PACKAGING COVERS FOR comma SHEET MATERIAI;

Filed. March 8, 1957 y a w United States Patent PACKAGING COVERS FOR COILED SHEET MATERIAL Alvin A. Abramson, St. Louis, Mo., assignor to Central States Paper & Bag 'Co., St. Louis, Mo., a corporation of Missouri Application March 8, 1957, Serial No. 644,845

7 Claims. (Cl. 206-59) This invention relates in general to packaging and, more particularly, to a packaging cover for coiled sheet material.

Sheet metal as it comes off of a rolling mill is usually wound into hollow cylindrical coils so that the sheet metal can be conveniently handled, shipped, and unrolled when the metal is ultimately used. However, the coil of metal is subject to exposure to dirt, water, and other corrosive elements, and, furthermore, the exposed side edges of the sheet forming the coil are frequently sharp and are, therefore, likely to injure persons or objects which might contact them. Consequently, it is desirable to package the coil in such a manner that it is completely enclosed within the packaging cover. In addition, the packaging cover should fit snugly over the coil and must be applied in such a manner that it will not accidentally open or tear when the coil is handled. It is also desirable that the packaging cover be relatively inexpensive and capable of quick application to the coil.

It is, therefore, one of the primary objects of the present invention to provide a packaging cover for coiled sheet metal and the like which snugly and completely encases the coil.

It is also a primary object of the present invention to provide a unique and highly efficient method pack-aging coiled sheet metal and similar materials.

It is also an object of the present invention to provide a packaging cover of the type stated which will not become accidentally opened or torn.

It is an additional object of the present invention to provide a packaging cover of the type stated which is formed of a plurality of pre-cut pieces which can be quickly and easily applied to the coil.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

In the accompanying drawing- Fig. 1 is a perspective view of a coil of sheet material enclosed in a packaging cover constructed in accordance with and embodying the present invention;

Fig. 2 is a fragmentary sectional view taken along line 2-2 of Fig. 1;

Fig. 3 is a bottom plan view of a side cover sheet forming a part of the present invention;

Fig. 4 is a perspective view of the core tube forming part of the present invention;

Fig. 5 is a perspective view, partly broken away and in section, of the core tube of Fig. 4, and showing the core tube opened out;

Fig. 6 is a top plan view of the outer cover sheet forming part of the present invention; and

Fig. 7 is a fragmentary bottom plan view of the outer cover sheet shown in Fig. 6.

Referring now in more detail and by reference characters to the drawing, which illustrates a preferred embodiment of the present invention, A designates a packaging cover formed of plain, reinforced or treated heavy kraft paper or suitable plastic sheet, which encloses a 2,883,045 Patented Apr. 21, 1959 hollow coil of sheet metal B and comprises a rectangularly shaped outer cover sheet 1 having opposite faces a, b. The face a is provided along its longitudinal margins and one transverse margin with connecting bands of pressuresensitive adhesive 2, 3, 4, and the face b is provided along the remaining transverse margin with a similar band of pressure-sensitive adhesive 5. It has been found in connection with the present invention that one suitable type of adhesive for the bands 2, 3, 4, 5, is an aqueous dispersion of latex of which the following is a preferred example:

Percent by weight Rubber 42.2

This adhesive has the unique and interesting property of being relatively non-tacky when thoroughly dry so that it will not adhere to any other external surface, but will bond almost instantaneously to any surface which is also coated with a dry film of the same adhesive.

Provided for insertion within the core of the coil B is a coreliner 6 which, for convenience in storage prior to use, is made from a rectangular sheet of kraft paper or plastic material folded lengthwise and overlapped in the provision of a seam 7 to form a flattened tube as shown in Fig. 4. When desired, the latter can be opened out to the cylindrical form shown in Fig. 5. Since the diameter of the winding mandrel is standard in any steel mill, the core-liners can be made up to a predetermined size and will fit inside all rolls of steel wound thereon. However, the outside diametral size of the rolls may vary considerably depending upon the gauge of steel being wound and the number of turns applied to the roll. Consequently, the outer cover sheet 1 must be of such length as to cover such variations within reasonable limits, which is the reason for the two transverse bands of adhesive 3, 5. On its inner surface and adjacent its outer edges the core-liner 6 is provided with annular bands of adhesive 8, 9, preferably of the same composition as the adhesive previously described. Provided for covering the edges of the coil B is a pair of fiat circular side cover sheets 10, 11. As seen by reference to Fig. 3, the side cover sheet 10 is provided with a central aperture 12 surrounded by an adjacent circular band of adhesive 13 having a plurality of circumferentially spaced slits 14 which extend radially outwardly from the aperture 12 to the edge of the band 13. At its outer edge and on both sides thereof, the side cover sheet 10 is provided with circular bands of adhesive 15, 15, which are also provided with a plurality of circumferentially spaced slits 16 which extend radially outwardly from the. inner edges of the bands 15, '15 to the outer periphery of the sheet 10. It is, of course, understood that the annular bands of adhesive 13, 15, 15, are preferably each formed of the composition previously described. If desired, the several bands of adhesive on the outer cover sheet 1, core-liner 6, and side cover sheets 10, 11, maybe protectively covered with conventional release paper which can be readily stripped therefrom.

In use, the outer cover sheet 1 is wrapped around the outer surface of the coil B with the bands of adhesive 2, 3, 4, presented outwardly, and the adhesive band 5 is pressed against the band 3 to form a bonded lap-seam 17, as shown in Fig. 1. The core-liner 6 is then inserted while more or less flat within the core of the coil B and then opened out so as to conform to its inner contour. The side cover sheet 10 is then placed against'the side of thecoil B and the slit band of adhesive 15 is folded and pressed against the band .4 on the outer cover sheet 1 to form a bond therewith, and similarly the slit band of adhesive 13 is folded and pressed against the band 9 on the core-liner 6 to form a bond therewith. Since the side cover sheet 11 is similar to the side cover sheet 10, it will be apparent that the side cover sheet 11 is applied in the same manner as the side cover sheet '10. The slits 14, 16, permit the bands of adhesive 13, 15, 15', to be readily folded without wrinkling or tearing so as to insure anadequate bond between the side cover and the outer cover sheet 1 and core-liner 6, because the slits 14, 16, permit the bands 13, 15, upon folding, to separate into a plurality of segments 18, 19, so that in ithecompleted package the segments 18 are spaced from each other while the segments 19 overlap each other. In this connection it should be noted that the adjacent overlapping portions of the segments 19 will adhere to each other due to the fact that the outer edge of the side cover 10 is formed with adhesive layers 15, 15', on each side thereof. Similarly, the side cover sheet 11 forms spaced segments '20 and overlapping segments 21.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the packaging covers for coiled sheet material may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
