p 1932- R. J. GRUENBERG 1,876,666
METHOD OF BLANKING FOLDING BQXES Filed Sept. 10. 1929 grime/n ce;
Patented Sept. 13, 1932 RAOUL J. GRUENBERG, OF SAN FRANCISCO, CALIFORNIA METHOD OF BLANKING FOLDING BOXES Application filed September 10, 1929. Serial No. 381,552.
This invention relates to improvements in folding boxes, and more particularly to the method of blanking the same.
The principal object of the invention is to 5, increase the capacity ofthe means for cutting and scoring boxboard folding boxes.
Another object is to reduce the cost by shortening the period of production and facilitate the fabrication of folding boxes of 9 large dimensions.
' This method of production doubles the capacity of any press or bed for cutting and scoring blanks for folding boxes.
The economies and advantages, in follow- ;is ing the method in accordance with this invention, consist in properly preparing the boxboard stock before subjecting it to the machine operation of cutting and scoring, as will be hereinafter more fully described.
Other objects and advantages will appear as this description progresses.
In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be under- 25 stood that it is not limited to such form because it may be embodied in other forms. It
is also to be understood that in and by the claims following the description it is desired to cover the invention in whatsoever form it so may be embodied.
In the accompanying sheet of drawing,
Figure 1 is a plan view of a folded box blank before being cut and scorec Figure 2 is an end view of the same,
Figure 3 is a view similar to Figure 1, of the blank in the folded condition, after it has been cut and scored in the press,
Figure lis a perspective view of a cubical folding box formed in accordance with this invention.
Fig. 5 is a diagrammatic view in vertical section of a die press cutting several super-- imposed folded blanks simultaneously.
In detail the construction illustrated in the drawing comprises a rectangular blank sheet of boxboard of the desired width cut to length and folded back upon itself at the edge 1, thus reducing its length by one half, and multiplying its thickness. It is again folded back and 50 glued at the point 2. Thus folded, the blank is introduced into the conventional press wherein it is given the marginal cuts 3, 4C, 5, 6, 7,8. (See Figure 3-).
Simultaneous with the cutting the blank is scored or creased longitudinally as indicated by the dotted line 9 and transversely at 10 11. This divides the blank into the panels A, B, C, D, which form the sides of the box, when the tab is glued to the margin 2. The divided panels E, F, G, H, I, J, K, L fold inward in superimposed relation to form the ends of the box respectively, as shown in Figure 4. v
This method of forming boxes is particularly adapted to the making of very large boxes of light kraft boxboard as a substitute for wooden crates, particularly in shipping empty tin cans and bulky matter which at presentnfequires the return of the wooden crates because of the investment therein.
Such carton folding boxes of tough kraft boxboard are better adapted to protect the contents and can be produced at such a cost that they may be discarded at the destination of the shipment.
The beds of cylinder and platen presses of the largest size are usually oblong, the largest'si'zes at present practical to manufacture being about fifty-six by seventy-two inches. These dimensions represent the superficial can be out and scored thereon, under the general practice of cutting and scoring the blanks in the open unfolded condition.
It is obvious that folding the blank on its center 1, as in Figure 1, doublesthe capacity of any press of a given size to form boxes wherein the cuts, 3, a, 5, 6, 7 and 8 respectively,
and the score lines 8, 9 and 10 are in reg1s-.
try, can be made by the cutting die 12ata single operation.
Where the folding boxes do not have isometrical dimensions as illustrated, that is, wherein the cuts 3, a, 5, 6, 7, 8 would not reg ister, these cuts can be made by introducing one end of several superimposed thicknesses of blanks into the press to make those cuts, then reversing the blanks and making the cuts on the opposite end before folding the blanks at the point 1 for introduction into areaof the largest boxblank that the larger press for forming the score lines 9, 10, 11 at a single operation, which insures proper folding edges to the box to form perfect right angles at the various corners.
{m The blanks are sent to the cutting and scoring presses in the folded condition shown in Figure 1, and are fed to the press lengthwise of its bed, and crosswise to the length of the blanks. After being cut and scored,
m as shown in Figure 3, the folding box is then in a collapsed condition ready to be transported in stacks to be unfolded and filled as shown in Figure 4, at the point of use.
Light tough relatively thin kraft boxboard,
15, a new product, is distinguished from kraft paper, and the conventional boxboard, by being thinner than the boxboard and thicker than the paper. It is perfectly adapted to fabrication in accordance with this inven- II tion, since several thicknesses of blanks may be cut and scored simultaneously in conventional printing presses, or in cylinder boX- board cutting and scoring machines.
The various cuts 3 to 8 are shown as though 1 material was removed merely for clarity of illustration. In fact they are slits made with a single cutting edge against a hard wood block.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. The method of blanking folding boxes consisting of cutting and scoring a plurality of superimposed folded blanks simultane- 35 ously.
2. The method of blanking folding boxes consisting of folding the blank back upon itself and gluing the lateral edges; cutting the blank inward from its opposite ends be- 4 tween and on the line of said fold and lateral edges.
3. The method of blanking folding boxes consisting of overlapping and gluing the lateral edges of a sheet blank and folding it flat upon itself, then cutting separated panels on the opposite ends of the folded blank.
4. The method of blanking folding boxes consisting of overlapping and gluing the lat-- eral edges of a sheet blank and folding it flat upon itself, then cutting through the opposite ends of the folded blank and scoring it transversely at the inner ends of said cuts.
In testimony whereof I have hereunto set my hand this 25th day of June A. D. 1929.
