CBEPING PAPER.
' Application filed January 14, 1926. Serial No. 81,189.
This invention relates to a method of pro ducing creped paper embodying a layer of waterproofing material such, for instance, as asphalt. It finds particular application to the roduction of creped duplex paper comrising two paper layers cemented together y an intervening waterproofing layer.
The invention will be well understood by reference-to the following description of a preferred method of preparing a duplex paper in accordance therewith when taken in connection with the accompanying drawing diagrammatically illustrating the same.
Duplex paper for wrapping and packing purposes consistin of two sheets of substantial paper, suc for instance, as kraft paper, cemented together by a layer of asphalt, commonly the pitchy residue of petroleum distillation, applied a in melted form is well known. Such paper may be creped by the roll and doctor crping process essentially as described in the patent to Arkell, No. 790,021, granted May 16, 1905. For this purpose a completed duplex paper 5 has been saturated thoroughly in water, de-
posited on a crping roll and pressed into firm adherence thereto and then crowded back on itself by a doctor blade cooperating with the roll which at the same time stripped the aper from the roll in ci'ped or crinkled condition. In this process a very thorough saturation is necessary to penetrate the paper and prepare it for the crping operatlon. In articular it is necessary to em y a hot ath both to assist the saturation of the paper, since the sizing thereof resists the penetration of moisture, and also to soften the solid asphalt layer between which has a certain stifiness and unless heated in this manner will not conform properly to the crping roll or be sutficiently fluid to permit the crping operation to be efliciently efl'ected. In this saturation a part of the sizing of the paper is removed. V
In accordance with my invention I duplex and crepe paper as a continuous process. Water roofing material in a watery vehicle is app ied in fluid form to the paper which is immediately crped. Thus instead of coat- 05 a and as drawn from supply rolls and the paper with melted asphalt I may utilize an emulsion prepared by mixing thepassing down between a pair of horizontally arranged rolls 3 and5 inface to face relation. Suitable end walls 7 are placed near the ends of the rolls and define with the opposed cylindrical surfaces of the rolls a trough-like structure. The asphalt emulsion in the form of a thick fluid, almost a paste in consistency, may be delivered to this trough from a suitable container diagrammatically illustrated at 9 and is thus fed to the opposed faces of the webs a and 6 overlying the'sides of this trough. The spacing of the rolls 3 and 5 will accurately determine the amount of the emulsion which is thus introduced between the two layers of paper. Passing from the pair of rolls 3 and 5, the two webs a and b may then be passed through a air of squeeze rolls 10. These will cause t e two webs to cohere with considerable tenacity and will also assist in driving the water which forms the vehicle of the asphalt emulsion into the paper. An emulsion of this character is a mechanical mixture as distinguished from a solution and it seems probable that the paper blots out,
as it were, a certain amount of the moisture and that the pressure of the squeeze rolls may 5 ueeze some of the moisture out from the solid matter in a way which may be figuratively compared to the squeezing of water from a sponge. In any event the compound web passing from the squeeze rolls has considerable coherence and the paper is damp and in a good condition for crping.
The compound web may be moistened on the outside, as by means of a coating roll 11, to secure its proper adhesion to the crping roll and, if desired, this moistening may be effected by means of water containin size or dextrin or like material having ad esive roperties. The web is then led to the creping roll 13 against which it is firmly pressed by a squeezeroll 15 and is crowded back on itself while adhering to the creping roll by means of the doctor blade in well known 1 manner. The crped duplex web is then dried in any suitable manner as indicated by the diagrammatic showing of the drier 19 and may be 'rewound for use.
The asphalt emulsion may be prepared in any desired quantities and stored and diluted as necessary for use when desired. In the crping process as described no heat need be employed, an expensive and oppressive feature of those processes in which the asphalt for the crping operation.
is applied in a melted condition and in which hot water is required to saturate the duplex paper. The layer of emulsion carried in the compound web ab to the creping apparatus has at that time no stifi'ness and heat is not necessary' to prepare it- It Wlll be noted that the prolonged soaking of the paper in a saturating bath is done away with as moisture is introduced with the asphalt emulsion between the layers of the paper. When introduced in this manner it penetrates readily and may be distributed through the body of the paper in the manner described. Probably a lesser amount of water is required properly to prepare the paper for the crping operation but, certainly, the softening of the paper by the crping operation in a uniform manner is more readily and convenientlyeffected than in the case Where dry completed duplex paper is passed through a saturating bath. The crped product is distinguishable from the product prepared by the old method, having a more leathery and tough appearance and feeling.
I have described in detail one particular method by which my invention may be practiced. Obviously the. details described are not essential to the invention in its broader aspects but may be considerably varied without departing from the spirit of the invention.
What I claim as new and desire to secure by Letters Patent I shall express in the following claims:
1 A method of producing waterproofed creped paper which comprises applying waterproofing material in a watery vehicle to .the paper simultaneously to wet the same and to distribute the waterproofing matenalthereover, crping the moist paper and drying the same to expel the vehicle and to deposit the waterproofing "material.
2. A method of producing crped Waterproof duplex paper which comprises introducing between layers of paper waterproofing material in a water vehicle simultaneously to wet the paper and to distribute the Waterproofing material' thereover, creping the moist layers as one and drying the same to expel the vehicle and to deposit the waterproofing material.
3. A method of producing crped duplex paper which comprises duplexing two layers of paper with pitch suspended in a watery vehicle, crping the product while softened by such vehicle and drying the crped product.
4. A method of producing crped paper which comprises leading together two paper Webs, pouring an asphalt emulsion between them, pressing them together, leading the connected webs directly to a crping apparatus and drying the crped product.
5. A method of crping paper comprising applying to the paper a pitch emulsion both to provide a coating for the same and to soften it by the moisture of the vehicle, depositing the moist paperon a crping roll, crowding it back on itself while adhering to said roll and drying the resulting product.
'6. A method of crping paper comprising introducing a layer of emulsified pitch between two layers of paper, pressing together the layers to cause them to cohere and to assist the-wetting of the paper by said emulsion, causing the compound layer to adhere to a crping roll, crowding it back on itself while adherent thereto and drying the crped product. 4
In testimony whereof, I have signed my name tothis specification.
