BLANK FOR PAPER rueEs.

Specification of Letters Patent. Application 11165 May 10, 1904. Serial No. 207,224.

Patented Jan. 15, 1907.

My invention relates to certain improve- Io ments in paper tubes, and more especially to that class ofpaper tubes empleyed in the manufacture of boxes or containers for articles of merchandise, and which are provided interiorly with a coating of paraffin or other impervious materialv and exteriorly with printed matter descriptive of the goods, &c'. In the manufacture of these tubes it is customary to roll a sheet of paper over a cylinder or mandrel and during such operation supply paste to the paper, sothat the several thicknesses constituting the body of the tube will be pasted together, the strength of the tube de ending of course upon the number of thic esses applied, and in mak- 5 ing up boxes or containers from such tubes they are in-many instances coated interiorly with paraffin, usually accomplished by dipping or by ap lication to the interior surface only. Such oxes or containers are ,then

3 sup lied with labels, either on a sheet pasted to t e box or printed directly on the outside of the box.

It is the purpose of my present invention paraffin that portion. of the' tube-blank which will form the interior ofto coat with the tube, leaving the balance of the blank so that paste can be applied thereto tounite the several thicknesses when the blank is made into a tube.

In the accompanying'drawings, Figure 1 is a face view of the sheet of'paper from which the tube is rolled, showing that side to which the paraffin and paste are applied. Fig. 2 is a similar view of the reverse side of the sheet, showing the side containing the printed matter. Figs. 3 and 4'are perspective views illustrating successive stages in the formation of the tube in accordance with my invention, and Fig. 5ris a 5 view of the completed tube.

Similar letters of reference indicate similar parts in allthe figures of the drawings.

In the drawings I have illustrated the tube perspective tainer of the conventiona be understood that in the practice of the invention the tubes will be made of suff cient length, so that several boxes orbodies therefor may becut from a single tube, and in some instances the tube may be made in of a length sufiicientfor a paper box or con- I size; but it will '55 tapered form, and polygonal instead of cylindrical. V

In carrying out my invention Itake a sheet of paper, as A, of a length and width commensurate with the size and length of tube; required. On one side of this sheet and at one end thereof, covering a surface representing the exterior of the completed tu e, terminating in the present instance at the dotted line a, as shown in Fig. 2, I print the label or other matter which is to be upon the box or container formed from the tube, leaving the balance of the'sheet, as b, referably plain. On'the other side of the s eet and at the end thereof opposite the label is a coating of arafiin, as c, Fig. 1, such araflined s ace extending the full widt the sheet and inwardly from the edge a distance corresponding to that of the inner circumference of the com leted tube, as at c, and from the, inner e ge of the, paraflined surface the balance of the sheet is coated with paste d, whichlatter may be applied either before or \during rolling the paper to form the tube;

The sheet is moundor rolled in'the usual manner, be inning in the present instanceat that end wIiich is provided with the paraffined surface and so that the first turn will bring the ed e of said sheet at the point 0, where the a esive surface (1 begins, with the parafiined surface at the inner side. In this way that art of the sheet which is coated with para tube. The sheet is then Wound to provide the operation forms the inner'surface of the the several thicknesses which are pasted toether, and the last lap or. turn of the sheet brings that part upon which the label is printed on the outer side of the'tube, it being understood, of course, that the Width of the surfaces containing the parafl'in and label equals the 'inner and outer surfaces of the tube, res ectively, while the intermediate ortion o the sheet equals exactly the num- Ber of turns orlaps it is desired the tube shall contain to give the required body thereto.

It is obvious that instead of applying the paste to that part or surface of the sheet contained, between the paraffined portion and opposite edge the same could be applied on t e other side of the sheet or the p ain surface I), or on both, inasmuch as when the sheet of paper is rolledin forming the tube these surfaces are pasted together. I lt'is also obvious that when the sheet is rolled as herein set forth no paste will be upon either the paraflined or printed surfaces, which provide the inner and outer sides of the tube, respectively.

. By my invention the blank or sheet from which the tube is formed is prepared before it 1 is woundthat is, it is provided 'with the outer coatings of ara'flin and paste and in some instances wit theprinted label. The sheets thus prepared are then wound in the usual manner to com lete the tube and rovide an inner parafiine surface and, if esired, anprinted surface, the printed matter on the latter being spaced a art to provide a label for each box when t e tube is made of such length as to provide several boxes. This results in considerable saving of time and exsenses ense in the manufacture of paper tubes for oxes or containers and also provides a better finishfor the inner and outer sides than by the usual method.

It will be understood that the sheets may be prepared from a continuous paper-roll, the opposite sides being provided with araflin aste and printed matter, as hereto ore set forth, and the tubes rolled so, that the inner surface will be coated with parafin, the several thicknesses lued together, and the outer surface of the tu e printed.

I claim- As a new article of manufacture, a blank for makin paper tubes, said blank having a portion 0 its surface coated with paraffin equal in width to the inner diameter of the tube to be formed, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
