Filed July 10, 1967, Ser. No. 652,664 1 Claim. (Cl. 24-17) ABSTRACT OF THE DISCLOSURE A band of corrugated paperboard adapted for wraparound restraining engagement with rolled sheet building material such as laminated counter tops or the like for compact shipping, storage or display purposes, and for protecting the edge of the material so rolled and confined.

This invention, a packaging band, relates to an improved method of packaging, handling and displaying of laminated counter top sheets and other sheet building materials having similar physical characteristics. Sheet material, such as the indicated laminates are customarily shipped from the factory, packaged flat, several sheets of like size in each corrugated cardboard container. From the distribution point to area of final use, the need generally, is for only one sheet. Factory shipping of one sheet to the carton would be expensive, a waste and added bulk. A need then exists for packaging and handling convenience, personnel safety and material protection during transportation to the point of usage.

The physical characteristics of laminate sheets, of size common to the industry, include being springy, fragile, awkward to handle and easily marred by abrasion or inadvertently cracked by excessive bending, however they can be formed into a roll by moderate hand pressure. A second person can then tie the roll with string. The spring tension of the laminate sheet against the string, during transport, tends to saw on the exposed edge plus abrading the exposed surface contact points. Wire or metal is more severe. Tape, often used, is awkward to apply and for safetys sake should encompass the roll at two or more points. Upon removal the residual gum left on the surface is a problem, improper cleaning can result in material damage.

Laminates also have a critical bending moment, however this varies considerably throughout the many brands and grades. If the periphery of a rolled sheet of laminate is reduced to a diameter below the critical point, the sheet cracks and is normally suitable only for scrap. Each brand manufacturer is aware of the limits of his specific product.

The objects of the invention are:

To provide a packaging band of the character described of predetermined inside diameter somewhat exceeding the critical bending moment of the rolled material, and wherein the tensile strength of the packaging band may vary in accordance with the expanding forces developed by the rolled material being dealt with.

To provide a packaging band of the character described which is made of the usual corrugated paperboard characterized by a single flat outer face and a flat inner face with an intermediate layer of paperboard formed in alternate convolutions throughout the length and width of the band whereby a cushioning effect is provided for the area of the material surrounded by the band.

The foregoing and other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter "ice described and claimed, reference being had to the accompanying drawing forming a part hereof and in which:

FIGURE 1 is a perspective view of a packaging band made in accordance with our invention,

FIGURE 2 is an elevational view of rolled laminated sheet building material confined Within the packaging band,

FIGURE 3 is an end elevational view of FIGURE 2, and

FIGURE 4 is a perspective view of the packaging band folded into compact form for shipping or storing purposes.

Referring now more particularly to the drawing wherein like reference numerals designate like parts, the packaging band indicated generally at 10 and transversely scored to form a fold line 12, is made of corrugated paperboard comprising inner and outer flat strips or faces 13 with an intermediate sheet of corrugated material as shown.

To one end of the band 10 is secured one edge of an adhesive fiap 14 adapted for adhesive securement to the opposite end of the band for securing the same in firm circumscribing engagement with the rolled sheet of building material 11 as shown in FIGURES 2 and 3.

From the foregoing, and with particular reference to FIGURE 3, it will be apparent that the exposed outer edge 15 of the rolled sheet material 11 will be protected against cutting, tearing, breaking or other damage it would be subjected to if rolled and confined by a single strand of wire such as has been heretofore widely used for such purposes.

From the foregoing description of this device the advantages of application and use can be readily understood. It will be seen that we have provided a simple, inexpensive and efiicient means for the solution of a vexing problem of the manufacturers, distributors and users of the indicated type of building material.

While we have shown a particular form of embodiment of our invention, We are aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention.

Having thus described our invention, what we claim as new and desire to protect by Letters Patent is:

1. A band for restraining rolled sheet building material in package form, against expansive forces of the material,

said band comprising a strip of corrugated paperboard having an inner and outer layer of fiat material with an intermediate corrugated layer of the same material,

means interconnecting the ends of said band,

said band with its ends interconnected adapted for compressive peripheral engagement with said rolled material, and

one of said layers having at least one transversely disposed fold line impressed therein whereby to facilitate folding the band into compactly arranged overlying sections when removed from said rolled material.
