I the accompanying drawing.

Hitherto rolls of paper and the like were protected against damage during transport by means of several layers of packingpaper wrapped around such rolls. These layers ofpacking paper were glued together, so that they formed a protective sheath on the surface of the roll, or, particularly with largerolls, they were held by strips of sheet met-a1, which were secured close to the edges. These known provisions for protecting paper rolls are, however 'very insuflicient, as they will protect the circumferential surface of the rolls only against damage, but not the face ends, and least of all the edges, which suffer most during transport. The strips of metal laid around therolls at the edges are of no avail, on the contrary, they-will even be harmful, as their sharp edges penetrate,

into the paper web, and when they are detached, they will easily tear the paper. A large number of layers of the paper will be useless, whereby a considerable wastage is caused.

The present invention relates to a protective cover fort paper rolls and the like, by which thetroubles hereinbefore stated are avoided, as the new cover will protect the outer face as well as both ends and the edges of the roll against all damages, and may, be. s1des, be easily applied and removed, withcuti) giving rise to. any injury to the paper We The present invention is exemplified in Figure 1 a perspective view ofthe same. F g. 2 1s a side view, partly in sectlon. Fig.

3 is a sectional view on an enlarged scale,

and Fig. 4 is a modification in a perspective view. 1 The roll of paper or the like a is wrapped in several layers of a web of paokmg p p I), thewidth of which is greaterthan that of the paper to be covered. This cover I) will therefore project at both'ends of the rolls to a more or less great extent. While the packing paper is being wrapped around the-roll,

' and such packingpaper is-coated in known man ner with alayer of an adhesive, so that the.

pressedclose against the ends of the roll. If

it is deemed advisable, circular disks, of pasteboard or paper d may be laid against the ends of the rolls previous to suchfolding down of the ends of the wrapper. By such means annular flanges of any desired width and formed of a pluralityof folds can be produced, and these flanges f will, afterthe adhesive has hardened and the folds have thus become fixed, form. very hard and strong protective angular covers 9 at the corners. These strong, crustlike covers 9 will completel incase the edges of the roll protect them against their being injured. The disks (i will prevent the adhesive from entering into-the -paper web, when the flanges f are pressed down against its ends. r

If the roll a consists of a web of smooth paper, the wrapper of packing paper bis made of such a width that when t e projectin'g ends are turned down and pressed against the ends of the roll, the latter are almost completely or completely covered (Fig. t); After the adhesive has dried, the

,roll will. become incased on its face as well as on its ends'within an extremely stiff sheath, which protects the web against injury, and also prevents the inner coils from slipping endwise out of the outer coils. A

w1re or cord It may be embodied in the sheath, by means of which the sheath can 'be I Y easily torn open for removing it. I claim:

A paper roll, provided with a cover that extends over the face of the roll andis'provided with a pair ofinwardlyturned' flanges that extend over the ends of the roll, each of said flanges being formed of aplurality. of

folds, and with a hardening adhesive carried by the cover, and adapted to stiffen the flanges andfix the folds thereofQ 7 In testimony whereof I hereto aflix my signature'in the presence of two witnesses.
