RIBBON REEL Application filed April 8,

This invention relates to improvements in ribbon reels and has articular reference to a reel upon which rib on is wound in hank form.

An object of the invention is to provide an improved reel of practical and inexpensive construction wherein the ends-of the reel, about which the ribbon is wound and which provide supports for the ribbon to retain the same in its wound condition, constitute a art of the single blank of material from which, the reel is constructed.

The above and other objects will appear more clearly from the following detailed description, when taken in connection with the accompanying drawing, which illustrates a preferred embodiment of the inventive idea.

In the drawing- Figure 1 is a plan view of the blank from which the reel is made;

Figure 2 is a side elevation of the reel in its completed form with a hank of ribbon wound thereon;

Figure 3 is an enlarged longitudinal section of the reel before the ribbon is wound thereon;

Figure 4 is a similar section with the ribbon in place; and

Figure 5 is a section Fi ure 4.

eferring to Figure 1, there is shown a blank which may be of any suitable material, such as fairly stiff paper or light cardboard, and from which the reel is formed. The blank is out and scored to provide the opposed complemental side sections 6 and 7 and an intermediate ribbon-supporting edge section 8, the latter extending along portions of the peripheries of said side sections and terminating at its ends in extensions 9 which form end supports for the ribbon when the latter is wound upon the finished reel, as will appear in the course of the description. Outer ribbon-supporting edge sections 10 and 11, similar to the section 8, are formed along the outer edges of the sections 6 and 7, respectively, and when the blank is folded on the indicated dotted lines, said sections 10 and 11 are on the line 55 of 1931. Serial No. 528,572.

overlapped and secured together by a suitable adhesive. Either of the sections 10 or 11, in this instance the former, is provided at its ends with extensions 12 similar to the extensions 9 and opposed thereto when the reel is in its assembled position, as shown in Figure 3.

Before the blank is folded to form the reel, the side sections 6 and 7 each has cut therein adjacent its rounded ends the openings 13 which align with the adjacent openings in the other section, when the reel is assembled, so as to receive a rod or pin (not shown) which is utilized while the ribbon 14 is being wound upon the reel. As this winding operation is started, the first turn or convolution of the ribbon engages the rods or pins at the ends of the reel and at the same time flexes the opposed extensions 9 and 12 inwardly toward each other, as indicated in dotted lines in Figure 3, the position of the openings relative to said extensions being such that the latter will assume,

' under pressure of the ribbon-thereagainst,

an arcuate contour substantially in alignment with the portions of the surfaces of said rods which are enga ed by the ribbon. Thus, while the ribbon is ing wound upon the reel, the'rods and extensions form supports therefor and cause the superimposed layers to assume a rounded form at the ends of the reel. After said rods are withdrawn from the openings 13 at the conclusion of the winding operation, the extensions 9-and 12 will continue to provide supports for the ribbon, as illustrated in Figure 4, by reason of the outward pressure of the flexed extensions against the innermost convolution of the wound ribbon, and the extremities of the side sections 6 and 7, beyond which the layers of ribbon do not extend, will maintain said layers in superimposed relation. To further prevent dis lacement of the layers of ribbon between tlie ends of the reel, a flexible band 15, which may consist of a strip of paper, is secured around the ribbon and reel transversely thereof.

What is claimed is:

l. A ribbon reel comprising edge sections upon which a length of ribbon is to be wound, and opposed extensions at each end of said ed e sections flexed toward each other by said ribbon to form arcuate supports therefor.

l 2. A ribbon reel comprising side and edge sections, said side sections having openings therein adjacent their ends, and said edge sections having spaced opposed ribbon-supporting extensions at their ends flexed to- 10 ward each other by a ribbon Wound thereon so as to assume an arcuate formation the contour of which substantially aligns with a portion of the edge of the adjacent open- 1n 15 A ribbon reel formed from a single blank of flexible material scored to provide side and edge sections, and flexible extensions at each end of said edge sections flexed toward each other by a ribbon wound on the latter sections to constitute supports for said ribbon which exert an outward pressure thereon.

In testimony whereof, we have aflixed our signatures.
