MOUNTING CUTTERS ON BOX BLANKS Filed Dec. 4, 1930 2 {NVENTOLMW d www #ATTORNEYS Patented Feb. 2, 1932 l UNITED STATES lPATENT oFFllcE NICHOLAS MARCALUS, 0F ELIZABETH, NEW JERSEY, ASSIGNOR TO AUTOMATIC PAPER` MACHINERY CO. INC., A CORPORATION OF NEW JERSEY MOUNTING CUTTERS ON BOX BLANKS Application filed December 4, 1330. Serial No. 499,959.

This invention relates to the manufacture of boxesfor the dispensing of rolled paper and \as to do particularly with a method and machine for mounting a cutting strip of a hard non-metallic substance on an edge a box blank.

In my Patent No. 1,630,495 I have described .and claimed a dispensing box for rolled paper provided with al serrated metal cutter secured tothe upper edge of the front wall of the box, across which cutter the paper is torn after the desired length has been unwound. This box has been successfully used commercially as a dispensing container for rolled waxed paper. When the Vpaper is used up the box is thrown away. It is not refilled.

The entire package including the box with its cutter and the roll of paper must be sold for a few cents whichmeans that the box itself with the cutter must cost vnot more than half a cent-preferably less.. One of the important items contributing to the cost of the box is the metal out of which the cutter is fashioned. 'Cheaper materials, indurated paper such as stencil board, stili.' parchmentized paper and the like, have been proposed, but their. use has necessitated rela-- tivelyexpensive preforming and stapling operations.

' In accordance with the present inventlon i I have provided a method and a machine by means of which a sheet of indurated paper' and a box blank. are fed to a pressl in over-- lapping relationship, and a cutting element severed from the forward end of the sheet and secured along the edge of the box blank and in so doing serrates its cutting edge. In

order that the shearing operation which severs the cutting element from the sheet of cutter material shall not disturb the relation between that element and the box blank, I so arrange the press that pressure is applied to the overlapping edges of the blank thereafter.

l In the accompanying drawings I vhave lllustrated a machine embodying my invention and also a completed box manufactured 1n: accordance with it. In these drawings,

Flgure 1 is a front elevation, partly in sect1on, of a press embodying the; invention;

Figure 2 is a horizontal section taken along 6 l1ne 2 2 of Figure 1 and Figure 3 is a group of details of the completed box'.

In these drawings, 1 indicates a punch press of ordinary construction, except as redesigned 1n accordance with my invention. 65

Mounted on the vertically reciprocable ram 30 of the press is a spring-pressed pressure member 2 and a shearing die 3 provided with a serrated cutting edge. An anvil 15 is bolted on the bed of the press and co-op-erates with 7 theeparts carried by the ram. Mounted wlthin this anvil are two spring-pressed lplungers 16 designed to co-operate with the .are mounted stops 18 which serve to position the blank Bfwhile the spring-pressed plungers 16 serve as positioning stops for the cutter material C.

Mounted on a bracket on the lower righthand side of the press, as viewed in Figure 1, is a `jumbo roll 14 of indurated paper orstencil board which forms the cutter ma.-` terial. This paper is fed upward and hori- D0 zontally forward against the plungers 16 by passing between feed rollers 9 and 13.A The roller 13 is preferably a cylindrical roller extending the full width of the cutter material, but, as illustrated in Figure 2, there D5 lare two roller'sections 9. Mounted on the same'shaft as the roller sections 9 are three glue-applying rollers or disks 8 provided with 'a plurality of peripherally spaced glueapplying areas. Mounted adjacent the roll- 1c:

ers 8 and 9, and contacting with the former,

Lare three glue-feeding rollers or disks 10 by means of a link 5 to an oscillating armv 31 loosely mounted on the shaft carrying the rollers 8 and 9. This arm 31 is provided with a pawl 6 co-operating with a ratchet 7 lixed to the shaft. During each downward movement of the ram the pawl 6 slides over the ratchet teeth, but on each upward movement it engages one of the teeth and rotates the feeding rollers 9, and with them the feeding roller 13 and the glue disks 10. This rotation feeds the cutter material forward and applies spots of glue to its upper face.

The operation of the machine is as follows: With the cutter material C in the position illustrated in Figure 1 with its forward edge abutting against the spring-pressed plunger 16, the operator places the box blank B against the stops 18 so that its forward edge overlaps the forward end of the cutter material, the parts then occupying the position shown in Figure 1. Upon the next downward movement of the ram, the presser 2 forces the forward edge of the box blank into contact with the glued forward end of the cutter material and exerts sufficient pressure to join the two. The same blow of the press shears 'a cutting element from the'forward end of the sheet of cutter material between the upper movable die 3 and the lower fixed die 17. The pressing and cutting actions are effected almost simultaneously,l but as the presser 2 extends normally slightly below the movable die' 3, as illustrated in Figure 1, pressure on the overlapping blank and cutter material is effected slightly before the shearing action takes place, so that .the parts` arel firmly held together during the shearing action. On the return movement of the ram,-:V

due to the action of the presser spring, the shearing dies separate slightly before the presser releases its pressure on the blank and cutter, thus insuring that the stripping of the dies shall not, in any way, disturb the relation between the severed cutter and the blank. During the upward movement ofthe ram the operator removes the blank upon which the cutter has been mounted and substitutes a new blank. Meanwhile, through the operation of the pawl and ratchet 6 and 7, the cutter sheet has been fed forward again against the plungers 16 and the parts are in readiness fora second operation. The glue disks 8 applythe requisite amount of glue in three spots as the cutter material is fed forward, these glue spots being so positioned as to fall beneath the overlapping end of the box blank during the pressing operation, but so as not to extend beyond the edge of the blank and appear on the serrated' edge.

After each pressing and severing operation the blank is provided with a serrated cutting edge as illustrated clearly in Figure 2, the serrations extending slightly beyond the for- .v ward edge of the blank.

Figure 3 illustrates a blank with its cutting edge after it has beenl folded into box form, and also illustrates the manner in which the rolled paper Within the box is unwound and torn olf along the serrated cutting edge.

By means of the method and machine of my invention I am enabled to use a cutter material cheaper than metal. By mounting the cutter on the boxblank and severing itl at one blow of the press, and by feeding the.

cutter material automatically I can further reduce the cost of operation.

I claim:
