12 Claims.

The present invention relates to spools and, in its more specific aspects, is concerned'with. spools for carrying rolls of narrow fabrics such as rib.-' bons, bands, tapeaetc. The invention is also concerned with a novel method of mounting rolls of material on packaging spools. r Y V Narrow fabrics such as ribbons; tapes, etc are usually Wound on pre-formed spools having cylindrical coresyand ribbon manuiacturersarerel quired' to keep in ,stock' large quantities of such spools. As the necessarystockoi spools takes up a lot of room, pro-formed spools: are for that reason, among other things, undesirable. It is there-- u fore an object of this invention to obviate the W necessity for the manufacturer to keepin stock preformed spools and, for that purpose, to provide spools which can be readily formed from blanks of sheet material, large quantities of which may kept in a relatively small space and made 25 up into the spools asneeded.

Another object of the present invention is to provide a spool of such construction that it can be formed fromsheet material by simple mechanical operations such as cutting and folding.

A further object of the invention is to provide an improved method of mounting rolls of ribbons, tapes and other narro fabrics on packaging spools. Y

A further object of the invention is-to provide a 30 spool of improved appearance whereby to enhance the ornamental appearance of the ribbon roll or package, and thus favorably impress the prospective purchaser and promote the sale of the ribbon.

A yet further Object of the invention is generally to provide narrow-fabric or other spools which are simple in construction and which can be produced at low cost.

. The above objects of the inventionand other 2m objects ancillary thereto will best be understood from the following description considered with reference to the accompanying drawing forming apart of the present specification.

In the drawing: V r V Fig. l is a perspective view-of a spool embodying the present invention; a

Fig. 2 is a plan view of a blank of sheet material from which the spool shown in Fig. 1 is formed; 50 Fig. 3 is a sectional view on the line 3--.'i of Fig. 1;

Fig. 4 is a perspective View of a spool having a roll of ribbon wound thereon; Fig. 5 is a view'similarto Fig. 1, showing a modification;

in connection with the Fig. 6 is a perspective view, on a reduced scale, of a roll of ribbon mounted on a temporary carrier, and illustrates one step in the present method: a

Fig. 7 is a View similar to Fig. 4, illustrating a 5 'further form'of the invention, and another. step board, fibre-board, stiifened fabric, or thin bend- 5 able metal, although for the purposes of the present invention and especially in order to keep down the cost of the spools, said blank is made preferably of cardboard.

As here shown, the blank ii. is generally circular in peripheral outline and has a central opening i i-oi octagonal outline defined by the inner edges iii of the rectangular sections l8. Said sections iii are defined by scoring said blank along spaced lines 29, extending outwardly at right angles from the inner edges is and constitutingfold lines for forming the spool 50 from theblank. Said fold'lines 28 are arranged in pairs, the lines of each pair being disposedin diverging relation and extending from the meeting ends of adjacent 30 edges iii to the outer periphery of the blank beyond the outer edges I9 of the rectangular sections I8, thereby defining together with an arouate circumferential edge 22 a section 24 which is in the form of a sector of a circle, or substantially in the form of a triangle. Thus, the blank 12 comprises alternate rectangular and substantially triangular sections l8 and 24, respectively, disposed circumferentially of the blank about the central opening i l. Said blanks may be; produced in largequantities by die-cutting the same from the sheet material. i

In forming the spool ID from the'blank E2, the latter is folded along pairs of fold lines 26 alter- 4r nately in opposite directions, forming substantially triangular side-wall portions 313 and 32 at opposite sides, respectively, of the spool, providing the spool flanges and intermediate wall portions 3d formed from the rectangular sections it, providing the spool barrel. Said intermediate wall portions are disposed axially of; the spool between the sides of the latter and are arranged in pairs extending radially in V-oonfiguration. When the blank is thus formed into the spool, the

block or expander member outer edges 35 of the intermediate wall portions 34 are spaced circumferentially of the spool and constitute the support or barrel for the ribbon R wound thereon, and the inner edges 36 of said intermediate wall portions 34 meet centrally of the spool and extend along a line axially thereof between opposite sides of the spool. The edge portions 3| of the side wall sections 30 extend radially beyond the edges 35 of the intermediate wall portion 34, forming flanges for retaining the roll of ribbon on the spool between the sides of the latter.

Instead of winding the ribbon directly in con-' tact with the edges 35, an annular band 38 of paper or other suitable material may first be secured circumferentially of the spool in engagement with said edges, thereby holding the folded blank in the spool formation. This alternative construction is illustrated in Fig. 5.

In the form of the invention illustrated in Figs. 6 to 8, and in accordance with the present method of mounting rolls of ribbon on the spools, there is utilized a spool l0, but instead of winding the web of ribbon directly on the spool, said web is first wound into a roll Ra on a temporary carrier such as a cylindrical spool or mandrel 39 of any suitable form, after which said roll is removed from the temporary spool and mounted on the spool IB. While I have illustrated a single roll mounted on the temporary carrier therefor, it will be understood that in practice a relatively large number of said rolls may be wound on a single spool of suitable length, being disposed axially of said spool and readily removable therefrom for mounting on individual packaging spools ii]. In order to permit the wound roll to be placed on the spool II], the temporary spool or mandrel 39 is of such size as to provide a central opening in the roll Ra large enough to enable said roll to be slipped over the flanged ends 3! of the spool when the spool is in contracted condition with the inner edges 36 thereof in engagement with each other. After the wound roll has been placed upon the spool, a cylindrical 40 of wood or other suitable material is inserted between said edges 36, thereby expanding the spool and forcing the edges 35 of the intermediate wall portions 34 of the spool into engagement with the inner convoluticn of the roll of ribbon.

It will be understood that the roll of ribbon may be wound on the spool in together with a protective paper strip disposed between ribbon convolutions, or when the roll is first wound and subsequently mounted upon the spool l0, said protective paper strip may be wound together with the ribbon on the temporary spool or mandrel 39.

While I have shown and described several of the preferred embodiments of my novel spool construction and the method of packaging rolls of ribbon in accordance with the present invention, it will be understood that the invention is capable of other embodiments than those herein shown or described and that each of the embodiments herein disclosed may vary as to details of construction and arrangements of parts. Therefore, I do not wish to belimited precisely to the present disclosure or to any part thereof, except as may be required by the appended claims considered with reference to the prior art.

Having thus described my invention, what I desire to claim and secure by Letters Patent of the United States is:
