Application filed-January 3 1 1925. Serial No. 6,127.

This invention relates to cutting andscormg presses. I I

An object of-the invention is to provide-a press with cutting and scoring unit provid-. mg for variations of outllneof cuttin'gand scoring as may-be deslred. My ln'ventlonfis particularly applicable to cutting andscor ing units of theeylindrical or other arcuate shape andcoactingwith a correspondingly shaped mpression cylinder for use ma ro tary press.

Pursuant to my invention, the shell of wood or other s-uitablekmaterial issevered along theoutline'sof cutting and scoring by;

cutting. or'scoring rules; respectively disposed between and held at the lines 'of 'severing of the shell. The shell ispreferably-built up of partial cylindrical or other arcuate portions and locked with the cutting an'dseoring rules tow a turtle orother suitable removable support on the cutting and scoring cylinder roll.

The built-up assembly is .arrangedior all I shapes or lengths oflbla'nks cut/ from the-web by thefus'e of removable turtles ofwaryingn outer diameters the inner diametersbeing substantially uniform and conforming to the outer diameter ofthe cutting and scoring cylinder roll.

Further features and objects of the inven-- tion will be more fully understood from the= following. detail description and the-accompanying drawings} in which Fig. 1 1s aPGISPBCtIVG VlGW of a rotary press including the usual pr ntingoracolor impression rolls, and provided with acutting and scoring un t embodying nynvention; this figure shows the press as a as viewed from its feeding end;

It will be observed from Fig. 3 that the group of cutting and scoring rules corresponding to each individual blank is duplicated lengthwise of the cylinder and also circumferentially of the cylinder 20 for the purpose of attaining a maximum number of groups of cutting and scoring rules about the periphery of the cylinder 20 and to minimize the waste of the web. The cutting rules are provided with sharpened edges serving as knives in coaetion with the impression cylinder 21, and extend from the axis of the cylinder 20 radially sufliciently to fully sever the web. whereas the scoring rules are of a. construction similar to the cutting rules, but of lesser radial extension relative to the axis of the cylinder 20. In Fig. 3, the cut outline of the blank is illustrated in full outline as indicated at 33 and the scoring outline is illustrated in (lash outline as indicated at 3%. The printing 35 is varied, as will be understood.

A preferred method of forming the strips 30 of the cutting and scoring shell 22 is illustrated in Figs. 6 and 7, the subject matter of which forms a separate application filed by me under date of January 31st, 1925, Serial No. 6,128, bearing the title of Method and means of forming cutting and scoring units. In general, the lines of cutting of the unit 22 are substantially radial relative to the center of the turtle 23, that is, to the axis of the cylinder 20. Comparing Fig. 6 with Fig. 3, the cutting rule 36 provides for the particular line of cutting 37 of a blank 29. It will be noted that the cutting rule 36 is positioned against the face 38, see Fig. (3, of a strip 30. The cutting rule 39 provides for. the particular line of cutting 40 in a blank 29 and is positioned against the face 41, seeuFig. 6, of a particular strip 30. The lOClllIl'gnOfirtllB cutting rules 36, 89 against the respectiv enfaces 3S, atl is attained by the shorthstri-p; (unblock 42 having its faces 43, 4.4 cu torakl ialtly. {like block 42 is secured in position on thelturtlehfil?) by means of screws 45 entire; l ike passing; through the perforationsAfi'nthe screws-{tinnedapped within the tianeaded openings d7 in' the turtle 23, or q a mrwam eiiheadsaafiz hoiii nt x6 a iqpr itarably nou tcne mkbto hire-1 ose atilaou nani eu iqar s qiirtluvs sav lected of convenient lengths corresponding to the outline of cutting of the blank. As is indicated in Fig. 6, the body portion of each cutting rule is of substantial thickness; the body portions of the cutting rules are of substantially uniform thickness. The scoring rules are of similar uniform thickness but their knife edges are of lesser radial height and rounded or relatively dull. Isually the rules are selected of lengths of the respective straight-line or rectilinear portions of the outline of the blank and of the corners and of the curved portions of the outline of the blank.

As one convenient procedure of cutting the strip 30 of the cutting and scoring shell 22, I employed the device illustrated in Fig. I and comprising an endless band saw (i guided and driven in the usual manner and passing through the slot 61 extending through the fixed standard 62 of the device. The standard 62 is supported at its lower end on a bench or table provided with a slot similar to the aforesaid slot. (31. At the upper end of the standard 61 is mounted the base 63, rotatable horizontally. At the opposite ends of the base 63 are brackets 65 which are provided with a l'iearing 6 (one only being shown in Fig. 7) for respectively receiving the bearing studs (37 of the idle, supporting cylinders 68, (59. The diameter of the supporting cylinders 63, (39 corresponds to the inner diameter of the strip 31 or the outer diameter of the turtle 20. l'ihen it is desired to cut a shell strip 30, the des red out-line of the blank is pencilcd or otherwise marked as indicated at TO by the dash and dot marking line on the upper surface of a shell strip 30 and the cutting by the band saw 60 begun by bringing the extreme edge 71 of the marked outline into engagement with the cutting edge of the l and saw 60. The line of cutting at the extreme edge 71. is therefore radial. by reason of the corresponding axis of the arcuat'e shell strip 30 and of the supporting c vlin ders G8, (39. The portion '72. see Fig. 7, of the marked outline 70 is rectilinear and a cordingly its cutting is attained by sliding the shellstrip 30 over the supporting cylinf ders GS, 69 without rolling the cylinders (39, (it) and without turning the table 63. The portion 73 representing a corner in the line of cutting and of the marked outline T0 is effected by jointly rolling the shell strip 3 i on the supporting cylinders (33, 69 and horizontally rotating the table 63. The portion to sllhflil'nfiglgdijifififilaiwylilfln1}}l K3lQW t:l?Q,}1p- 74t of the line of cutting is rectilinear and pen surface of its strip 3 ln n gsunalar substantially at right angles to the aforec s oam iaaaer capoad na manne (relat re tOdi 1Btlpi 0=ll tfll fiiltlut-lfl 23; i

The cutting rules are advantageously so 'lSFUd portion 72; the line of cutting along the pprtigia 'ia is attained by rolling the shell 5t,r 1p,0,,o;;er the supporting rolls 68, 69, in the direction of the arrow 75 while keeping 1,, u, tl e table (ifsubstantially quiescent. In a similar manner, the remainder of the cutting of the ifiarkedoutline 70 is carried out by similar operations.

By the provision of the adjustable bearings 24, 24 of the cutting and scoring cylinder 20 and the corresponding adjustable bearings 28 for the impression cylinder 21, each set of combined turtle 23 and cutting and scoring shell 22 of the different diameters is accommodated on the same press and the straight line travel of the printed web 17 provided for. For any cutting and scoring cylinder 20 of a given diameter, a set of turtles of varying thicknesses and uniform inner diameters are provided respectively for the made-up cutting and scoring shells 22 of varying outer diameters.

Preferably, the press is provided with suitable gearing for interconnecting the cutting and scoring unit with its impression cylinder and controlled by the hand wheel 80, see Figs. 1 and 2, for advancing or retarding the cutting and scoring cylinder 20 relative to the printing or other impression on the web for registering purposes. In a similar manner, the printing or off-set couple or couples are interconnected by gearing, controlled by the hand wheel 81 for advancing or retarding the printing or other impression lengthwise of the web for corresponding registering purposes.

From the above, it will appear that my invention provides for the assembly of cut ting or scoring units or both on cylindrical or other arcuate mounting means, and affords variation of contour of cutting or scoring or both as may be desired.

Pursuant to my preferred procedure or forming the cutting and scoring unit, the body portions of the cutting and scoring knives are rules of flat stock of uniform thicknesses and the cutting and scoring edges of simple tapered formation, affording ready making up of the knives for all variations of outline of the desired cutting and scoring.

By the use of my invention, the output per unit of time is materially increased. My invention is wholly adapted to be directly attached to rotary and similar presses, and

thereby attaining the desired cutting and scoring of the web as well as the printing or coloring or both by substantially a single operation.

By reason of the composite or made-up character of my cutting and scoring shell, the component strips are of relatively short arcial lengths, thereby enabling in practice the use of strips of substantially uniform inner and outer radii of curvature respectively as well as of uniform thickness, not withstanding that the resulting shells are of different inner and outer radii of curvature.

The particular cut and scored outline of the blank illustrated in the drawings is that of a carton for a bar of soap, and it will be understood that the invention is also adapted for forming other out and scored products such as egg boxes and the like, hearing such printed or colored impressions as may be desired.

lVhereas, I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may he made without departing from the spirit of the invention.
