Description
Patented Sept. 29, A1931 UNITED STATES PATENT OFFICE ANN'ING SMITH HAMMOND, OF LOS ANGE-LES, CALIFORNIA, ASSIGNOR 'JTOr VWIlSflIlilItN WAXED PAPER COMPANY, OF OAKLAND, CALIFORNIA wax Puna Application filed August 24. 1926. Serial No; 181,148.
Broadly this object is attained by utilizing' the advantages of different grades of wax without their disadvantages while more speciiically there is initially applied to the paper a wax having a relatively low melting point and then finally applied thereto a wax ha ving a relatively high melting point.
A further object is to provide an improved apparatus and method for making waxed paper as above described.
Further objects and advantages will be apparent from the following description of the accompanying drawing, which is a diagrammatic side elevation of the apparatus.
In the illustrative embodiment of the invention there is shown a receptacle 1, having compartments 2 and 3, separated by a suitable partition 4. Molten wax having a given melting point will be disposed in compartment 2, while molten wax of a higher melting point will be contained in compartment 3. The wax in each case, such as parain or a wax having similar qualities suitable for waxed paper of the self-sealing type wherein sealing of an article is accomplished by heat and pressure, is melted by suitable heating coils Whilethe temperature thereof is controlled by any suitable and usual temperature controlling mechanism. To wax a strip of paper there is provided a suitably journaled roll of raw paper stock 5 from which a strip S will pass beneath an adjustable contact idler 6, and over the top of an advance roller 7 suitably journaled upon the top of the receptacle 1 so that the lower portion of .the roller 7 will be immersed in the wax within compartment 2. The paper will continue and pass over an adjustable scraper 8, then be completely submerged in the wax of compartment 3 by passing beneath an adjustable submerging bar 9, the paper continuing on between a steel roller 10 and a rubber roller 11, suitably journaled in the framework 12 after which it is led to suitable cooling roll-4 ers for final treatment and disposition.
It is to be noted that the wax in compartment 2 having the lowest melting point is applied prefera ly to only one side of the paper strip whereas the wax having a higher melt- 1ng point is applied to both sides thereof.
The scraper 8 removes any excess wax from the strip prior to its immersion in the wax within compartment 3.
Bylthe method of first impregnating the rawv paper with wax of a low melting oint and then coating the paper with a h1gher melting point wax, I produce a waxed paper havingv an inner impregnated layer and an outer layer of wax, the outer one being a coating not readily affected by ordinary -atmospheric temperatures but yet having qualities which permit an efiicient seal to be made when heat and pressure are applied to the wax paper, this being the characteristic of a wax having a high melting point when used in combination with the inner layer of im- -pregnated wax having a lower melting point. On this account 'the wax will not soften which, if it did, would permit the paper to stick together or block in Vwarm weather. A further advantage obtained with such a coating isthat the waxed paper will slide readily over metallic or'wooden guide plates usually em loyed in machinery such as automatic brea wrapping machines, which may become quite warm.
If a waxed paper contains only a wax of high meltin point the same at ordinary temperatures w1ll be brittle, but I have found that this disadvantage can be overcome by rst applying the wax of lower melting point. The use of this wax not only overcomes any disadvantages of the higher meltin point wax, but has the further advantage because of its gumminess and tenacity at ordinary temperatures to supply a better sealing me dium. Waxed paper to be sealed is usually heated under pressure, and under such conditions there will be a certain amount of admixture of the two kinds of wax, this occurring mostly at the surface' of the aper at what might be called the joint o the two different waxes. As the gummy low melt- Cal p each grade of wax may be inde endently controlled. It will 'of course e understood that various modifications of such a machine could be vhad and that various auxil- .iary mechanisms that might be desired could be employed in connection with -a machine such as diagrammatically disclosed herein. Any suitable mechanical drive could be employed for driving the necessary rollers for feeding the paper strips, such not having been shown in view of the nature of the drawmg.
I claim 1. The method of making self-sealing waxed paper consisting in first applying to a strip of pa er wax having a given melting point and t en applying a wax having a higher meltin point.
2. The met od of making self-sealing waxed paper consisting in first applying to one side f a strip of paper a wax having a 8. A wax sheet of aper consistin of paper stock im regnated) with a low me ting point wax, an an outer coatin of wax on each side of the sheet, having a 'gher melting point. I

given melting point and then applying a sec.
ondcoat' of wax having a higher melting point.
3. The method of making self-sealing waxed paper consisting in first impregnating a strip of paper with Wax having a 10W melting point by applying said wax to said strip on only one side thereof, and then applging to both sides o said strip wax having a igher melting point.
4. The method of making waxed paper consisting in first applying to a paper strip a wax having a low melting point, then applying wax having a high melting point, and then applying mechanical pressure to opposite sides of the strips.
5. The method of forming waxed paper consisting in taking a piecel or' raw paper'` stock and impregnating the same with a 10W melting point wax, then scraping the strip and then applying a final coating of wax having a higher melting point. Y
6. A wax paper of the type adapted to be sealed when overlapping ortions thereof have heat and pressure applried thereto, consisting of paper stock having two coats'of wax of different melting points.
7. A self-sealing wax paper consisting of paper stock having an inner coating of Wax of a given melting point impregnated inthe paper stock, and an outer coating of wax of a higher melting point whereby when pressure and heat is applied to overlapping pory tions of the waxed paper the two coatings of wax have some admixture so that the low y f melting point wax may permit its gummy qualities to become effective in sealing.
