To all whom 'it may concern.: n
Be it known that I, (.)zms IAQUIN, a c1t1- zen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Rotary Cutting Devices, of which the following is a full, clear, and exact description, reference bein had to the accompanying drawings, forming a part of this specification.
My invention relates to a rotary cuttin device of the type whereby a moving we of material may be eut into sheets of, a predetermined length. In euttingdevlces of this type, a positive and even severance of the web of material without, leaving some fibers unsevered ditlicult to secure, due to the rapid dulling of the cutting edge of 'the knife, owing to the great pressure in forcing the entire cutting edge against an abutment whereby the material is severed; or by reason of the irregularity in outline of the plane of its cutting surface. l
An object of my invention is to produce a rotary cutting device that will always be positive in its cutting action, produce a cornplete severance of the fibers of the material and revent clogging of the machine caused by t e failure to sever some of the fibers along the line where the out is made.
Another object of my invention is to produce a rotary cutting device of this type whereby only small sections of the rotting edge of theknife are engaged in sequence in cutting artico along a line substantially at a right angle to the path of traelpf moving web of n'iateldal thereby obviatmg the necessity- :if requiring the full pressure to be brought, instantaneously upon the entire cutting surface upon the abutment against which it is :nlapted to press.
In its specific application. my 'invention is attachable to printing presses so that 1t will operate with a positive cutting action on a moving web of paper, thereby severing the web into sheets of' any predetermined length having perfectly smooth edges at the line of severance.
Figure l is a lop or plan View of my rotary cutting devine.
Fig. Il is a side elel i vallon. l' ig. lll is a rear elevation. partly i in section. Fig. lV is a side elevation,
partly in section. Fig. V is a (op or plan view ol' the ,cutting members showing then knife in operative condition.
lfig. Vl is an enlarged detail view partly in vertical section showing the cuttin members in `operative position. Fig. VI is a vertical section taken approximately on line VIL-VII, Fig. VI. Fig. VIII is a. vertical section illustrating a modification.
vIn the accompanying drawings :WA designates a web of paper arranged between "a pair of feed rollers 1 and 1 having their journals 2 andI 2 mounted in adjustable bearings 3.
4 designates a rotatable knife carrier, preferably in the form of a roller provided with a longitudinal recess 5, within which a knife (l is slidably mounted. `Removable plates 7` constitute the end walls of the recess 5 and serve as stops for limiting the outward movement of the knife, the latter having retaining lugs 8 at its ends which extend into apertures in the plates 7. The 'knife is yieldingly held in position for engaging the paper by springs 9 interposed between the inner edge of the knife and the heads of the screws 10,(see VI and VII ,said screws being ad'ustably mounted in t e knife carJ rier. A ar 11 carried by a roller 12 forms an abutment for the spring pressed knife during the cuttin operation. The knife carrier 4 and rol er 12 are sup orted by bearings 13 adjustably mounte on the frames 13 and they are caused to move in unison with the feed rollers b a train of gearing which will be present y described.
I4 designates a drive member, preferably .a sprocket chain, meshing with a sprocket 15 on the journal at one end of the roller 12. The journal at the opposite end of the roller 12 is secured to a gear wheel 16 meshing with a gear wheel 17 on the journal ofthe knife carrier 4, (see Fig. VII). The gears 16 and 17 cause the roller 12 and knife carrier 4 to move in unison and through the medium of an idler 18 the gear wheel 16 imparts rotary motion to gears 19 and 20 which drive the feed rollers 1 and 1.
In the operation of my improved paper cutter, the web of pa er A is fed between the knife carrier 4 an roller 12 by the feed rollers 1 and 1 and during each revolution of the knife carrier the paper is severed by the cooperation of the cutting edge of the knife and the abutment 11.
It. will be seen that the axis of the rotatable knife carrier 4 is inclined to the path of travel of the paper and that the knife 6 is inclined to the axis of the carrier, the knife being positioned so as to lie substale tially at a right anglo to the path of travel of the paper when it performs the cutting operation. (see dotted lines in Fig. The axis of the roller 1Q provided with the rotatable abutment il is parallel to the axis of the knife carrier. lly inrlining the eutting members, as just deseribed, the knife is spirally located on its earrier. and when brought into cooperation with the abutment 11, it produces a positive vatting action. gradually .severing the paper smoothly yon a. line at right angles to the path ot travel of the paper. During this cutting operation, the web of paper continues' to move in the direction indicated by the arrow in F ig. l, and the knife begins its cutting aet ion at the edge of the paper marked a. lt must be borne in mind that the paper and the eutting edge of the knife move at the same speed, and while the cutting is perforl'ned on a dia onal line, the paper is properly advanced uring the cutting operation to produce an absolutely smooth and true severed edge at right angles to the side of the paper; z'. e., at right angles to the path of movement of the paper.
The knife carrier 4' shown in Fig. VIII is provided with' a pair of knives 6 and springs 9 for forcing said knives into engagement vwith the paper without undue rietion, thereby preserving the cutting edge of the knife. Spring Seats 25. engaging the inner ends of springs J may be adjusted to vary the pressure of the springe by a wedge 26, the latter being adjnstably eouneeted to a screw 27 rotatably mounted in a rigid late 2S. The rotatable abutna-nt earrier l2 1s provided with a pair of abutuauts il which eotiperate with the knives tl'.
It is obvious thatr my invention is also capable of being used to pei-forato a moving web of paper at predetermined intervals; simply by substituting a knit'e having perforating points instead of e blade with a continuous edge.l or by adding a perforator to the cutting device, thus perfor-ating and cuttin at. the I#ame time, when desired.
.While I have described my invention as applied to cutting a moving web of paper, it is obvious that it could be used for eutting any other material, such as cloth, felt, leather, ete., into lengths in a manner similar to that in which it operates upon paper.
I claim:
