WO LEONARD GUNN of Victoria Mills Bath in the County of Somerset Miller and
EDWARD RICE of 7 Fairlawn Avenue, Acton Green, Chiswick in the County of
Middlesex, Traveller do hereby declare the nature of this invention to be as
follows:-
This invention relates to the-preparation of cardboard or other like materials for
manufacture of boxes or receptacles or other like purposes, and has reference to
apparatus whereby the cardboard or like material may be scored or indented, cut and
printed at one and the same time in one operation.
According to one mode of carrying out this invention, the scoring or indenting
is effected by means of pieces of steel or other suitable material (hereinafter termed
the "scorers") carried on a metal or other travelling platform between which and a
revolving pressing drum or roller the cardboard or like material to be operated on is
conducted. Between the "scorers" type is inserted, and at convenient points knives
or cutters are placed so that the scoring or indenting, printing and cutting may be
performed at one operation. Or the travelling platform may be left with a flat
surface, and the "scorers," the knives or cutters, and the type be placed on the revolving
drum or roller. Or two revolving drums or rollers may be used, the one plain and
the other provided with the "scorers," knives or cutters and type, the cardboard or
like material being passed between the two under pressure. Or the scorers with or
without the knives or cutters or the type may be placed on one revolving drum
or roller and the remainder of these operating instruments may be placed on the
other revolving drum or roller or on the travelling platform. When desired, as for
example if deep scores are required, heat may be applied either to the travelling plat-
form or to the revolving drum or roller working in relation thereto, or to both the
travelling platform and the revolving drum or roller, or, where two drums or rollers
are used as a substitute for the platform and drum or roller, heat may be applied to.
either one or both of the drums or rollers.

page_text: Although we have described the scoring or indenting, cutting and printing as
accomplished by one and the same operation, yet it is obvious that either the scoring
or indenting (that is the making of all the scores) may be performed in one operation,
or the scoring or indenting and cutting may together be performed in one operation,
or the scoring or indenting, cutting and printing may be so performed, as herein-
before described.

or other like Materials for the Manufacture of Boxes or
Receptacles or other like Purposes.
We, LEONARD GUNN of Victoria Mills, Bath in the County of Somerset, Miller,
and EDWARD RICE, of 7 Fairlawn Avenue, Acton Green, Chiswick in the County
of Middlesex, Traveller, 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 the preparation of cardboard or other like materials for
the manufacture of boxes or receptacles or other like purposes and has reference to
apparatus whereby the cardboard or like material may be scored or indented,
ent and printed in one operation, as we shall describe referring to the accompanying
drawings.
Fig. 1 is a perspective view of one form of cardboard box. Fig. 2 represents a
sheet of cardboard cut and scored or indented in the places suitable for its being
folded to form two such boxes when it is cut along the line to wo, and the parts
aro folded along the dotted lines showing the scores, so as to bring the edges ¹³
together with overlap at their junction Fig. 2 represents a sheet cut and scored
to form a shallow open box.
Fig. 3 is a section of part of a cylinder printing machine with appliances
according to our invention for effecting the cutting and scoring as well as the
printing, if required, of the sheets of cardboard. Fig. 3 shews a modification of
the same. Referring to Fig. 3 which shows part of a cylinder printing machine
having an impression cylinder A and forme table B, according to one mode of
operating, we include in the type forme f rules d and e some of them blunt on the
edge to operate for merely scorring or indenting, and others of them sharp edged to
cut through the sheet g where required. The parts of the forme may be types or
design blocks for printing the sheet g at the same time as the indenting and cutting
aro performed by the rules d and e, or when printing is not required, the parts f
may be merely blank blocks or leads. In case of the apparatus being used for
printing as well as for indenting and cutting, the indenting rules when they are in
the forine, become inked, and the scores therefore appear black or coloured which may
be objectionable. In order to avoid this objection, instead of setting up the indenting
rules in the forme, we fix then on the cylinder as-indicated at a carrying them on
strips of steel or other flexible metal which are bent round the cylinder being held
at one end by clips c and at the other by tightening screws cl. We also provide on
As some of the
the cylinder strips of steel in such positions as to face the knives e.
lines of cut and indentation may be parallel to the axis of the cylinder while some
may be transverse, the strips of steel necessarily follow similar lines, and therefore
they may be most conveniently made all in one piece of thin sheet metal, resembling
a frisket, bent round the cylindrical surface, the parts between the strips being cut out

page_text: if necessary to present portions of blanket. As cardboard, however, can generally be
printed without requiring a blanket on the cylinder, the cutting out of the frisket
sheet is generally unnecessary. In order to avoid all inking of the cardboard along
the lines of indentation, the arrangement shewn by Fig. 3 may be adopted. In
this case the cylinder A having on it the strips or sheet with the indenting rules a
projecting from it has pressed against it a roller & so that the indentation of the sheet g
is effected before it reaches the forme on the table B.
In order to adjust the pressure of the roller d, its axis may be fitted to revolve
in an eccentric bearing in the bracket C, this bearing having attached to it a loaded
lever supported on an adjusting screw t.
Although we have shewn, by way of illustration, our invention applied to a common
type of printing machine such as is employed for lithographic and letter press printing,
the apparatus which we have described may obviously be applied to printing machines
of other types, such as for instance those in which the sheet passes between a forme
cylinder and an impression cylinder both the cutting and the indenting rules being
set up with the type or only the cutting rules being in the forme while the indenting
rules are on the impression cylinder.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed we declare that what we claim is :-
1. In preparing cardboard and other like materials for the manufacture of
boxes or receptacles or other-like purposes,. effecting the scoring or indenting, and
the cutting of the sheets at one printing operation, substantially as described...
1
2. In combination with a printing forme, blunt edged rules for indenting and
sharp edged rules for cutting cardboard or like sheets while they are subjected to
impression, substantially as and for the purpose set forth.
3. In combination with a printing forine and impression cylinder, sharp edged
cutting rales in the forme and blunt edged indenting rules on the cylinder, arranged
to, operate, substantially as and for the purpose set forth.
