Patented Dec. 25, 1934 mansrnnnma mmrns Joel F. Sheppard, Dover, N. E, aaaignor to 11.1. M. Kidder Press Co. Inc.) Dover, N. 11., a

corporation of Delaware A p ication December 13, 1932, Serial Nam-1,002 a (01. 242-55) This invention relates to a functionally and structurally improved transferring apparatus by such apparatus.

It is an object of the invention to provide an apparatus of this nature in which, for example, a delivery roll is placed in association with the machine and the material is slitted and distributed to one or more receiving spools or shafts:

By means of the present invention it willbe found that the coils of received material are distributed in such manner that they are capable of separation from each other without danger of mutilation, and that, moreover, where readily desired, the web strips comprising the separate material ribs are of uniform width.

A further object is that of providing an apparatus of this nature which will embody relatively few parts, each individually simple and rugged in construction, and capable of assemblage to furnish a-machine operating over long periods of time with minimum of manual attention and freedom from difliculties.

Referring to the annexed drawings, there has been illustrated two practical embodiments of the invention, and in these drawings Figure 1 is a side view of one form I machine;

Figure 2 is an end view thereof, and

of the Figure 3 shows a slightly different form of apparatus.

While the present machine is primarily intended for use in connection with the slitting and transfer of material webs, such as paper, transparent cellulose, cloth, etc., it will be appreciated by those skilled in the art that the teachings of the invention might readily be embo a transferring and printing machine.

died in of disks 9 for cooperation with shearing cutters 10. The standards 6 may also support guide rolls 11, 12 and 12', and if a plurality of receiving rolls are employed, additional guide rolls 13 may also be mounted by the standards. 5 mounts or provides track portions 15 an and 14 The base d16,to

each side of the standards 6. Mounted upon the former is a carriage 17 supporting a mill roll shaft 18. It is, of course, obvious that this carriage might have any desired height with respect to an adjacent supporting surfaceso that a minimumeffort will be required to bring the mill roll to position thereon.

Mounted upon the track portion 16 is a second carriage 19. In the embodiment under consideration, two receiving rolls 20 and 21 are mounted by this carriage, and synchronous movement of these rolls is assured by, for example, a gear train 22. It is obvious, however, that if desired, the carriage 19 might. merely mount a single receiving roll, in which case the apparatus could be simplified accordingly. In any case it is preferred that the web or strips of material fed through the machine be moved incident to the fact that they are secured to one or more receiving rolls which may in turn be power driven by a motor 23.

Referring to Figure 3, it will be noted that the base 5 provides or mounts a standard 25 which is fixed. This standard mounts one .or more receiving rolls, as I heretofore described. However, in-this form of the invention, the central portion of the base mounts or provides track portions 26 upon which is movably mounted a carriage 27 carrying parts corresponding to those which are mounted by the standard 6 in Figures 1 and 2. In addition, one end of the base mounts or provides trackportions 28 upon which there is movably mounted acarriage 24 which supports the mill roll shaft 18, as heretofore described.

Referring again to the first figures, it will be understood that a mill roll is positioned upon the carriage 17 and that the web is threaded around the guide roller 11, then over and around the roll '7, and thereupon under and around the roll 12. If a single receiving roll is employed, the web merely passes over and around the roll 12" and thence to the roll 21. If, however, a second receiving roll is utilized, certain portions of the web will be disposed in the manner aforenoted, but others of the same will pass only partially around the roll 12 and will then transfer to the roll 13 and'over and around the roll 14 and the roll 20.

If a set-up of apparatus such as has been illustrated in Figure 3 is utilized, the parts are threaded in precisely the same manner as heretofore noted, it being observed, however, that while, as shown in Figures 1 and 2, the carriages 1'7 and 19 are shifted or permitted to move toward the standard 6, in the structure illustrated in Figure 3, the carriages 24 and 27 may shift with respect to the standard 25. In both instances the cutters or other apparatus supported by the standard 6 or carriage 2'7 are properly set up and the machine is now ready for operation.

In both forms of the invention it will be observed that the web or material strips are supported substantially constantly in their travel from the material roll to the receiving roll or rolls. In other words, there are substantially no gaps between the supporting surfaces. As a consequence of this construction, it has been found that any tendency of the web or strips to weave is virtually iorestalled. In the structureshown in Figures 1 to 3, it is obvious that as the motor.

23 beginsto operate, the carriage 17 or 24 as the case may be-due to frictional drag--will shift to a position at which the last convolution of the material on the mill roll will be in intimate contact with the guide roll 11 and this will be true throughout the entire operation, and despite the decreasing diameter of the mill roll, as the material is unwound from the same. Also, incident to the drag of the material the carriage 19 01' 2'7 will shift to positions at which the receiving roll will be constantly in intimate contact with the last guide roll. 01. course, it the construction shown in Figures 1 and 2 is employed, the tensioning rolls 12' and 14 will be in contact respectively with rolls 21 and 20. It will be appreciated that. regardless of this factor, however, as the receiving roll or rolls build up incident to the increasing number of material convolutions upon their bodies, the carriage 19 will be free to shift outwardly without, however, in any sense of the word affecting the fact that there will be no gaps or spaces within which the material web or strips are unsupported.

In the case of apparatus such as shown in Figure 3, the carriage 24 will shift increasingly toward the guide roller 11 as the convolutions oi. the mill roll decrease in number, and likewise the carriage 27 will shift increasingly away from the receiving rolls 20 and 21 as the diameters of these rolls increase. 1

Thus, among others, the several objects of the supporting said operating means to reciprocate with respect to said receiving roll, whereby to substantially constantly support the material in its movement from one roll to the other.

2. A transferring apparatus including a base,

track portions associated with said base and ex tending substantially horizontally, carriages mounted upon said track portions, a delivery roll mounted by one of said carriages, material manipulating rolls mounted by the other of said carriages, a support fixed with respect to said base, a receiving roll carried by said support and a motor coupled to said receiving roll, whereby a web of material extending from said delivery roll through said operating rolls to said receiving roll will draw said carriages towards each other and towards-said receiving roll to maintain said rolls in peripheral contact with the material substangtially constantly supportedrby said several r0 3. A transferring apparatus including a base, track portions forming a part of said base, carriages mounted upon said track portions, material manipulating rolls upon one of said carriages, a support fixed with respect to said base, a receiving roll and a delivery roll, one ofsaid rolls being disposed upon the second of said carriages and the other of the same being mounted by said fixed support, whereby upon said receiving roll being driven, said carriages will be drawn towards each other and towards the fixed support.
