Improvements in the Manufacture of Paper and Cardboard Boxes
and in the Machinery Employed therein.
I, WILLIAM HARVEY, of 9 Grosvenor Street, Piccadilly, Manchester, in the County
of Lancaster, Paper Merchant, do hereby declare the nature of this invention to be
as follows:-
In the manufacture of paper and cardboard boxes it is now customary to employ
two or more machines to cut and score the blanks from which the boxes are to be
made.
The object of my invention is to cut the blank to shape to remove the corner pieces
and to score the blank where necessary for folding or bending longitudinally and
transversely at one operation.
To effect this I in one instanco employ a revolving cutter and scoring roller or
tool mounted in adjustable bearings at each side of the machine frame to prepare
the sides of the cardboard and in order to remove the corners and cut and score
the board to complete a blank employ a special bed or frame on to which are
secured the necessary transverse knife and scoring lip or surface as well as the
knives for cutting out the corner pieces this bed or frame is carried by a shaft
supported in the machine frame and free to be rotated means being arranged to set
the bed and knives &c., nearer to or further from the axis of the shaft to alter the
size or length of the blanks to be cut.
Either the shaft or the table of the machine (or both) is arranged to be adjusted
vertically and a pressure roller also adjustable is employed to lie upon the cardboard
when being cut by the knives in the bed or frame.
The cardboard to be cut into blanks for boxes.is fed at the desired speed
between guides over the table and under the pressure roller its longitudinal edges
being cut and scored and the transverse cuts and scoring and removal of the corner
pieces being carried on continuously by the machine which may be.worked by steam
or hand power.
By changing the knives in the bed or the position of the bed and adjusting tho
revolving cutters the size of the blanks can be altered as required.
For cutting small blanks the bed for the knives may be dispensed with and
the knives may be fixed in grooves, cut in the shaft and in place of an independent
frame and revolving cutters suitable adjustable discs may be secured to the same shaft
by which dises the sides of the cardboard may be cut and scored.
I propose to employ suitable springs or equivalents to prevent waste pieces of
cardboard adhering to the bed between the knives and scoring surfaces.
By duplicating the mechanism several blanks of the full width of a sheet of
cardboard may be cut simultaneously.
When finger or thumb slots are required in box lids I propose to fit independent
knives or cutters in a separate bed or attached to the main bed to cut such slots when
the shaft rotates.

Improvements in the Manufacture of Paper and Cardboard Boxes
and in the Machinery Employed therein.
I, WILLIAM HARVEY, of 9 Grosvenor Street, Piccadilly, Manchester, in the County
of Lancaster, Paper Merchant, do hereby declare the nature of this said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In the manufacture of paper and cardboard boxes it is now customary to employ
two or more machines to cut and score the blanks from which the boxes are to be
made.
The object of my invention is to cut the blank to shape to remove the corner
pieces and to score the blank where necessary for folding or bending longitudinally
and transversely at one operation i.e. in a single machine.
To effect this I in one instance employ a revolving cutter and scoring roller or
tool mounted in adjustable bearings at each side of the machine frame to prepare
the sides of the cardboard and in order to remove the corners and cut and score the
board to complete a blank I employ a special bed or frame on to which are secured
the necessary transverse knife and scoring lip or surface as well as the knives for
cutting out the corner pieces this bed or frame is carried by a shaft or other axis
supported in the machine frame and free to be rotated means being arranged to
set the bed and knives &c. nearer to or further from the axis to alter the size or length
of the blanks to be cut.
Either the axis or the table of the machine (or both) is arranged to be adjusted
vertically and a pressure surface or roller also adjustable is employed for the cardboard
to lie upon when being cut by the knives in the bed or frame.
The cardboard to be cut into blanks for boxes is fed at the desired speed.
between guides over the table and over the pressure surface or roller its longitudinal
edges being ent and scored and the transverse cuts and scoring and removal of
the corner pieces being carried on continuously by the machine which may be worked
by steam or hand power.
By changing the knives in the bed or the position of the bed and adjusting the
revolving cutters the size of the blanks can be altered as required.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings reference being had
to the figures and letters marked thereon.
Similar letters refer to similar parts throughout the several views.
invention for
Fig. 1 is a side elevation of a machine made according to
my
cutting and scoring longitudinally and transversely and removing the corner pieces
from a cardboard blank at one operation. Fig. 2 is a front view of the main portion
of the same on an enlarged scale. Fig. 3 is a sectional end view of the special
transverse cutting and scoring bed or frame. Fig. 4 represents a modification of one
bed or frame several of which are shown in combination in Fig. 3 Fig. 5 is an
alternative form of the cutter and scorer illustrated by Fig. 3 and represents the
different beds for the cutters all brought as near as possible to their centre. Fig. 6
represents part of a sheet of cardboard after passing through the machine the
different blanks although separated longitudinally and transversely are placed side
by side to illustrate the operation of the machine.
In these views-a is the machine frame, b a sheet of cardboard, which is fed
through the machine in the direction indicated by the arrow in Fig. 1 c is a series of
circular cutters and scorers mounted adjustably in brackets & supported in slideways a
in brackets a² for cutting or dividing the cardboard and scoring the same longitudinally
as ate and f respectively in Fig. 6 this operation is common in the manufacture of
cardboard boxes.
The special bed or frame shown is composed of say four beds or frames g secured
adjustably by bolts at each end of the machine to a disc g' mounted on a stud g

page_text: carried in adjustable bearings on the machine frame a and provided with suitable
cutting off knives scoring tools and knives for removing the corner pieces upon
each of the beds g in this instance are mounted a transverse cutting knife scoring
tools i and cornering knives; the cuts and scores made by these tools are indicated
by letters and respectively on Fig. 6.
The stud g or other axis is driven by gearing not shown preferably from the axle
of a pressure roller and at the same surface speed as the latter.
It is evident that the blanks will be completely cut, scored and divided by
passing a sheet of cardboard through the machine as shown in Fig. 1 at one
operation.
In order to increase the length of the boxes it is only necessary to set out the
beds g further from the centre of the discs gl and raise the discs in their bearings by
which means many different sizes of boxes can be cut out without changing any of
the tools for cutting scoring and cornering. The cornering knives and scoring tools
or blades i can be changed when the depth of the boxes to be made varies and the
number of beds g on the discs can also be varied.
Any suitable bed such as a roller k as shown is employed to support the cardboard
while being cut and scored.
In place of employing detachable knives scorers and cornering tools these might be
formed out of a solid piece of metal and secured to the bed g.
By duplicating the mechanism several blanks of the full width of a sheet of
cardboard may be cut simultaneously as shown in Fig. 6.
When finger or thumb slots are required in box lids I propose to fit independent
knives or cutters in a separate bed or attached to the main bed to cut such slots when
the shaft rotates.
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 :-
1. In paper and cardboard box making machinery the construction use and
application of a transverse cutting and scoring and cornering appliance composed
of say four or other number beds or frames which carry the knives or cutting tools
and are mounted adjustably upon discs or equivalents supported adjustably upon the
machine frame substantially as and for the purposes herein set forth.
2. The combined arrangement of cutting and scoring and cornering knives whereby
blanks of various lengths can be cut transversely and cornered by simply adjusting
the distance of the beds or frames with said knives from the centre of the supporting
discs or equivalents substantially as and for the purposes herein set forth.
3. The combination with an appliance for longitudinally cutting and scoring card-
board blanks, of the special appliance for transversely cutting and scoring and
cornering the same substantially as herein set forth.
