.Improvements, in the Manufacture of Cardboard Boxes.
I, JOSEF TEMLER, of Warsaw in the Empire of Russia, and of 30
to 34 Tabernacle Street in the County of London, Manufacturer 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 principally to the manufacture of boxes of coloured
cardboard, which are not intended to be covered with paper after the box is:
formed.
The
process is carried out in the following manner. The pieces of cardboard
used correspond in length to the side walls of the boxes which they are employed
in fórming, while as regards their width, it will be presently seen how it is
determined. At a distance from their edges, corresponding to the width of the
side walls of the box to be formed, these pieces of cardboard are provided with
ribs a, Figs. 1 and 2 of the accompanying drawings, which are produced by
gathering the substance of the cardboard on a machine such as that described in
the Specification of the British Patent No. 23735 of 1692 or by some suitable
stamping process or the like, and which project on the lower side of the cardboard,
thereby rendering, the cardboard capable of being folded at those parts. Owing
to the formation of these ribs the outer portions or strips of the piece of card-
board take up an inclined position, or become inclined relatively to the portion c
of the cardboard, comprised between the two ribs, as illustrated in Fig. 2.
When the pieces of cardboard have thus been prepared, they are covered with
suitable adhesive material at the said part c, between the ribs a, and are then divided
into two equal parts or halves by means of a cut either in zigzag, as shown in
Fig 3, or undulating, as represented in Fig. 4 or some similar cut. Each of these
balves will accordingly have one rib a and with a zigzag, undulating or other like
edge, and be adapted to form the side wall or walls of the box.
The width which such piece of cardboard intended to form the side walls of the
box, should have imparted to it, is therefore equivalent to the height of two side
walls, plus the quantity of material (which experience will enable to he
determined) required for the formation of the ribs, and the width of the zigzag or
undulating cut.
When a strip, which has been thus shaped or prepared, is formed into a side
wall of a box, by joining its ends, the scalloped or zigzag edge will incline inwardly
from the line of the ridge a as illustrated in Fig. 5 and as already explained
before.
Into this side wall, the piece (of cardboard) which is to form the lid or the
bottom of the box as the case may be, is inserted from within, and finds its support
upon the rib a, see Fig. 6,-partly formed for this purpose. The whole is then
placed upon a level plate, that side having the ribbed and scalloped or zigzag edge
turned downwards, which plate may, if desired, be also grooved, to correspond
with the box. After this, a die or plunger, of such a shape and size as to fill the
interior of the box, is lowered on the bottom piece, and under the pressure thereby
produced, the scalloped or zigzag edge is turned down inwardly upon the said
Lottom piece. And lastly, the press being kept heated, the material or cement
spread over the scalloped edge is made adhesive by the heat of the press, and
unites those two parts, tiz. the side and bottom piece.

page_text: The box, which is now completed, if viewed from the top, or in plan, presents
the appearance shown in Fig. 7 of the drawings, in the case of a round box, and
that which is shown in Figs. 8 and 9, in the case of a quadrilateral box with
rounded corners.
The scalloped edge of the side wall, lying upon the surface of the top, or
bottom piece of the box, owing to its shape, serves as an ornamental finishing
whilst at the same time obviating the formation of creases when the edge is being
turned over.
The process hereinabove described may be employed with particular advantage
in the manufacture of round, oval, or generally, wholly or partly curved, cardboard
boxes.
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
A process for the manufacture of round, oval or other cardboard boxes, the
main feature of which is that strips of cardboard, corresponding in length to the
outline or periphery of the box to be formed, are provided with ribs or beads,
such as a, at a distance from the edge equal to the width of the side wall of the
box to be formed, the parts b situated on either side of the said bead or rib, being
inclined downwards; the strip c, comprised between the said ribs, covered, below,
with adhesive material, and divided in the longitudinal direction by a zigzag or
undulated cut, so that when the ends are joined, each of the parts or halves severed
from each other by the said cut, are formed into a side wall, with a rib a for the
bottom piece to rest on, the scalloped or zigzag edge being pressed against the
bottom piece adheres thereto, when the box is pressed down upon a suitable bed.
