HERBERT JOHN HADDAN, of Kensington, Middlesex, IMPROVEMENTS IN
MACHINES FOR CUTTING PAPER, a communication from abroad by Gustave
Broussier, of Bruxelles, Belgium,
This invention relates to machines for cutting paper and consists chiefly in
mounting several cutter shafts on the same machine, in order to use it for cutting
paper of different length and width.
I prefer to arrange two cutter shafts or cylinders together with their guiding
and driving mechanism oue over the other, the transverse cuts being effected by
cutting knives fixed to the circumference of a cylinder and parallel to its axis,
while the longitudinal cuts are made by circular knives which cut the paper into
several bands or strips. The paper is conducted to and from the cutters by
adjustable guide rollers, and the necessary tension is obtained by a pulley whose
bearings are secured to one extremity of a double armed lever the opposite arm of
which carries an adjustable weight. The driving shaft for every set of cutters is
mounted to the base of the machine and the motion is transmitted to the cutters
by means of a belt or rope and cone pulleys in order to vary the speed in
proportion to the different qualities of paper to be cut.

"IMPROVEMENTS IN
MACHINES FOR CUTTING PAPER," a communication from abroad by Gustave Broussier
of Bruxelles, Belgium,
The principal object of these improvements is to cut at the same time two or
more sizes of different lengths and width from the same band of paper without
the least stoppage of the machine with the result of considerable economy in time
and hand work. In the accompanying drawing which illustrates the invention
Fig. 1 represents a band of paper cut on the principle of this cutting machine.
This band A B is first cut into two or more parts of different length, subsequently
while one part of the band of paper A B passes the knives to be divided into a
given size, the other part of the band C D E passes another set of knives to be cut
into a different size in the same space of time. Fig. 2. represents a top view of the
cutting machine. Fig 3 a general elevation of the machine. Fig. 4. a plan and
section along x y.
a is the frame of the upper mechanism. a' the frame of the lower mechanism.
bare reels on which the paper leaving a paper-machine is rolled up. c is a roller
conducting the paper coming from the reels b. d d is a pair of feed rollers for the
paper, the upper roller fixed on the shaft is rotated by means of pulley du
driven by means of a driving belt from any given motor. The diameter of
part of the upper feed roller is larger in order to avoid the formation of folds
in the band of paper passing between the said rollers d; e e are circular knives.
The paper leaving the feed rollers & passes between the knives e which cut it
longitudinally into two or more bands of equal or different width. These knives e e
receive a rotary motion by means of toothed wheels e¹ fixed on their axles.
These wheels are driven by a toothed wheel el which is fixed on the shaft d'. The
shafts with the circular knives turn in opposite directions so that each pair of
circular knives acts on the band of paper which they cut in the same way as a
pair of scissors. The bands of paper when leaving the knives e are taken up by
another pair of feed-rollers ƒ ƒ which are driven by means of toothed wheels. e.
One part of the bands of paper leaving the rollers ffis led on a horizontal board
the edge of which faces the steel blade of a transverse knife f¹ fixed on carriers g.
The carriers g and consequently the knives f¹ are caused to rotate by the toothed
wheel which wheel is mounted on the shaft g¹ and set in motion by means of
pulley h and a driving belt h¹ which passes over pulley fixed on shaft d'. The
blade of the transverse knife passing in front of the edge of the board meets the
band of paper as it advances and cuts it horizontally. A given size of paper is
thus obtained. To obtain smaller sizes it will only be necessary to fix two or three
knives similar to f¹ on carrier g, in consequence of which the band of paper will
be met oftener by the knives and thereby cut into smaller sizes.
Once the paper
is cut into the size required it falls on the endless felt i passing over the tension
rollers. This endless felt which receives a continuous motion by means of
pulley and belt conducts the cut paper on a wooden table where it is piled
up. If it is required to cut another size (different from the first) at the same time
it will be sufficient to lead part of the band of paper leaving the feed-rollers fon
the stretching appliance k fixed on the frame of the upper cutting mechanism.
This stretching appliance is provided with counterweight and oscillates on the
axis k. From this stretcher k the paper passes to the feed rollers m constructed

page_text: in the same manner as those in the lower part of the machine. One of the
rollers m is fixed on a shaft m¹ on which is keyed a cone-pulley n which by means
of a belt is driven from pulley d" keyed on the shaft d' of the lower part, of the
cutting machine. Leaving the rollers m, the paper passes directly on a horizontal
board in front of whose edge pass the blades of the knives p fixed transversely on
the carriers p' the shaft of which is provided with a toothed wheel p" driven by
means of pulley g and belt q¹ passing over pulley q". The paper cut into the
given size falls on the endless felt r which receives a continuous motion by means
of roller and pulley driven by means of the belt. The endless felt r
conducts the cut paper on a tables where it is piled up or distributed as it leaves
the felt.
The result is that while the lower part of the machine cuts pieces of paper of a
given length and width the upper part of the same cutting machine cuts pieces of
paper of a given length and width different from the above at the same time and
from the same band of paper, without any stoppage in the working of the machine.
t. are pulleys which serve to stretch more or less the driving belts. vare rollers
which serve to stretch the felt conducting the cut paper. The part 1. 2. 3. 4. of
the lower frame-work is moveable and can be shifted horizontally on the lower
main frame round a point which serves as a pivot. This moveable part supports
the knives f. If this moveable part 1, 2, 3, 4, of the lower machine is shifted the
knives fare placed obliquely in respect to the band of paper which comes in front
of them. Therefore if the said moveable part is set at the required angle the
paper is cut to a rhombic shape which is the form suitable for the manufacture
of envelopes. In cutting the paper in this manner a great loss of paper is avoided.
What I claim is
1. The construction of the new paper cutting machine substantially as described
in above specification and represented by the accompanying drawings.
2. The construction and arrangements according to this system of any machine
cutting at the same time two or more sizes of different length or width from one
or more superposed bands of paper leaving the circular knives.
3. The application of this system not only to the machine represented in the
drawing, but to any machines for the same purpose whether the principal
mechanism or sections of the machine be superposed or placed in series.
4. The arrangement for supporting the transverse knives and cutting at a given
angle, substantially as described and represented by Figures 1. 2. 3. and 4.
In witness whereof I, the said Herbert John Haddan, have hereunto set my
land and seal this twentieth day of October AD. 1882.
