W,LI-Mvm ATTORNEY Dec. 5, 1967 Filed Nov. 20, 1964 United States Patent 3,356,092 MULTI-PLY PADS 0R PAD FILLERS Curt G. Joa, Ocean Ridge, Fla. (Box 1121, Boynton Beach, Fla. 33435) Filed Nov. 20, 1964, Ser. No. 412,671 9 Claims. (Cl. 128-287) This invention relates to multi-ply pads or pad fillers used in sanitary napkins, hospital pads, diapers and the like.

Cross reference is made to my copending applications Ser. No. 184,105, filed Apr. 2, 1962, now U.S. Patent No. 3,322,589, and Ser. No. 296,208 filed July 19 1963, now U.S. Patent No. 3,291,131 which show multi-ply pads. The pad or pad filler and the method of the present 1nvention embody improvements over those disclosed in my prior applications aforesaid in the following respects:

(1) Each of the mat or batt plies of the pads or pad fillers of the present invention has an individual inner wrapper which is applied to ribbon strips of mat material disposed in laterally adjacent relation before these strips are folded into superposed relationship. Accordingly, when the superposed strips are cut ofi into discrete pad size units, the ends of each ply in the pad or pad filler are sealed with such inner wrapper.

(2) The pads or pad fillers are fabricated according to a novel method in which a plurality of ribbon strips of mat or batt material are fed in laterally spaced side-byside relation, wrapper sheet material is fed over the entire width of the ribbon strips at the top and bottom faces thereof, the sheet material is sealed together across the lateral spacing between adjacent mat ribbon strips to form bendable links laterally between the strips and the strips are then folded laterally about said links into superposed relationship.

. (3) By reason of the method aforesaid, great flexibility in the number of plies in the ultimate pad or filler product is achieved. The number of plies can be varied, for example, by varying the number of ribbon strips which are fed in side-by-side relationship.

(4) A contoured shape for the ends of the ultimate pad product is readily achieved by varying the widths and thickness of certain of the mat ribbons, for example, the two outermost ribbons. When these are folded into superposed relation with respect to the innermost ribbons and discrete portions cut therefrom, the ends of the pads thus produced are tapered or contoured.

(5) The method aforesaid facilitates addition of a moistureproof barrier ply into the pad. This ply is fed concurrently with fabrication of the pad and is desirably laid over one only of the mat ribbons and is desirably heat sealed to the wrapper plies in the spaces between adjacent ribbons.

Other objects, features and advantages of the present invention will appear from the following disclosure in which:

FIGURE 1 is a diagrammatic plan view showing some of the apparatus for fabricating multi-ply pads embodying the present invention.

FIGURE 2 is a side elevation of the diagrammatically shown apparatus of FIGURE 1.

FIGURE 9 is a perspective view of a filler for the napkin of FIGURE 8.

Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. The scope of the invention is defined in the claims appended hereto.

In accordance with the present invention, laterally adjacent spaced apart ribbon strips 10, 11, 12 and 13 of mat or batt material are fed from conveyor belt 14 onto conveyor belt 15. The mat or batt strips 10-13 inclusive may be formed on apparatus as shown in my U.S. Patent 3,086,253. A bottom tissue sheet 16 from parent roll 17 is fed over conveyor belt 15 to underlie the strips 10-13. A relatively narrow barrier strip 18 of moistureproof material such as polyethylene or like plastic filler is fed from a parent roll 19 around guide roller 20 and over one of the mat strips, for example strip 12, as shown in FIGURE 1.

Thereafter a top tissue sheet 22 is fed from a parent roll 23 around guide roller 21 to overlie all of the mat strips 10-13 and strip 18. Accordingly, the mat ribbon strips are covered top and bottom by the wrapper tissue sheets 16, 22, and one of the mat strips 12 is also covered at its top surface with a barrier strip 18.

The wrapping sheet materials in the spaces between adjacent mat strips 10-13 and at the extreme lateral margins of the assembly of strips are cold crimped together by the opposed upper and lower crimping wheels 24, 25. The lateral margins of the barrier strip 18 are heat sealed to the wrapping sheet material laterally adjacent strip 12 by heat seal wheels 26-heated from heating element drums 27, the heating elements therewithin being energized electrically from a source 28.

Reference character 29 is applied to the seals formed by the cold crimping wheels 24, 25, and reference character 30 is applied to the heat seals formed by the heat seal wheels 26. This process results in the formation of llagncllgble link strips 32, 33, 34 between the ribbon strips At this stage in the fabrication of the pad, the condition sp wn in FIGURE 4 exists. Each mat strip 104: is individually contained within tissue wrappers 16, 22, these being cold crimped at 29 in the bendable link strips 32, 33, 34 between adjacentpads' 10-13. Pad'sttip 12 is additionally provided with a covering of moistureproof materlal 18 heat sealed to bendable link strips 33, 34 at 30.

A pair of plows or folding boards 31 now fold the outermost ribbon strips 10, 13 on the bendable links 32, 33, 34 to superpose mat strip 10 on mat strip 11 and mat strip 13 on mat strip 12, as shown in FIGURE 5. Another plow 36 then folds the mat strips about the bendable link 33 to dispose the respective mat plies 10-13 in a superposed stack. The belts 35 carry the stacked ribbons to the apparatus shown in FIGURE 3.

Accordingly, the respective mats which are superposed one on the other are sealed individually within the wrap per sheets 16, 22 and the bendable links 32, 33, 34 between successive adjacent mats are staggered at opposite sides of the continuous strip of superposed mats, as shown in FIGURE 6. The barrier ply 18 is offset toward one side of the composite stack of mat strips.

The composite strip shown in FIGURE 6 is now further processed as shown in FIGURE 3 in which it is overwrapped by a wrapper sheet of crepe wadding 37, the margins'of-the crepe wadding being overlapped'by a cover ply of wadding 38 which spans the space between said margins, as shown in FIGURE 7. Seams 4-0 between wadding. strips;37, 38 are formed by crimping wheels 39. This condition is shown in FIGURE 7. Not only are the-mat p1ies.10-13= provided with inner wrappers 16, 22, but the composite stack is provided with outer wrapper 37, 38; The inner wrappers 16, 22 are made of tissue which. is only aboutone half as costly as the wadding 37, 38 and functions to contain the fluff material ofthe mat strips 1043 in. place within. the outer wadding wrapper 37, 38. Accordingly, the fluff material cannot spill out of the confinesof the inner wrappers.

As is also diagrammatically shown in FIGURE 3, individual discrete pads or pad fillers 43 may then be cut laterally from the-composite pad strip shown in FIGURE 7, thus to form. pad. fillers for further use such as in sanitary napkins. When cut at an angle, as shown in FIGURE 3, these pads or pad fillers have converging sides. Such a filler is shown in FIGURE 9. The ends of the fluff filler are closed or sealed: by the wrapper sheets 11, 22, 37 and the sidesof the fluff are exposed. If desired, however, the cuts: may be perpendicularto the margins of the pad strip to. form pads with parallel sides. Where the; discrete pads 43 are to be incorporated in a sanitary napkin, for example, they are encased. in a wrapper 44' shownin- FIGURE. 8 to constitute a napkin 45.

The offsetting of, the barrier strip 18 toward one side of the compositepad, as shown. in FIGURES 6, and 7, gives the pad selective absorption capacity depending upon which side of the, pad is worn toward'the body, for example, in a, sanitary napkin, diaper or hospital pad. Ordinarily, the. barrier strip 18 will be offset away from that side. of the pad which is worn next to the body to provide; the greatest; absorption. However, if the pad is inverted when in use, therev will still. be ample absorption in that; portion of the pad between its face toward whiohthe, barrier strip. 18 is offset and, the barrier strip. The barrier; strip: prevents strike through.

By making the; laterally outermost ribbon strips 10,

1 3, narrower thanthe innermost; ribbon: strips 11, 12, the

ends; of the: final product as shown in FIGURE 8 are aper d. or. ontoured.

Fromv the. iqmgoing. it. is clear that the method of fabricating the pad: and. the pad product resulting therefrom; asihieye the advantages first set outin this specifica. tion, The resultant product is alternatively characterized as. a, pad or pad filler because it is capable of use as shown in its condition in-FIGURE7, before further wrap-. ping, or it may be used as a filler for the wrapper 44 shown in FIGURE 8. The dimensions, of the pad will vary according to its intendeduse Those illustrated inthe instantdrawings relate specifipally to an end use; in a ypk T e mat plies, etc. w uld e made much.
