that less than a predetermined number of cards could till
a ?xed space that would normally take the predetermined
number. In order to insure that the customer will re
ceive the number of cards he has ordered, it has been the
practice to make the cartons a little larger and ?ll the
carton with additional cards. If two thousand cards only
are counted, and in view of the varying thickness of each
card, they do not ?ll the carton, the loose ?t of the cards
results in card damage when they are transported. Since
it is important that the carton be the exact size of the
cards, either additional cards or ?llers are used to take
up the void space. In either event, whether the carton is
?lled with extra cards, or with a ?ller, the addition of
the extra cards or the ?llers, becomes quite costly. One
solution to the problem is to provide a variable length
carton, the capacity being varied by varying the length of
the carton itself.
Such an arrangement is found in ap

two-piece variable length carton is disclosed for packing

Brie?y stated and in accordance with one aspect of the
invention, a carton forming and packaging machine is pro
vided in which means are included for stacking the cards
on a movable support, which movable support is con
nected to a second support for holding a blank carton of
?xed length which is to be scored to the exact size of
the stack of cards, means are provided for depressing the
cards so as to move the support for the cards and simul
taneously move the support for the blank. When the pre
determined number of cards are positioned in the card
stack, scoring means is then activated to score the blank
at the exact height determined by the distance that both
supports have ‘been moved. In accordance with another
. aspect of the invention, a card transport mechanism is
provided to form the carton and package the cards in the
carton.
The foregoing and other objects, features and advan
tages of the invention will be apparent from the following
more particular description of a preferred embodiment
of the invention, as illustrated in the accompanying draw
ings.

However, it is recognized that any ?xed number of cards

of locking plate 16 holding it in open position.
In order to stack the cards and to restore the card
clamping mechanism to its open or receiving position,
the rods 14 and the support 13 ‘are activated in the op

underside of card support surface 47.
Referring now to FIGS. 7 and 8, a scoring and creasing
mechanism is provided. A carton blank is shown at 64
which can be fed along a channel 66 to‘ a position on a
egment 68 of the channe. The segment 68 is rigidly
connected to the support plates 44 and 46 by a U-shaped
bar 70. Since the segment 68 is rigidly connected to the
support plates, the stack and carton will descend the
same distance when the stack is operated upon by the
plunger 42.
In order to score or crease the carton, a
carton scoring unit '71 is provided and includes blocks

The channel shaped supporting members each contain an

FIG. '2, can move horizontally to pick up a stack of
cards, deposit them in the card stacking mechanism 32
and move out of the way for further operations to take
place without interference. The apertures are sufficient

conventional piston arrangement can operate the retain

the thrust of the card transporting mechanism a pair of
gates 82 and 84 are provided. The arm '76, retainer mem

In operation the card clamping mechanism 12 is moved
horizontally by activating the rods 14 and the support 13
in the direction of the arrow at 23. The clamping arm
20 is normally above the stack of cards. The stack of
cards is generally a ?xed number, and due to the variance
in thickness, each card will result in each stack of cards
being diiferent in height. Accordingly, the clamping mem

in height. Simultaneously, the locking plate 16 is dis

in FIG. 12. The carton is now positioned directly in
