‘
The manner of forming the gussets may be as
follows. (Referring to Figs. 1 and 9, i1 indicates
part of any ordinary press or carton blank form
ing machine, which carries knife elements and
scoring elements I! and i9, respectively, properly
arranged to blank out the carton of Fig. 'l and
to provide the various scores 20 and slits 2|.
The machine in general may be of any approved
type, and it ordinarily includes a reciprocating
bed 22 adapted to carry one or more frames 23
in which are clamped a series of carton blanking
units comprising the scoring means and cutters
above referred to. In practice, a large sheet of
cardboard or paper is fed onto the frame to
overlie the elements i8 and i8, and ‘this sheet'
moves, with the bed and frame, beneath a pres
sure means 24 which forces the sheet against the
cutters and scoring elements to provide the blank
disclosed in Fig. 7.
Particular attention is directed to the trans
verse cutters or blades II which provide the slits
2| of Fig. 7. It will be noted that each blade is
ground or shaped at one end, as at 25, to slope
toward the major axis of the blade, so that any
slit 2| formed by the blade will be incomplete at
the adjacent longitudinal score 20, especially as
corners against entry of moisture, air, etc. The
_ cardboard or paper stock for the cartons or con
taines is invariably made up of thin layes of
paper, wherefore the gussets when formed are
constituted of a de?nite amount of stock deter
mined by the shape of the blade ends 25 and the
depth of the cut with which such blades enter
the stock. The blades therefore must be properly
adjused, as to height, within the frame 23 of
Fig. 1, or else the compressive force of. roll 2|
should be varied to secure the result above set
forth.
The various steps of the method of forming
the cartons is as follows: After setting up the
machine of Fig. 1 to effect the proper scoring,
cutting and blanking out operations, the table
with a sheet of cardboard thereon is reciprocated
relative to the compression means 24, whereby
to produce the various scores and incomplete 30
slits shown in Fig. 7. The blank thus formed is
then glued along its extended glue ‘flap 28 and
shaped into a rectangular open ended tube with
said ?ap glued to the wall 29. Thereafter, the
bottom~forming ?aps are bent along their score
lines, providing gussets as explained, and secured
to one another to close the bottom of the con
talner. The next operation is the ?lling and
