PROVISIONAL SPECIFICATION.
Apparatus for Making Cases of Cardboard or other Material
to Receive Packets or Boxes Containing Cigarettes or other
Articles.
We, RICHARD DALTON of Nansloe, Carnarvon Road, Redland, Bristol,
Commercial Traveller and HEBER MARDON of the Firm of Mardon Son and
Hall of Caxton Works, Bristol, Manufacturing Stationers, do hereby declare
the nature of this invention to he as follows:-
The object of this invention is to construct a simple apparatus for the rapid,
efficient and economical manufacture from cardboard or other material, of cases,
and more particularly open ended cases such as are employed to receive packets or
boxes containing cigarettes or other articles.
The novel apparatus for this purpose comprises a roller and a set of scoring
discs or knives for scoring the blanks of cardboard or other material along lines
on which they are afterwards to be folded so as to form the corners of the
completed case; devices for feeding the blanks to the roller and scoring discs ;
devices for conveying the blanks after having been scored to turning up, folding,
pasting and pressing devices; a helix or other form of turner (preferably fixed)
for turning up a scored blank at right angles along the scored line nearest to one
of its side edges; a device for applying gum or paste to the underside of the blank
near the other side edge; a second helix or turner for turning up the blank on
the line of one of its middle scores and folding it over close upon the rest of the
blank the edge of the gummed part entering the angle formed by the first turned
up portion; a third helix or turner for turning down this first turned up portion
upon the gummed part of the blank; and one or more sets of pressing devices for
pressing the folded blank along the line of its gummed joint.
In carrying out the invention the blanks may be placed automatically or by
band on a feed table from which they may be fed by a lever and shuttle or by a
wheel with projections or by other suitable means between the roller and the
scoring discs or knives. The roller rotates and thereby causes each blank to pass
through between it and the discs. The scored blank may be allowed to drop on
to supports from which it may be conveyed by arms or otherwise to the turning
up, folding and pasting table along which it is conveyed preferably by carriers on
an endless band. During its travel along this table the blank comes under the
action of the first turner, then or simultaneously or previously under the action of
the gumming or pasting device which may conveniently consist of a gum wheel
projecting slightly through the table; then under the action of the second and
third turners successively; then to the first set of pressing devices which may
conveniently consist of a pair of endless band wheels and then if thought desirable
to a second similar pair of pressing devices. The folded, gummed and pressed
blank is delivered to a suitable receptacle or may be first subjected to a drying
process. The blank is now a complete case but pressed flat with its sides close
together, but a slight pressure between the finger and thumb on opposite corners
brings it to its correct finished shape as a rectangular case.
The apparatus may be constructed either with one set of appliances as above

page_text: described or with two or more sets so as to act simultaneously upon two or more
supplies of blanks.

Apparatus for Making Cases of Cardboard or other Material
to Receive Packets or Boxes Containing Cigarettes or other
Articles.
We, RICHARD DALTON of Nansloe, Carnarvon Road, Redland, Bristol,
Commercial Traveller, and HEBER MARDON of the Firm of Mardon Son and
Hall of Caxton Works, Bristol,. Manufacturing Stationers, 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-
The object of this invention is to construct a simple machine or apparatus for
the rapid, efficient and economical manufacture from cardboard or other material,
of cases, and more particularly cases open at both ends such as are employed to
receive packets or boxes containing cigarettes or other articles.
The novel machine or apparatus for this purpose comprises a roller and a set of
scoring discs or knives for scoring the blanks of cardboard or other material along
lines on which they are afterwards to be folded so as to form the corners of the
completed case; devices for conveying the blanks after having been scored to
turning up, folding pasting and pressing devices; a helical or other shaped turner
(preferably fixed) for turning up a scored blank at right angles along the scored
line nearest to one of its side edges; a device for applying then, or simultaneously
therewith, or previously thereto, gum or paste to the underside of the blank near
the other side edge; a second helical turner for turning up the blank on the line
of one of its middle scores and folding it over close upon the rest of the blank the
edge of the gummed part entering the angle formed by the first turned up portion;
a third helical turner for turning down this first turned up portion upon the
gummed part of the blank; and one or more sets of pressing devices for pressing
the folded blank along the line of its gummed joint.
Figures 1, 2, and 3 of the accompanying illustrative drawings illustrate one
arrangement of machine or apparatus constructed in accordance with this
invention;
Figure 1 being a side elevation of the entire machine; Figure 2 a plan view of the
same; and Figure 3 a vertical cross section on the line 3-3 of Figures 1
and 2, looking from the feeding end A towards the delivery end B of the
machine.
Figure 4 is a side clevation illustrating the general arrangement of a modified
form of the machine.
Figures 5, 5, 5B, 5°, are diagrammatic end views illustrating the successional
folding of a scored cardboard strip along the scores the depth of the latter being
shown exaggerated.
Figure 6 is a perspective end view of the finished case.
In all these figures similar reference letters and numerals serve to indicate the
same parts.
The arrangement of machine illustrated by Figures 1, 2 and 3 is especially
designed for the manufacture of cardboard cases open at both ends from strips of
cardboard, fed in 'succession into the machine, each strip being of a length

page_text: sufficient to form one long case or a number of short cases. Each strip is formed
by the machine into a long continuous case which is of the same length as the
strip and is delivered from the machine in a flattened state. This flattened case
can then be cut up into a number of lengths each of which can be readily opened
by hand or otherwise so as to coustitute a finished cardboard case of the desired
length open at both ends.
For the purpose of enabling the nature of our invention to be more readily
understood, we shall now proceed to describe the arrangement and mode of
operation of the several devices in the order of their position, starting from
the feeding end A of the machine, and following the travel of the cardboard
strip through the machine in its conversion into a flattened case as above
imentioned.
1
Referring to Figures 1, 2 and 3, A is the feeding end and B is the delivery end
of the machine table 1 which is formed by the smooth flat upper surface of a
girder or box shaped casting 2 supported on standards 3. In the table I is formed
a central opening 1 extending the whole length of the table to allow of the
operation of the requisite belts, wheels, rollers and other parts hereinafter
described.
Adjustable guide pieces or fillets 1, 1 are arranged at suitable points parallel
to the line of travel of the cardboard strips for the purpose of keeping the latter
straight. The flat cardboard strip having a width equal to twice the width plus
three times the depth of the finished case is fed in by hand at the end A, under
the scoring discs 41, 42, 43, 4 which are four in number and are adapted to produce
the respective scores a, b, c, d (Figure 5) in the cardboard; they are mounted on
two parallel spindles carried in brackets 5 bolted to the table. The two inner
scoring discs 43, 43 are arranged one on each side of the longitudinal centre line of
the table at a distance apart equal to the depth of the finished case. Each of the
other two discs 4', 4 is arranged at a distance away from the nearest inner disc
equal to the width of the finished case. The pressure of the scoring discs upon
the cardboard strip is taken up by a live roller 6 mounted under the scoring discs.
In some cases the relative positions of the scoring discs and the roller 6 may be
reversed, that is to say the discs are situated under the roller.
From the scoring discs the cardboard strip scored along four parallel
lines a, b, c, d (Figure 5) passes to the gumming device which consists of a
gumming wheel 7 arranged to revolve with its lower part dipping into gum, paste,
glue, or other suitable adhesive substance (included in the term gum) contained
in a receptacle 8. The gumming wheel 7 is arranged on the left hand side of
the table so that the top of the wheel which projects slightly above the top of the
table through a slot formed in the same, will apply a stripe of gum to the under-
side of the left hand portion of the cardboard strip which is situated outside of
the score d produced by the scoring disc 4. A pressure roller 9 serves to press
the cardboard strip down upon the gumming wheel. The gumming wheel 7 is
conveniently driven by means of a pulley 7, strap 7 and pulley from the
scoring roller shaft.
Behind the gumming wheel 7 and mounted below the table is a wheel 10 around
which passes an endless travelling band or band conveyor 11 the upper stretch of
which extends horizontally from this point onward flush with the top of the table
towards the delivery end of the latter. This endless band 11 assists in conveying
the cardboard strip through the succeeding devices to be described. A pressure
roller 10' supported in brackets bolted to the table serves to nip the cardboard
strip between it and the endless band 11.
By this means the cardboard strip with its gummed edge portion is conveyed to
the first helical turner 12 which is arranged on the right hand side of the endless
band 11 close up to the point of the delivery roller 10'. This first helical turner 12
consists of a part bolted to the table and formed with a helical surface, extending
longitudinally of and facing the endless band 11. This turner has for object to
gradually turn or bend that portion of the cardboard strip which lies outside of

page_text: the right hand outer score a produced by the scoring disc 4', up at right angles to
the remaining or horizontal part of the strip as shown in Figure 5. Immediately
behind or as shown facing the first helical turner 12 but on the left hand or opposite
side of the endless belt with its helical surface facing the latter is the second
helical turner 13 which has for object to turn up or bend in a gradual manner all
that portion of the cardboard strip situated outside of the left hand inner score c
produced by the scoring disc 43 and to further turn said portion down flat upon
the remaining central horizontal portion of the strip as shown in the Figure 5".
The said central or horizontal portion of the cardboard strip is kept from rising
and the bending of the cardboard is ensured along the proper scores by means of
a central adjustable guide piece 14 (Figure 3) which is fixed by its upper end to
a bridge piece 15 bolted to the table and extends down just short of the table by
an amount slightly greater than the thickness of the cardboard strip.
A guide roller may be employed instead of the guide piece 14 shown.
The helical turners 12 and 13 deliver the strip into a straight-sided channel 16
which is fixed to the table and extends past à pair of rollers 17, 171 the upper
one 17 of which serves to nip the horizontal portion of the cardboard strip upon
the endless band 11 which is supported at this point by the lower roller 17. The
straight sided channel 16 delivers the strip into the third helical turner 18 which
is situated on the right hand side of the endless band 11 with its helical surface
facing the latter and which serves to turn the upright right hand portion that was
turned up by the first helical turner, down flat on to the gummed and now uppermost
surface of the portion that was turned down by the second helical turner as shown
in Figure 5. During this operation the folded blank is kept flat by the pressure
of an upper roller 191 exerted upon a lower roller 19 that serves to support the
endless band 11 at this point. From the third helical turner 18 the folded blank
is carried by the endless band 11 between a pair of pressing rollers 20, 20', which
serve to press the folded blank more firmly together along the line of its gummed
joint. A further pressing device consisting of a lower wheel 21 and of an upper
pressing roller 21 serves to effect a final consolidation of the gummed joint of the
folded blank which then issues at the delivery end B of the machine in the form
of a long flattened case which can then be cut up into lengths each of which
forms a complete case, pressed flat with its sides close together; but a slight
pressure between the finger and thumb on opposite corners brings it to its correct
finished shape as a rectangular case shown in Figure 6.
Additional guidance is afforded to the blank in its travel from the roller 20, 20¹
to the rollers 21, 21 by means of an endless band 22 passing round the upper
rollers 20, 211 the blank being thus nipped between the two endless bands 11
and 22. The endless band 11 passes round the driving band wheel 21 and the
driven band wheel 10 and its upper length is supported by the intermediately
situated rollers 20, 19 and 17.
It is to be understood that the turners and their corresponding guide pieces and
rollers are mounted in such a manner as to allow of adjusting the same to suit
blanks or strips of different widths.
Motive power is supplied by means of a belt 23 and fast and loose belt
pulleys 24, 24 mounted on the driving shaft 25 of the machine. A toothed
wheel 26 keyed on the shaft 25 drives through an intermediate toothed wheel 27
a toothed wheel 28 keyed on the shaft 29 of the band wheel 21.
Upon the driving shaft 25 is keyed a chain wheel 30 around which passes a pitch
chain 31 which passes over and serves to drive the chain wheel 20 and 6" keyed
on the axles of the rollers 20, and 6 respectively. A guide pulley 32 is provided
to keep the chain 31 up in engagement with the driving chain wheel 30.
The modified apparatus illustrated in Figure 4 is designed to score and fold
blanks or strips which are not long enough to reach from one rotary propelling
part of the apparatus to the next and in which therefore supplementary carriers
are required, as will be the case for example when each cardboard strip is only of
the length required to form one complete cardboard case of comparatively short

page_text: length. In the modified arrangement of apparatus, the gumming wheel 7 is driven
by means of a pulley 33, belt 34 and pulley 35 from the driving shaft 25; it is
arranged on the left hand side of the table 1 opposite to the first helical turner 12.
The second helical turner 13 is situated behind the first helical turner 12 but on
the opposite side to the latter, whilst the third helical turner 18 is situated behind,
but on the opposite side to the second helical turner. The straight-sided guide
piece or channel 16 of the arrangement shown in Figures 1, 2 and 3 is dispensed
with, the three helical turners being arranged to overlap one another, that is to
say before the cardboard strip leaves the first helical turner, it is engaged by the
second helical turner, and before it has left the latter it is engaged by the third
helical turner. Each turner is provided with a corresponding guide piece or
roller not shown. The several blanks or strips are fed by hand at A under the
scoring discs whence the blanks are conveyed by the lower portion of an endless
band 36 passing over rollers 37 and 38 (the latter being driven by means of a chain
wheel 38 from the pitch chain 31) on to an endless carrier band 11ª which is
provided with carriers 11 and is driven by means of the belt wheels 10 and 21º.
The carriers 11 which are arranged in pairs abreast project through longitudinal
slots in the table 1 and serve to convey the blanks past the gumming device 7,
the first second and third helical turners 12, 13 and 18, and the first pair of
pressing rollers 20, 20¹. From these the folded gummed and pressed blanks are
carried to the final pressing rollers 21, 21, by means of the adjacent.parallel
portions of the endless bands 20 and 20** passing around the respective pairs of
rollers 20, 21 and 20, 21'. The final pressing rollers 21* 21' deliver each flat
folded gummed and pressed cardboard blank on to the delivery end B of the table 1,
ready to be pressed by hand into the finished form of the required cardboard
case.
In both the arrangements of apparatus shown in Figures 1, 2 and 3 and Figure 4
the friction of the cardboard strips in moving along and being bent or turned by
the helical turners, may be reduced if desired by providing antifriction rollers
arranged tangentially to the helical surfaces at the respective points.
The apparatus may be constructed with one set of appliances as above described
and shown or with two or more sets so as to act simultaneously upon two or more
supplies of blanks.
Having now particularly described and ascertained the nature of our said.
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In apparatus for making open ended cases of the kind herein referred to, the
combination of a set of discs or knives for scoring the blanks, a gumming or
pasting device and a series of turners for turning and folding the blanks along the
scored lines, substantially as and for the purpose herein before described.
2. The use of turners of helical form substantially as and for the purpose set
forth.
3. Constructing apparatus arranged and operating substantially as hereinbefore
described and represented in Figures 1, 2 and 3.
