Filed Feb. 19, 1971, Ser. No. 116,869 Int. Cl. B65h 75/06 US. Cl. 206-50 7 Claims ABSTRACT OF THE DISCLOSURE A cloth-board reel is provided with a core made of plastic material. The core is provided with flat, substantially wide oppositely facing fluted sides and rounded narrow longitudinally extending edges. Tightly wrapped about the core is a sheet of rather heavy paper stock which covers both sides and both rounded edges of the core, having the two ends of the core uncovered.

BACKGROUND OF THE INVENTION (1) Field of the invention This invention relates generally to reels, and particularly to improvements in cloth-board reels for carrying cloth wound thereabout.

(2) Description of the prior art My US. Pat. No. 3,286,828 discloses a cloth-board reel fabricated entirely of paper stock and extremely staunch, durable and reliable under all conditions of use. Attempts have been made to replace this type of reel with one extruded, molded or otherwise formed entirely of plastic material. While such reels may be less expensive to fabricate, they have not proved to be entirely satisfactory because they do not stand up sufliciently well under the abuse they receive in normal use. In particular, they do not have the strength necessary to withstand the torsional and buckling stresses to which they are subjected during machine winding of cloth on the reels.

In addition, when cloth is wound on a reel, it may not be completely free of moisture. In order to prevent moisture being trapped between the reel and the innermost coil of cloth wound thereabout, the interface therebetween must be vented to atmosphere and/or the moisture must be absorbed by the reel by capillary attraction. Since plastic material is impervious to air and incapable of absorbing moisture by capillary attraction, a reel made entirely of plastic material is not suited for the purpose intended for moisture is trapped at said interface and as a result the cloth may be damaged by the formation of mildew.

Furthermore, it has been found that a fine powder forms on the outer surface of a reel made entirely of plastic material, and that the powder adheres to the cloth when the cloth is removed from the reel.

SUMMARY OF THE INVENTION A principal object of the invention is to provide a cloth-board reel consisting of a core of plastic material made extremely staunch, durable and reliable under all conditions of use by reason of being tightly Wrapped, encased or jacketed in a sheet or sleeve of rather heavy paper stock.

Another object of the invention is to provide such a reel wherein the outer surface areas of the core are fluted so as to place the inner surface areas of the paper stock sheet directly in communication with atmosphere.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a cloth-board reel constructed in accordance with the invention, parts being broken away to expose others;

1 FIG. 2 is an enlarged section on lines II-II in FIG.

; and

FIG. 3 is a perspective view of the cloth-board reel, showing a length of cloth wound thereabout.

The following description is directed to the specific embodiment of the invention disclosed in the drawing. It is not addressed to the scope of the invention, which may be practiced in a variety of forms.

Referring particularly to the drawing, a cloth-board reel constructed in accordance with the invention, generally designated 10, comprises a semi-rigid core 12 preferably made of a comparatively inexpensive, light weight polymeric material, such as low density foamed polystyrene, and measuring, for example, 8" x 1" x 1'-6". The core may be extruded, molded or otherwise formed of such material, and is provided with oppositely facing wide, fiat sides 14 and '16 and rounded longitudinally extending narrow edges 18- and 20-, as shown. The side 14 is provided with a series of four longitudinally extending laterally spaced flutes or grooves 22 each extending the full length of the core, and the side 16 is provided with a series of four longitudinally extending laterally spaced flutes or grooves 24, staggered, as shown, relative to the groove 22, each extending the full length of the core.

The core 12 is tightly wrapped or encased in a sheet 26 of foraminous or perforated paper stock adhesively applied to the core. The sheet 26, of rather heavy paper stock, extends completely around the core to form a butt joint 28, as shown. Only the opposite ends of the core remain exposed. Lined chip paper stock .016 of an inch thick and provided all over with perforations or foramina 1" on centers and M2" in diameter, designated 30', has proved to be entirely satisfactory for the purpose intended.

A cloth-board reel constructed in accordance with the invention is a unitary structure the core 12 of which is rendered rigid by the paper stock sheet 26. Such a reel is economical to fabricate, light in weight and extremely staunch, durable and reliable under all conditions of use. In addition, air flowing freely through the reel via the

flutes

22 and 24 comes into direct contact with the paper stock sheet 26. Thus, moisture drawn by the sheet 26 (by capillary attraction) from the cloth wound thereabout is carried away to atmosphere and the development of mildew is thereby arrested. Some or all of the perforations or foramina 30 may be arranged to register with the

flutes

22 and 24. In this event, the outer surface areas of the paper stock sheet 26 are vented to atmosphere through such perforations or foramina 30 and the

flutes

22 and 24, and air flowing through the reel via the

flutes

22 and 24 comes into direct contact with the cloth wound about the reel, whereby to draw moisture therefrom and thus aid in preventing the formation of mildew. Furthermore, the core 12 is clad in the paper stock sheet 26, as a consequence of which the cloth wound about the reel does not come into direct contact with the core 12. Thus, when the cloth is removed from the reel, it comes off clean, i.e., free of any fine powder shed by the core.

While in accordance with the provisions of the patent statutes, I have illustrated and described the best form of the embodiment of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the cloth-board reel described without departing from the spirit and scope of the invention as set forth in the appended claims, and that in some cases certain features of my invention may be used to advantage without a corresponding use of other features. For example, the

flutes

22 and 24 all extend parallel to the longitudinal axis of the cloth-board reel and in a straightline from one end to the other thereof. This feature is not essential. The desideratum is at least one flute extending into the reel from one end thereof. The flutes need not extend from one end to the other thereof, and they need not be straight and/or parallel to the longitudinal axis of the cloth-board reel. in fact, one flute spiraling about the core 12 could be adequate for the purpose intended. By way of further example, the entire outer surface of the core 12 could be corrugated by providing it with a series of close adjacent flutes. Still further, by way of example, when it is desired to avoid fluting the core 12, a sheet of perforated or foraminated single face corrugated paper stock may be substituted for the sheet of lined chip paper stock 26, the corrugated face of the sheet being disposed on the inside and being adhesively applied to the core 12. Moreover, while the core 12 is shown and described as a solid mass of plastic material, it will be understood that the interior thereof may be made hollow and ribs may be provided internally thereof to render the core at least semi-rigid.

-What is claimed is:

1. In a cloth-board reel, the combination of:

(A) a core of plastic material having oppositely facing substantially wide sides and rounded longitudinally extending narrow edges,

( B) a sheet of porous paper stock extending completely about said core and adhesively applied thereto thereby to form therewith a unitary structure, said paper stock being of a weight and thickness suflicient to render said unitary structure rigid, and

(C) flute means between said core and paper stock sheet operative to place inner surface areas of said paper stock sheet in communication with atmosphere.

2. The combination according to claim 1 wherein the outer surface of the core is provided with flute means extending into the reel from an exposed end thereof.

3. The combination according to claim 1 wherein the outer surface of the core is provided with flute means extending into the reel from both exposed ends thereof.

4. The combination according to claim 2 wherein the paper stock sheet is foraminated and at least some of the foramina register with the flute means.

'5. In a cloth-board reel, the combination consisting of:

(A) a core of low density foamed polystyrene having oppositely facing substantially wide sides and rounded longitudinally extending narrow edges,

(B) a sheet of stiff, heavy paper stock extending completely about said core and leaving the ends of said core exposed, said sheet being adhesively applied to said core thereby to form therewith a rigid unitary structure, and

(C) a series of laterally spaced flutes in the flat, substantially wide sides of said core extending longitudinally of said core from one end to the other thereof parallel to the longitudinal axis of said reel.

6. The combination according to claim 5 wherein the paper stock sheet is provided with foramina which register with the flutes.

7. The combination according to claim 5 wherein the flutes formed in each of the flat, substantially wide sides of the core are staggered relative to those formed in the other of said sides.
