3 Claims.

The invention relates to a cellulose hair pad for permanent waving. v

In Croquignole type of permanent waving the Y practice is to use a pad or jacket constructed to 5 provide an absorbent material to hold the solution or waving fluid so that the same may be placed in contact with the hair after being wound on a curling rod and the pad or jacket is provided with a metal foil or other protective material to l hold the steam or vapor, resulting from the application of heat, in contact with the hair and prevent it from escaping into the air. The customary method of constructing the pad or jacket is to attach the absorbent material, usually flannel l or felt, to the protective material, usually metal protective and steam and vapor retaining material is attached vto the absorbent material over substantially the entire surface by pressure mounting or by embossing and by the use of a moisture resistant substantially water proof glue or adhesive either spread evenly or in the form of a number of narrow lines or strips or streams of adhesive thereby eliminating the costly method of sewing or stapling the protective and absorbent materials together and at the same time permitting the use of absorbent cellulose which has little tensile strength especially whenwet with a hair treating solution but which is otherwise satisfactory and desirable.

With these and other objects in View, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended, it being understood that Various changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

(Cl. 13B- 362) Fig. 4 is a detail sectionall View on the line 4--4 of Fig. 3.

Fig. 5 is an enlarged detail plan view of a portion of one of the cellulose sheetsl Fig. 6 is an enlarged plan View of the pad with one of the cellulose sheets partially rolled back and other portions of the pad broken away to illustrate. the metal foil, the inner backing sheet of paper and the adhesive.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention the pad I which is designed for permanent hair waving-comprises in its construction a plurality of bleached porous sheets 2 of cellulose forming an absorbent wadding adapted to hold a hair treating fluid so that the same may be placed in contact with the hair 3 after the latter has been Wound on a curling rod 4 in the customary manner. The absorbent cellulose wadding may consist of any desired number of sheets of cellulose but tenhas been found ample. The sheets of cellulose forming the absorbent wadding are subjected to pressure or embossed preferably at intervals along parallel lines 2 shown at 5 to form interfitting protuberances and depressions which serve sufliciently to hold the sheets of cellulose together. The. uffy cellulose is pressed down to a relatively thin depth by the parallel longitudinal lines of embossing without compressing the entire surface of the cellulose sheets thereby forming an absorbent pad adapted to readily hold the required amount of any iluid or chemical solution for treating the hair.

The plurality of layers of cellulose fibers are held together by actually being intermingled at the embossing lines, one layer being forced into intimate contact and'intermingled slightly with another layer at the parallel lines of pressure. This intermingling and intimate contact and interlocking action of the bers of the layers are sufficient to hold the layers or laminations of cellulose ber together and form the absorbent pad.

An inner backing sheet B of paper preferably 20 pound full bleached sulphite machine glazed bond is applied to the absorbent wadding but any other paper or other suitable flexible material may be employed if desired. The inner backing sheet is secured to the cellulose wadding substantially throughout the entire surface of one of its faces'` by any suitable means of adhesion such as embossing, but preferably by a moisture resistant substantially water proof glue or adhesive 9 which may be of any desired composition and which may be spread evenly over the surface of the inner backing sheet or be in the form of a number of narrow lines or strips or streams of adhesive. The adhesive and the embossing securesy the cellulose wadding to the inner backing sheet sufficiently to enable sheets or layers of porous cellulose to be employed and while the thinl porous cellulose sheets or layers have little tensile strength kespecially when wet with a hair treating iluid they have been found highly satisfactory and desirableV from the point of their absorbent capacity as well as cheapness. The embossing or formation by pressure of the protuberances and depressions in the cellulose sheets may of course be of any other formation than that shown in the drawing but by arranging the embossing in parallel lines as shown the cellulose sheets or layers are connected with one another substantially throughout their entire surface.

An outer protective backing 1 consisting of a sheet of steam and vapor retaining metal foil is secured substantially throughout the entire surface of its inner face to the inner backing sheet 6 by any suitable means of adhesion such as embossing, and preferably by moisture resistant substantially water proong glue or adhesive lil which may be evenly spread over the entire contiguous surfaces of the inner and outer backing sheets or be arranged in lines or streams as heretofore explained for securing the inner backing sheet to the absorbent Wadding. Any suitable metal foil may be employed but it is preferable to use embossed aluminum metal foil .00065 inch thick. The thickness of the foil may of course be varied.

After the hair 3 is curled or wrapped around the rod 4 the pad is placed around the hairV as clearly illustrated in Fig. 2 of the drawing and it is held in proper position by'an electric heating element 8 which may be of any'desired construction. The cellulose hair waving pad may be employed in any of the well known methods of waving or curling hair where heat is used for permanently fixing Yor setting the hair and as these methods are well known detailed eX- planation of the same is unnecessary. While it is only necessary to emboss the fluffy porous sheets or layers of cellulose the entire pad may be embossed at intervals if desired and the inner backing sheet of paper may or may not be used.

What is claimed isz- 1. A pad for permanent hair waving comprising a plurality of porous sheets of cellulose compressed at spaced points to a relatively thin depth without compressing the entire surface of the sheets to form an absorbent wadding adapted to hold a hair treating uicl, and a protective backing including a metal foil secured by a water resistant adhesive to the absorbent wadding and coeXtensive therewith.

2. A pad for permanent hair waving comprising a plurality of porous sheets of cellulose compressed at spaced points to a relatively thin depth without compressing the entire surface of the sheets to form an absorbent wadding adapted to hold a hair treating fluid, an inner backing sheet of glazed paper secured by a water resistant adhesive to the absorbent wadding, and an outer backing consisting of a sheet of metal foil secured by an adhesive to the inner backing sheet and coeXtensive therewith.

3. A pad for permanent hair waving comprising a plurality of porous sheets of cellulose compressed at intervals along broken substantially parallel lines to a relatively thin depth without compressing the entire surface of the sheets to form, an absorbent pad, aninner backing sheet of paper fitted against the absorbent wadding and coextensive therewith and an outer steam and 1 vapor retaining sheet of metal foil arranged against the outer face of the inner backingr sheet and coextensve therewith, and a water resistant adhesive securing the wadding and the metal foil .to the inner backing sheet and disposed over.

approximatelyvthe entire surface of both faces of the inner baoldng sheet.
