Each of zhe rotetlve @uiting elements em# braces a piurality ef ciisis 'imving hubs up ei' the disks 'ae so'um'anged that the peripherai emacfee ei the isks 30 of' H18' wheei ci* puiiey 2 i@ receive a ciiiing beit 100 33. The i'oating euiing elements thus made 1 10 'cutting element at one side of the'path of the 34 between two disks of the opposite cutting element so that opposite cutting edges 33 of the opposite disks'y overlap each other in shearing relation, as most clearly indicated in Figs. 5 and 6; and it is between these coacting shearing edges that the web material is cut into strips or ribbons.

ln order to reliably feed the material between and present it to said shearing edges and to support thematerial While it is being cut, the spaces between adjacent disks 30 of each cutting element is provided with a friction element, herein shown as having the form of rubber or other yielding rings 35 which lie closely adjacent to the cutting edges 33. These rings 35 are shown as spaced apart and are made separately from, and are supported by, wider rings 36 of yielding material, as rubber, which fill the spaces between adjacent disks. One of each two adjacent disks may be undercut, as shown in Fig. 4, to reliably hold the rings 36 in place. Gbviously, however, the rings 35 and 36 may be made integral. The said elements serve to laterally' support the sheet material so as to' avoid loosening'e or sagging thereof and, therefore, holds the material reliably to the cutting edges. By reason of the offset relation of the cutting edges of the rotary cutting elements, the peripheral faces 32, 32,

.at the lateral edges of which are formed thel cutting edges, are presented in apposition to and bear against the peripheralfaces of the yielding feedsrings 35as most clearly shown in Fie'. 5. The said yielding feed rings 35 are siibstantially flush with the circular peripheral faces 32 of the cutting elements and are4 immediately adjacentto or in contact with the disks at their cutting or shearing edges, so that when the cutting edges of the:

disks overlap in shearing relation, the feed rings are slightly compressed by the disks,v

to thereby afford a positive feed o f the web material between `the rotative cutting elements. The strips which are thus cut from lthe webs 19 are wound upon reels 41, A41

located in sets on the opposite sides of the cutting line of the cutting elements 21,- Each set of said reels is fixed to a shaft 43 and said shafts are rotatively mounted intheY lower ends of swinging arms 44, 44 which latter are swingingly supported at theirupper ends on horizontal. shafts 45, 45 that? extend transi ersely between and are supported on brackets 46, 46 that extend divergently from and are supported in any suitable manner on the frame members 13. The said arms 44 and the shafts 43 constitute framesV t0 carry the strip receiving reels.' The said shafts 45 'are rotated fromthe shafts 23, 24,

before -referred to, through the medium of belts 47,47 which are trained about pulleys 48, 48 on said shafts 23', 24 and other pulle s 49, 49 on the shafts 45. The reels on w ich the cut strips are rolled are rotated from the pulleys 49, 49 through the medium of belts 5U, 50 trained about the latter pulleys and other pulleys 52, 52 on the reel shafts 43, 43. yEhe arms 44, 44 which thus carryI the reels are free to swing at their lower ends toward and away from the cut-I ting elements and the construction enables said arms and the parts carried thereby to thus move toward and away from said cutting elements without interfering withA the driving connections between said reels and the shafts 23, 24. The said reels, or the strip rolls wound thereon, are normallyprcssed toward the cutting elements so that the strips are wound directly upon the reelsA as they are delivered from ,the cutting elements so as to thereby wind the strips into compact rolls. As herein shown, the reels are pressed to ward the cutting elements by means of the weights 55, 55 which are suspended on the lower ende ofcables 56, 56 that are trained between their ends about directing pulleys 57, 57 and are attached at their upper ends to arms 58,58 which are attached in any suitable manner to the swinging reel carryingfrarnes. Thus it will be Iseen that the reels are normally held pressed against the adjacent sides of the cutting elements 21, 22 so that the strips cut by said elements are delivered directly from the cutting'elements to the reels; and by reason of the pressure exerted by the weights 55, 55 or equivalent pressure, the stri is are maintained in proper tension to Wind t lem compactly on the reels and are pressed or ironed by the pressure of the reels or rolls thereon against the rotative cutting elements. In order that the reels, when thestrips are first wound there on may closely approach thel cutting elements, the side plates or members 13 may be cut away, as shown at 60, to permit the shal'fts "of `the reels)A to enter therein and the reels to press agains the rotative cutting elements.

In order that the strips may be directed accurately to the reels, and in order to hold the turns of the roll laterally inplace onV the rccl,'l provide a series of guide fingers whichV are attached to, the machine, as

`herein shown, by being fixed to bars 66 that are bolted or otherwise attached to the bed plate 12; and said fingers extend outwardly from their points of attachment with their free ends overlapping the reels or rolls of strip thereon, as most clearly shown in Figs.

2 and 3. ,The saidvguide fingers are made ofv flatstrips of metal and bear iatwiseA against thc sides of the reels or rolls of strips wound thereon with a slight pressure and thereby maintain the margins of the strips Hush with cach,l other. so that thesides of the rolls produced are smooth. i
