' into tubes. The, invention is especially designed to work upon crinkled paper and it consists of the various features and their ar:

rangement and combination hereinafter pointed out. i

In the accompanying drawings forming part of this spe cification,- and in which like reference numerals designate corresponding parts,' the invention and itsva'rious features are shown in the preferred form.

In the drawings, 1

taken'on the T Fig. 6 is a sectional elevation taken on the 'line 6 6ofFig.5. VJ

Referring now to the particular structure showninthe. drawings, 1 is the mainframe of'the machine inwhich is mounted a shaft 2 carrying theroll 3. This roll is suitably driven astfrom the pulleys 4. Fixed on shaft 2 are gear wheels5 and 6 which mesh with and drive gear "wheels 7 and 8. fixed on shaft 9 mounted in the main frame. The roll lO is fixed on shaft Surrounding the shaft 7 9 at its ends are two' sleeves 11 and 12' which -are"fix,ed 50 against rotation I the boxes 13 and 14 surrounding the shaft. -,On these sleeves 11 and 12 are two stationary cams 15 and ,16. 1:7 is a rock shaft mounted in ther'oll and carrying a series of arms 18 provided. with pins 19 at their outer ends. The ends of the rock shaft 17 are providedwith fixed arms i 20 and 21having rollers "at their outer ends which ride on the cams and 16.: i' A spring 22,' having one end secured to -a 11153 on the shaft and .the' other end secured to'the roll 10;

serves to keep the arms and 21 incont'ac t with their cams 15 and 16. -Fixed1radially in the periphery' o'f the roll 10 is a ,knifel23 gether with the knife 25, are arranged to re clprocate between pairs of guide brackets f 28 and 29 fixed on the opposite ends ofthe r0113. Radial movement is imparted to the knife'by cams 30 and 31 which engage the rollers 32 and 33 fixedon the blocks 26: and/27;

respectively, SpringsB L and '35 keep these rollers in contact with their cams: These springs are connected, at. one *end to the blocks and at their other ends, to sleeves 36 and 37 fixed in the boxes supporting-the shaft 2 of roll 3. v Cams 30 and 31 ar'e fixed on these stationary sleeves. Riveted tothe lower margin of the knife 25 is a bar 38 through which loosely pass the parallel with the knife a series of bolts 39 surrounded by springs40. and at their upper end] screwed into a bar ll lying close against the knife and whoseupper surface projects slightly above thesurface ofthe roll 3. The springs' 4O fit in recessesin the bars 38 and 41. 'These bars and the knife are located in a radial row cylindrical sections, each, of. whichis fixed 'Securelyon its shaft. 1 This arrangeg r ment saves material and. furthermoregi connection withi'froll 22, enables the arms 18 on rock shaft 17 to be mounted between the sections of that roll. One of the funci tions of these rolls 3 and 10' is to receive its reciprocating movebetween them and feed forward the web of paper 44 and, when such paper is crinkled, it is advantageous that at least one of these rolls be provided with teeth on its periphbe injured and the paper unduly stretched.

One of the rolls, as roll 3, may have a smooth 7 surface as shown. In the operation of the rolls '3 and 10 and their knives, when a predetermined length of the paper web is passed between the rolls and just before the knives 23 and 25 come into alignment,

bar 41, which projects slightly above the periphery of the roll 3, grips the paper between it and the cooperating bar 24ron roll 10, bar 41, owing to its spring mounting, yielding to the pressureput upon it by the bar 24. At substantially the same time, arms 20 and 21pass beyond the elevated portions of theircooperating cams 15 and 16 and the spring 22 rocks the shaft 17 so as to throw the pins 19 forward and outward through thepaper on a line just back ofthe knife23. At substantially the same time rollers 32. and 33 of knife 25 pass on to the elevated portions of their cams 30 and 31, thereby moving knife 25-outward so as to severithe paper in cooperation with knife 23. As the rolls 3 and 10 continue their movement, the knife rollers32 and 33 travel off of the elevated portions of their cams and knife 25 is retracted by its springs 34 and 35. At the same time the pins 19 carry the paper which they have engaged aroundthe roll22 and continue to thus engage the. paper until .the arms 20 and21.

have traveled slightly beyond three-quarters of a turn, when they rise upon the elevated portions of their cams and thereby retract the pins from engagement with the paper.

'As the rolls continue their movement, the knives repeat their action to cut offanother length of paper and the pins 39 repeat their action totengage a new length of paper just entering between the rolls. As each separate sheetlof paper is released from the pins 19, it passes off from the roll 10 in the' manner described in my pending application above referred to,

While the invention is shown in the drawings in what is believed to be its best form, it is to be noted that various changes in the form and arrangement of parts may be made without departing from the scope of the invention. p
