irowAnn' M. BARBER, 0E s'romne ron, CONNECTICUT, ASSIGNOR To 0. B. COTTRELL & sonsooMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

and State of Connecticut, have invented anew and useful Improvement in Cutting and Folding Machines, of which the'following is I aspecification.

The object of my invention is to provide certain improvements in cutting and folding machines whereby a plurality of superimposed narrow webs may be positivelyand accurately fed in absolute register through the sheet cutting mechanism to the folding mechanism, thus permitting the mechanisms to be run at a much higher speed than would otherwise be possible were the webs not so positively and. accurately fed.

My invention more specifically comprises twopairs of coacting endless belts driven positively by sprockets and each pair of coacting belts having an interlocking engagement, the beltsbeing so arranged that they will engage the margins of the superimposed webs, portions of'the belts being cut away for permitting the action of the knives of the cutting mechanism and the blades, of the folding mechanism.

A pmcticalembodiment of my invention is represented in the accompanying drawings, in which-' Figure-1 represents the cutting and fold- .ing machine in side elevation,

Fig.2is a front view of the machine, and

Fig. 3 is a vertical section'taken in the plane of the line AA- of Fig. 2, looking in the direction of the arrows.

v I have shown three sets of. rolls 1, 2; 3, 4; andf5, 6, arrangedtosuperim-pose six narrow webs.

The cutting mechanism'in'cludes a pair of coacting rotary cutters 7, 8 carried by shafts 9, 10, mounted in the side frames of the machine. The folding mechanism includes the male folding cylinder 11 and female folding cylinder 12 carried by their respective shafts 13, 14, mounted in the side frames of the machine. cylinder 11 is shown as provided with two sets of grip ers 15, 16, and two sets of folding blades 1%, 18. r The female folding cylinder is shown as provided with two sets of folding jaws 19, 20, arranged to coact with the folding blades 17 and 18, respectively.

The sheet delivery mechanism is herein Specification of Letters Patent.

Application filed June 12, 1915. Serial No. 33,845.

The male folding CUTTING AND FOLDING MACHINE.

Patented Sept. 24, 19 1s.

shown as'comprising the endless tape car-- guide '23, rotary dropper 24, and

riers 21,22, endless delivery carrier 25.

The cutting mechanism, folding mechanism,'and delivery mechanism may be of any well known and approved form.

The superimposed narrow websare positively fed through the cutting mechanism to the folding mechanism by two pairs of coacting endless belts 26,27, and 28, 29.

The-upper ends of the belts 26, 28, pass around a drum 30 and the lower ends of said belts pass around the male foldingcylinder 11. These belts 26, 28, are provided with holes 31, 32, arranged to be engaged by sprocket teethon the folding cylinder 11. The endless belts 27, 29, pass aroiuid the drum 33 at their upper ends and at their lower ends-they pass around sprocket wheels,

34,35, mounted ona suitable. shaft '36. These belts 27, 29,;are also provided with holes 37, 38, arranged to be enga ed b sprocket teeth on the wheels 34, 35. The pair of belts 26, 27, have an interlocking driving engagement by providing one ofthebelts with pins 39 arranged to enter corresponding holes 40 in the other belt. Similarly, the belts 28 and 29.have an interlock- 1i)ngengagement by providing one of the e ts cylin'derll that the pairs of belts will trav el" together from the drums 30, 33, downwardly through the rotary cutters 7, '8 toflthe folding cylinder 11 and from thencea short distance 'a-long the-periphery'of the folding cylinder before the belts 27, 29, are permits ted tov separate from their corresponding belts 26, 28. This permits the grippers 15 and 16 to have ample time 7 on the advance edge of the webs while the webs are being held in register on the periphery of the folding cylinder 11 thus permitting the mechanism to be run at a much higher speed than would otherwise be pos- S1 e.

Gearing 47, 48, 49,50, 51, 52, 53, 54,

56, 57, 5s, 59, e0, 61, 62,63, 64, e5, 66, prowith pins 41, arranged to enter cor respondlng holes'42 in the other belt.-

to close gently narrow webs through the cutting mechanism to the folding mechanism where the advance edges of the webs, while held in register by the belts, are engaged by either the set of grippers 15 or 16.

At about the time the grippers engage the webs, the cutting mechanism operates to sever the same and the sheets are then car ried around the periphery of the cylinder 11. until the folding mechanism wants to fold off the sheets to the cylinder 12, from which cylinder the sheets are delivered by the tape carriers 21, 22, guides 23, and sheet dropper 24:, to the delivery device 25.

It will thus be seen that the narrow webs are positively fed through the cutting mechanism to the folding mechanism in accurate register and held in such register a sufiicient time on the male folding cylinder to permit the easy operation of the grippers.

A divisional application has been filed on the 16th day of October, 1915,'Serial No. 56252, covering the cutting mechanism, and no claim therefor is made herein. except in connection with the folding mechanism.

It is evident that slight changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein set forth, but

hat I claim is 7 1. In a machine of the character described, a cutting mechanism, a folding mechanism, and means for positively feeding a plurality of superimposed webs through the cutting mechanism to the folding mechanism, said means comprising coacting positively driven endless belts having an interlocking engagement.

2. In a machine of the character described, a cutting mechanism, a folding mechanism, and means for positively feeding a plurality of superimposed webs through the cutting mechanism to the fold ing mechanism, said means comprising 00 acting endless belts having an interlocking engagement and sprockets for positively driving-the belts.

3. In a machine of the character" described, a pair of coacting rotary sheet cutters, a folding mechanism, and means for positively feeding a plurality of superim posed webs to and through the cutters to the folding mechanism, said means compris- 7 gaging the margins of the webs, each pair of bolts having an interlocking engagement.

5. In a machine of the character described, a pair of rotary cutters including enacting cutting blades, a rotary folding mechanism including coacting folding blades and jaws, and means for positively feeding plurality of superimposed webs through the cutting mechanism to the folding mechanism, said means comprising two pairs of positively driven endless belts engaging the margins of the webs, said belts having cutaway portions for permitting the cutting blades to act upon the full width. of the webs and the folding blades to act upon the full width of the sheets cut from the webs." 6. In a machine of the character described, a cutting mechanism, a folding mechanism including a cylinder and its grippers, and means for/positively feeding a plurality of superimposed webs through the cutting mechanism to said grippers, said means comprising coacting positively driven endless belts arranged to hold the sheetsin register on the said cylinder prior to the closing-of the grippers.

In testimony that I- as my invention, I have signed my name this tenth day of June,cl915.

HOWARD M. BARBER."
