This invention relates to an improvement in
box-making machinery and more particularly to
a machine for applying a paper cover to a blank
of shell material for the manufacture of a set-up
5
blank box.
'
Heretofore, in the manufacture of covered
boxes, it has been di?icult to obtain proper regis
rial and cover paper blanks;

rial blank, as a result of which the cover paper

tions of the suction roll;

Fig. 6 is a perspective view of the shell mate
on the box was not always positioned accurately
and uniformly. Furthermore, when the cover
paper is applied to the ?at blank of shell material,
the bending of the blank to form the box causes
the cover paper to be drawn around the edges
of the box so as to leave exposed on the interior
of the box adjacent the edges of the cover paper,
lines of adhesive which are objectionable 'and
unsightly.

Fig. 9 is a. detail perspective view of an end of

'
In Fig. 1, I have shown my invention applied
to a portion of a box-making machine of usual
or desired form, wherein shell material blanks 15
cut to proper shape ready to be set-up to form
completed boxes are fed to the forming mecha
nism, but before being set-up, the shell material

the same time to eliminate unsightly edges of
This portion of the box-making machine is
adhesive along the inner edges of the cover shown in Fig. 1, in which stacked blanks l are
paper, so that the cover paper will be applied fed from the stack by a feeding device 2, through
and maintained on the box against displacement groups of rollers 3, which convey the blanks 25
and will present a neat and desirable appearance through the machine and after having the cover
to the box.
.
In carrying out this object of the invention, I
preferably take up a slight amount of the cover
80 paper just prior to its application to the blank
of shell material, so as to allow a slight lateral
_ stretching or' extension of the cover paper after
being applied to the blank in the course of set
ting-up the blank as will be necessary to accom
modate for the stretching of the cover paper
around thecorners and edges of the set-up box.
A suction roll is used preferably in order to form
a plurality of longitudinal grooves in the cover
paper just prior and during its application to the
40 blank of shell material, which grooves are only
paper sheets applied thereto, convey the com
pleted blanks to the box setting-up machine or
device.
.
'
'
A stack of cover paper sheets 4 is arranged so 30
that the sheets may be withdrawn by a suction
feeding device 5, which transfers the sheets in
dividually to a cylinder 6, and through feeding
rolls 1 to a gluing roll 8 which spreads adhesive
over the surfaces. of the sheets of cover paper,
after which the sheets are picked up by a suction
roll or cylinder 9 which constitutes the principal
feature of the present invention and conveys
them into contact with the blanks of shell mate
rial I. A roller l 0 cooperates with the roll-or cyl
temporarily formed and of such su?lcient depth inder 9 for pressing the shell material blank and
cover sheet together.

_As shown in Fig. 3, the ?anges l3 have a semi
circular depression or groove 20, in the periphery
This is shown in Figs. 6 to 9, in which the
blanks are assembled, the sheet material blanks

rings H. "The depression or groove 20 communi
cates through. radial bores 2|, with the hollow
temporarily formed in the cover paper sheet I,
are designated 17, being intermediate the width
shaft II, in order to have suction or vacuum ap
plied to the depression or groove 20. Preferably
10 the opposite ends of the hollow shaft H are re
> spectively connected through pipes 22 with suc
of the cover paper sheet, so as to allow expan
sion thereof in setting-up the box after the edges
of the cover paper sheet 4 have been adhesively 10
secured to the shell material blank I, as shown in
tion motors 23. This arrangement "permits the Fig. 8.
This retains the cover sheet in the proper and
use of very small suction motors to supply the
, desired relation in the finished box and eliminates
needed amount of suction for the cylinder.
The opposite edges of the depression‘or groove glue lines along the inner edges of the cover 15
15
20 are closed by' sectional blades 24, shown in
detail in Fig. ‘5, which blades 24 are seated in lon
gitudinal recesses 25, in the cylindrical ?anges I3,
and are normally pressed outwardly by springs 26
20 in order to seal the opposite edges of the‘ depres
sion or groove 20 between the ?anges l3 and the
cylindrical rings l'l.
_
e
In a like manner, sectional rings 21 are used
at the opposite ends of the depression or groove
20, and are mounted in circumferential grooves,
21' at the outermost‘ ends of the cylindrical
?anges I3 and these rings 21 are likewise spring
pressed, so as to maintain the suction or vacuum
within the depression or groove 20. The 'cylin
30 drical rings I‘! are perforated, as at 28 ‘(see Figs.
3'and 4) to register with two sets of perforations
. 29 and 30, in the perforated cylinder plate I8.
'Iv'he'perforations 30 are located in the bottoms
of peripheral grooves 3|, in the cylinder plate l8. .
35 I have shown two pairs of peripheral grooves 3|
1 but the number of grooves and the width thereof
may be varied, as desired.
Referring to Fig. 1, a sheet of cover paper, after
having the glue or adhesive applied by the roll
40 8, passes under thelower edge of the suction roll
or cylinder 9. The suction m'otors 23 are op
erated su?lciently so as to maintain a constant
suction or vacuum in the depression 20 and the
machine is so timed that the cylinder plates l8'
45 and I9 are rotated relative to the‘?anges l3 and
shaft II by power applied, for instance, to one of
the end heads ‘It to bring the forward edge of
the perforations in the plate l8 over the forward
edge of the sheet of cover paper after the latter
50 passes over the gluing roll 8, which picks up the
sheet on the cylinder and conveys it around to
' the upper‘side thereof, as represented in'Fig. l,
sheet in the set-up box as resulted heretofore and
which glue lines present an unsightly appearance
to the box.
-
The box blank is completed by folding in the
sides and by adhesively securing the corners of 20
the cover sheet to the end wings, as shown in
Fig. 9, which represents the completed blank
for the box ready for opening up.
This provides a great improvement in the box
construction over covered boxes ‘which have been 25
made heretofore.
'
- At the time of infolding of the side wings of the
blank _ the glue of the cover» sheet has not set
?rmly, and will give suf?cientlyto allow lateral
expansion of the cover sheet to accommodate for 30
the folding '- of the corners of the blank, after
which pressure may be applied to the blank to
set the glue.
I claim:
-

2. In the art of making covered box blanks,
the steps of adhesively applying cover material
