BEVELING MACHINE Filed Jun so, 1950 INVENTO Patented May 19 1931 UNITED STATES DANIEL W. B. KURTZ, JR, OF- BALTIMORE, MARYLAND BEVELING MACHINE Application filed June 80,

This invention relatesto improvements in the manufacture I and formation of index cards and the like, and has for its object to provide means whereby such cards and the like may be beveled on all the edges and on both sides thereof.

Another object of the invention is to provide means whereby index cards and the like may be beveled on their edges in the same operation with the cutting thereof.

Another object of the invention is to provide a machine which will first bevel the cards and the like on the lines where they are to be cut, and then cut the same on said lines as at the junctures. thereof.

A further object of the invention is to provide cards and the like beveled on both sides and around all the edges thereof.

A still further object of the invention is to provide a means whereby sheets of paper,

leather and of other pliable'material may be beveled without cutting away any of the material thereof, which process weakens the edges of the sheets, and by compressing the as material of the edges into smaller spaces thus compacting and hardeningit and hence rendering the edges of the sheets more durable.

With the above and such other ob'ects in view as may be more fully hereina ter described, I have invented the device illustrated in the accompanying drawings which are hereto attached and made a part hereof.

In the specifications the device is described as it should appear for the purpose of double beveling, but I do not restrict my invention only to double beveling, because by using only one die opposed by a smooth roller the device is equally as effective for single beveling when this is desired.

Figure 1 is a front elevational view of a set "of beveling dies made according to my invention.

Figure;2 is a side elevational view of a beveling and cutting machine embracing my invention.

Figure 3 is a card longitudinally beveled and cut in said machine just before passing transverselyand the second timebe-.

tween the dies and the cutting-rollers for com leting the making of the card.

Flgure 4 is a plan view of a card made on said machine.

Figure 5 is an edge view of a stack of said cards, viewed from either" the side or the end edges of the stack. v

Like reference characters indicate like parts throughout the specification and in the several views of the drawings, in "which 1 indicates parts of a machine embracing my invention, including

rollers

2 and 3 for carrying beveling dies 5 and 6, and rollers 7 and 8 carrying cutting dies 9 and 10. The rollers 11 and 12 are card pulling rollers which draw the completed cards through the machine. Each of the beveling dies and 6 consists of collars 14 having centrally disposed

bevels

15 and 16 terminatin in a narrow annular flat surface 167 on tie exone side of the card section 19 of the stock 3 20, and other dies (not showing) similarly placed on said rollers will form-the bevels 18 and 22 on the opposite side of the card; section. After passing through these beveling dies the stock 20 1s drawn between the cutting dies 9 and 10, which are positioned to cut on an exact line with the peri heries 16 of the beveling dies. The stoc runs first through the machine to bevel and cut it into strips, bein beveled along the two edges 24 and 25 o the cards, 26, and then the strips, when run again through the machine, to sever the cards entirely, are beveled along the

edges

27 and 28 of the cards, thus com leting the operation of beveling the car s on both sides of allfour ed es. This double beveling of the cards, that 1s on both sides of all edges, will permit of stackin the cards quickly and correctly, and will e iminatewaste of time at rearranging them in case the cards should become disarranged; whereas if the cards were beveled only on one side thereof, as indicated in myPatent No. 1,? 55,961, in an disarrangement of the cards, through acci entally dropping them,

considerable time must be taken to arrange them with the bevels all in one direction. Also a beveling of the edges of cards or other sheets for any purpose, by this method of compressing the material, instead of cutting away a portion of it to form the bevels, strengthens the edges and thus adds longevity to the durability of the sheets.

The purpose of the flat peripheries on the dies is to give, to the creases the dies make in the stock a fiat bottom sufiiciently wide for the slitter blades to travel in without encroaching upon the beveled side Walls of the creases.

The invention is applicable to slitters with cutting blades of any desired shape such as the straight blade slitter called the guillotine and the slitters with rectangular cutting dies having round corners for stamping out playing cards, by giving to the creasing dies the same shape as that of the cutting blades to be used.

Having now described my invention, that which I claim to be new and desire to protect by Letters Patent is: v

1. In combination with a pair of rotary beveling dies, said dies opposingly arranged, said dies having flat peripheral edges in cross section of relatively narrow width, said dies having beveled side walls terminating at said flat peripheral edges, said dies.

adapted to bevelv two edges of a card at one operation, rotary slitting dies disposed adjacent the beveling dies in tracking relation thereto for severing the stock in the trough 3f the creases produced by the said beveling 2. In combination with a pair of beveling dies, said dies opposingly arranged, said dies having fiat peripheral edges in cross section of relativel narrow width, said dies havin beveled si e walls terminating at said at peripheral edges, said dies adapted to bevel two edges of a card at one operation, cutting means disposed rearwardly of said dies and adapted to sever the stock in the trough of the creases produced by the said creasing dies.

In testimon whereof I afiix my signature.
