-Fig.:6 represents papernapkins made according to the present invention; and

Figs. 7 and 8 show different types of rolls for wetting the paper.

As illustratedin the drawings crepe paper C is fed from a roll 1 having" a surfa'celunwinding belt 2, over a roll 3, thence under a'la-rger roll 4 where the paper is wet along both'atransverse and longitudinal lines for the purpose o ftearing the paper along these lines into napkins or other units ataflater stage in the apparatus, thence over a large V ylnterconnectedby rods 21 at-the1r periphery skeleton roll 5,:thence between the lower roll .6 and upper rolls 7 and g8 where-the paper -.is torn both transversely and longitudinally into units U,.which are fedbet'ween upper and=lower sets of

guidebelts

9 and 10 around the drying drum I11 an'dithence to anysuitable receiver or conveyor, suchas illustrated by the=belt conveyor 12. A part or all. of the rollers of drums, over which the paper passes, may be driven by any-suitable driving means,it .being understood-that driven rollers as spaced locations along the path of the paper should-be synchronized asbygeauving the rolls together inwellknown manner. While passing under roll 4 the paperis wetalpng transverse and longitudinal lines by means of one or more rolls such as shown still? and 14;, these rollshaving peripheral ridges which'pick up the moisture from 113115 155 and 16 respectively, dipping in pans 17 and 18, andtransmitting the'liquid 1:126. Serial mama.

to transverse and longitudinal lines on the paper where the ridges contact with the paper. One of the roll-s13 and 14 may have circumferential ridges, such as shown at 19 in Fig. '7, to wetthe paper along longitudinal lines and the other of these two rolls may have one or more longitudinal ridges,

suchas shown at 20 in Fig. 7, 'for wetting the .paper along transverse lines; or one of

therolls

13 and 14 may have both circumferential and longitudinal ridges such as illustrated in Figi 7, in which case one oi the two rolls may be dispensed with.

' slheliquid in'pans' 17 and '18 maybe colored to color the edges of the torn paper articles andlby employing two pans and associated rollers two colors may be applied to .the edges or the articles. "In this'case each roll maybe provided withboth circumferential and longitudinal ridges 19 and 20 which are discontinuous as illustrated. in '8, in which case the tWo rolls '13 and 14ers so synchronizedthat, one roll-wets-the paper in the spaces between the places where theother roll wets the paper, so that the .two colors alternate along the edges of the article both transversely and longitudinally of the sheet. Obviously other types or printing and coloring maybe employed, including the printing oi monogram's or designs inside the margins of the paper articles.

The skeleton roll 5 comprises end disks so that the paper when passing over this roll contacts wit-lithe r'oll only along narrow lines so as not to spread the liquid in the paper. If desired the rods 21 may be grooved on the outside at the places where the :longitudinallines of wetting occur so 1 betweenthe transverse lines of wetting preterabl y. being equal to the distance between the rods 21.

As shown in the drawings the apparatus is'inten'ded to divide the paper C int o three equal widths and to trim o'fi the margins. Aiter'the paper passes over the skeleton drum 5 the margins '22 of the paper are fed between'tw'o pairs of rolls respectively, one

pair being shown at 23 in Fig. 1. The ro ls 23 are driven in synchronism with the drum 5 so that the margins are torn off at the roll 24 by the pull of the rolls 23, the main portion of the paper continuing through the mechanism which divides the sheet longitudinally and transversely as will now be described.

The roll 6 has two longitudinal recesses in its periphery and two relatively wide circumferential recesses 26 (Figs. 1 and 3) to accommodate the

tearing blades

27 and 28 mounted on a common rotor. The blades 27 are in the form of disks extending into the groove 26, it being understood that the grooves and disks are spaced transversely of the sheet to correspond with the spacing of the

ridges l9'on rolls

13 and 14 which wet the paper before it reaches the tearing mechanism. However, as indicated in Figs. 3 and 4, the longitudinal linesfZS along which the paper is wet preferablypass slightly to one side of the tearing disks 2? so that the disks do not contact with the moist lines: consequently when using coloring matter it does not contact with the disks and therefore does not smear when the paper is torn. Inasmuch as the disks 27 extend into the grooves 26 across the plane of thepaper the paper is torn along the longitudinal moist lines 28 by the disk 27. The paper is torn along the transverse lines of wetting by the blades 28 passing into the grooves 25 as illustrated in Fig. 5, it being understood that the circumferential distance between the grooves 25 is approximately equal to the distance between the transverse lines of wetting on the paper. However. the transverse lines of wetting 29 (Fig. 3) preferably come slightly in the rear of the line of contact between the paper and the blade 28 so that the blade does not contact with the moist line. The blade 28 is divided into sections to accommodate the disks 27 as shown in Fig. 4. The blade 28 is also recessed as shown at 30 so as not to contact with the longitudinal lines along which the paper is wet. The blade 28 is also provided with recesses 31 to accommodate the belts hereinafter described. The rolls 7 and 8 are provided with longitudinal grooves 32 and ClICUHlfGT- ential grooves to avoid contact with that part of the paper which is wet.

After the paper is torn longitudinally and transversely into small units U as above described it passes between the

belts

9 and 10 thence over the heating drum 11, which is heated in any suitable manner, and thence to the conveyor 12, the

belts

9 and 10 and the conveyor belts 12 traveling in the direction indicated by the arrows.

In order to insure uniform feed of the paper articles between the

belts

9 and 10 after they are separated by the tearing mechanism as above described, blades 33 are mounted on the shaft 34 to extend into narrow grooves 35 in the roll 6 as illustrated in Figs. 2 and At each end of the shaft 34 a single blade is mounted on a. hub 36 and between each pair of belts two blades are mounted on a single hub 37, 37, 37 (Fig. 3). In the spaces between these hubs belt pulleys 38 are mounted to rotate on the shaft 34:.

As shown in Fig. f the roll 7 is provided with peripheral grooves 39 the depth of which is approximately equal to the thickness of the belts 9, whereby the outer surfaces of the belts in these grooves are ap proximately flush with the periphery of the rolls 7 so that the paper C is not deformed by the belts 9 as the paper passes under the roll 7.

From the foregoing it will be evident that paper may be divided longitudinally and transversely into units of any desired size, that the operation is continuous and automatic, that the edges of the units maybe colored with one or more colors, and that after the paper is moist by the

rolls

13 and 14 the moistened lines do not contact with any part of the apparatus until the paper reach the

belts

9 and 10. Inasmuch as these belts are continuously dried by the dryer 11 they do not tend to smear thecoloring matter.

As shown in Fig. 6 the crepe paper napkin to, which is illustratii e of the many articles adapted to be made according to this invention, has its torn edges colored alternately with two colors ll and 42 confined substantially to the width of the margin of irregularities in the torn edges.
