MACHINE FOR MAKING PAPER BOX-BLNKS.

Specification of Letters Patent.

Patented May 8, 1911"?.

To all whom t may concern:

Be it known that we, HORACE INMAN and FRANK M. JosLIN, citizens of the United States, residing at Amsterdam, in the county of Montgomery and Statel of New York, have invented certain new and useful improvements in Machines for Making Paper Box-- Blanks, of which the following is a specification.

This invention relates to machines for making paper box blanks and more particularly to machines of this class which form the web from a plurality of layers of paper,

rint the web and die and crease the blanks so that the blanks as delivered from the machine are; ready to be folded to form a completed box.

One of the objects of the invention is to provide a machine of this class which is capable of forming box blanks from a co1nparatively heavy web and in which the web moves continuously from one end of the machine to the other without interruption. In a machine of this character, where the web is formed of thick paper, the rolls as received from` the paper mill are very' large and heavy so as to provide a very long strip, and thereby avoid frequent renewals of the rolls, so that the machine may be operated continuously for considerable periods of time.

A further object of the invention is to provide a machine in which the web is made into box blanks immediately after being formed and while moist so that the outer surfaces or coatings of the web will not be broken in forming the creases in the blank.

Other objects and the features of novelty will be apparent from the following description taken in connection `with the accompanying drawings, in which,

Figure 1 is a side elevation of the machine;

Fig. 2 is a plan.;

Fig. 3 is a longitudinal section of the printing mechanism;

Fig. 4 is an enlarged section on the line 6-6 -of Fig. 1, and

Fig. is a plan of the boX blank as formed by the creasing and dieing mechanism.

Referring to the drawings, A designates generally the web-forming mechanism, B the printing mechanism and C the dieing and scoring mechanism.

and 13, which carry the rolls of paper a and 'b respectively. The bearings 11 may be of ordinary construction but are preferably 60 provided with means for adjustment whereby the rolls of paper may be properly alined.

In the drawings we have shown an additional roll of paper c, carried by a spindle 14, this spindle being mounted in suitable bearings 15, carried by the pedestals 16.

The frame 10 supports a paste-tank 17, bearings 18 for a guide-roller 19, and brackets 20 which carry a guide-roller 21, the latter roller being preferably arranged to be vertically adjustable by mea-ns of the usual rack and pinion actuated by a hand- Wheel 22. rlhe frame 10 also supports the pedestals 23 and 24. The pedestal 23 supports a pair of squeezing rollers 23', these rollers being preferably supported by anyj/Y suitable mechanism permitting the upper roller to be adjusted vertically. The pedestals 24, carry two pairs of pressure rolls 25 and 26, the upper roll of each pair being preferably vertically adjustable. The pedestals 24 also carry a guide-roller 27. The lower roll of the pressure rolls 26 may be driven from the printing mechanism by means of a chain 28 and a sprocket 29, the

vlatter being on one end of the shaft of the lower roll. On the opposite end of this shaft is a gear 30,- which drives the lower roll of the pair of rolls 25 by means of a. gear 31 on the shaft of the lower roll and an intermediate gear 32, which meshes with the gears 30 and 31.

r1`he pairs of rolls 25 and 26 serve as feeding rolls as well as means for pressing the strips together. The paper from the roll b unwinds from the top of the roll and as clearly shown in Fig. 1, passes over a guideroller 33 mounted on the top of the pedestals 23, and under the guide-roller 27. The paper from the roll a is unwound from the bottom of the roll and passes under a guide- Asponding platen.

of thbroughly coated with paste. From the roller 21 the paper passes through the squeezing Vrolls 23 and then between the pairs of pressure rollers 25 and 426. The paper from the roll c is unwound from the bottom thereof and also passes under the guide-roller-34. From the gulde-roller 34 this paper passes over a guide-roller 35 and under a guide-roller 36 and from the latter 4to the pressure-rollers 25 and 26.

It Will thus be seen that the three strips .will be brought together in the pressure rolls with the strip from the roll above the strip from the roll a and the strip from the roll o below the strip from the roll 0;. The strips from the rolls b and c 1n passing though the pressure rolls will be caused to adhere to the strip from the roll a, owlng to the fact that the latter is coated with paste on both sides in passing through the pastetank. When the web emergesl from the pressure rolls 26 it will be in the form of a comparatively stiff board with the three strips firmly secured together.

The printing machine consists essentially of a type roll 37, supportedby means of suitable bearings and arranged above a platen 38. The type on the roll 37 may be inked by any suitable inking mechanism 39. When the blanks are to be printed in one color only a single type roll 37 is necessary, but when two or more colors are to be employed in printing there are provided separate-type rolls and platens for each color. In the drawings we have illustrated a machine adapted to print two colors and have shown two type rolls 37 and platens 38. In order to drive the type rolls each may be provided with a gear 39, which meshes with a gear 40 on the shaft ofthe corre- The gears 40 may be driven by means of a gear 41 which is suitably supported on the frame of the machine and driven by means of a pinion 42 on a shaft 43, this shaft being preferably driven by means of a pulley 44 from any suitable source of power. The printing mechanism may be provided with a pair of feed rollers 45 which may be driven by means of the gears 4 6 from one of the gears 40 by means of an intermediate gear 47. A sprocket 48 may be arranged on the shaft of one of the feed rollers 45, this sprocket driving the chain 28. At the opposite end of the printing mechanism from the feed rollers 45 may be arranged one or more pairs of longitudinal creasing rolls 49, these rolls being preferably driven by means of gears arranged in a manner similar to that of the driving gears for the feeding rolls just described.

The web is fed from the web-forming mechanism to the printing rolls by means of the feed rolls 45 and from the printing rolls passes through the creasing rolls 49, which form the longitudinal creases w in the blanks, and from the creasing rolls into the dieing and cross creasing mechanism.

The dieing and cross creasing mechanism consists of a frame 50 on 'which run the die carriages 51, 52, 53 and 54. The frame'50 carries the four upright guides 55 which are connected together at their tops by means of a suitable frame 56. The cross heads 57 are arranged above the carriages 51, 52, 53 and 54 and provided with suitable sleeves 58 which loosely engage the upright guides 55 whereby the cross heads are adapted to be reciprocated vertically. The frame 50 carries shafts 59 which have arranged at their ends the crank disks 60 having the crank pins 61.' The crank pins 61 are connectedl means of a chain 66. In order to drive the chain 66 a shaft 67 is arranged on the frame `of the printing mechanism and provided with a sprocket 68 which may be driven from a sprocket 69 on the shaft of one of the type rolls 37 by means of a chain 70.

Each of the carriages 51, 52, 53 and 54 carries a bed-plate 71 and these plates are connected together by means of the longitudinally extending bars 72, arranged at the opposite ends of the bed-plates and provided with slots 73 and suitable securing bolts 74 whereby the position of the carriages may be adjusted along the vbars 72. The frame 50 supports a shaft 75 by "means `of bearing brackets 76. and this shaft is driven by means of a sprocket 77 and chain 78 from the shaft 67. At the ends of the shaft 75 are arranged the wheels 79 which carry the crank pins 80. The pins 80 are connected with pins 81 on the bars 72 by means of the connecting rods 82 so that when the shaft 75 is rotated the carriages 51, 52, 53 and 54 will be simultaneously moved back and forth on the frame 50.

The inner sides of the cross heads 57 are provided With suitable roll grooves 83 in which are arranged the rolls 84 at the ends of the die plates 85.

Secured to the opposite ends of the bed plates 71 are the upright guide-posts 86 which pass through and loosely engage suitable openings in the die plates 85, these up rights 86 serving as vertical guides for the die plates. Owing to the arrangement of the rolls 84 in the lgrooves 83 in the cross heads it Will be seen that the die plates 85 are also permitted to move longitudinally Leathery Whlch are mounted on the carriages 51, 52,

.53 and 54.

A pair of feed rolls 87 is arranged at the delivery end of the mechanism and preferably have a peripheral speed shghtly greater than the speed of the web wherebyI these rolls are adapted to quickly discharge the blank from the machine after the same has been severed from the web.

The operation of the dieing mechanism is as follows: The rotation of the shafts 59 causes the cross heads 57 and the die plates 85 to be reciprocated vertically and the rotation of the shaft causesthe carriages 51, 52, 53 and 54 With their bed plates 71 and the die plates 85 to be reciprocated horizontally. rI`he speed of the shaft 7 5 is preferably such that When the cranks are moving substantially in a horizontal plane, which occurs when the cranks are directly above and below the shaft 75, the velocity of the carriages Will be substantially equal to the velocity of the Web. rlfhe mechanism for vertically reciprocating the die plates is so timed that When the carriages are moving in the direction of movement of the Web and at substantially the same velocity as the Web the dies will come into operation and simultaneously cut the notches m and make the cross scores y and sever the blank from the Web by making the cut a. @Wing to the fact that the dies are traveling With the Web at the time they come into engagement With the Web it Will be seen that the blank may be formed Without interrupting the movement of the web. lThis is of especial advantage in a machine vof this kind which makes the blanks from a Web of heavy material and utilizes the large rolls of paper a, b and c. It will be readily understood that it is impracticable to start and stop the rolls every time a blank is formed and therefore by providing the mechanism above described this diiiculty has been overcome by having the dies move With the Web When they form the blank. In box blank making machines the blank has usually been severed from the Web heretofore by means of knives arranged transversely of the Web and carried by a rotating shaft. While this construction Which has been heretofore used has been more or less satisfactory for thin Webs, yet it cannot be used for thick Webs and therefore by providing a cutting die which has a movement at right angles to the Web, We are able to sever the blank from the web by a clean perfectly square cut. The cross-creasing and dieing mechanism above described is the sole invention of Frank M. Joslin and is claimed in application No. 712,127, filed July29, 1912.

From the foregoing description it will be seen that we have provided a machine Which is adapted to. form a continuously moving web which is printed and formed into blanks Without interrupting the movement thereof.

It will be obvious that the printing mechanism may be omitted and that the Web may be cut into strips by the dieing mechanism.

We have alsoarranged the pressure rolls 25 and 26, the printing rolls and the dieing and scoring mechanism so that the web is maintained perfectly flat in traversing the machine and therefore the blanks as formed are smooth and Without Wrinkles.
