3 Claims.

This invention relates to a pull-tab for rolls of web material and to a method of making finished rolls using such pull-tab.

In the manufacture of rolls of web material,

5 and more particularly in the manufacture of rolls of tabulating paper such as are used in machines for accounting purposes, it is generally customary to adhesively secure'the free end of the web material to the roll in order to prevent the roll from becoming unwound. The present invention comprises a pull-tab for facilitating the opening up of the pasted end preparatory to using the web material. My invention also comprises a method of applying the pull-tab in the form of strips to the rolls of web material while they are being wound, during they slitting and rewinding operation.

It is therefore an important ob-ject of this invention to provide a pull-tab of improved design for facilitating the opening of rolls of wound web material.

It is a further important object of this invention to provide a method for making finished rolls wherein pull-tabs are inserted in place prior to the rolls.

It is a further important object of this invention to provide finished rolls of wound web material having pull-tabs of improved design associated therewith for facilitating the opening of the rolls.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawing.

This invention (in a preferred form) is illustrated in the drawing and hereinafter more fully described.

On the drawing:

Figure 1 is a top plan broken View of a plurality of slit rolls mounted on a shaft, illustrating the manner of positioning a strip of pull-tabs ernbodying my invention.

Figure 2 is a topplan broken view of the same rolls as shown in Fig. 1 after the completion of the roll nishing operation.

Figure 3 is an enlarged plan View of a finished individual roll.

Figure 4 is a sectional view of the same.

As shown on the drawing:

The reference numeral IU indicates a web of paper after being slit and in the process of being wound up upon a shaft I I into a plurality of small rolls I2. The rolls I2, for instance, may be rolls pasting to the outer layer of the Web material to (Cl. 2406-59)l of tabulating paper for use on accounting ina-I chines or the like. o

In accordance with my invention, when the rolls I2 have been wound up to the desired diameter, a strip I3 comprising a plurality of gen- 5 erally triangularly shaped pull-tabs I4, is laid over the upper surface of the roll I2. The strip I3 extends the full width of the rolls I2 on the shaft II and is provided at each end with a tab I5 that projects beyond the end of the end roll to 10 facilitate handling of the strip. The end tab I5 may suitably be provided with score lines or perforations I 6 to permit ready severance thereof.

Each of the triangularly shaped pull-tabs I4 is of substantially the same width at its base as 15 the width of the individual rolls I2 rand score lines or perforations` I'I are provided for the separation of the pull-tabs along lines coinciding With the end edges of the individual rolls I2.

After the strip I3 has been positioned in place, the operator runs a paste brush over the surface of the strip intermediate the bases and apicesfof the individual pull-tabs to apply a band of adhesive I8 to the upper faces of said pull-tabs and also to the marginal portions, such as I9, of the roll surfaces intermediate the triangular portions of the tabs I4. The operator also lays a rip string 20 over the pull-tabs I4 along a line slightly below the apices 2| of said pull tabs.

After this has been done, the operator starts up the rewinder for a brief instant to wind a further portion of the web I0 upon the rolls I2, so as to overlie the rip cord 20. The cord 20 is then pulled to sever the Web along the line of the cord, thereby providing the edges 22 on the individual rolls I2. This leaves the apices 2I of the pull tabs I4 exposed beyond the end edges 22. Because of the fact that there is no adhesive on the undersides of the pull-tabs I4, the apex 2I of each tab tends to separate from the roll and to stand out a little bit, thus facilitating the grasping of the pull-tabs in opening up the rolls.

In opening a roll that has been sealed as described, the adhesived portions I9 are ruptured, thereby giving a free end of the paper on the roll With the pull-tab attached thereto. It is` then a simple matter to tear off the pull-tab and the roll is ready for use. 1

It will be understood that strips of my pulltabs may be manufactured in any desired length in accordance with the width of the particular roll with which the pull-tab is to be used. Various colorsl of paper can be used in the tabs to identify the different grades of adding machine rolls that the tabs are to be used with. Because of the fact that no glue is used on the underside of the tabs, printed advertising matter'can be placed on that side of the tabs that can be seen when the tab is pulled open.

I am aware that many changes may be made and numerous details of construction may be varied through a Wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

1. A finished roll of paper .having ajgenerally triangularly shaped pull-tab positioned inside of the outer layer of paper With an apex thereof extending beyond the end of said paper to facilitate grasping thereof, said tab and outer layer of paper being adhesively joined along a strip spaced from said apex and said outer layer being adhe-4 sively secured to the paper layer next below at the edge portions adjacent said tab edges.

2. The combination with a tightly wound roll of paper of a separately formed triangularly shaped pull tab positioned beneath the outermost Winding of said roll and having its apex freely extending beyond the end edge of said outermost Winding to provide a grasping portion, said tab and Winding being adhesively secured together only over an area spaced away from said end edge and said outermost Winding being adhesively secured to the Winding next beneath on each side of said tab.

3. The combination with a tightly Wound roll ofpaper of a triangularly shaped pull tab having a base portionrthe width of said roll positioned beneath and adhesivelysecured only to the outermost Winding of said roll and having its apex eX- tending beyond lthe edge of said outermost winding vto provide a free grasping edge, said outermostiwinding being adhesively joined to the Winding next beneath along marginal portions thereof only adjacent the edges of the apex of said tab toward the base portion thereof.
