A means 26 is provided for manipulating a partition

A ?nger 36 is adjustably secured to the shaft 34 at a

shown more clearly in FiGURE 2, one end of the spring

end of the spring 44 is ?xedly secured to the bearing

It is another object of the present invention to provide
a novel apparatus for manipulating a partition wall out
of the plane of a side wall of a carton and disposing
the same in a position extending between the side walls
of the carton.
t is another object of the present invention to provide a
novel apparatus which is capable of cooperating with car
tons as they proceed along a conveyor belt so as to auto
matically provide the cartons with a partition wall.
It is still another object of the present invention to pro
vide an apparatus which is simple and economical while
capable of materially reducing the cost of a partition wall
for a carton and materially increasing the rate at which
such cartons may be ?lled with material.
Other objects will appear hereinafter.
For the purpose of illustrating the invention there is
‘shown in the drawings a form which is presently preferred;
it being understood, however, that this invention is not
limited to the precise arrangements and instrumentalities
shown.
is provided with a >U-shaped slit. A score line 59 extends
across the free ends of the U-shaped slit at a point equi
distant from the ends of the carton 46.
The remaining elements not yet speci?cally described
are more conveniently explained in conjunction with the
manner in which the present invention is utilized.
As the cartons 46 are folded by a folding means with
in the housing 1.12, such cartons are conveyed to the out
let aperture 14 between the guide plates 16 and T.“ by the
chain 24. Suitable positioning means (not shown) may
be provided to assure that the cartons 46 are juxtaposed
to the guide plate 18 as shown more clearly in FIGURE

As the carton 46 approaches the end of the guide

and ?nger of the present invention.
As the carton 46 passes by the ?nger 36, the rounded
end of the ?nger 35 presses against the side wall 51 of
the carton 46. Since the side wall 51 is provided with

in which the ?nger cooperates therewith.

3 and 4 showing another position of the carton and the
manner in which the ?nger cooperates therewith.
FIGURE 6 is a perspective view of the carton adapted
to cooperate with the ?nger as shown in FIGURES 3-5.
Referring to the drawing in detail, wherein like nu
merals indicate like elements, there is shown in FIGURE
1 a carton folding apparatus designated generally as 10.
The apparatus 10 includes a housing 12 within which
is disposed means for folding blanks into a carton of the
type shown in FIGURE 6.
Such means forms no part
of the present invention and therefore need not be shown
or described in detail.
The housing 12 is provided with an outlet aperture 14
a uashaped slit, the ?nger 36 readily pushes the partition
wall 48 inwardly as shown more clearly in FIGURE 4.
As the partition wall 48 is moved to the position shown
in FIGURE 4, the partition wall 43 pivots about the score
line 59.
As the carton 46 continues in its movement past the
?nger 36, the portion of the wall 51 adjacent the score
line 50 contacts the ?nger and rotates the same against
the bias of the spring 4-4. That is, the ?nger 36 rotates
in a clockwise direction in FiGURES 4 and 5 until the
?nger assumes the position shown in FIGURE 5. It will
be understood that the spring 44 is weak enough so that
the wall 51 adjacent the score line St} is not torn by con
tact with the ?nger 36.
As the carton 46 continues to move under the influence
of the chain 24, the rounded end of the ?nger 36 presses
against the side wall 51 until the ?nger 36 clears the end
52 of the carton 46. Thereafter, the ?nger 36 rotates in

FIGURE 3 due to the bias of the torsion spring 44.
As shown more clearly in FIGURES 4 and 5, the move
ment of the partition" wall 48 out of‘the planeof'th'e'side
wall‘ 51 results in the provision of a rectangular aperture
541having dimensions corresponding with the dimensions
of, the partition wall 48. It‘will be noted that the length
of the partition wall 48 ‘corresponds to the distance be
tween the side walls of the carton 46. Su?cient details of
URE 2, the vertical disposition of the ?nger 36 may be
adjusted so as to accommodate di?erent sized cartons
and/or locations of the partition wall 48.
The present invention may be embodied in other spe

attributes thereof and, accordingly, reference should be
