cnusnrrs 7 BEENFOBCED BUILDING PAPER.
Application filed November 26, 1936. Serial No. 498,267.
This invention relates to a novel form of reenforc'ed paper adapted for use as a building or wrapping paper and for other purposes.
Two types of reenforced paper are now on the market; in one of these types the paper is reenforced by such materials as wlre or unspun fibres of long staple that are no more elastic than the paper itself, and although these reenforcing elements are stronger than the paper, both give way or rupture simultaneously when subjected to a breaking strain; in the second type the paper is reeniorced by spun strands of cotton, linen, jute, etc. or by a woven fabric formed of spun fibres, and although such reenforcing materials are stronger than the paper, they are moreelastic due to the twists in the reentorcing yarn or twine, and as a result these twisted reenforcing elements will stretch under tension and permit the paper to rupture,
The present invention is directed to a third and new type or" reeni orced paper which is capable of stretching to a substantial degree without rupturing, and is formed by adhesively securing reenforcing elements in a straightened condition between sheets of paper that have previously been craped, crimped or crinkled, so that the paper may stretch under tension without rupturing. As a result of this new construction an elastic or stretchable reenforced paper is produced which is well adapted for various uses where this elastic condition is desirable to prevent the paper from rupturing.
The reenforcing material may be either spun or unspun fibres or a reenforcing sheet which is not readily ruptured, and very good results are secured through the employment or unspun fibres of long staple as the reenforcin elements. The reeniorcing material is pre erably secured between the sheets of paper by a waterproof adhesive such as tar or black asphaltum to render the paper moisture-proof,
stretchable, reenforced, waterproof paper constructed in accordance with the present invention may be subjected to a strain that is suflicient to breaksome of the reenforcing fibres without necessarily causing the 'craped or crinkled paper to rupture or lose its water-proof quality.
While the elastic reenforced paper of the present invention constitutes a cheap waterproof covering that may be well emplo ed as a wrapper for bales, bundles and pac ages, and in the construction of bags, where additional strength over ordinary paper and a certain amount of give is required to prevent the paper from rupturing, it is articularly well adapted for use as a bui which will not rupture or pull loose from its securing means under the contraction and expansion of the paper, due to weather changes.
In employing building paper heretofore, in building constructions, much diiiiculty has been experienced when the paper is exposed to the weather, due to the tendency of the paper to shrink under the action of the sun and rain, and pull loosefrom the nails or other means employed to fasten the paper in place. This shrinking action of the paper is particularly noticeable when a multiply building paperis used having a waterproof coating between the sheets of paper, since while the inner sheet dry by the coating material, it is acted upon by the repeated shrinking pull of the outer sheet of paper, without expanding with the outer sheet to relieve its tension.
These difficulties are overcome employment of the reeniorced paper of the present invention, as a building paper since the face of the multiply paper exposed to the weather may contract and expand freely without rupturing or imparting its shrinking action to the underlying reenforcing material or inner sheet of paper. In this manner the tendency of building paper to shrink and pull loose from its securing means under the action of the weather is entirely overcome.
The above and other features of the invention will be further understood from the following description when read in connection with the accompanying drawing, wherein Fi 1 is a perspect1ve view of a piece of multiply reenforced paper constructed in accordance with the present invention, the
through the SACH'USETTS, A CORPORATION 01 MASSA- i ding paper I of paper may be kept sheets of paper bein partly rolled back to show the reenforcing bres;
Fig. 2 is a perspective view showing the paper of 1 as secured to a supporting structure in icated in dotted lines; and
Fig. 3 is a sectional view of a modified form of the reenforced stretchable paper of the present invention.
In the embodiment-ofthe invention illustrated in Figs. 1 and 2 of the drawing, the multiply reenforced pa er consists of the two sheets of paper 10 an; 11, each of which is crimped, crinkled or given a crape construction throughout its area as shown. This is done to render the paper elastic or capable of stretching. In many cases the paper need be crimped or crinkled in only one direction to render it sufficiently elastic to secure the desired results, since if the crinkles or creases extend transversely of the aper, as shown in the drawing, the aper will e rendered elastic to a substantial egree in the direction of its length and will also be rendered elastic transversely to a slight degree. The paper, however, may be provided with crinkles or creases extending both longitudinally and transversely when it is desired to secure a pa or that is capable of stretching to a substantial degree both longitudinally and transversely.
While, as above stated, various reenforcin materials may be used between the sheets paper and 11 to impart the desired strength to the composite paper, excellent results are secured through the employment of relatively lon unipun fibres, such as sisal. The paper is t ere ore shown as reenforced by one set of straightened unspun fibres 12 extending longitu inally of the paper and another set'o straightened unspun fibres 13 extending transversely of the paper. It is not always essential however, to reenforce the paper both lon 'tudinaly and transversely.
he adhesive employed should serve to firml secure the reenforcing fibres and the two s eets of aper together so that the fibres will materia y increase the stren h of the pgper and while the adhesive emp oyed may non-waterproof, a waterproof adhesive such as black asphaltum is usually desirable to prevent the moisture that reaches one sheet of paper from penetrating through to the second sheet of paper or from decreasing the grippiii7glpction of the adhesive.
en multiply building pa r having the constructionemployed hereto ore is secured to a building in an unprotected condition, it is found that the multiply paper tends to shrink repeatedly as its outer face becomes wet from time to time (due to rain or dampness) and dries out, and that this shrinking action causes the marginal portions of the building paper to pull loose from the nails or other means for holding it in place upon the building. v
By constructing multiply paper in accordance with the present invention, so that the outer sheet of paper which is exposed to the weather is crimped or crinkled vthis outer sheet may contract and expand freely without rupturing or imparting its contracting action to the underl ing reenforcinfi material. It will there ore be seen t at the stretchable reenforced paper of the present invention forms an excellent building paper and that when the same is secured by nails or the like 14 to a portion of a building such as the boards 15 supported by beams 16, the overall dimension of the building paper will not be reduced by the contracting action of the outer or exposed sheet thereof, and as a result the paper will be permanently held. in place by the securin means 14 and will not pull loose as hereto ore.
When the paper of the present invention is to be used as a building paper, it may be suflicient to crape or crimp only the outer or exposed sheet of paper, since the inner sheet of paper which is not exposed to the rain and sun is not likely to'shrink sufiiciently to cause the multiply sheet of building paper to pull loose from its securing means,
at if only one face of the reenforced paper is crim ed care should be exercised to see that this and not the smooth uncrim ed face of the paper is exposed to the weat er.
The construction shown in Fig. 3 differs from the construction of Figs. 1 and 2 in that while the upper sheet 10 of the construction of Fig. 3 is craped or crim ed, the lower sheet 17 is a smooth straight sheet of paper. The 1 reenforcing fibres 12 and 13 of Fig. 3 may be the same as in Figs. 1 and 2.
It will be understood from the foregoing that the crinkles in a craped or crimped sheet of paper, not only render it elastic so that 1 it may stretch without tearing, but also decrease the gripping action of the adhesive u on the sheet of paper at the'raised ortion o the crinkles, to thereb facilitate t e contraction and expansion 0 this sheet of paper under different weather conditions relative to the reenforcing fibres.
The stretchable reenforced paper of the present invention therefore forms an excellent building paper that will stay in place 1" upon ex sure to the weather over along period 0 time, and is also well adapted for use as a wrapping paper and for other purposes where a strong and stretchable waterproof material is desired.
