Improved Method and Apparatus for the Manufacture of Boxes or
Box Covers of Paste Board and the like.
I, JOSEF WEIL of 2 Johannesgasse, Vienna, XVIII. Austria, Pasteboard Box
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method and apparatus for the manufacture
of round boxes or box covers from paste board and the like (hereinafter referred to
as paste board).
The method consists in bending inwardly the edge (which is provided with
adhesive material) of a paste board tube or casing, and then, by means of suitable
appliances in the interior of the tube or casing, pressing a disc of paste board on to
the said inwardly bent edge..
The bending inward of the edge of the paste board casing is effected by means of
the apparatus illustrated in Fig. 1 of the accompanying drawings in which, one or
more mandrels are fixed on a rotary disc M. Each of these mandrels comprises a
tube N in which a rod e can move, the said rod e being pressed outwardly by a
spiral spring and limited in its movement by a pin m moving in slots in
the tube.
The end of the rod e which projects from the tube carries a head which is
provided on its front face with a projecting or beaded edge.
A shaft P axially aligned with respect to one of the mandrels N, is supported in.
a movable headstock Q and is caused to rotate from a second shaft (not shown.
The
in the drawing) by means of the belt pulley n and the toothed gearing pg.
shaft P can at the same time have imparted to it a longitudinal movement to or
from the mandrel N by means of the lever system rs from a treadle or in any other
suitable manner.
The end of the shaft P adjacent to the mandrel carries a presser R which is
formed with an annular groove t corresponding to the projecting edge of the
head O, and with a central pin t¹.
The casing is mounted on the mandrel so that its edge projects beyond the
head O. The said edge is then bent inwardly by the action of the rotating disc R
which is gradually moved nearer to the mandrel, Fig. 2.
It is obvious that both long tubes or casings (for making boxes) and short parts
of casings (for making covers), can be mounted upon the mandrel. Also casings of
any diameter can be rolled up, because the mandrels and the pressers are
exchangeable.
The adjusting ring w serves for fixing the tubes or casings on the mandrel and
for determining the extent to which the edge to be rolled up projects beyond the
head O of the mandrel. The pin t' situated in the centre of the disc R, penetrates
in proportion as it is moved near to the mandrel head O, into a corresponding recess
in the latter and thereby ensures the exact central position of the casing in relation
to the groove t of the disc R. The movement of the head O may be limited. by
means of rings or washers z on the rod e between the head O and the tube of the
mandrel.
In order to fix the disc M, when one of the mandrels is opposite the presser R,
there is provided in the bed plate of the machine a locking stud u which is caused
by means of a spring to enter in one of a number of recesses that are provided at
suitable points of the periphery of the disc M.
The press by means of which the disc-shaped bottoms or covers are fixed on the
rolled up ends of the casings, so as to then form the closure illustrated in Fig. 3,
may be constructed in a similar manner to the machine shown in Fig. 1; except

page_text: that the mandrels are vertical and their heads are fixed thereto or are made in one
piece with the mandrels. It is however obvious that any other press of suitable
construction may be employed for this purpose.
The bottoms which press from the inside against the bent over edge of the tube
casing are made to enter at their periphery completely into the groove in the edge
of the tube or casing, as shown in Fig. 3, and are by this means rendered very
strong.
By the method described, boxes of any length may be made, which are
characterised by the fact that their side walls appear as if made in one with the
bottom, because the inserted bottoms fit so tightly against the inwardly rolled up
edges of the casing that the division is almost imperceptible.

COMPLETE SPECIFICATION.
Improved Method and Apparatus for the Manufacture of Boxes or
Box Covers of Paste Board and the like.
I, JOSEF WEIL, of 2 Johannesgasse, Vienna, XVIII. Austria, Pasteboard Box
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 to an improved method and apparatus for the manufacture
of round boxes or box covers from paste board and the like (hereinafter referred to
as paste board).
The method consists in bending inwardly one edge or end portion of a paste
board tube or casing, and then, by means of suitable appliances inserted in the
interior of the tube or casing, pressing a disc of paste board onto the said inwardly
bent edge or end portion which is previously provided with adhesive material in a
moist state.
The bending inward of the edge of the paste board casing is effected by means
of the apparatus illustrated in Fig. 1 of the drawings filed with my Provisional
Specification.
Referring to those drawings it will be seen the apparatus comprises one or more
mandrels fixed on a rotary disc M, each mandrel being composed of a tube N
in which a rod e can move, the said rod e being pressed outwardly by a spiral
spring and being limited in its end ways movement by a pin m moving in slots
in the tube.
The end of the rode that projects from the tube, carries a head O which is
provided on its front face or end with a projecting or beaded edge.
A shaft P axially aligned with respect to one of the mandrels N, is supported in
a movable headstock Q and is caused to rotate from a second shaft (not shown in the
drawing) by means of the belt pulley n and the toothed gearing p. 1.
The shaft P
can at the same time have imparted to it a longitudinal movement towards or from
the mandrel N by means of the arrangement of levers from a treadle, or in any
other suitable manner.
The end of the shaft P adjacent to the mandrel, carries a presser R which is
formed with an annular groove t corresponding to the projecting edge of the head O,
and with a central pin t¹.
The pasteboard casing is mounted on the mandrel so that its edge projects
beyond the head O. The said edge is then bent inwardly as shown in Fig. 2 by
the action thereon of the rotating disc R which is gradually moved nearer to the
.mandrel.
It is obvious that both long tubes or casings (for-making boxes) and short parts
of casings (for making covers) can be mounted upon the mandrel. Also that casinga

page_text: of various diameters can be rolled up, the mandrels and the pressers being made
exchangeable.
w is an adjustable ring that serves for fixing the tubes or casings endways on
the mandrel and for determining the extent to which the edge to be rolled up shall
project beyond the head O of the mandrel. The pin t' situated in the centre of
the disc R, penetrates in proportion as it is moved near to the mandrel head O,
into a corresponding recess in the latter and thereby ensures the exact central
position of the casing in relation to the groove t of the disc R. The inward move-
iment of the head O may be limited by means of rings or washers placed on the
rod e between the head O and the outer end of tube.N.
It will be understood that the disc M which is rotatable is provided with a
number of mandrels which latter can be successively brought into alignment with
the shaft P.
In order to fix the disc M, when one of the mandrels is opposite the presser R,
there is provided in the bed plate of the machine a locking stud u which is caused
by means of a spring to enter one of a number of recesses formed at suitable
points in the periphery of the disc M.
ע
The press by means of, which the disc-shaped bottoms or covers are fixed on the
rolled up ends of the casings, so as to then form the closure illustrated in Fig. 3,
may be constructed in a similar manner to the machine shown in Fig. 1, except that
the mandrels are arranged vertically and their heads are fixed thereto or are inade
in one piece therewith. It is however obvious that any other press of suitable
construction may be employed for this purpose.
The bottoms which press from the inside against the bent over edge of the
tube casing are made to enter at their periphery completely into the groove in
the edge of the tube or casing, as shown in Fig. 3 and are by this means rendered
very strong.
By the method described, boxes of any desired length may be made, the side walls
of such boxes appearing as if made in one with the bottom because the inserted
bottoms fit so tightly against the inwardly rolled up edge of the casing that the
division will be almost imperceptible.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1. The herein described method of manufacturing round boxes and box covers of
pasteboard and the like, according to which one edge or end portion of a tube or
case of pasteboard or like material is bent inwardly and in the form of a bulge over
a mandrel by means of a rotary presser and is then connected by pressure with a
disc-shaped piece of card-board or like material to form the bottom of the box or
the top of the box cover as the case may be.
2. For manufacturing round boxes and box covers of the kind referred to in
the preceding claim, apparatus comprising one or more mandrels N, fixed to a
rotary disc M, and each provided with an elastically supported head O formed with
a bulge or bead at its front end and a rotary axially movable presser R having a
groove formed to correspond to the bulge or bead on the head O and opposite which
the mandrel or each mandrel, when there are more than one, can be brought
substantially as described.
