Specification of Letters Patent.
Patented Nov. 19, 1918.
Original application filed June 12, 1915, Serial No. 33,845. Divided and this application filed October 16, 1915. Serial No. 56,252.
To uZZ whom it may concern:
Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Cutting and lFoldin Machines, of which the followlng is a specification.
The object of my invention is to provide certain improvements in cutting and folding machines whereby a plurality of superimposed narrow webs may be positively and 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 two pairs of coacting endless belts driven positively by sprockets and each pair of coacting belts having an interlocking engagement, the belts being 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 practical embodiment of my invention is represented in the accompanying draw ings,'in which,
Figure 1 represents the cutting and folding machine in side elevation,
Fig. 2 is 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.
I have shown three sets of rolls 1, 2; 3, 4; and 5, 6, arranged to superimpose six narrow webs.
The cutting mechanism includes 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. The male folding cylinder 11 is shown as provided with two sets of grippers 15, 16, and two sets of folding blades 17, 18. The female folding cylinder is shown as provided with two sets of folding jaws 19, 20, arranged to eoaot with the folding blades 17 and 18, respectively.
The sheet delivery mechanism is herein shown as comprising the endless tape carriers 21, 22, guide 23, rotary dropper 24, and endless delivery carrier 25.
The cutting mechanism, folding mechanism, and delivery mechanism may be of any well known and approved form.
The superimposed narrow webs are 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 teeth on the folding cylinder 11. The endless belts 27, 29, pass around the drum 33 at their upper ends and at their lower ends they pass around sprocket wheels 34, 35, mounted on a suitable shaft 36. These belts 27, 29, are also provided with holes 37, 38, arranged to be engaged by sprocket teeth on the wheels 34, 35. The pair of belts 26, 27, have an interlocking driving engagement by providing one of the belts with pins 39 arranged to enter corre sponding holes 40 in the other belt. Similarly, the belts 28 and 29 have an interlocking engagement by providing one of the belts with pins 41, arranged to enter corresponding holes 42 in the other belt.
The belts 26, 27, 28 and 29 are provided along their inner edges with recesses 43, 44, 45, and 46, respectively, for permitting the operation of the cutting blades and folding blades across the entire width of the belts.
The sprocket wheels 34, 35, are so arranged with respect to the male folding cylinder 11 that the pairs of belts will travel together from the drums 30, 33, downwardly through the rotary cutters 7, 8, to the folding cylinder 11 and from thence a short distance along the periphery of the folding cylinder before the belts 27, 29, are permitted to separate from their corresponding belts 26, 28. This permits the grippers 15 and 16 to have ample time to close gently 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 possi le.
Gearing 4:7, as, I9, 50, 51, 52, 53, 5a, 55, 56,157,58, 59, c0, c1, c2, 63, Get, 65, 66, provide means for driving'the several mechanisms at the proper relative speeds. Guides (37, 68, are provided for guiding the webs from the cutting mechanism to the folding mechanism. 7 r
In operation; the narrow webs passing over the rolls 1, 2; 3, 4; 5, 6; are superimposed at the drums 30, 33, and are engaged at this point along their marginal edges by the two pairs of endless belts 26, 27 and 28, 29; These belts convey the superimposed 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 carried around the periphery of the cylinder 11- until the folding mechanism coacts to fold 01f the sheets to the cylinder 12, from which cylinder the sheets are delivered by the tape carriers 21, 22, guides 23, and sheet dropper 2%, 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.
Claims'directed to the combination of the GopieI mechanisms are presented in my orlginal 12, 1915, SerialNumber 3384M), of which this application is a division.
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 invent-ion; hence I do not wish to limit myself strictly to the structure herein set forth, but
WVhat I claim is:- r
1. In a machine of the character described, a pair of coacting rotary sheet cutters, and two pairs of positively driven endless belts overlapping the marginal edges of a plurality of superimposed webs to positively feed the webs to, through and beyond the cutters, each pair of belts having an interlocking engagement.
2. In a machine of the character described, a pair of coacting rotary sheet cutters including the cutting blades and two pairs of positively driven endless belts overlapping the marginal edges of a plurality of superimposed webs to positively feed the webs to, through and beyond the cutters, said belts having cutaway portions for permitting the coaction of the cutting blades across the entire width of the webs.
In testimony, that I claim the foregoing as my invention, I have signed my name this 15th day of October,'1915.
