Application filed September 2 This invention refers broadly to improvements in means, for the manufacture of paper-boxes, card-board-boxes and the like containers, and it-is particularly intended to devise means of applying the reinforcing or corners of such strengthening strips to the and to generally boxes, cartons and the like,

' improve and facilitate the process of manu- 'cedure, however,

facture and to produce a product of, greater durability and applicability than generally obtainable heretofore. In the well known methods ofmanufacture of such boxes and the like, as practicedheretofore it has been the usual practice to paste the adhesive reinforcing strips from the outside upon the connecting edges of the boxes, which proentails difficulties and inconveniences -in many cases, as for instance -in the case offancy and artistic boxes. For

various purposes it is for instance the commonpractice to provide the paperand'cardboard boxes with printed and similar matter or with embossed and decorative or'ornamental portions, in which case the subsequent pasting of the edges by means of applying like tothe corners or outer edges destroys the appearance of the box,

unlessthenature of the connecting strips is very carefully adapted to the character of the printing or ornamentation. This problem, however, presents various difficulties,

and it is obvious that the pasting will not invention to I viously printed boxes to be performed by stick, if for instance a painted box is used.

These difliculties may, be avoided 11000111- iIig to my invention and various otheradvantages are accomplished by applying the pasting strips solely at. the inside of the boxes,

so that they will not be readily detected in the finished boxes. Even in those cases in which the box in the unfinished condition is provided at its corners with exterior pasting it is of advantage to first apply the strips, connecting strips at the inside, so as to obtain a perfectly smooth'exterior surface for the even and secure applicationof the exterior strips. Itis also possible according to this have the inside pasting of prethe consumer himself, so that the cut-out pat- -are. forced upwards by BOXES, canmaonnn noxnsfann run LIKE- 1926, Serial No.138,-112 and in Germany beeember 3, 1925.

terns for the boxes in the flat condition may be delivered to the consumers or customers,-

also be applied as heretofore vtothe outside of the boxes according to this in vention, and in accordance with a modified construction of the invention it becomes possible to apply the pasting strips simultaneously both to the outside and to the inside of the boxes.

In the accompanying drawings illustrating the invention, i Figs. 1 is a side elevation of a box making machine embodying the invention;

- Figs. 1*,1 and 1 are, respectively, sections on lines 1 -1, 11 and 1f-- of Fig. 1. Fig. 2 is a front elevation of the same. Figs. 3', 5 and 7 are vertical sections through the anvil and die and related portions of the machine, showing the samein dif- "5 and 7.

Fig. -9 is a vertical section through the anvil, die and knives.

Fig. 10 is a view of a finished box.

Figs. 11, 12 and13 are detail views of the cutting knives. y

In the construction disclosed the anvil 1 is composed of a relatively narrow, rigid cenv ter portion 31 and movable lateral portions 32 which by means of pins 33 are guided in inclined slots34 of the center part 31 and the springs 35. The upper surfaces of the parts 31, 32 have a roof-like inclination in such a manner that, when the sections 32 are lowered, their upper surfaces will complement the surface of the section 31 so as to form a continuous angular portions of the parts 32 are provided with anvil surface. Theupper inclined marginal 1 recesses or interruptions 36 forming narrow teeth.

On the part 31 there are rotatably'journaled interengaging lever like toothed segments 37 on pins 37 in cut-outs 32' of parts 32 and extending with their; pins 38 into these parts. (Fig. 1). Upon the parts 32- being moved downwardly by the stamp 40, 41, there will always ensue an even displacement parallel tothe oblique slots 34'as' .on pressureupon either part 32 by oscillatlon of the segments both parts will be positively taken-along. The part 31 is telescopically 40, 41the latter section 41 is guided horizontally, so as to be easily movable along the section 40 and upon the inner terminal head portion of the section 41 a knife blade42 with V-shaped edge is secured. (Fig. 13). A spring 43 forces the part 41 w th the knife 42-against the counter knife'44 (Fig. 11). This knife 44 possesses two spacedly superimposed V- shaped cutting edges 45, 46 and is secured to a slide member 47 which is vertieally displaceable on a guide body 48' fixed in the machine frame 48 and is forced upwards by means of a spring 49. On the pressing die 40, a roller 50 is disposed which upon the descent of the die 39 strikes against a lever 51 which by means of a lever 52 moves the slide 47 with the knife 44 downwards. As the counter knife for the knife edge 46 of the knife 44 a knife 53 (Fig. 12) is se cured to the guide body 48.

On the machineframe 48 there are provided two staggered transport means 54, 55, in the form of rollers 61, 62 and 63, 64 respectively, for the reinforcing strips 56, 57. The rollers are rotated in any well known manner, not shown here, upon starting the machine, until the strips 56, 57 have been advanced between'the anvil and the stamp the distance of the box height, whereby they pass through'the openings 58, 59 of the knives 44 and 53. The strips 56, 57 are gummed, the strip 56 on its lower face and the strip 57 on its upper face. On the strips running through between the rollers 61-64 they are bent thereby into V-shape, and simultaneously they are moistened by the rollers 62 and 64 which dip into the water tanks 65, 66 in such manner that the adhesive matter on the strips is softened and made sticky. On strip 57. the moisture permeates the paper structure and softens the adhesive.

This apparatus operates substantially as follows: The anvil is so adjusted that the box with its inner edge portion mounted thereon is adapted to impinge against the knife 44, if the bottom of the box rests upon the head Surfaces of the anxil sections 32. The position of the anvil herein shown corresponds to the treatment of the largest sizes of pieces of work. If shallower boxes are tobe operated upon, the anvil must be moved inwardly. Since on such displacement the may also beclisplaced. After the boxes 60' have been mounted in position the driving means are operated causing the pasting strips 56. 57 to be first advanced,'and the strip 56 to be disposed above and the strip 57 below within the box. (Figs. 1 and 2.) Thereupon the pressing die 39, 40, 41 is depressed. This causes the knife 42 to cut off the strip 56 which drops upon the edge of the box (Figs. 3 and 4) and upon the further descent of the pressing die 41 its pressing surface places itself upon the outer strip 56 and upon the box 60 and upon the lateral anvil sections 32, whereupon the-roller 50 strikes the lever 51 which-latter causes the descent of the knife 44 by which means the inner strip 56 is likewise cut off which places itself upon the central anvil portion 31 (Figs. 5 and 6). The continued movement of the pressing die 41 with the box 60 and the pasting strip 56 does not take place any more in the vertical .direction, so as to avoid the interior pasting strip 57 being glued to the box in aposition so as to project beyond the box for the, thickness of the knife 44. In view thereof the parts 41. 56. 60, 36 and 32 are now angularly moved to the rear, in which movement the anvil sections 32 are positively and slidingly guided in the slots 34, while the die section 41 provided with an inclined head surface is subsequently forced down in accordance with the inclined surface 61 of the knife 44 (Figs. 7 and 8). In the lowest position corresponding to Fig. 8 the rear edges of the anvil, of the pressing die, of the box and of the two, pasting strips are exactly in the same plane, so that a neat and entirely unobjectionable piece of work in accordance with Fig. 10 is obtained. v
