This figure also illustrates a and is not so apt to crack under the strain of guiding device for the second strip; crimping. The strip 3, as illustrated, is

Fig. 4 illustrates a sectional view of the wider than the strip 1 and is coiled around two rings formed by coiling the second strip the ring 4; formed of the strip 1 into a ring 55 around the first strip; 5, the strip 3 being coiled twice around the- ]11@- tion, before the craft paper strip 3 is coiled around the ring 4, that face of the'craft paper strip which is to be the inner face of the coils, 'istreated with sizing as, for instance, animal glue, which is permitted to become dry before the craft paper strip is utilized to form the coil. ,The full width of the craft paper strip is so treated, in the present embodiment, and just before the coiling thereof is effected that part of the width of the strip which registers with the first ring 4 is moistened so as to provide an adhesive face or coat which will stick to the outer face of the ring 4 when coiled there- .around, and so that the plies of the ring of craft paper will be secured to each other for a part of the width of the craft paper ring. That part of the width of the multiple-ply craft paper ring which extends beyond the end of the ring 4, as indicated at 9 in Fig. 3, will have the unmoistened and consequently dry sizing on its inner face and between the plies thereof. Thus the dry sizing has a non-adherent outer face between the plies of the extended portion 9 of the craft paper ring. In Fig. 3 the coat of sizing is indicated by the stippling, the dotted line 90 indicating the meeting line of the dry and moist sections.

The coiling of the strips 1 and 2 may be effected on a rotary cylindrical mandrel, or form, and the strips 1 and 2 supplied to the mandrel by any suitable feed device. In the embodiment illustrated, however, the craft paper strip 3 is yieldingly pressed lat-- erally as it is fed so that its edge, as 7, lies in predetermined relation to the edge 8 of the ring 4 on which it is coiled. As illustrated, the craft paper strip 3 lies in a guide channel 10 in a strip support 11. A springpressed guide. plate 12 yieldingly presses against one edge of the strip 3 so that the opposite edge is pressed against the wall of the channel and thereby in line with the edge 8 of the rim 4.

Referring to Fig. 3, the inner edge 13 of the first multiple-ply ring forms a shoulder intercepting the wall of the second multiple ply ring 5 or craft paper, and this shoulder provides a continuous support for a head, which may be a domed head, as illustrated at 14, Fig. 10, or a flat head as indicated at 15,'Fig. 12. In the embodiment of the box illustrated a flat paper disk or additional" ornamental surface to the ring 5.

By the provision of the multiple -ply ring,

5 with sizing between the plies, as described,

an article is formed which lends itself readthe plies of the ring 5 being folded inwardlyv or curled to form a bead, or crimp, 17, which will press down upon the head 14 and maintain it in osition, all as indicated diagrammatica y in Figs. 12 and 14. The softening of the sizing is effected, in the present embodiment, by heating the extended portion 9 of the multiple-ply ring of craft paper. This may be conveniently done by providing a heated crimping die and bringing the sized extended portion 9 of the ring 5 into contact with the die and letting it remain in contact therewith for a short time prior to effecting crimping. Thus the unmoistened sizing between the plies of the extended portion is softened and in condition to fasten together the plies of the extended portion of the ring 9 by causing them to adhere to each other. By the crimping operation the plies are turned inwardly and they readily, as it were, fold and slide upon each other, while the sizing is soft, so that the crimping operation is effective and neat. After the crimping operation the crimped parts are permitted to cool and this effects the hardening, or setting, of the sizing which thereby retains and holds the folded plies in crimped form.

\Vhereas the multiple-ply ring of craft paper with sizing between the plies, as described, lends itself readily to the crimping operation hereinbefore set forth, it is desirable in many instances to cover the craft paper ring with ornamental material and to bind the edges of the plies of craft paper together prior to and during the crimping operation. To thisend a binding strip 20 (Fig. 5) is applied onthe outside of the multiple-ply ring 5, the edges of this binding strip extending beyond each of the opposite edges of the craft paper ring. This binding strip may be of very thin material, thinner than the card middle strip. or the craft paperfand may be printed, coated or otherwise ornamented so as to give a desired In the present embodiment the binding strip 20 is a gold strip, that is to say, one face has a golden appearance. Its opposite surface is given a thin coat of glue in order that it may adhere to the ring 5. The strip 20 having been coiled once around the ring 5 and cut off, the opposite ends of the resultant gold ring are folded across the multiple-ply edges of the assembled rings 4: and 5 and into and against the inner surface of said rings, as illustrated at 21 and 22, Fig. 7. In effecting the folding across the edge of the extension 9 of the multiple-ply ring 5, a roller 23, Fig. 9, is employed which is yieldingly pressed towards the edge of the ring during the folding operation and thereby makes the fold of the binding strip closely conform to the edge of this ring even though this edge be somewhat irregular. It is to be understood that the coiling of the strips 1, 3, and 20 into rings is effected by rotating the mandrel or form, and that the folding of the gold strip 20 at 21 is efiected by the roller 23, as the mandrel rotates and as this strip is wound around the ring 5. Proper pressing rollers may be employed to assure that the coiling shall be smooth and tight. The provision of the folded thin binding strip 20 not only serves to ornament the outer faceof the craft'paper ring 5 but surrounds the dry-sized end of the craft paper ring and prevents access of extraneous matter as dust, atmospheric moisture, etc. to the sizing between the plies. The

' paper of which the binding strip 20 is composed, however, is thin and does not interfere with effective crimping. The adhesive for the binding strip is of relatively thin consistency and this and the thin binding paper 20 at the crimped edge merge with and form part of the crimp when the sizing is softened by heating the ring at its bound edge.

By the method herein described it will.

be perceived that a crimped paper ring is produced in which the crinipis set by the sizing, the sizing becoming hard and stiff and thereby setting the paper in crimped form. By the use of relatively thin paper coiled into ringform, as explained, aring of any practical thickness may be made and'efiiciently crimped.

In Fig. 12 of the drawing is illustrated a box in which the base 24 and the lid 25 are made in accordance with the method hereinbefore described. The box illustrated is designed to hold face powder and is provided on its interior with. a cover '26 of imperforate frangible fabric, such as thin paper. The cover 26 at its edge is secured to an interior multiple-ply flange 27 which conforms to the shape of the inner wall of the base 24 and is adhesively secured to said inner wall. Likewise a portion of the flange 27 extends above the open end .of the base and forms a neck with which the lid teletain accesst'o the powder in the box, the lid 25 is removed and the cover 26 broken, as by pressing a finger against it.

To fold the projecting eges of the binding To ob-.

On account of the gathers or puckers in thefolded edges of the binding-ring there is a tendency for the folded edges to pop or spring from the opposite edges of the multiple-ply ring. To avoid this possible separation, the edges of strip 20 are pressed closely against the opposite edges of the multiple-ply ring for the full thickness of the edges of the multiple-ply ring, the shoulders 28. of the rollers 23 being as deep or a little deeper than the thickness referred to. In this wise the folded edges lie in close contact with the edges of the multiple-ply ring, and the folded material, due to the puckers, takes up a position pointing inwardly of the multiple-ply ring, as indicated by the dotted lines 29, Fig. 9. In this wise,

-each folded edge of strip 20 maintains its after the edges of strip 20 are folded by the rollers 28 as the multiple-ply ring ro-' tates with the mandrel, the disk folders 30 and 31 move axially, the perimeters thereof wiping the folds. into the paper ring and against the inner wall thereof.

Preferably the disks 30 and 31 are so mounted as to rotate as the paper ring rotates, and the wiping of the folds into the paper ring occurs while the paper ring and said disks are rotating.

As many changes could be madein carrying out the above method, and in the above apparatus, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. v F
