COMPLETE SPECIFICATION.
An Improved Machine for Cutting Out or Printing and Cutting Out
Simultaneously Blanks of Paper, Cardboard, Leather, or other
Sheet Material for the Manufacture of Boxes, or other like
purposes.
I, PAUL AUGUSTE-GODCHAUX of 10 Rue de la Douane, Paris in the Republic of
France, 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 has for its object a rotary machine for cutting out blanks which
I have combined with the system of rotary printing machines forming the object
of my Patents, Nos. 52200, 7935 and 423093 of the 4th Oct. 1889, 8th May 1891
and 27th Feb. 1893, respectively.
In order to make boxes such as are used in commerce (more particularly for the
sale of lump sugar) sheets of stout paper, or cardboard are first printed (the
impression comprising the name of the vendor or the manufacturer, the kind of
product, its price, etcetera, etcetera) and they are then cut out by hand or
mechanically.
On the accompanying drawings:-
1
Figure 1 represents a blank of cardboard, the corners a and b of which have
been removed, and which has at certain places 6 straight or oblique cuts c d e f g h
Figure 2 shows a blank of cardboard cut out with a rectilinear and curved
profile. It is also cut on the lines i j k.
Figure 3 shows a blank of cardboard for boxes cut out with a partly rectilinear
and partly curved profile. This blank has also elliptical perforations l m n o.
Figure 4 represents a blank of cardboard of another form.
The four variously shaped pieces of card or paper shown by Figures 1 to 4, may
be cut out with my improved machine at the same time as they are printed, but it
will be readily understood that these are only simple examples because I can cut
out with my machine any kind of blank whatever may be its form and dimensions.
Figure 5 is a side view of the complete machine employed for cutting out such
blanks.
Figure 6 is a view of the cutter on the rollers, and
Figure 7 is an end view of the rollers.
My machine for cutting out blanks comprises two cylinders A and B mounted on
a frame C. The cylinder A is provided with several knives suitable for cutting
out. The cylinder B forms the counterpart.
The
The knife blades on the cylinder A are arranged on the cylinder so as to follow
either the genetrix of the cylinder or circles whose planes are perpendicular to its
axis, or oblique lines or any suitable elliptical curves (see Figure 6). The shape
of the knife varies according to the blank which it is desired to obtain.
knives may be formed of simple straight blades, or may even have an entirely
closed contour such as p, Figure 6, in which latter case they constitute a veritable
punch, or their contour may even be not completely closed such as shown at 9,
Figure 6.
In the interior of the cutting knives, I place springs of any suitable kind in
order to push the blank to the outside when it is cut out.

The cutting blades may be fixed.on the cylinder A by any suitable means.
cylinder B forming the counterpart is preferably of cast metal but it may also be
of any other suitable material.
The cutting blades are set in such a way as to bear exactly on the cylinder B,
and two cheeks or flanges D D serve to adjust the contact between the said cutting
blades and the cylinder B in such a way as to avoid any breakage.
The cutting out apparatus which I have just described is combined with the
printing machine described in my Patent of the 27th February 1893, and which
forms the object of my other previous Patents, by means of three cog wheels or the
like gearing E, F, G.
The wheel E is keyed on the shaft of the cylinder A, F is loose and G is keyed
on the shaft of the printing cylinder or that of the impression cylinder of the
rotary printing machine. The wheels E, F, G have precisely the same number
of teeth, so that the cylinder A has precisely the same speed as the printing
cylinder of the printing machine. The number of wheels connecting the cutter-
out with the printing machine may be more or less in number but should always
have precisely the same number of teeth.
The material coming printed from the printing machine arrives at L and from
there passes over the cylinder B, being pressed and guided against the latter by
rollers N which are adjustable so that they may be more or less approached to or
removed from the cylinder B. In passing between the two cylinders A and B the
material is cut out on the lines desired by the cutting blades of the cylinder A.
From there the cut out blanks pass between the rollers H and I and fall onto
endless bands J supported on rollers K around which they revolve, the said bands
conveying the blanks on to the table M on which they are collected.
The cutting out machine shown in Figure 5 may be combined with one or other
of the printing machines previously patented by me. As the cylinder A has
always exactly the same speed as the printing cylinder, the justification is always
absolutely perfect; as I have explained in previous Patents. With the machine
which I have just described I can not only cut out papers or cardboards of all
forms and dimensions but also any other kind of sheet material such as leather and
the like.
I have mentioned herein before that the cutting out machine is connected with a
printing machine on my system, but it is evident that I can combine my cutting out
machine with a printing machine of any other description. I can even use the
cutting out machine alone, when it is not required to print the sheets which are to
be cut out or when they are already printed. I can, as I have already stated, with
my machine cut out sheets or plates of any shape and dimensions and according to
any desired profile.
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. An improved machine for cutting out blanks, consisting of a cylinder A
carrying knives bearing exactly against a counterpart cylinder B, preferably of
cast metal, the said cylinders having a rotary metion one against the other
substantially as described and illustrated.
2. An improved apparatus for printing and cutting out blanks, comprising the
cutting out machine described in Claim 1 in combination with a rotary printing
machine connected therewith by means of gearing having an equal number of teeth,
substantially as described.
