After itspassage from the slittingimam0 and 2 is provided and herein suitably journaled chine 12, the slit fabric next is turned over or in parallel relation on one end of a frame 3 reversed. Herein, it is passed through a series with the roll T inside the roll 1. It will also of adjacent upstanding deflecting pins 13 adaptbe observed that the fabric, which may be of any ed to reverse the fabric, although it will be undersuitable silk, cotton or other material described stood that in working on a long length of fabric in my previously mentioned patent, is fed from disposed in the machine as set forth, these pins these rolls horizontally along the frame with may in certain instances be omitted, sinceamere the fabric A from the roll 1 disposed above that manual twist once inserted in the moving fabric B from the roll 2-. It will also be noted that will be retained and produce the desired reversal 55 both fabrics A and B are acted upon by imthereof without the pins. When it is reversed,

i. e. with its previously uncoated and uninked surface then uppermost, this latter surface is then inked, preferably with an ink containing quite a little oil and being a highly fluid, liquid, oily, fast-flowing typewriter ribbon ink and adapted to enter the fibre and increase the life of the ribbon. Herein, it is passed under an ink hopper 14 preferablyof the type having a scraper 15 therein. Thereafter, the fabric is again reversed either by a series of reversing pins 16 corresponding to the pins 13 previously described, or manually. After this reversal, it next passes through a series of pull rolls 1'? and through an apertured guide 18 to the roll 4 on which it is wound with the wet surface last coated with ink toward the roll, and the surface first coated with ink retarding material and then with ink and subsequently dried, on the outside of the roll.

Next considering the fabric from the roll 2, itwill be noted that the same first passes through guides 20 corresponding to the guides '7 and under a coating hopper 21 c'0rresponding to the hopper 8 and thereafter through the same oven 9 previously described but at a point below and spaced from the upper fabric. Thereafter the fabric is also inked with a heavy bodied thick, slow-flowing ink and baked dry as previously described in connection with the upper fabric, passing under an ink hopper 22, and also likewise passed through the oven 11 under the upper fabric and substantially spaced therefrom. Thereafter, the lower fabric also passes through a slitting machine 23 similar to the machine 12 previously described and having the same function, the machines 12 and 23 herein being connected by a comon chain and driven from a single motor. Upon emerging from this machine, the lower fabric is then reversed either by means of a series of pins 24 corresponding to the pins 13 or manually, and after reversal is then inked by ink of the same character applied by the ink hopper 14, passing under a similar hopper 25 having a similar scraper.

ward into engagement with the surface of the.

upper fabric inked by the hopper 14 and wound with that fabric on the roll 4, with the wet oily, inky surfaces together and the opposite dry cellulose coated and inked surfaces of the fabrics outside and spaced from one another by the paper 5 drawn off the roll 6.

In connection with the drive of the slitting machines and rolls, it will be noted that herein I have shown the slitting machine 12 and slitting 'machine 23 to be driven from the same motor 30 beneath the frame 3 through a chain 31. It will also be observed that this chain drives a machine operated driving member 32 on the machine 12 which is rotated with a slightly faster surface speed than a corresponding member 33 driven by the chain 31. Similarly, it will be observed that the rolls 1'7 and 26 are driven froma single motor 34 and that the driving member 35 of the roll 17 is driven at a slightly faster surface speed than the driving member 36 of the roll 26. Attention is also directed to the fact that the driving members 32 and 35 are driven at the same surface speed with the rolls 33 and 36. Thus the slitting machine and rolls operating on the upper fabric operate at the same speed, while the slitting machine and rolls operating on the lower fabric also operate at the same, speed, but with a slightly lower surface speed than in the case of those operating on the upper fabric. Obviously, while this surface speed relation may be obtained by the use of separate motors as shown, it will also be evident that it'may be obtained through various different forms of driving. mechanism other than the particular separate motor and chain connections shown.

With the ribbons thus wound on the "roll 4 with their wet inked surfaces together and their dry cellulose ink retarding coated surfaces and dry inked surfaces spaced by paper, it will be evident that it is possible for the ink on the engaging surfaces on the ribbon to set in such manner as to produce a highly satisfactory ribbon, while the cellulose ink retarding coated surfaces (each having a top coat which is extremely thin, for very sharp, neat impressions of rich color and very clear, said top coat being of very dry, baked ink, which is perfectly clean and does not soil the hands) are protected by the paper. also be evident that they are very conveniently and compactly disposed in the form of a new and convenient roll on which they remain while the wet, oily, highly penetrating, liquid ink with which the body portion of each ribbon is saturated and which covers one surface of each ribbon, sets and becomes less messy and oily and smudgy. After the ink has thus set for a period of suitable length, depending upon the kind of ink used, it will also be evident that the ribbons may be separated asthey are drawn off from each roll and separatelywound, cut, and otherwise prepared for distribution and use in the manner described in my previously'mentioned patent, i. e. with the dry coated, ink retarding surface (upon which is anextremely thin layer or coating of very dry ink) of the ribbon placed against the, paper or other suitable, substantially non-absorbing material. I

As a result of my improvement, it is made possible to produce a ribbon of the new type-described in mypatent, and of superior quality, and to produce the same very economically with a minimum of attention on the part of the ma-. chine operator. It will also be observed that due to the treatment of the fabric, the same is so handled as to minimize waste or objectionable stickiness or smudging or soiling the coated, inked face while at the same time obtaining a satisfactory. coating and impregnation of the fabric with the ink retarding coating material and inks. Attention is also directed to the large production made possible with eachunit constructed and operated in accordance with my improvement. It will also be evident that the width as desired, and that the width of the other mechanism may be similarly varied in such manner as to divide the two fabrics into as many ribbons as desired of any desired width.

In Figure 4 I have shown a modified construction which may be used if desired under certain conditions, as where it is desired to use a fabric previously coated'with said ink retarding cellulose coating material or a fabric uncoated with same. In this construction it will be observed that the structure is the same as that previously described save that I have omitted the cellulose coating hopper and the oven associated therewith and shown therewith in Figure 1. In Figure 5 I have also illustrated a further modified construction also useful in connection with 1,960,647 fabric previously coated with ink retarding mathat shown in Figure 4.

The ribbons and ink transfer'members herein described, when ready for use, therefore, have ink on one face which has been thoroughly dried by means of an oven as illustrated in the drawings herein mentioned, ,and the body portion of each ribbonis fully saturated and filled with oily, liquid, fast-flowing typewriter ribbon ink. It is plain, of course, that the latter ink when first put into the ribbons makes the fabric very wet and smeary and smudgy and messy and this oily ink has to set. The dry ink described herein is an extremely thin, surface layer of ink and is simply for use to write with until the ink in the fabric (or reservoir of ink located in said fabric) begins to work through the ink retarding surface coating which lies directly underneath the said dry ink and between the large body of ink contained in the highly absorbent fabric and said dry ink, and

said dry ink is of such character as to give extremely neat writing or impressions of the utmost clearness and good color. This type of ink retarding ribbon is simply one of the kinds which may be produced more economically and more efiiciently by my new methods and with the use of my new, improved apparatus and. equipment. Other t pes of ink retarding ink transfer members may be advantageously and more economically produced by my new methods, as well as ink transfer members generally and of various types,

and kinds and I do not in any way limit myself to the ink retarding ink transfer members of my various patents.

' While I have herein specifically described three forms of my invention, it will be understood that the embodiments described herein are used for illustrative purposes, and that the invention may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.
