Renewed September 24, 1926.
. My invention relates to methods of producing box blanks and boxes, conveniently described as continuous production methods, in
general conformity with previous box structures and methods of my invention, and also in general conformity with companion applications, executed on even date herewith.
The present application relates more particularly to the box end formation, and es pecially to the provision of a smooth and attractive box end finish in which every portion of the box shell or body material, including all edges, is covered and concealed by portions of the overlying cover paper with the exception that in one variation of the method and o I structure which is preferred in some cases,
thin s'ide edges of the shell end'wings are slightly, (more or less) exposed by reason of the fact that the adjacent edges of the cover paper are cut ofi flush with these shell edges in the formation of the blanks.
Incidental to the provision of a completely or approximately completely finished, smooth and attractive end structure, referred to above the invention includes process steps for reducing the thickness of marginal por trons of the shell end wings, these operations being conveniently described as skiving operations, properly co-ordinated with other operations of my continuous PIOLlLICUOIl method.
Various forms of boxes are here shown and f describedin order that the processes of production may be fully understood; but the blanks and boxes perse are disclosed and claimed in a divisional application.
The characteristics and advantages of the invention are further sufiiciently described in connection with a detail description of the ac- -compa'nying drawings, which explain certain representative performances of the process or method. After considering these examples,
a persons skilled in the at will understand that many variations may be made within the plate the employment ofany methods and scope of the appended claims.

In the process as exemplified in Fig.1 a continuous strip or web of suitable box body or shell material 1 is advanced from a roll 2 plane of one corner of the completed and at a suitable point longitudinal fold linesv 3 are produced in any suitable way. Parperspective view of the comis reduced in thickness by any suitable means on substantially rectangular areas extending inward from the longitudinal fold lines.
This operation is conveniently described as ,Fig. 3.

This operation, however performed, is for the purpose of reducing the thickness of the shell material along certain edges which are sub sequently produced by cutting l'oi punching operations, and most desirably thecutting or removal of material is on an angular or beveled plane in the transverse direction of the blank, so as to gradually reduce the thickness of the material in outward directions. The formation of the shell web including the longitu'dinal fold channels 3 andthe skived or beveled areas 8, is most clearly shown in Inord'er toprovide for free or projecting cover end wing margins in one particular forin of boX, central rectangular openings 10 are cut or punched in the shell material, these openings usually extending all the way from one longitudinal fold line to the other, and concurrently, or otherwise before or after the openings 10 are punched, longitudinal slots 11 are produced in the blank, these being usiially commensurate with the width of the fold lines and of a suitable length extending in both directions from the central openings 10 to correspond to the desired end wing length of the completed box-blank. By this operation thin longitudinal freeedg'es 12 are produced in the shell material at the inner sides of the slots 11.
In the further advance'of the shell material transverse fold lines 14 are produced,
and, desirably these are relatively deep gathered folds in the production of which the shell material is more or less broken down so that it will fold properly with the applied cover material without unduly straining or breaking, the cover material when the individual blanks are folded. In some cases these transverse fold lines may be, formed after the cover materialis applied, and in general iti's to be understood that the order of operations may be varied considerably, andthere is no limitation as to the order of operations except in cases where the particu-- lar operation must necessarily or'most adthe sake of clearness.
performed after the pert A continuous strip or web of suitable cover paper 15 isadvance'd from a roll 16, and desirably during its advance toward the point of contact with theshell webthis pap'erissuitably treated to provide upon its desired indicia or designs, and in the present specific example this treatment of the cover paper consists in embossing it. the cover web is passed between co-operating embossing rolls l7 and 18, carrying suitable embossing dies or surface conformations 19 to produce a suitable embossed design 20 upon the cover paper, and this may be in a particular eziainple a panel of suitable For this purpose indic'ia'oi decorative subject matter, to be located on a stated area of the completed be part, such as the top or bottom area of the box part, or oneof the end or side panels,
or otherwise the embossed design may e3 tend more or less 'over the'entire surface of the cover paper, one suitable all-over embossed design being sufiiciently exemplified in Figures 17 and 18. a
The coverweb isthen passed over a glue roll 21 and is then brought in contact with the shell web and pressed thereon, an upper pressing roll 22 being shown for this purpose in Fig. 2, this roll of course co-operating with a lower pressing roll, which is omitted for a Desirably the cover web is of such width that it has margins 24 projecting beyond the edges of the shell web, and these margins are folded over and pressed on under marginal surfaces of the shell web by pressing rolls 26 and 27. Glued cover paper then overlies the apertures 10 "and llpreviously produced in the same web.
In the further advance of the assembled material slits 28 are formed in the cover paper approximately centrally of the shell slots 11, and these slits are of substantially the same length as the' slotsQ The slitting operations may be performed by rotary slitting wheels 30 as best explained in Fig.
These slitting operations are forthe purpose of severing thecover paper to divide the cover corner laps from the cover end wings.
In the further advance of the continuous assembly, portions are cut from itat regular intervals along the straight transverse lines 35, Fig. 1,produc1ng lndivldual'blank assemwings, and shell end wings (Z having skive'd' or beveled marginal portions 8 with the thin edges 12 produced: in the'manner previously blies B, Fig. 5, each consisting of combined shell and cover material and ncluding a cen end wing end margins 6 extending beyond the endsof the shell end wings and narrow cover I margins f projecting alongsidethe thin shell "edges 12, these covermargins e and f being supplied with adhesive which remains fresh or tacky during the rapidly performed process operations, and the blankalsousually includes narrow cover marginal portions 9 at the opposite sides of the slits 28 to the marginal portions 7, these margins 9 extending alongside the inward edges h of the shell corner laps. The cover margins g are usually immaterial or superfluous but they are usually produced as an incident to the production'ofthe desired margins The width of the margins 9 may be reduced to practically any desired extent or they may be substantially eliminated by making the slits 28 ascloseas is convenient or desirable to the shell edges h. The margins g, however, when produced in the manner 'described, are unob- .jectionable and in the completed box they lie along central portionsofthe transverse fold lines or creases 14 and are more or less, or entirely concealed from view. 1
f The blank is now folded into box form b any suitable number ofintermediate opera- .tions or steps as suficiently indicated in Fig. 13 in which the same style of box is produced with the exception of a slight difference in the end wing side edge formation. In the folding process the sidewin gs b are turned up, the
cornerlaps c are turned in, the end wings cl 1 the corner laps, and finally the pro ecting are turned up against the outer surfaces of oover mar ins e, coated with adhesive as above described, are turnedin and pressed against inward margins of the corner laps and the adhesively coated narrow cover margins f are presseddown and adhesively secured to outer surfaces of the corner laps along thev vertical corners of the box, Fig. 6,
. I "completely, covering and concealing the'thin skivedshell edges 12.v Thesloping or graduated skiving or beveling' of'the shell margins adjacent to the edges 12 moreover provides H for a. substantially; smooth and unbroken outer box end surface. The adhesive application of the cover margins in the described manner is sufiicient inmany cases toretain the box end structure in permanent form, but
when necessary or desirable additional ad "hesive may be supplied to the outer surfaces of the corner laps c or to, the inner surfaces of the shell end wings d, and this adhesive application may be made at any convenient pointin. the process operations either before the materials are severed from the continuous Web or after severing. i,
In the precedmg example of the process a great many of the operations, and all of the 3 operations performed upon the shell material, were performed previous to assembly contact, and especially the narrow strips of cuttingoperat-ions to remove the longitudinal strips are performed afterassembly contact, and therefore, are necessarily performed upon the combined materials, and these figures also illustrate other variations consisting in the formation of transverse fold lines or creases after assembly contact so that the crimping or pressing operations which form the creases are formed on the cover material along with the shell material.
In this performance of the process the shell web 1 is advanced and the longitudinal fold lines in the form of channels 3 are produced by routers l, and at a suitable point skiving wheels 5 produce beveled or skived surfaces 40, Figures 8 and 10, the beveled surfaces 40 merging. in a transverse direction of the blank into the surfaces 41 which constitute the bottomsof the folding channels. In the further advance of the web, central portions are cut or punched out to form openings 10, as in the previous example, but longitudinal slotting of the material along the fold lines is omitted. The cover web 15 is then applied spectively, exposed along the inner edges of the slots. The blank is then severed by transverse cutting as previously shown producing individual blank assemblies B, Fig.
12, which maybe substantially identical with the previous blank assembly except for the formations adjacent to the slots 50. The
blank is folded'into box form by any suitable number of intermediate operations or stages, as sufliciently explained in Fig. 13, with or without the supply of additional adhesive as explained in connection with the previous example, producing the completed box as shown in Figures 14, 15 and 16, having all the characteristics of the previously described structure including completely coveredexterior surfaces and shell edges, and with margms ofthe cover paper applied all around the lnner margins of the side and end walls, except, as a significant difference from the previous structure, the thin edges 5170f the shell end wings are slightly, (more or less) exposed. The skiving operation may be performed so as to make the material along these edges'as thin as may be practicable or' desirable; in other words, the exposed edge portions; including cover material and shell 51 may be so thin that it is practically unnoticeable and indistinguishable from the 7 adjacent superposed edge of the cover material, or otherwise whe'n'it is not practicable to skive the material so deeply, this edge may be somewhat thicker and more noticeable'and this exposure of the edge of the cover material of moderate thickness is unobjectionable in many classes of boxes.
In this particular form of the invention it is usually desirable to supply adhesive at least along the skived surfaces ofthe shell, or on surfaces of the corner laps which will correspond to these skived surfaces when applied. The roughened, skived surfaces of the shell material readily adhere to the corner laps and these surfaces, and especially their edges, are easilypressed down and held in secure engagement so that the edge finish of the box is very secure and durable.
The embossing operation previously described may be carried out in connection with the process as shown in Figures 8 to 16, or the embossing may be omitted, in accordance with requirements.
Figures 17 and 18 illustrate one form of all-ove'r embossing, wherein a mottled or pebbled appearance is imparted to the cover paper 15 by suitable embossing rollers as in Figure 1. When such an all-over? einbossecl design is produced upon the cover material, it is important in the subsequent creasing or folding operations, to avoid injuring the embossed finish, and for thatreason the transverse creases 14 are desirably formed in the shell material before'assembly contact,
in Figure 1, Without any necessity for creasing the combined materials including the cover paper, which would injure or alter the appearance of the embossed paper along the'creased lines.
