To all whom it may concern:

Be it known that we, JACOB P. WRIGHT and CARL A. CARLSON, both citizens of the United States, and both residents of Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Processes of Making Reinforced Paper Boxes, of which the following is a specification.

he ob ect of this invention is to provide a simple, eficient' and economical process of making rectangular paper .or paste-board boxes having their walls reinforced and strengthened by inturned integral folds or extensions of the material of which the bodies of the boxes are composed.

In carrying out the invention in the preferred way we provide a strip of box material equal in width, plus reinforcing side flaps or folds, to ordinary box stock, whichstr1p is drawn from a suitable roll and subjected to the progresslve operations illus-- trated in the annexed .drawlngs, where1n Figure 1 is a plan of a portlon of a strip of box-stock which has been subjected to glue-applying, scoring, punching and sidefolding operations preparatory to the severance of a box-blank from the body of the strip. 30

Fig. 2 is a plan of the severed blank. 7

Figs. 3, 4, 5 and 6 illustrate successive conditions of the blank during the box-forming operation.

Fig. 7 represents the finished box.

The strip of box material A is drawn from a suitable roll in the direction indicated by the arrow. As the strip progresses it is supplied at predetermined intervals with surface lines or spots of glue, as at a, It'is then longitudinally scored on parallel lines I), c which respectively define the fold lines of the side walls of the box and of the reinforcing folds thereof. Longitudinal parallel shts, as d, are formed in the body of the strip, at regular spaced. intervals in the length of the strip, and substantially rectangular recesses, as at e, having their basal edges in spaced arallel relationto tne slits are formed in t e longitudinal edges of the strip; the inner corners of the recesses being notched or incut parallel to the slits. Such slits, recesses and notchesdefine the reinforcing laps 7, corner tongues g, and end folds k for succeeding boxes. The

side laps, f, thus produced are folded inwardly upon and glued to the main side portions of the strip asindicated at i. The strip 1s then transversely scored on the lines j and It to provide fold lines for the end andcorner portions of the box. The strip is then transversely severed midway between the ends ofthe succeeding side folds as on the line Z, thus producing a box blank having two-ply side portions, end extensions 72.

from the side folds, and end extensions m from the bottom, as shown in Fig. 2.

The two-ply side ortions of the strip are then, bent upward a ong the basal fold line has indicated in Fig. 3, and each pair of end extensions 11. are then turned inwardly on the fold lines is, at. right angles to the upstanding sides, so as to overlap, as shown in Fig. 4. The tongues 9 being flexed by the inward folding of the end extensions reinforce the corners of the box. The bottom extensions m are then turned upward on the fold hnes k as indicated in Fig. 5. The upper portions, rising above the .inturned extensions h, are then turned inwardly on the fold lines 7', as seen in Fig. 6, and folded down against the inner sides of the end' extensions h and the corner tongues, as seen in Fig. 7. At the same time the inturned side and end folds are pressed hard against the adjacent surfaces of the structure so as to insure the effective union of the contiguous parts. We claim 1'. A process of making reinforced boxes which comprises forming in the body of a stri of box material, at spaced intervals in the length of the strip,pairs of longitudinal parallel slits; formin in the respective lonmedially of the slitted and recessed portions Y of the strip, thereby forming successive box blanks.

2. A process of. making reinforced boxes which comprises forming in the body of a strip of box material, at spaced intervals in the length of the strip, pairs of longitudinal parallel slits; forming in the respective longitudianl edges of the said strip recesses having their basal edges in spaced parallel relation to the slits and having their inner corners incut parallel to the slits, thereby providing pairs of side laps alternating with the pairs of slits and having end tongues; folding said laps and their tongues upon and securing them to the adjacent portions of the strip; and severing the strip on transverse lines medially of the slitted and recessed portions of the strip, thereby forming successive box blanks.

3. A process of making reinforced boxes Which comprises forming in the body of a strip of box material, at spaced intervals in the length of the strip, pairs of longitudinal parallel slits; forming in the respective longitudinal edges of the said strip recesses having their basal edges in spaced parallel relation to the slits; thereby providing pairs of side laps alternating with the pairs of slits; folding said laps upon and securing them to the adjacent portions of the strip; severing the strip on transverse line medially or" the slitted and recessed portions the strip to form successive box blanks; and, .finally, bending and uniting the lateral and neaaeee end portions of the blanks to provide boxes having reinforced sides and ends.

i. A process of making reinforced boxes Which comprises forming in the body of a strip of box material, at spaced intervals in the length of the strip, pairs of longitudinal parallel slit-s; forming in the respective longitudinal edges of the said strip recesses having their basal edges in spaced parallel relation to the slits and having their inner corners incut parallel to the slits, thereby providing spaced pairs of side laps alternating with the pairs of slits and having end tongues; folding said laps and their tongues upon and securing them to the adjacent portions of the strip; severing the strip on transverse lines medially of the slitted and recessed portions of the strip to form successive box blanks; and, finally, bending and uniting the lateral and end portions of the blanks to provide boxes having reinforced sides, ends and corners.
