An Improved Mode of Cutting Out and Grooving or Indenting
Cardboard, Millboard, Paper, Thin Wood, and other Materials
from which to form Boxes and other articles.
I, ROBERT SANSON, JR., of Mary Villa, Canaan Lane, Edinburgh, Printer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved mode of cutting out and grooving or
indenting cardboard, millboard, paper, thin wood, and other materials from which
to form boxes and other articles.
In this invention the cutting and grooving or indenting of the material is
performed at one operation and in a novel manner.
In carrying out my invention for, say, making cardboard blanks for fancy
boxes I set up, in a suitable frame, a number of cutting blades which may be
straight or curved according to the shape of the blank to be cut. Arranged, also
in the frame, if it is also desired to groove the cardboard, are grooving knives or
strips. These grooving knives or strips are set up in the frame at a slightly lower
level, corresponding to the depth of the grooves desired, than that of the cutting
blades.
Preferably, instead of making an actual groove in the material I make indenta-
tions or partial perforations, at the parts of the material to be bent or folded, by
means of serrated or toothed knives or strips which are arranged at a lower level
than that of the cutting blades.
The frame with its knives properly fixed therein is placed upon a travelling
table of any well known and suitable construction and the cardboard or other
material from which the blank is to be cut is properly set on top of the frame.
The table is then caused to travel underneath a pressure roller or cylinder of any
well known and suitable construction and the cardboard is subjected to a pressure
sufficiently heavy to cause the knives to cut and (or) indent the material in the
proper manner. Mechanism of any well known construction may be provided
for catching the cardboard sheet after being cut and delivering it on to a table or
other place. Ordinary grip and fly mechanism may be used for this purpose.
Instead of using a travelling table and a stationary pressure roller a stationary
table and travelling pressure roller may be used.
In some cases it may be desirable to arrange the frame with its knives on a
stationary table and use a vertically moving stamp head or platen to give the
proper pressure when cutting the material, or, vice versa, the frame with its knives
may be arranged on a vertically moving stamp head or platen whilst the material
to be cut may be laid on a stationary table.
The cutting blades and also the indenting or grooving blades can at any time
be taken out of the frame and rearranged therein so as to cut a different pattern
blank.
The cutting and grooving blades may be made of any desired shape or shapes
to suit the different classes of work

page_text: Sets of knives of different sizes and shapes may be kept in stock and when
desired suitable knives from the sets may be picked out and arranged in the frame
so as to cut any desired shape of blank."
The knives, when properly set up in a frame, may be kept permanently in
position by filling up the spaces round the knives with lead or other metal or
material so as to make the whole frame with the knives therein one solid casting
or block.
In order to cause the cardboard or other material to fly or lift up off the knives
when cut, india rubber, cork, or other resilient cushions may be arranged in the
spaces between the knives.
Uncut pieces are preferably left at the corners of the blank to prevent it
falling out of the sheet when cut.
It is possible with this invention to cut or indent or cut and indent longitudin-
ally and transversely at the one operation.
The blades have preferably a big bevel on one side and a slight bevel on the
other.
A backing sheet may be used when cutting out the blank. Or the cylinder may
be padded with paper, lead, or other soft material.
Sets of frames with knives may be used for cutting out a series of blanks at one
operation.

An Improved Mode of Cutting Out and Grooving or Indenting
Cardboard, Millboard, Paper, Thin Wood, and other Materials
from which to form Boxes and other articles.
I, ROBERT SANSON, JR., of Mary Villa, Canaan Lane, Edinburgh, Printer, 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:
-
This invention relates to an improved mode of cutting out and grooving or
indenting cardboard, millboard, paper, thin wood, and other materials from which
to form boxes and other articles.
In this invention the cutting and grooving or indenting of the material is
performed at one operation and in a novel manner.
In carrying out my invention for, say, making cardboard blanks for fancy
boxes I set up, in a suitable frame, a number of cutting blades which may be
straight or curved according to the shape of the blank to be cut. Arranged, also
in the frame, if it is also desired to groove the cardboard, are grooving knives or
strips. These grooving knives or strips are set up in the frame at a slightly lower
level, corresponding to the depth of the grooves desired, than that. of the cutting
blades.
Preferably, instead of making an actual groove in the material I make indenta-
tions or partial perforations at the parts of the material to be bent or folded by
means of serrated or toothed knives or strips which are arranged at a lower level
than that of the cutting blades.
The frame with its knives properly fixed therein is placed upon a travelling
table of any well known and suitable construction and the cardboard or other
material from which the blank is to be cut is properly set on top of the frame.

page_text: The table is then caused to travel underneath a pressure roller or cylinder of any
well known and suitable construction and the cardboard is subjected to a pressure
sufficiently heavy to cause the knives to cut and (or) indent the material in the
proper manner. Mechanism of any well known construction may be provided
for catching the cardboard sheet after being cut and delivering it on to a table or
other place. Ordinary grip and fly mechanism may be used for this purpose.
Instead of using a travelling table and a stationary pressure roller a stationary
table and travelling pressure roller may be used.
In some cases it may be desirable to arrange the frame with its knives on a
stationary, table and use a vertically moving stamp head or platen to give the
proper pressure when cutting the material.
The cutting blades and also the indenting or grooving blades can at any time
be taken out of the frame, and rearranged therein so as to cut a different pattern
blank.
The cutting and grooving blades may be made of any desired shape or shapes
to suit the different classes of work.
Sets of knives of different sizes and shapes may be kept in stock and when
desired suitable knives from the sets may be picked out and arranged in the frame
so as to cut any desired shape of blank.
The knives, when properly set up in a frame, may be kept permanently in
position by filling up the spaces round the knives with lead or other metal or
material so as to make the whole frame with the knives therein one solid casting
or block.
In order to cause the cardboard or other material to fly or lift up off the knives
when cut, india rubber, cork, or other resilient cushions may be arranged in the
spaces between the knives.
Uncut pieces are preferably left at the corners or sides of the blank to prevent it
falling out of the sheet when cut.
It is possible with this invention to cut or indent or cut and indent longitudin-
ally and transversely at the one operation.
And in order that my said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings, which shows, by way of example,
a convenient mode of carrying my invention into effect or practice.
Referring to the drawings:
Fig. 1 is a partial plan view of the travelling carriage of an ordinary printing
machine.
Fig. 2 is a partly sectioned side view of the same.
Fig. 3 is a plan view of the form or frame with the cutting and grooving or
indenting knives fitted therein.
Fig. 4 is a view of a sheet of paper A. as it appears after being cut and grooved.
Fig. 5 is a perspective view of a cardboard box and Fig. 6 is a view of a blank
from which the box is made.
}
'
The frame or form a is held in place on the bed of the carriage b by means of
furniture c and the usual printer's side stick d. Secured firmly in place within
the form a by means of furniture e are a number of separate blocks or pieces f, f₁₂
f², f f f f f², f³, f³, f¹º, f¹¹, f12, 13, 14, 15, preferably made of cast metal and
shaped so as to suit the pattern of blank to be cut from the cardboard or other sheet.
The knives 9 for cutting and the knives g¹ for indenting or grooving are fitted
between the blocks or pieces as shown at Fig. 3. The cutting knives are prefer-
ably made of thin steel or brass strips having sharp bevelled cutting edges whilst
the grooving or indenting knives are preferably made from steel or brass strips
having sharp serrated or toothed edges. The knives rest upon the bed of the
carriage in a vertical position and are held in place by the blocks f aforesaid.
In the cardboard sheet shown at Fig. 4 the heavy black lines h indicate the parts
cut through whilst the dotted lines h¹ indicate the parts merely indented or
grooved. Either of the sides h2, h3, may be, as shown, merely grooved or indented

page_text: for the purpose of retaining the blank in position in the sheet so that it can be
flyed easily. These parts h³, h³, can be subsequently cut by a guillotine knife.
In order that they may only partially cut through the cardboard at the places
where it is to be merely grooved the grooving knives are made or set a little lower
than the other knives.
The sheets from which the blanks are to be cut are passed into the machine in
the manner shown at Fig. 2 and when the carriage is travelled in the direction of
the arrow, the roller 2, owing to its teeth meshing with the rack teeth of the
carriage, is revolved in the direction of the arrow. The combined movement of
the carriage and roller presses the sheet ; upon the knives in the form or frame and
as a consequence cuts and indents it. according to the pattern desired.
is a backing sheet.
The blank when cut is of the shape shown at Fig. 6 and when folded up makes
a box such as shown at Fig. 5.
Any well known and suitable arrangement of travelling table or carriage and
stationary revolving roller mechanism, or of stationary table and revolving and
travelling roller mechanism can be used.
The blocks and the knives can be so shaped and arranged as to cut and (or)
indent paper or cardboard sheets to any desired pattern of blank.
The blades have preferably a big bevel on, one side and a slight bevel on the
other.
A. backing sheet may be used when cutting out the blank. Or the cylinder may
be padded with paper, lead, or other soft material.
Sets of frames with knives fitted therein can be arranged on the carriage so as to
cut out a series of blanks at one operation.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is
1. The method of making blanks from which to form collapsible or folding
boxes wherein the sheets are pressed by roller or platen pressure upon a number of
knives properly arranged upon a flat surface and held in place thereon by blocks
or pieces, substantially as set forth.
2. In combination, a frame or form, knives formed of separate strips fitted
therein and blocks or pieces for retaining the knives in place, substantially as and
for the purpose set forth.
