IMPROVEMENTS IN MACHINERY FOR CUTTING CHENILLE
Year: 1885

page_text: I, JAMES MOGHEE of 46 Clyde Street, Calton, Glasgow in the County of
Lanark North Britain Foreman chenille cutter, do hereby declare the nature of my
said invention for "IMPROVEMENTS IN MACHINERY FOR CUTTING CHENILLE," to be
as follows, that is to say:-
My said Invention relates to machinery used for cutting into strips of chenille
the web primarily woven for the purpose of making chenille, and its object is to
construct the roller by which the web is presented to the rotating cutters, in an
improved manner and so that the pile or fur of the chenille may be very equal in
length.
In the primary web the material to form the pile or fur is interwoven as weft
with sets of warp threads separated by intervals, these warp threads forming what
is termed the backbone of each strip of chenille; and the wefts are cut along the
middles of the intervals between the sets of warp threads to divide the web into
separate strips of chenille.
When the web is being cut it is passed round a roller formed with indentations
or grooves running round it, and the rotating cutters enter these grooves and cut
the weft in doing so. Hitherto great difficulty has been experienced in getting the
web to pass round the grooved roller with the backbones or sets of warp threads
exactly midway between the grooves, which is necessary for getting the fur or pile
of uniform length; but by the present Invention great accuracy in this respect is
obtained by means of projecting points fixed in a peculiar manner in the otherwise
plain surface of the roller between the grooves. In each space between two
grooves there are two rows of projecting points or pins, fixed in inclined positions,
the space between the roots of the two rows of pins at the surface of the roller
being equal to about the width of the backbone of the chenille, whilst the rows of
pins are inclined outwards from each other so that their points are wider apart.
As the web passes upon the roller the pins freely penetrate between the weft
threads ou each side of each backbone and they guide the backbone down into its
proper central position in contact with the surface of the roller.
The contrivance is very simple but very effective and of great practical value.

I, JAMES MCGHEE, of 46 Clyde Street, Calton, Glasgow, in the County of
Lanark, North Britain, Foreman chenille cutter, 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, that is to say:
My said Invention relates to machinery used for cutting into strips of chenille
the web primarily woven for the purpose of making chenille, and its object is to
construct the roller by which the web is presented to the rotating cutters in an
improved manner and so that the pile or fur of the chenille may be very equal in
length.
In the primary web the material to form the pile or fur is interwoven as weft
with sets of warp threads separated by intervals, these warp threads forming what
is termed the backbone of each strip of chenille; and the wefts are cut along the
middles of the intervals between the sets of warp threads to divide the web into
separate strips of chenille.
When the web is being cut it is passed round a roller formed with indentations
or grooves running round it, and the rotating cutters enter these grooves and cut
the weft in doing so. Hitherto great difficulty has been experienced in getting the
web to pass round the grooved roller with the back bones or sets of warp threads
exactly midway between the grooves, which is necessary for getting the fur or pile
of uniform length; but by the present Invention great accuracy in this respect is
obtained by means of projecting points fixed in a peculiar manner in the otherwise
plain surface of the roller between the grooves. In each space between two grooves
there are two rows of projecting points or pins, fixed in inclined positions, the space
between the roots of the two rows of pins at the surface of the roller being equal
to about the width of the backbone of the chenille, whilst the rows of pins are
inclined outwards from each other so that their points are wider apart. As the
web passes upon the roller the pins freely penetrate between the weft threads on
each side of each backbone and they guide the backbone down into its proper
central position in contact with the surface of the roller.
The contrivance is very simple but very effective and of great practical value.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing part of a chenille cutting machine as
made with my improvements.
Figure, 1, is a transverse vertical section and figure, 2, is a sectional front
elevation showing part of the rotating cutter drum of a chanille cutting. machine
and my improved roller for presenting the web to the cutters.
A large drum, 3, of the usual construction and which has the cutters, 4, for
cutting the web, 5, into strips of chenille fixed to it by their blocks or holders, 6, in
the usual manner, is held in bearings in the upper part of a framing, not shown,
but which may be of any suitable construction. The roller, 7, for presenting the
web, 5, to the cutters, 4, is made with grooves in its surface for the cutters, 4, to
work in. In the surface of the roller, 7, between each of the grooves two rows of

page_text: projecting points or pins, 8, are fixed in any suitable manner, and so that the spacé
between the roots of the two rows of pins, 8, at each surface between two grooves,
is equal to about the width of the backbone of the chenille. The rows of pins are
inclined outwards from each other their points being wider apart. A roller, 9, is
held beneath the roller, 7, for guiding the web, 5. This roller, 9, is formed with
corrugations in its surface and is so held in the framing of the machine that the
hollow parts in its surface are beneath or opposite the parts between the grooves
of the roller, 7. The warp threads which form the backbone of each strip of
chenille lie in these hollows and when the machine is in action the web, 5, passes
under this roller, 9, and upon the roller, 7. The pins, 8, then freely penetrate
between the weft threads on each side of each backbone; and they guide the
backbones down into their proper central positions on the surface of the roller, 7.
The cutters, 4, then act on the weft threads in such a manner that the pile or fur
obtained will be of uniform length.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
'

In machinery for cutting chenille, fixing in the roller which presents the web to
the rotating cutters, two rows of inclined projecting points or pins in each space
between two grooves, substantially in the manner and for the purpose hereinbefore
described.
