I REINFORCED CORRUGATED PAPER.

naoreoa Specification of Letters Patent. Patented Apr. 22, 11919 Application filed December 2, 1918. Serial No. 264,881.

To all whom it may concern:

Be it known that I, HERMAN RINGEL, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Reinforced Corrugated Paper, such as-will enable others skilled in the art towhich it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, forming a part of this specification.

This invention relates to new and improved reinforced corrugated paper, and has for its object to provide a corrugated paper that shall be water proof, stretchable, as well as flexible in practically all directions, and which shall be further reinforced so asto adapt itself for use as a protective cover, wrapper or containant.

The object of my invention is to .unite, by means of a suitable Water proofing cement, two sheets of paper having incorporated therebetween a reinforcing filling as, for instance, some loosely woven fabric, like cheese cloth or any other equivalent thereof, thereby rendering the united sheets impervious to-water, moisture or weather conditions; and to further crinkle or crape the said water proofed sheets transversely thereby imparting thereto a transverse stretch of approximately ten per cent., and thereafter crinkling the same longitudinally in order to impart a longitudinal stretch of approxi mately thirty-three and one-third per cent. to the sheet.

Paper embodying my invention possesses the maximum degree of strength and stretchability and maintains its moisture proof, protecting and cushioning functions throu ghout the period of use.

In the drawings forming a part of this Figure 1 is a plan view of a piece of my improved reinforced paper, one corner thereof, being separated to show the sheet of cheese cloth or other equivalent thereof, and the water proofing material employed to unite the sheets together.

Fig. 2 represents an edge view thereof, and i Fig. 3 represents on an enlarged scale a transverse section thereof. Similar characters of reference refer to like parts throughout the specification and drawings. Referring to the present embodiment of my invention as illustrated in the drawings, my improved paper is preferably made from two sheets of paper 1 and 2, and a sheet of cheese cloth 3, or any other equivalent thereof, united together by means of a suitable water proofing cement 4, in any well known manner common in the art. After the sheets have been so united, which results in a single sheet, the same is passed through a craping machine and craped transversely as indicated at 5, thereby imparting to the sheet a longitudinal expansion of approximately thirty-three and one-third per cent. After the paper has been craped as above described it is passed through a suitable machine and provided with a plurality of longitudinal corrugations 6, which are preferably of such convenient form and size as to impart to said sheet a transverse expansion of approximately ten per cent. or more. It will be understood that the article of manufacture made in accordance with my invention, is suitable for a variety of purposes, as it has all the qualities of the paper from which it is made, together with the qualities of the cheese cloth, or any other equivalent material thereof, to which the paper is connected. It will now be obvious that any pull exerted longitudinally or transversely upon the paper will cause the crapes or corrugations to flatten and draw apart thereby permitting the paper to stretch in practically all directions. I have also found it desirable to treat one side of the finished article of manufacture as, for instance, the surface of the top sheet of paper, with a water proofing solution, so as to produce a water proof surface. All of these features are highly desirable in a paper which is to be used for baling or wrapping purposes, where the bales, for instance, are subjected to extremely rough and careless handling, and to variable weather conditions.

Experience has demonstrated that the organization above described is a highly efficient one, and while I haveshown the preferred embodiment of my present invention, ll do not wish to be limited to the exact details of construction shown and described, as obvious modifications thereof, not involving the exercise of invention, may be made by any skilled mechanic, and such deare of longitudinal and transverse expansion, comprising two sheets of paper and cheese 1 cloth interposed between said sheets of paper united together and rendered impervious to Water, said paper being craped transversely and corrugated longitudinally.

This specification signed and witnessed 2 this 21st day of November, 1918.
