Improvements in the Manufacture of Cardboard Boxes of any suitable
Form and Material, and in Apparatus therefor.
A communication by ALBERT BERAN and IGNAZ MEISSNER, both of
I Graben 29, Vienna, in the Empire of Austria, Mechanician and
Manufacturer, respectively.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster, 118, New Street, Birmingham in
the County of Warwick and 322, High Holborn in the County of Middlesex, Civil
Engineer, 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 method of manufacture by which
cardboard boxes of any suitable shape and size with metal bound edges or with
simply gummed edges may be easily and rapidly produced, and consists essentially
in the employment of a specially constructed machine by means of which the
cardboard boxes are simultaneously cut out of the material, pressed into shape and
bound with metal or the like at the corners.
The mode of working is as follows :—
The cardboard blank is cut out of the material by means of an automatically
operated cutter. This blank is then pressed into the shape of a cardboard box by
means of an automatically operated stamp or punch, and finally the edges of the
box already pressed into shape are bound with metal, or provided with adhesive
flaps which are bent round and placed in such a way that the boxes delivered only
require to be stuck together. The machines serving for making the boxes are
preferably made double acting in such a way that on one side of them cardboard
boxes with metal bound edges are produced, whilst on the other side a modified
form of box namely with adhesive edges or flaps, is produced.
The devices for clamping or binding the cardboard edges are of the usual well
known construction, but their peculiar arrangement and their automatic action in
this machine are deemed to be new.
The machine, or rather the cutter and stamps therein employed, may further be
so shaped that boxes of round or oval form may also be produced. In this case of
course the process for effecting the metal binding or producing the adhesive flaps
is dispensed with.
In the accompanying drawings is shown a machine of the kind herein before
described,

page_text: assume any desired position. Rollers 55 carry in the ordinary manner the binding
strip or band m which is suitably pushed forward by the wellknowa pushing forward
mechanism after each operation.
By the constant moving forward of the bolt 39 in the closing position, the bolt 43
is also moved outward and the cone 45 forces the slide rollers 50 to yield, whereby
the arms 52 together with the heads 54 are moved on to the impressing stamp 35
now projecting quite freely out of the counterknife 36 and thus also against the
cardboard box held on the said stamp, Figure 9, whereby the metal binding is
effected on all the four edges of the cardboard box simultaneously. Simultaneously
with the metal binding the metal band is cut through at suitable places in the usual
manner so that the binding device can, when its work is completed, again freely
move away from the impressing stamp.
In most cases it is necessary however to further impress the bottom of the box
with ornamentations, inscriptions or the like. This takes place by suitably engraving
the faces of the stamps 35 and 41 in such a way that in the end movement of the
bolt 43 it strikes against a fixed set screw 57, so that at the conclusion the
impressing of the hottom takes place. After this operation the impressing
stamp 35 again commences its return movement, whilst bolts 35 and 41 follow
this movement and the slide rollers 50 again travel down the cone, and the
binding devices again assume their normal position. The finished box is finally
forced through the countercutter 36 by the bolt 43 and falls finished out of the
countercutter 36.
After this process the cutter 29 commences to hasten forward, and the process of
working hereinbefore described is again repeated.
The opposite side B of the machine is exactly similarly built, only in this case
the means for binding or clamping the edges is dispensed with, as here such
modified cutters and stamps are inserted that cardboard boxes with gummed edges
may be produced.
The cutters and stamps for making these boxes are shown more particularly in
Figures 18-22. For making a cardboard box with gummed edges the blank
must have the form shown in Figure 23. Here in addition to the ordinary
cardboard blank the adhesive flaps D have to be cut out and brought into the
proper position.
The mode of manufacture or rather the cutting out of the blank C with its
flaps D takes place exactly as before by means of cutters 61 and countercutters 62,
(see Figures 1, 10 and 11). As appears from Figure 24 however the fastening
flaps D must be bent round before the side walls are pressed up.
This takes place by means of arms 63 which are revoluble on pins 64 on the
stamp and the countercutter 62. These arms 63 form elbow levers, the parts 65
of which encounter the pins 64 opposite to them and thus the movement of the
arms 63 is limited. Weights 66 and cords or the like 68 running over rollers 67
always in part to the arms 63 the correct position, Figure 21. The impressing
stamp 69 is adjustable within the countercutter 62, and on said stamp, pins 69* are
mounted in such a way that on the return movement of the impressing stamp 69
they encounter the parts 65 of the elbow levers and cause these parts to move
outward, so that the arms 63 move towards one another, Figure 21. The fixed
countercutter 62 is also perforated at the points 70 so that the flaps D may pass
through as soon as the impressing stamp comes into action and only the side
parts C and C be bent round. The bending of the side parts C3 and C* remains
uneffected until the recesses 71, Figure 194 of the cutter 62 are held back.
During the time in which the impressing stamp 41 moves forward and only bends
up the sides C1, C2, this stamp forces the counterstamp 69 to move backwards.
Before the moment however in which the edges 71* bend round the other side
parts C3 and C, the pins 69" encounter the elbow levers 65 and the arms 63
quickly close together, and bend up the flaps D, after which the ends of the
box C3 C are bent round on the shoulders or edges 71ª. When this work is

are caused to produce ornamental impressions on the bottom of the box, substantially
as described.

the arrangement of arms (63) revoluble on pins (64) and standing under the
impulse of weights or springs, which arms are adapted to be engaged and moved
by pins (69) on the counterstamp (69) in such a way as to fold up the fastening
flaps (D) within recesses (71) after which the other side parts (C3, C4) which are
not provided with flaps are finally pressed up by shoulders or edges (71"), on a
further movement forward of the impressing stamp (41) substantially as described.
