A glue applying mechanism is attached to the Fig. 10 is a side elevation of said latter mech die I8 and comprises a receptacle or reservoir 23 anism. (Figs. 9 and 11) having a plate 24 partly cover Fig. 11 is a cross section on line II—II of ing the open top of the same. A roller 25, (Fig. Fig. 9. 11), is revolubly mounted in the receptacle 23, 55 2 2,105,726 and a series of grooves 26 is formed in the peripheral surface of the roller. Glue or other adhesive is inserted in the receptacle at the open ing 2'! and the roller 25 is turned in the adhesive, the material being carried up in the grooves 26. A scraper blade 28 is adapted to bear on the roller 25 and is mounted on a shaft 29 that extends across the reservoir, and a lever 30 is attached to the shaft by which the shaft may be turned to adjust the blade relatively to the roller. Gen erally the blade is adjusted to‘ scrape the adhesive from the surface of the ribs 3! on the roller,.»the adhesive in the grooves being applied to the mate peripheries of the Wheels 66 and are adapted to engage in the aperture 63 formed in the belts 64 that are engaged on the wheels 60, 6|. Openings 65 are formed at selected intervals in each belt and a spring stop 66 is secured on the underside 5 of the belt adjacent to each opening so that the stop projects through the opening. A frame 68 projects forwardly from the front side of the main frame and supports a series of rods 69 and cross rods 19. The rear ends of the rods‘ 16 are slid- 10 ably mounted on a rod ‘l'i supported on the main frame and the forward ends thereof are slidably "mountedon the rod '12 so that lateral adjustment :of the 'rods‘may'be accomplished to accommodate as will hold the desired amount of adhesive to be various sizes of material. The rods 69 are also 15 adjustable on the rods 16. The Wheels 66, 6| The roller 32 is supported by the frame 33 that ‘may also be adjusted on their respective shafts is pivotally mounted on the‘projecticns ‘34 bf the in accordance with the size of the material. A ratchet wheel 73 is mounted on the shaft 14 opposite side walls of the receptacle by‘the studs rial being treated. The gr'oc'u'fesv are‘ or such" depth applied. _ I i 35. Two plungers 36, opposed by the‘springs 31, which supports the wheels 60 and an arm 15 20 are mounted in the frame 33 and are adopted to abut the plate 24. A cam shaft 36 engages the is pivotally connected to the shaft and carries upper side'of the frame 33 and'is supported in the brackets 39 that are mounted on the studs , 35 and attached by thescrews 46 to the receptacle. a pawl 16. A rod ‘H’ is pivoted to- the arm 15 and to a crank 18 connected to the shaft 1. The rotation of the shaft l causes the rod TI to rock the arm '55, the downward movement of the arm 325 A crank 4! is connected to the shaft 36, the down causing the pawl '76 to turn the ratchet ‘l3 and ward‘movement of which causes the frame 33 to -_ tilt 0n the pivots 35 and‘raise the upper roller the shaft the distance of one tooth. The ratchet for stopping the feeding of the ribbon or tape 42. The plungers 36 normally hold the roller 32 in contact with the roller 25. Two channels 43 are mounted on‘ opposite sides of the receptacle and project rearwardly there from. These channels serve as guides for the rib bon or tape 42 formed of suitable material such as paper board of selected weight. The tape is in a roll 44 revolubly mounted at one end of the main frame and it passes between the rollers 25, 32 and through a slot 45 in the forward end wall of the receptacle 23 and through a V-shaped slot 46 in the die iii. The free end of the tape extends across the slot 22 in the die I 6 and under the knife l3 is'preferably adjustably detachably mounted on a gear '19 that is ?xed on the shaft 14. A pinion '89 mounted on the ratchet engages‘ thei‘i‘l'ill teeth of the gear and the ratchet when released from the gear may be adjusted by rotation on the gear. The intermittent rotation of the shaft 14 causes the wheels 69 to drive the belts 64 inter mittently. A brake 8! on the shaft "14 prevents3‘35 overrunning of the same at any rotation. A form of brake is illustrated in Fig.3 in which a shoe 52 is mounted to engage the rim of the wheel 66. A cam 83 is adapted to force the shoe against the rim. A crank 84 is adapted to rotate the camgtm and an adustablerod B5 is connected to the crank and to a crank 86 secured to the shaft 81. A 2|. A suitable-number of spring opposed pawls crank 88 is also secured to the shaft 81 and a 41 is mounted in recesses formed in the die H3. ' rod 89 is connected to the crank 88 and loosely engages a lever 96 that is pivoted at 9| and ens-.545 The pawls project into the slot‘ 22 beneath the tape and, when the descending knife severs a strip from the tape, hold the strip in horizontal posi the brake is caused to intermittently operate. tion as the knife carries’ the strip through and out of the slot 22 and presses it ‘onto the object The springs 93 are attached to the rod 89 and to the lever so that the rod is resiliently connected below the die “3, that is being treated. , to the lever. A hand wheel 48 is attached to the shaft of the roller 32 by which to rotate the rollers for initially drawing the tape 42 between the rollers. A gear 49 is attached to the opposite end of the shaft of the roller 32 and meshes with a gear 56 attached to the shaft of the roller 25. A ratchet wheel 5! is also attached to the shaft of the roller 32 and is adapted to be intermittently'ro tated by a dog 52 (Fig. 14) mounted on the head 2. A stop 53 engages the ratchet wheel to pre vent overrunning and to lock the wheel against reverse movement. The dog 52 causes the wheel 5| to rotate on the upward movement of the A brake 93 (Fig. 15) is also applied to the shaft 74 adjacent to the rachet wheel '13. Other‘similar brakes 94, 95 are applied to the shaft 3, and the reservoir. . A guard 45' protects the slot 45 from the ad gages under a cam 92 on the shaft 1 by which cam _ a:to ‘shaft '96 of the other head‘ 2','which head is a duplicate of the head 2 with’like parts, but it ‘isn't-,5 turned around 180 degrees so that the die and knife face the die and knife on the head 2. The head 2' is adjustably mounted on the main frame for. movement toward or from the head 2, where by to accommodate the machine to various sizesn?o of box blanks. A similar glue applying mecha nism 23' and roll of paper board'tape are applied to the head 2'. I The box blanks which are‘similar to the blank A shown in Fig. 16 without thev strips B, are feds-.65 consecutively onto the carrier belts between the ‘rods 69 and 16, the guides 98 on the rods 69 and the receptacle 23 having the slots 56 in the lateral ' the guides 99 on the rods 76 locating the proper projections 51 thereon to receive the bolts. vWhen position for the deposit of the blanks.

The bolts 54, (Fig. 9), are pivo - ally connected to the die»! 8 in the slots .55 therein, the nuts on the bolts are tightened against the projections 51 the receptacle is rigidly attached to the die‘ I8 and hence reciprocates withit. Two pairs of wheels 6|], 6| are revolubly mounted on‘ opposite ‘sides of the main frame respectively. Pins ‘62 project at selected intervals 1from‘~'the on ‘the belts which are in front of the blank en-" 70 gage the edge of the blank and carry'it in stages to a positionunder the dies IS, the guides" I00 causing the blank to center correctly on the base plate or topl?l of the main frame. The several cams and operating parts are‘cor-i-i75 2,105,726 rectly timed in operation so that when a blank is carried under the dies 18, those dies with the attached reservoirs descend and their tension plates 20 contact with the blank. The knives then descend, cut off the glued strips B and press them glue side down onto the blank. The dies and knives rise and the belts remove the blank just treated and position the next blank under the dies and knives. As the die-reservoir units rise the ratchet wheels 5! on the upper rollers of the reservoirs contact the dogs 52 and turn one tooth thereby rotating the rollers and feeding the glued tapes into the slots 22 in the dies. The next de scent of the knives cuts off the strips B which 15 drop onto the pawls in horizontal position so that the knives push them through the slots in hori Zontal position into engagement with the box blank. The stripped blanks may be conveyed from the machine in any convenient manner. 20 It is thus seen that the box blanks are fed suc cessively under the knives and the tapes are fed at right angles to the path of movement of the box blanks, an adhesive being applied to the un der side of the tapes as they approach the knives 25 so that the descending knives cut off strips of the tape and apply two of them to each blank simultaneously. In Fig. 17, I illustrate a sectional view of a fraction of a box blank in set up condition show ing the end wall folded over ‘the collapsed cor ners and a flap on said wall engaged behind the strip B. 3 means to drive the belt intermittently for carry ing the material into and from registration with the die and a knife cooperating with the die and independently reciprocable for cutting a strip from the tape and applying it to the said material. 2. In a strip cutting and applying machine a reciprocating die, a reciprocable knife, a flexi ble belt to feed material to be treated under the die, means to feed a tape to the die and under the knife comprising a container for an adhesive 10 substance, a pair of rollers supported by the con tainer and adapted to receive and intermittently move the tape between them, one of the rollers being rotatable in the adhesive mixture and hav ing a series of annular grooves in its periphery 15 in which'the adhesive is retained and applied to one side of the moving tape, means to cause rota tion of one of the rollers, the knife being adapted to out a strip from the tape and apply it to the said material, means opposing separation of the 20 rollers and means to separate the rollers. 3. In a strip cutting and applying machine, a main frame, a head mounted on the frame, a reciprocable plunger on the head, a knife car ried by the plunger, a reciprocable die mounted 25 on the main frame and adapted to receive the knife, means to reciprocate the die in advance of the reciprocation of the plunger, an apertured ?exible belt adapted to intermittently travel un der the die for carrying material to be treated to 30 and from the die, a pair of rotatable members supporting the belt, at least one of said members having pins projecting from its periphery and What I claim is: 1. In a strip cutting and applying machine, a reciprocating die, means to feed a tape to the die and simultaneously apply an adhesive substance to one side of the tape, a ?exible belt having de adapted to engage in certain of the apertures in the belt for driving the belt and spring stops 35 mounted at other of said apertures in the belt for engaging an edge of the said material to cause pressible upstanding stops at selected intervals of its length for engaging material to be treated, the material to travel with the belt.
