Moreover, only the one edge area 11, of the Similar reference characters indicate correlining '7, is joined to the under side of the edge 100 4* spending parts throughout the several views of area 1'7, as indicated at numeral 15. The edge the drawing. area 1l, however extends substantially beyond A conventional mode of fastening or seaming the end of the edged area 17, as noted at numeral edges of lined Woven fabrics comprises overlaying 12. The position of the remaining edge area 19 V two or more layers of fabric and lining and sewis determinedfby the material located within the "0 ing therethrough a strand such as a thread, cord, bag, and may vary sincei't is in no way fastened twine or the like. This method of fastening or at the seam 9. seaming has certain disadvantages arising from As the edge areas 17 and 19 are brought tov vseveral causes. For example, stresses applied to gether to form the seam 9, a layer of adhesive the sewed seam are concentrated at points material or cement 21 is positioned between the 110 through Which the thread passes. Thus the areas 1'7 and 19 in a layer extending substantially along the areas. At the same time the edge areas 11 and 13 are positioned beneath the area 17, the area 11 coming directly in contact therewith as is shown more clearly in Fig. 2. The edge of the lining '7 extends substantially beyond that of the material 5 as shown at numeral 12. The` cement or adhesive material comprisespreferably latex, processed rubber, gum, asphalt or any ad- .the lining 7 enlarges by the sliding of the edge hesive capable of forming a seamof sufficient strength. The layer on one side faces the woven material of the edge area 19, and on the other the edge area 17.

I t is appreciated however, that the liquid cement tends to readily passv through the reticulated mass of the material 5 (burlap, for instance), and is received by the edge area 11 of the lining 7 which, being paper of the like, is substantially impervious to the passage of the cement 21. Thus the cement 21 does not reach the area 13, of the lining '7, and accordingly the area 13 is left free to slide past the area 11. In this way the perimeter of the cylinder formed by the lining is made variable as is clearly shown in Fig. 3. r

The joint formed between the three edge areas 17, 19 and 11 is particularly effective. The cement surrounds and embedsl the outstandingv fibers of the woven material' 5, passes into the interstices thereof. Thus, there is effected a substantially homogeneous material at the juncture between the fabric, the lining and the cement. It will be understood that a compressing operation is used in juxtaposing the edges of the material 5, so that in actuality the seam 9 is only slightly thicker than the material composing it and thus is substantially thinner than is diagiarnmatically shown in Figs. 1 and 2. The width of the overlapping area between the edge .areas 17 and 19 may be varied as is desirable to obtain a proper strength in the seam 9. The joint may be made stronger than the remainder of the bag by using an amply wide area, al though this is not necessary be limited to provide substantially equal strength.

It is thus seen that a bag 1 has been provided which isy adapted to receive rolledA material 3 comprising cloth, rugs or the like and to provide protection from moisture, dust, moths and the 50. like. In order to cover such a piece of material as a rug, with the bag 1, the latter is opened up to form a cylinder, and the rug 3 ktelescopingly placed therein. In this operation the lining '7 is only opened up far enough to receive the rug 3, the free edgearea 13 sliding pastY the edge area 11, thereby permitting the lining '7 to conform to the shape of the object 3, which is being received into the bag l. It is thus seen that the lining 7 bears substantially none of the stresses or strains due to the load which the bag or cover 1 carries. As the bag stretches, the periphery of area 13 past the edge area 11. Such however, would not be the case if the edge area 13 were fastened to the edge area 11.

After the rug or rolled'material 3 is located and the area may' within the bag 1, ends 23 of the bag 1 are suitably closed as is shown in Figs. 4, and 5 and 6. Fig. 4 shows one method of fastening the ends 23 and involves winding a strand of twine, wire or like substance 25 around that portion of the bag 1 which extends beyond the material bagged. Figs. 5 and 6 show the closing accomplished by flattening the portion of the bag which extends beyond the roll 3, folding it back on itself, and sewing the juxtaposed portions together, near the fold.

An advantage of the invention is the flexibility with which the lining '7 is secured within the woven fabric 5, whereby substantially all of the strains resulting from bagging the material 3 are properly borne by the woven material 5. Another advantage is the ease with which such a bag is manufactured, the durability and protection which it offers. Another advantage presented by the invention is 'the fact that the paper lining is not weakened by perforations formed by sewing. Further it is not necessary to wrap the ring or other contents in paper before inserting them in the cover.

In View of the above, it will be seen that ithe several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructions'without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting Sense.

We claim:

v1. A container comprising an inner lining having outer and inner lateral edges, said edges being juxtapositioned, an outer reticulated fabric also formed to provide juxtaposed edges, and permeable' adhesive material for binding together said fabric juxtaposed edge areas and said outer lining edge.

2. A container having an outer fabric layer formed to provide lapped fabric areas, a lining in said container formed to provide lapped lining areas, said lining areas being positioned opposite said fabric areas, cement positioned between said fabric areas, and between said fabric areas and said lining, said fabric areas being pervious tol said cement, and said lining being substantially impervious to said cement, whereby one lapped area of said lining is joined to said fabric and the other edge of said lining is left free to vary in position.
