METHOD OF MAKING BOXES AND BOX BLANKS.

' Methods of Making Boxes and Box Blanks,

of which the following is a specification. My invention relates to methods of applymg or inserting strings or tapes in boxes I or box-blanks.

The general object of the invention is to provide process steps which may be performed by hand, but which are well adapted for performance by machine operations, for the economical production of strung boxes or blanks on a high output basis.

It is desirable in certain classes of boxes made of paper or like materials, to provide tying strings or tapes, which are usually attached within the lower box section, for

tying in the box contents. One example of the class isshirt-waist boxes, in which such tapes are desirably provided. for securing one or more of the waists in proper condition in the box bottom;

Previous to the resent invention, box structures and manu acturing methods have not been suitable for rapid and economical attachment of these tying cords, or for ma"- chine methods of production of corded or strung boxes.

For convenience, the word cords be used hereafter as a broad designation of strings, tapes or other suitable box-contents tying materials.

In one of its variationsjthe invention is Well adapted for application of cords to covered blanks or boxes, and especially to coveredbox structures and methods of my own invention; but .the invention is by no -means limited in this respect, and an example is givenof a method well adapted for uncovered boxes. Q The characteristics of the' invention are best understoodby COIlSldGI'lDg, certain exemplifying performances of the method, de-

scribed in detail hereafter, with reference to the accompanying drawings. It will be understood that the principles thus exemplified include many possible variations, and I contemplate-any. process steps, orcombinations of them, that are properly within the scope of the appended claims.

steps of blanks.

Figs. 2 and 3 are bottom views of different portions of the blank assembly:

Fig. 4 is a perspective view of a box part (bottom section) produced from the severed blank B of Fig. 1.

Fig. 5 is a, diagrammatic view, mainly inside elevation and'partly in longitudinal section, of representative apparatus for per forming the operations indicated in Fig 1. Fig. 6 is a top plan of the same.

Fig. 7 .is a transverse diagrammaticsec 'tion of apparatus for performing a modified cord-attaching operation.

Fig. 8 is a top plan of a box-blank havproducing complete corded box ing' cords attached by themethod indicated in Fig. 8.

In the methodexemplified in Figs. 1, 2 and 3, a continuous strip S" of box-shell'material, usually cardboard of suitable quality and thickness, is moved forward and 1s creased or scored along the longitudinal l1nes 1 and transverselines 2 to facilitate subsequent folding. At a suitable point in the advance of the shell material, holes 3,of suit-' able outline, in the present case rectangular, are punched midway between each two ad a-.

cent folding lines 2. The order in which the holes are punched and the folding lines are creased or scored is not material in the broader aspect of the invention.

At a suitable point in the advance of theshell material, tying cords 4 are brought in proximity tothe'strip ofshell material, and

are fed along with it,..one of these cords being laid, desirably, substantially along each of the longitudinal folding lines 1. cords may be f any suitable material, but in this particular case they are desirably in the form of tapes of more or less loosely wovenmaterial, of the kind frequently employed for tying articles and packages where a somewhat decorative appearance is desirable; These-cords are now attached to the shell material at intervals, and in the present exemplification of the method, thisis accomplished by forcing the cords through the shell material at suitable places, such as the points 5 and 6. This forcing of the cords through the shell material is accompanied "by a perforation of the shell strip, and short bends or loops 7 (Fig. 2) are formed in the cords at the und r side of the shell strip.

The number and location-of the, points of,

attachment of each cord may be varied The" greatly, but desirably, as in the present instance, the two points of attachment are located at such a distance from adjacent apertures 3 as to provide free cord portions of the desired length for tying when the blank or box is completed, as will later appear.

When the perforating and looping method of attaching the cords is employed as above described, it is usually necessary to provide some further means forsecuring the cords at r the attachment points, and this may be done in various ways. In the present instance, a sheet of cover paper is desirably applied to the advancing continuous shell blank, for the production of covered boxes, and in the application of this covering material, the cord loops are incidentally secured.

A continuous strip C of covering material, usually paper of suitable thickness and quality for boxes of the grade desired, is advanced in proximity to the shell material,

and at a suitable point the surface of the cover strip which is to be engaged with the shell material, is rendered adhesive in any suitable way, for instance by applying adhesive 8 to the upper surface of the cover strip. The cover strip is then brought into contact with the under surface of the shell strip as the two are advanced together, and properly pressed or rolled into position; and in this operation the cord loops 7 are pressed down against the shell material and adhesively secured by the cover strip, as sufficiently shown in Fig. 3, in which a portion of the cover material about one of the loops 7 is torn away for illustrative purposes.

At a suitable vpoint in the advance of the assembled continuous blank strip consisting of shell and body material and attached cords, the outwardly extending margins 9 of the cover material are turned over and adhesively secured upon upper marginal surcomposite continuous box blank comprising shell'material covered on one surface and having its edges covered by the overturned portions of the cover strip, creased, and apertured at intervals corresponding to the length of each completed blank, the shell material covering the apertures having upwardly presented adhesive surfaces, and provided with continuous tying cords or tapes secured at intervals.

Individual blanks B, Fig. 4:, are now produced from the continuous assembly by severing the assembly strip on transverse lines 12 intersecting'the longitudinal centers of apertures 3. The box-blanks so produced have each a central or body portion 15, side wings 16, end wings 17 'with projecting, adhesively coated marginal portions 18 of the cover materiahand end or .cor-

ner laps '19. The corner laps are desirably,

from the end wings, by cutting along the.

lines 20. In the act of severing individual blanks from the continuous assembly strip,

- cords 4 are also severed, providing a free portion 25 of each cord near each end of the blank, these portions being long enough to be brought together over an article, such as a. shirt-waist, to be packed in the box section produced from the blank, and tied to hold the article properly in position. The desired length of the tying portions of the cords is obtained by properly locating the connection points 5 and 6 in relation to the ends of the individual blank.

The blank of Figure 4 is then bent up into box form as shown in Figure 5, that is, side and end wings are bent up at right angles to the. body portion 15 with the corner laps 19 bent inward against the inner faces of the end wings, and cover margins 18 are then turned in and pressed against inner faces of the corner laps and end wings, as shown at the right in Fig. 5, to secure the blank in box form. At the left in Figure 5 the cover margin 18 is shown projecting upward, ready to be turned in in the manner described. There is thus produced a. complete lbox section provided with tying cords ready to receive commodities of the class described.

igures 6 and 7 show in a diagrammatic way, representative mechanical devices for performing the described operations, up to the point of severing individual blanks from the continuous assembly, in one desirable sequence. In this exemplification. of the method, the shell material S is supplied on a roll 30, and is advanced between rolls 31 and 32, which are suitably flanged and grooved to press the longitudinal creases 1. Thereafter the shell strip passes between pressers 33 and 34, provided with a cooperating rib or blade 35 and groove 36, to press the tranverse folding creases 2. The shell strip then passes under a punch 38 operated by suitable means, such as a cam 39, and cooperating with a. punch die 40, for punching the apertures 3. Just beyond the punch, rolls or spools 45 are arranged in convenient positions above the shell strip, supporting the cords or tapes 4, and'these cords are guided into engagement with the shell strip by rolls or pulleys 46. Any suitable tensioning devices may be applied to the cords or the cord spools or rolls, and

suitable devices may be also supplied for described.

At a suitable point or points beyond pulleys 46, the'cords 4 are forced through the shell'material by suitable devices, exemplified in the present instance by a reciprocat ing plunger and stationary support 51, provided with cooperating male and female punch members 52 and 53, by which the shell material is perforated and the cords pushed through and .formed into loops at the proper points, as previously explained. At a' point beyond the punching mechanism 50- and 51, the cover strip C is supplied from roll 55 and is glued, or if it has been previously glued, the adhesive is moistened, by any suitable gluing or moistening device 56. The cover strip then passes over a roll and its adhesive su'r face is pressed against the under side of the shell strip by a roll 61 cooperating with roll 60. In this application of the covering strip, the cord loops are secured in the manner previously described. At a suitable point, such as point 65, beyond the initial application of the cover strip, its margins are turned over upon upper side margins of the cover strip by any suitable mechanism, particular mechanism for this purpose not being shown in the drawing. The

cover margin may befurther pressed and secured in position by cooperating rolls 67 and 68. The continuous blank assembly then advances to a point where individual blanks are severed by cooperatingcut'ting devices 70 and 71.

The individual blanks may be folded and secured in box form by suitable mechanisms which have been devised for the'purpose.

I. have so far described only one exemplification of the method for producing corded boxes, this method being what designate as a continuous method, and also involving at the same time production of covered boxes, these continuous and covered box production methods conforming generally to previous methods of my invention, adapted however, as explained above, to the application of tying cords orjtapes. In its broader aspect the present invention is not limited to the continuous method or tothe covered box production method. Up to the point Where the individual blanks'are severed from a continuous strip assembly, the process steps described are, broadly con sidered, an exemplification of suitable steps for the production of the individual corded blanks of Figure 4. It is also evident that if the cover strip is omitted and other suitable means are provided for securing the cords at the attachment points, suitable uncovered, corded box blanks will be produced. Anv example of this is shown in Figures 8 andf9, in which the cords are attached at suitable pointsb staples 80, appliedfby vany suitable stap ing devices represented in rudimentary form by cooperating staple holding or applying members 81 and dies 82. The staples are applied so that they straddle the cords 4 and the points are punched through the shell material and clinched on the under side by the dies 82. Evidently, uncovered box sections may be produced from the blanks of Figure'9 by folding the parts, as shown in Figure 5, and securing the outer surfaces of the corner laps to inner surfaces of the end wings, by adhesive suitably supplied.

Certain variationsin the order of steps have been previously suggested, and other variations in this respect may be made. No attempt is made to explain all the possible variations of the method, but suitable variations are included in the scope of the appended claims. 1

The form or structure of the box blank and correspondingly the structure of the completed box part may vary greatly, in the broader aspect of the invention, and the production method may be varied in accordance with variations in the desired blank form. For instance, the present invention is adaptable to covered or-uncovered boxes .in which the end wing and corner lap arrang ement or form may vary greatly. Certain end formations of the blank make the cutting of apertures 3. in the continuous shell blank unnecessary, and other end formations of the individual blanks require other to a successionof box-blanks, severing the cord at blank intervals, and shaping the blanks into box form.
