MACHINE FOR MAKING BOXFBLANKS.

Specification of Letters Patent.

Application filed March 14, 1904. Serial 110. 198,032.

To all whom it mayconcern: I

Be it known that I, FRANCIS MEISEL, a citizen of the United States, residing at Dorchester, in the county of Suffolk and State of Massachusetts, have invented a new and useful Machine for Making Box-Blanks,

of which the following is a specification.

This invention relates to a machine for printing, creasing and cutting box-blanks from a continuous strip or web of pasteboard; or similar material. I

The gener'al object of this invention is to provide a strong, compact, eflicient and simple machine which can be 0' erated at high speed, and which can be rea ily and quickly adjusted to print, crease and cut oil variable length box-blanks.

Es cial objects of this invention are to combine one or more rotary printing couples with a bed and platen-creasing mechanism; to provide devices for continuously unwinding the web from the web-roll, and for feeding the same intermittently through one-or more rotary printing couples; to provide for adjusting the web feeding mechanism to feed and deliver different lengths of boxblanks; to provide an adjustable. cutting mechanism for severing different lengths of box-blanks from the web as it is delivered; and to improve theoconstru'ction and combinations of parts throughout the machine.

In the accompanying three sheets of drawings, Figure l is a plan view of a machine constructed according to this invention.

'Fig. 2 is a side view thereof. 3 is a transverse sectional view. Fig. 4 1s a fragmentary perspective view of one of the feed ing-out rolls, and Fi 5 is a fragmentary plan view of one o the clamps showing material.

the adjustable clamp-faceswhich may be set to register with the margins between separate printed impressions. I

In a box-blank printing, creasing and cut ting off machine constructed according to this invention, as herein illustrated, the web is continuously unwound from the web-roll, and hangs in a slack loop or reservoir of From this loop of material the web is fed intermittently through one or more rotary printing couples by means of which'it is printed mono. or more colors. After being printed, the web passes between a bed and platen which cooperate to form the creases or grooves in the box-blanks. After being creased the web passes out between adjustable cutting knives which sever the web into separate products.

Referring to Fig. 3, the machine as herein illustrated comprises the vertical side-frames A. Connecting the side-frames A are the heavy cross-pieces B and C, and one or more tie-rods T.

The cross-beam B forms the bed which cooperates with a platen Pfor creasing the blanks,.and the cross-beam C forms a support from which the platen. P is operated under heavy pressure.

The side-frames A are 1 side of the machine with earingsfor the shaft of a web-roll W. From the web-roll W the material asses through the continuously running eed rolls 10 and 11, and hangs in'a slack loop or reservoir-of material from-which it is drawn intermittently as hereinafter described; From the loop or reservoir of web, the web passes between a pair of clamps consisting of the stationary clamp-jaw 12 and a movable clamp-jaw 13. Cooperating with theclamp-jaw 13 are adjustable fingers. or side-guides 14 for preventing the web from wandering or being displaced 'sidewise. From between the clamps .12 and 13 the web. asses around a feed roll 15 and between t e cylinders of the first rotary printing couple, consisting of the printing cylinder 16 and impression cylinder 17. The feed-roll 15 is normally out of contact with the impression cylinder 17, but is pressed up into contact therewith to intermittently feed the web through the first printing couple. From the'first printing couple the web passes around an adjustable register roll 18 between the cylinders of the second printing couple, consisting of the printing. cylinder 19 and impression cylinder 20.

I have illustrated a machine employing two printing couples, one for printing in one color, and the second for printing ma second color, althou h it is obvious that a Patented May 17, 1910.

rovided at onegreater or less num er of'printing couples- I can be used if desired. The printing cyllast printin couple theweb'passes around an adjustab e register roll 21, and down between the bed B and the platen P.

Secured on the face of the platen P are the usual steel creasing knives for grooving or forming the necessary creases in the boxblanks after the are printed.

One of the si e frames A of the machine is provided with an opening or slot for permitting the sidewise insertion of the creasing knives. This is most clearly shown in Fig. 2. Referrin to this figure, the side frame A is provided with a vertical slot S. At each side of the slot the frame is provided with suitable lugs or ways for receiving a heavy tie-bolt T, threaded on to which is a split nut N. 7

By means of the tie-bolt T the frame of the machine will be reinforced to stand the heavy pressure of the bed and platen, while by removing the tie-bolt T free access may btli had for'securing the creasing knives in p ace.

The connections for supporting and operating the platen P are most clearly illustrated in Fig. 3. As shown in this figure, the platen is supported at opposite sides upon rollers 22 which run on ways 23. The rollers 22 are journaled in links which are connected to short levers 24. One end of each lever 24 is pivoted to a fixed point, while the upper end of each lever is connected to move back and forth with the platen P. By means of this construction,

the rolls 22 will be moved back andforth one-half the travel of the laten P and will form efficient anti-friction earings for supporting the platen.

The platen P is moved back and forth by means of four eccentric straps 33, which engage eccentrics upon the upper and lower operating shafts 34. 1

After passing between the bed and platen. the web passes through a pair of clamps comprisin a stationary part 740 and a movable c amp-jaw 26.

The stationary part 740 is provided with a T-slot, and adjustably mounted in the T- slot are the bolts for fastening the adjustable clamp pieces 25 in different positions.

The adjustable clamp pieces 25, as most clearly illustrated in Fig. 5, may be set to different positions to register with the man gins between the printing impressions upon the web. From the clamps the web passes down between the feeding out rolls '27 and 28. The feeding-out roll 27 is journaled in fixed hearings in the side-frames, and adjustably mounted on thisroll are contact wheels 38 which alsomay beset to register with the margins between the painting impressions, as shown in Fig. i. The contact- Wheels may be fastened in adjusted positions in ordinary ways, for example, by set screws.

The gearing for driving the machine is most clearly illustrated in Figs. 1 and 2. As shown in these figures, 4O designates the driving shaft to which power may be applied by the ordinary tight and loose pulleys. Secured on the driving shaft 10 is a pinion 41 which meshes with and drives a gear 42. Turning with the gear 42 is a pinion 48 which meshes with and drives a gear 44: upon the lower operating shaft 34. The gear id meshes with and drives a gear 45 upon the upper operating shaft 34. Also driven from the gear 14 are intermediates 46 and 47. Driven from the intermediate 47 is an intermediate 18 which meshes with and drives a gear 50 uponthe feeding out roll 27. Also meshing with and driven from the gear 47 is a gear 51 which meshes with and drives a gear.52 on the first impression cylinder '1'? The gear 52 of the first impression cylinder meshes with a gear 53 of the cooperating printing cylinder 16. Also meshing with and driven from the gear 52 is an intermediate 54 which meshes with and drives a gear 55 of the second impression cylinder 20. Meshing with the gear 55 is the gear 56 of the second printing cylinder 19.

In the machine herein illustrated, the feed rolls for intermittently feeding the web through the press are held out of engagement by a cam 61 on the shaft of the first impression cylinder 1?,and are forced up into engagement by spring pressure.

As shownmost clearly in Fig. 2, the cam 61 through an arm operates aa'ock shaft (32. Extending from the rock shaft 62 are the arms in which the feed roll 15 is mounted. Extending down from'the feed roll 15 are links 63 having springs mounted thereon for raising the feed roll 15 up into engage ment with the impression cylinder 1'? when the web is to be fed through the press. The links 63 are connected at their lower ends to turn the rock shaft 6 1'. Extending from the rock shaft 6% are the links (35 for operatingthe feed roll 28 simultaneously with the feed roll 15. By means of this construction the single cam; 1 controls the operation of the'feed rolls. and by substituting different cams on the shaft of the first in ression cylinder, or by changing the operative length which meshes with and drives a bevel pinion T3 turning with a cone-pulley 74. The cone-' of the cam, the len h of the web fed forward by'the feed-r0 ls may'be'varied as req The clamps for holding the web stationary except at the time that it is being intermittently advanced by the feed-rolls in the machine, herein illustrated, are operated by a cam on the shaft of the second impression cylinder.

As shown in Fig. 2, the cam 57 operates a bell-crank lever 58. Extending from the bell-crank lever 58 is a link 59 which is connected through an arm to operate a rock shaft, mounted on which is a double sector 60. The upper section of the double sector 60 meshes with and engages a rack upon the movable clamp-jaw 13, while the lower section of the double sector 60 meshes with a rack carried by the movable clamp-jaw 26. By means of this construction the single cam- 57 controls the operation of both sets :of

clamps, and by substituting different cams on the shaft of the second impression cylin der, or by changing the operative length of the cam 57, the clamps may be opened and closed as required for variable lengths of box-blanks.

The cutting knives for severing the boxblanks from the web as they run out of the machine are operated in the construction herein illustrated by a cam on the lower operative shaft 34.

As shown in Fig. 2, the cam 66 operates a lever 67 which is connected by a link toan arm extending from a rock shaft 69. Extending down from the rock shaft 69 is an arm operating a horizontal link 70. The horizontal link 70 is adjustably connected to an arm for operating a rock-shaft 71. Extending rearwardly from the rock shaft 71 are arms connected by links to operate the vertically movable knife 30. By means of the adjustable connection with the horizontal link 70 the cutting off knives may be set to different positions according to the character of the product which is being produced. The constantly running feed rolls for unwinding the web from the web-roll.

are driven by variable speed connections.

As shown in Fig. 2, the first printing cylinder 16 is provided with a bevel gear 72 pulley 74 isconnected by belt to a second cone-pulley 75, and the second cone-pulley 7 5 is connected by bevel gears to the shaft of the feed roll 10. By moving the belt on the cone- pulleys 74 and 75 the amount of web slacked ofi fromthe web rollcan be regulated so that the supply of web will be equal to that required by the machine.

The operation of the several parts of the machine have been so fully explained in connection with the detailed description of the machine as to render a description of the operation of the machine, as a whole, un-

necessary. 7 v
