequent or previous row, thus presenting
different surfaces to be operated upon.
The rollers C and B effect alternately one third of a revolution to the right and
left so as to partially wrap and unwrap the dividing sheet and thus cause it to travel
in a vertical direction.
The action of my invention is as follows:
On the machine being set in motion the various rollers and drums rotate in the
direction shown by the ai rows and the doffing cylinders E and D, working through
the rows of openings K and J strip off portions of the material which being passed
between and pressed by the auxiliary doffing cylinders G and F and rollers H and I
forms the sliver the width and length of which depends upon the size of the openings
in the metal sheet.

Improvements in Sliver Dividing Devices for Carding Machines.
I, ALPHONSE BORIOS of La Sarraz, Canton de Vaud, in the Republic of
Switzerland, Spinner's Mechanician 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 :-
My invention has reference to improvements in sliver dividing devices for carding
machines and consists of a thin sheet of metal provided with rows of elongated
openings or slots the number of which varies according to the nature of the textile
material operated upon and the number of slivers to be obtained.

page_text: The drawings accompanying the Provisional Specification clearly showed my
invention and I will proceed to describe it with reference to the said drawing.
Figure 1 is a side view of the apparatus. The sheet of metal is placed imme-
diately over the main card drum of the machine (lettered A) around which it is
partially wrapped and its ends are attached to rollers C and B. It is thus located
between the main drum and the doffing cylinders E and D.
In Figure 2 this sheet of metal is shown in front elevation, illustrating the two
rows of openings K and J through which the doffing cylinders come in contact
with the material. It is arranged that these rows of openings stand opposite the
spaces left between the openings of the subsequent or previous row, thus presenting
different surfaces to be operated upon.
The rollers C and B effect alternately one third of a revolution to the right and
left so as to partially wrap and unwrap the dividing sheet and thus cause it to travel
in a vertical direction.
The action of my invention is as follows:-On the machine being set in motion
the various rollers and drums rotate in the direction shown by the arrows and the
doffing cylinders E and D, working through the rows of openings K and J, strip
off portions of the material which being passed between and pressed by the auxiliary
doffing cylinders G and F and rubbers H and I forms the sliver the width of which
depends upon the size of the openings in the metal sheet.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In sliver dividing devices for carding machines the use of a slotted metal band
such as that shown on the drawing through which work the doffing cylinders D
and E, the sliver made by such operation being passed between and pressed by the
rubbers H and I, all substantially as described for the purposes set forth and as
illustrated on the drawing.
