ROLL PROTECTOR Filed June 6, 1932 INVENTOR Valerie Blake Patented Jan. 29, 1935 of the rolls.

Such methods however have not proved satisfactory. The heavy paper wrappings are expensive and troublesome and do not protect the end or edge corners of the rolls; the windings of paper strip require special machinery to put them on and give only inadequate protection; the metallic protectors have proved even more unsatisfactory, it being practically impossible to make them tight and keep them so on the roll and they cut and tear the paper.

The objects of the present invention are to provide a protection for rolls which will have none of the faults or objections mentioned, which can be easily applied, either when the roll is finished or later, and without requiring special machinery or special skill and which will be inexpensive and will give all necessary protection to the roll.

The foregoing and other desirable objects are attained in this invention by the novel features of construction, combinations and relation of parts hereinafter described and broadly covered in the claims.

The drawing accompanying and forming part of the specification illustrates one simple practi-' cal form of the invention, but it is to be understood that the structure may be modified as regards this particular disclosure without departure from the true spirit and broad scope of the invention.

Fig. 1 is a perspective view showing a roll of paper or the like, having the protectors applied thereto, one of them being shown in process of application.

Fig. 2 is an enlarged broken sectional detail taken as on line 2-2 of Fig. 1 and showing the securing of the protector about the corner of the roll.

Fig. 3 is a broken plan of the protector strip.

Fig. 4 is a cross-sectional detail of the strip as on line 4-4 of Fig. 3.

In Fig. 1, a heavy roll of paper, or the like, is indicated at 5. The corners and end faces of the roll are the parts requiring special protection, since injury to these may affect a great number of layers, whereas injury to the surface between the ends is usually confined to simply the surface layer or layers.

The protector therefore consists of a strip 6 of cardboard or the like, secured by quick drying cement or the like, directly over the end portion Rom. nomads N a v Valerie Blake, New York,"l\l. ;Y. 1. Application June aissa-seri ino. 61;;69

' of the roll.

of the roll, wide enough to form a protecting ring of substantial extent at the end of the roll and having lobes or scallops '7, extending along one edge of the same and secured by cement or the like, over the end of the roll.

To seal the end of the roll and to furnish a continuous surface to which the scallops or segments may be adhesively secured, there is provided, in the illustration, a disc 8 of cardboard, heavy paper, or the like, of a diameter approximating that of the roll, which disc may itself be adhesively secured to the end of the roll.

The protector strip may be of a fairly heavy cardboard, relatively hard and smooth to stand the wear, but sufficiently porous to take the cement for firmly and fixedly securing the strip to the roll. The strip may be in definite lengths or segments convenient for use with standard size rolls or simply be in lengths convenient for are terminated at or-short of the bead as indicated particularly at 11, Figs. 2, 3 and 4. Particularly important is the fact that this bead gives the strip a degree of flexibility which prevents the material frombuckling, gathering, bulging or crinkling, where the flaps are folded inward from the base material. The strip is applied with the bead at the inside and this as indicated in Fig. 2, has a tendency to create somewhat of a bulge or thickening of material, directly underlying the corner, providing in effect an extra cushion of the material directly where it is needed, that is, at the extreme corner edge The strip material-may be furnished with the adhesive on the base and flap portions, ready to be moistened, or the adhesive be applied at the time of applying the strip to the roll. Usually, the end discs will be applied first as by tacking or adhesively fastening them to the ends of the roll and then the strips to the roll, as by rolling tearing of the flaps when the cuts for the scallops the roll over the same, so as to utilize the weight w of the roll for pressing them firmly and tightly in place. The end flaps may then be turned in and secured over the end discs. In the final result, the corner edges of the roll are fully Iprotected, sufiiciently to stand any ordinary handling or transportation. The ends and corners of the rolls are sealed against dirt or the like, and such sealing and protective means are attached to and form practically integral parts of the roll structure. The protectors are relatively inexpensive and they are quickly and easily applied, without having to lift or up-endthev rolls. What is claimed is: y ff 1. A roll protector, comprising a strip of cardboard, or the like, scalloped along one edge having a longitudinally extending bead defining a hinging axis for the scallops. 2. A roll protector, comprising a strip f cardboard, or the like, scalloped along one edgeand having a longitudinally extending..=-beadidefinin'gi a hinging axis for the scallops, the cuts defining the scallops terminating short of said bead? 3. A roll end protector, comprising a disc of cardboard or the like, a strip of cardboard or the like, adapted to be adhesively secured directly to the end portion of the roll and having scallops folded inward and adhesively secured to the face of the end disc, said strip having a. bead defining a hinging line formed therein and separated from the inwardly cut portions of the scallops.

41 A m1 endfprotector;comprising an end disc of cardboard or the like, a" roll encircling strip of cardboard or the like having a longitudinal "bead and scallops separate from said head seiicured over the face of the disc, the bead being disposed at the inside of the protector and adja- "cent' the'peripheral edge of the disc to form a protecting corner edge cushion for the roll.
