MACHINE FOR CUTTING, CREASING, AND FOLDING.

Application filed June 21, 1920. Serial No. 290,541;

for cigarette papers or similar articles, and

the object of my invention is to provide a machine that will perform the operations of cutting, creasing and folding wrappers in seu ence.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Fig. 1 is a front chine showing the motor and belt drive;

Fig. 2, an end elevation showing gearing,

feed table and tray for receiving wrappers after passing through the machine;

Figs. 3 and 4 are enlarged views of gearing, showing relative positions of cutters, creasers and folding rollers;

Fig. 5 is a vertical section on line AA, of Fig. 3;

Fig. 6 is a vertical section on line B-B, Fig. 3;

Fig. 7 is a vertical section on line CC, Fig. 3;

Fig. 8 is a detail view of cutters;

Fig. 9 is a detail view of the creasers; and

Fig. 10 is a diagrammatic plan view of the back of a printed shee Similar numerals refer to similar parts throughout the nine views. The body 1, legs 22, and braces 33 constitute the frame work of the machine. The motor 4, mounted on plate 5 which is secured to braces 3-3, through shaft 6 drives pulley 7, which in turn thrives pulley 8 by the belt; pulley 8 is mounted on shaft 9 which in turn drives pulley 10. The loose and tight pulleysll and 12 are driven by pulley 10 through belt drive, and. tight pulley 12 drives shaft 13, which in turn drives gear 14. Gear 14 is one of a train of nine gears on end of machine and drives crimper shafts 15 and 16 through gears 17, 18 and 19, and cutter shafts 20 and 21, and feed roller shaft 62 through gears 17 18, 22, 23, and 26. a

The lower members of the feeding, cutting, creasing, and folding mechanisms are mountelevation of-theentire maed respectively on the shafts 62, 20, 15 and 13, these shafts being mounted on the frame of the machine.

The upper members of these mechanisms are mounted on shafts 31, 21, 16 and 57 which are in turn carried by a series of pivoted arms 32, 27 and 50, so that they can all be raised, whenever necessary, upwardly from the bed portion of the machine.

The feeding mechanism comprises a driven feed roller 29 keyed to the shaft 62 and a loose feed roller 30 secured to the shaft 31 which in turn is carried on arms or brackets 32, having adjusting screws 70, the brackets being pivoted on a fixed shaft 28 mounted on the frame of the machine.

The cutting mechanism comprises upper and lower cutters 33, which as shown in Fig. 5 are held in place by washers 34 and 35, the washers 34 being keyed to the shafts 20 and 21. The cutting disks 33 which maybe of any suitable shape are held in spaced position by sleeves 36, 37, 38, '39 and 4O.

The creasing mechanism comprises upper and lower rotatable members 41and 44 as shown in Fig. 6. These members are keyed respectively toshafts 15 and 16 and are secured thereto by set screws 46, 43. The upper or male creasing member 41 is provided with a shoulder or shoulders cooperating with a corresponding groove or grooves in the lower or female creasing member 44.- The upper members of both the cutting and creasing mechanism are carried on arms27 pivoted on the shaft 28, the arms being provided with adjusting screws 56, and being secured to the shaft 28 by set screws 55.

The fglding mechanism comprises a lower member consisting of a roller 47 keyed on the shaft 13 and having preferably the shape shown in Fig. '7. The loose folding rollers 49 are mounted on shafts 57 passing through the. forward ends of hell crank lovers 50 which are pivoted on pins 52 carried in turn by a yoke piece 51 which is clamped on the shaft 28 by a bolt 61. I Springs 53 mounted on the screws 54 keep the rollers 49 pressed against the driven roller 47.

The lower rotating members of each of these cooperating devices are positively driven by the gear train shown in Figs. 2

and 3. The feed table 58 is secured to the frame of the machine by brackets 59. The receiv-' ing trays 60 are made of thin sheet metal and are mounted on the board (31 which secured to the frame of the machine by brackcts 68.

The operation of the machine is as fol lows: The wrappers are usually printed on sheets which contain a number of identical prints, as shown diagrammatically in Fig. 10. The sheets are sir: wrappers wide by seven wrappers long. lhc sheets are fed from the table 58 to the rollers 29 and 30 which feed the sheets into the machine, the folding rollers 17 and 49 acting also as feeding or delivering rollers to deliver the finished strips or wra noers into the tray 60.

As the sheet passes through the machine it is cut by the cutters 33 into strips along the lines AA (Fig. 10). The cutting strips are then. creased or crin'iped along the lines l -13 by creasers ll and 4:4; and the creased strip; than has its edge portions bent up or folded into a trough-like shape by the folding rollers 4:7 and tially folded strip delivered from the machine, is easy to completely fold, along the creased lines, after the ci arette paper packets have been inserted, this folding and filling being done either by hand or byseparate machines. The completely folded and filled strips are then cut into separate packets by cutting along the lines C-C of Fig. 10.

I claim: v

1. In a machine of the class described, the combination of means for successively cutting a sheet into strips, means for creasing the strips, means for folding the edge portions of the strips, means comprising a lower driven roller and an upper roller whichis free to revolve for feeding the sheets to the cutting means, each of said means including a lower revoluble shaft, an

, upper revoluble shaft and means for moving the upper shafts away from the lower shafts. r.

2. In a machine of the class described, the

The thus par-' combination of means for successively cutting a sheet into strips, means for creasing the strips, means for tolding the edge poi-- tions of the strips, means for feeding the sheets to the cutting means, each of said means including a lower revoluble shaft, an upper revoluble shaft and means for moving the upper shafts away from the lower shafts, said means for moving the upper shaft of said feeding means being capable of operation independent of the other shaft moving means. I

3. In a machine of the class described, the combination of means for successively cutting a sheet into strips, means for creasing the strips, means for folding the edge portions of the strips, means for feeding the sheets to the cutting means, each of said means including a lower revoluble shaft, an

upper revoluble shaft and means for moving 9 the upper shafts away from the lower shafts, said meansfor moving the upper shaft of said foldingv means being capable of operation independent of the other shaft moving means.

4:. In a machine of the class described, the combination of means for successively cutting a sheet into strips, means for creasing the strips, means for feeding the sheets to the cutting means, each of said means ineluding a lower revoluble shaft, an upper revoluble shaft and means for moving the upper shafts away from the lower shafts, means for folding the edge portions of the strips, said folding means comprising suitably shaped upper and lower members, a pivoted arm for supporting the upper member and means on said arm for applying a yielding pressure upon said upper member.

Apparatus according to claim 4 including means for adjusting thejarm relatively to the lower member, V

In testimony whereof, I aiiix my signature.

ALEXANDER e. eonnou.
