ELASTIC PAPER SHEATHING AND METHIOD FOR PRODUCING THE SAME.
Application led February 24, 1922. Serial No. 538,921.
To all whom z't may concern Be it known that I, EDWARD H. ANGIER, a citizen of the United States, and a resident of Framingham, county of Middlesex, and State of Massachusetts, have invented an VImprovement in Elastic Paper Sheathings and Methods for Producing the Same, of which the following description, in connection with the accompanying drawings. is a specification, like characters lon the drawingslepresenting like parts.
This invention relates to paper sheathing for the protection of various kinds of goods or articles, such sheathing being useful either as an external covering for. the goods or as a lining for a more or less rigid container in which the goods are placed for shipment or storage. j
Many articles and many-kinds of goods need to be protected from contact with other articles or objects, and for such purposes it is customary to employ paper either as an enclosure in the form of a bag `or tube, or as a lining within some container such as a barrel or bucket. For many classes of merchandise it is desirable that the paper shall be elastic, particularly in the direction of the width of the sheath or lining, in order to accommodate itself to the internal shape of the container employed or to the external shape of the article enclosed by the sheath.
The present invention relates to the production of elastic paper sheathings for the purposes above mentioned and the object is to effect such production in a rapid, accurate and economical manner. The invention will best be understood by reference to the following description taken in connection with the accompanying drawings, wherein:
Fig. 1 is a partly broken fragmentary plan view illustrating an intermediate stage 1n the production of sheaths in accordance with my invention;
Fig. 2 is a similar view showing a later stage;
Fig. 3 is a perspective view of a sheath constructed as shown in Figs. 1 and 2 and 'adapted for use as a barrel liner;
Fig. 4 is a view similar to Fig. 1 illustrative of anothermethod of manufacture in accordance with my invention;
Fig. 5 is a fragmentary perspective view illustrating still another method of proceedm Fig. 6 s a. perspectiveview of a roll of sheaths adapted to be cut or torn' off one by l one as required;
Fig. 7 is a perspective lview illustrating a variation of Fi 5;
Fig. 8 is a similr view showing a further variation; and l Fig. 9 is a view similar to Fig. 4.illustrat ing a step in the production of sheaths for tennis rackets.
The showing of'craping in Figs. 2, 3 and 6' is diagrammatic and muchl exaggerated (the perforations 15. The two sheets 9 and 11 secured together in face to face contact are then subjected as a unit to a craping operation as, for instance, by passing the united sheets through a suitable bath and craping'them with roll and doctor in well known fashion to provide crapings runnin generally transversely of the two unite webs. The ,product of thisoperation is shown in Fig. 2 which in contrast with Fig.
1 shows how the paper is shortened by the process. It remains, however, capable of stretching out in well known manner with considerable resiliency.
The web may then bedivided transversely along the united areas 13, conveniently centrally thereof, and the lines of weakness 15, if present, will permit the se ments of the web to be torn olf or facih.-
tate the cutting. There is thus produced a fiat tube of paper as shown in Fig. 3 consisting of two side portions 9 and 11 united along the edges 'by adhesive seams. The
suprposed/layers of paper in these seamsf have .been craped as a unit and therefore the crapings of these portions are nested one within the other and the two layers of paper are interlocked in this manner as well as secured by thel adhesive joint. The result is a; joint of great strength as the adhesive was applied smoothly over the is capable of expansion since it partakes of the craping of the rest of the sheet. Con-- sequently a localized strain is not so applied as to start a break in the lioint but is distributed throughout the width ci, the
seam and also to laterally adjacent portions thereof.
The article produced as described may be opened out as shown in Fig. 3 for use as a barrel liner. For such use a disc of paper would iirst be laid in the bottom ot the barrel and then a' tube placed inside the same. If the barrel is then iilled' with some pulverant or granular material, such as sugar, the crapings will permit it to expand to the form oi the barrel without breaking and provide a liningfor the same eifectually preventing sifting of the Ycontents between the staves. i
The tube shownl in Fig. 3 is open at both ends. To form a' bag a tube may be produced closed at one end 4and for such purpose the webs of paper may be united by one or more longitudinal stripes oi adhesive connecting the transverse stripes. In Fig. 4 I have shown an arrangement wherein two webs of paper 9 and 11 are united by a central longitudinal stripe 16 of adhesive intersecting the transverse stripes 13 corresponding tothe stripes 13 in Figs. 1 and 2. In Fig. 4 the web may be divided centrally of the stripes 12'a and centrally of the stripe 16 providing bags with closed bottoms of a depth equal to halt the width of the web. Of course, a variation in the position of the Stripe 16 varies the width ot the bag formed and in the limiting case the stripe would be applied at one edge of the webs and the bags would be fewer innumber but of the full depth ot the width ot the webs.
in Figs. 1, 2 and Ll the two layers of paper are separate webs but tor certain purposesv they may be made by folding a single web on itself and the iolded edge may be'utilized as a marginal portion of the completed sheath. Referring to Fig. 5, l have shown a web oi paper 17 having A both edge portions folded over on the iace providing folded edges 19 and 21. and united by transverse stripes oi adhesive 23. Such a web may be craped and divided along the middle where the folded over edges meet and transversely along the stripes 23 providing bags having adhesive seams at the sides and folded at the bottom, these bags being of a height equal to half the width of the olded web. ln llig. 7 a web 17a is Moneta Shown folded downing middle to provide one folded edge 19a, the two portions of the' web being united by transverse stripes of adhesive 23a. -lf this web is craped and- ,center long tubes having one folded and one adhesively secured edge are provided which is an example of afolded joint combined with a longitudinal adhesive joint.
in the construction described the adhesive is applied in regular lines and the sheathings produced are correspondingly regular. To protect articles which are irregular in form, for instance, to provide sheathngs for um'- brellas, guns, tennis rackets, or the like, the adhesive joints and the lines of. severance may be more or less irregular corresponding to the proper contour ofV the desired sheath and a folded edge portion similar to 19 and 21 in Fig. 5 maybe utilized in combination with an adhesive suitably applied to a limited area of the paper to define all or a portion of the contour of any desired shape of sheath. ln Fig. 9 I show twov webs 9c and 11 joined by adhesive along areas 13 which are of suitable contour to provide when the webs are cut, partly along the contours 13' and partly along lines 27, open ended sheaths each adapted to tit a tennis racket.
in Fig. 6 l have illustrated the craped double web shown in Fig. 2 as rolled up may be divided into suitable lengths. rlhis providing a supply from which individual oi barrels to be lined also known, the total length of dat paper required to Vll the order can be determined by simply adding to the total oi all the internal semi-circumierences enough to slightly exceed the measurement required to allow for the. Widths `ot the transverse stripes 13 and any desired residual craping. No matter how much the duplex paper is afterwards shortened by the craping process, each'sheath or lining will be capable of stretching to bear against the inner surface of the barrel. A lf a customer wishes a twenty per cent stretch to allow for the bilge of the barrels, this can be allowed for when the paper is fiat and the correct result obtained. For all pur oses it is easy to estimate how much paper s all be allowed for those areas which are not adhesively united so that those areas,
after craping, will stretch without tearing when applied to iinal use.
Having described in detail certain illustrative embodiments of my invention.' in order to indicate the varied operations which may be followed and within the scope thereof, the principles exemplified thereby which I claim as new and desire to secure by Letters Patent I shall express in the following claims.
