CUTTING-ROLL;
Specification of Letters Patent. -Pa,i ented A -.11, 1916 Application filed November 6, 1914. Serial No. 870,585.
i i To all whom it may concern:
. Be it known that I, RUSH BURTON, a citizen of the United States, and a resident of New Brunswick, in the county of MiddleseX and State of New Jersey, have invented a new and Improved Cutting-Roll, of which the following is a full, clear, and exact description.
The invention relates to cutting rollssuch as are used in paper border-cutting machines for cutting the edge of the paper in conformity to the contour of the imprint on the P r- I The object of the invention is to provide a new and improved cutting roll of the type mentioned, in which the steel cutting knives are set or driven into the peripheral face of a wooden core, the core having metal foundations for the backs of the knives to rest 'on,,so that the knives are held against inward movement, thus maintaining the cutting edges of the knives in true circular shape. 1 e
In order to accomplish the desired result,
use is made of metallic foundations set inv the core under the backs of the knife sections for the latter to rest on.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 1s a slde elevation of a cutting roll provided with the improvement; Fig.
2 is a perspective view of a portion of the wooden core, one of the knife sections, the foundation for the same, and the plugs for closing the recesses containing the foundations, the parts being in disassembled position; Fig. 3 is an enlarged cross sectionof the cutting roll on the line 33 of Fig. 1; Fig. 4 is a longitudianl section of the same on the line 44 of Fig. 3; Fig. 5 is a perspective view of one of the foundations; and Fig. 6 is'a similar view of a modified form of-one of the foundations.
In the construction of cutting rolls employed in border-cutting machines, use. is made of a wooden core and knife sections set or driven in the peripheral face of the core to provide an annular cutting edge conforming in shape to the contourof the imprint on the border, the latter passing between the cutting roll, and an imprint roll cuttingedgeQ As the knife sections extend all around the peripheral face of the wooden core they are. liable to be pressed inward when subjected to any heavy pressure incident to the trimming operation of the border at the time the latter passes between the cutting roll and the imprint roll. It is obvious that some of the knife sections extend across the grain of the wood and hence the inward moving tendency of such knife sections is not very pronounced, but knife sections which are otherwise disposed relative to the grain of the wood, especially those that extend in the direction of the grain of the wood, are liable to'be pressed inward a considerable distance so that the continuous cutting edge instead of being truly circular is seriously disturbed, that is, is rendered irregular and consequently the border is not properly out along the contour of the imprint, that is, portions of the paper remain uncut. In order to prevent the knife sections from unduly sinking into the wood of the'core, use is made of means, presently described in detail, by which the continuous cutting edge of the roll is maintained at all times in true circular shape.
As shown in the drawings, the wooden core A of the cutting roll is mounted on a shaft B, and in the'peripheral face of the said core are set or driven steel knife sections C along a guide line D conforming in shape and arranged according to the contour of theimprint of the paper to be trimmed. The core A is provided with recesses E, preferably, formed by radially boring into the peripheral face of the'core A at the junction. of adjacent knife sections, and intermediate the ends of some of the knife sections in case the latter are of considerable length. In the bottom of each recess Eis placed a plate F, preferably of steel or other similar material, the said plate forming a foundation for each knife section to prevent the latter from being pressed inward in the core A when subjected to pressure, as previously explained. I It is understood that the recesses E and the foundation plates F placed therein are disposed in the peripheral face of the roll according to the line of the knife sections, so that'when the latter are set or driven into position in the peripheral face of the core A then the backs of the knife sections finally are seated on the plates .F. After the plates F are placed in position in the recesses E, the latter are filled in by Wooden plugs G. The recesses E may be formed throughout the length of each knife section, and in this case a correspondingly shaped plate F is placed in the bottom of each recess to form a foundation for the back of the corresponding knife section. It is understood that the plates F, F form a broad foundation for each knife section to rest on so that the knife sections are not liable to be pressed inward in the core when subjected to pressure. In practice, the knife sections are driven into the core A and then the outer ends are ground to form a cutting edge Which is truly circular.
It is understood that WhQIl'tlle knife sections are driven home in the core, portions of the backs of the knife sections rest on the solid foundations and the remaining back portions rest on the material of the core. The plugs G driven into the recesses E after the knife sections have been driven in, are internally split When driven home.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
