fait? i6 are journaled ina frame 21 forming part of the main frame of the machine. The shafts 19 and 452,0 support the feed rollers Q2 and 23, each of which latter is pro vided with la male and female member 24 .and 25, these members extending the full length of the rollers, and being adapted to crease the paper as itis passed between these rollers. The members 24, 25 are so located that the paper passing betweenl the rollers will be creased so as to divide the' napkin lengths into three equal portions.

Mounted on the shaft' 9 between the large gear 8 and the small gear 14 is a s rocket wheel QG which drives a. chain 27, he latif" ,support is shown as comprising a bar 34 .having dropped end portions 35 of U-shape and upwardly curved side members or arms 36, each of which side members has a. slot .36 at its free end to receive a roller' 37.

These rollers are mounted on stub shafts 38 projecting laterally from the frame of the machine and which form a support for the inner ends of the frame of the blade carrying member and permit a rocking inovement of the frame as it is reciprocated through the connection with the crank shaft 29. This construction produces an undulating movement of the blade 30.

The sprocket chain 27 after passing 'around the sprocket wheel 28 extends to the opposite side of the machine and engages a sprocket. Wheel 41 on a stub shaft 42 suit ably mounted on the standard B, and is adapted to drive a spurJ gear 43 keyed to the shaft 42. Gear 43 is in mesh with a second spur gear 43 on a crank shaft 44 which is similar in construction to the shaft 29. This shaft 44 forms the support for one end of a support 44 'for a. second folding blade 45 which is complementary tothe member The support for this blade includes connecting rods 45 clamped to cranked portions of the shaft 44 and a bar 45 to whichthe inner ends of the rods 45 are connected. Side arms 46 extend forwardly from the bar 45" 'and terminate in slotted endswhich are adapted. to receive supporting rollers 39 mounted-v upon laterally extending stub shafts 40 secured to the freine. The support 44 likev the support 33 is adapted to rock uponits supporting shafts 40. Its construction is such that it can be manipulated without in. an y interfering with its complementary support 33, the sido arms 46 of the support 44 lying within the piane of the arms 36;

which are i throw and is adapt-ed to take up the slack of the last cut or severed end of the napkin, thus forcibly' freeing the tail end of the napkin from guiding tapes as the advancin edge of the napkin is caught between fee ing rollers 48 and 49. These `rollers 48 and 49 are driven by the sprocket chain 27", en-

gaging a sprocket 50 on the shaft of the roller 48, the roller 49 being driven by the gears 51 and 52. The speed at which these feed rollers travel is less than the speed of the rollers 22, 23 so that a second napkin will be speeded up in its feed toward the hopper to overtake the tail end of the advancingnapkin and be interfolded therewith. 53, 54, designate coperating lfeeding tapes which direct the severed portion of the paper to the rollers 48 and 49.

.The operation of the machine when adapted to fold paper napkins is as follows:

A roll 59 of crepe paper is sup orted upon a shaft 60 suitably mounted. in tlie frame of the machine and so arranged iii brackets 61 and 62 as to permit' a lateral shifting for centering by means of a hand screw 63. The web of paper is carried up over a roller bar 64 suitably supported in brackets 65-66 on :i :,-uperposed frame 67 and thence down over a folding horn 68' which effects the initial folding of the paper longitudinally of its length, the paper being effectively creased in its passage between rollers 57 which are positivelyfdriven by sprocket chain 27 which engages the sprocket 58 on the shaft of the left handy roller, motion being imparted to the complementary roller by gears 55 -56. The web of'paper which is now folded longitudinally of its length is fed between roll-k ers 22-23, the series of male and female members 24 and 25 of which give toi the paper spaced transverse creases first to one side then to the other. The paper so creased then passes the disks supporting the cutting blade i3 and is severed in appropriate lengths by the blade 13 A(zo-acting vwith the cutting member 13 the severed sheets passing on to the feeding tapes 53-54 which direct it into the bite .of the 'rollers As the advancing edge, of the napkin is gripped by these rollers the blade-arm 47 begins its initial movement forcing` the tail end of the napkin from engagement with .the feedingr `tapes.l Inasniuch as the speed ofthe rollers 4ta-49 is less than the speed of the rollers Qlf, the advancin napkin will reach t e' lbite of the rollers edge of a following 48449 at. the, moment, thepreceding napkin has been fed therebetween about 'tivo-thirdi-;
