M ATTORNEYS Patented Sept. 14, 1943 2,329,527 METHOD OF MANUFACTURING ROLLS OF APE Edward Robert Golub, Flushing, N. Y., assignor to Atlantic Gummed Paper Corp., a corporation of New York Application January 18, 1941, Serial No. 374,971

2 Claims.

This invention relates to a method and means for sealing the ends of rolls of gummed tape, and more particularly to sealing the ends of paper tape wherein one side of the tape is coated with a water soluble glue or other suitable adhesive.

-Such gummed tapes of various widths are commonly sold in rolls and heretofore it has been customary to moisten the free end of the tape and stick it down against the body of the roll as the rolls are made up with the gummed side of the tape outward. This method of scaling is objectionable in that it is necessary to peel off one or more layers of the tape when unsealing a roll, or to use a knife and cut through the outer plies of the coil to free it, all of which causes waste and loss of time.

Heretofore attempts have been made to overcome the above difficulties by placing at or near the free end of the roll, a sealing strip-usually a piece of paper or the like-lying across the roll having slots or perforations therein lying between the free end and the body of the roll in such a manner that the free end of the tape can be torn loose from the roll, the perforated strip giving way because of its weak texture, thereby freeing the end of the roll. However, the insertion of such perforated strips in individual rolls requires time, and the instant method constitutes an improvement thereover, particularly in connection with the manufacture of the rolls.

An object of the present invention is to provide a method of securing the ends of rolls of gummed tape'to the rolls which is easily applied to the tapes when they are in web form.

A further object is to provide means for sealing the ends of rolls of gummed tape, whereby the ends are detachably secured to the rolls and may be readily pulled off the rolls without, danger of tearing the rolls and with the destruction of a minimum amount of tape.

These and other objects of the invention hereinafter referred to, will now be illustrated by disclosing the method and means for practicing the same, reference being had to the following specification and the accompanying drawing in which- Figure 1 is a sectional view of a sealing strip suitable for carrying out the method herein disclosed;

Figures 2 and 3 are sectional views of alternate forms of strip;

Figure 4 is a diagrammatic view showing how the sealing strip is applied to a web in a paper rolling machine;

Figure 5 is a perspective view of one of the paper rolls made in accordance with Figure 4;

Figure 6 is a side view of the roll shown in Fig. 5; and

Figures 7, 8 and 9 illustrate other forms of sealing strips that may be used in carrying out the method.

For the sake of illustration, the invention will be described as applied to rolls of gummed paper tape, although it is obvious that it may be applied to rolls of any material.

Rolls of gummed paper, commonly called tape, are commercially manufactured in which the tape varies from a fraction of an inch to several inches in width, and such tape is commonly used for sealing packages and the like. These tapes are commonly made on paper rolling machines, as for example that shown in U. S. Patent No. 2,050,794 dated August 11, 1936, to F. W. Humphner; several types of such machines are in use, and the construction of them is well known and is therefore not herein described in detail.

In such a machine, a web of gummed paper is unwound from a feed paper roll and is severed into a plurality of narrow strips which are wound into individual rolls of tape.

The paper used is usually gummed on one side and is so wound that the gummed side is uppermost so that these rolls can be readily employed in the usual counter sealingmachines where the gummed side of the tape is'moistened as it is withdrawn from the roll.

In Figure 4, the web above referred to is designated by the numeral In. It will be understood that the paper is coming off a feed roll positioned at the top of thefigure and after slitting, is wound on a. take-off roll at the bottom of the figure, as indicated by the numeral II, the web being severed as shown by the dotted lines at l2, to form a plurality of narrow strips or tape wound on the take-off roll.

After the tapes are formed and before the free ends are released, the sealing strip l3, which is continuous for the total width of the web It), is placed in position over the rolls andunder the end of the web next the take-off roll. This sealing strip l3 may be of any of the types hereinafter described. Its lower face rests upon the upper or gummed surface [4 of the rolls, and as the strip I3 is moistened previously to being placed in the web, it will adhere to this gummed surface. The upper surface of the sealing strip will, of course, engage the under or ungummed surface l5 of the web, and if moistened will adhere thereto, so that the sealing strip l3 forms a seal for all of the ends of all of the rolls in the web.

After being placed in position as just described, the take-up roll may be revolved slightly to carry the sealing strip slightly beyond the cut-off point, which is determined by placing a string through or across the web as shown at I3, and the rolls are wound up further and the string pulled to sever the strips. This leaves the free end l6 of each roll extending slightly beyond the sealing strip l3 and this free end can be struck down against the roll, as indicated at I! in Figure 6,

when the rolls are removed from the take-off roll or spindle.

The sealing strip is severed between the rolls in the same manner as the rolls are severed from the web.

To open a roll of tape for use, it is simply necessary to free the end 11, giving it a sharp pull which will detach the sealing strip i 3, whereupon the roll is easily unwound without tearing or loss of the layer or layers immediately under the first layer.

The sealing strip heretofore generally denoted by the numeral iii in the drawing, Figures 4 to 6 inclusive, may be of any one of the types shown in Figures 1 to 3 inclusive and 7 to 9, inclusive.

In Figure 1, the sealing strip [8 may be made of a piece of paper, such as blotting paper, which will easily tear or split. The lower surface which would normally contact With the gummed surface 54 of a roll is shown at I9, and may or may not be gummed; and the upper surface 20, which would contact with the inner ungummed surface i of the end of the roll, is gummed. The adhesive used may be of a type less adhesive than that used on the tape, so that the strip adhesive will readily give way when the end of the tape is pulled. A suitable adhesive for this purpose is that commonly used on masking tape. This may not require moistening to apply.

In Figure 2 is shown an alternate form of construction in which suitable paper or fabric layers El, 22, of the same material are provided which.

are gummed or otherwise adhesively secured together at 23, and these may be coated on one or both outer surfaces 24, 25, with suitable adhesive. When these are used in the rolls, they will part at the surfaces 23, the adhesion of which is made purposely less than the adhesion of the outer surfaces 24, 25, to the tape.

In Figure 3 is shown an alternate form of construction in which the sealing strip 26 is made of paper or the like, and may be coated on one or both sides with suitable adhesive; but instead of this adhesive extending all over both facesof the strip, it only covers parts thereof, as shown at 21, 28, 29, in Figure 7, so that for a given area of the strip the .adhesion of the strip to the roll would be less than if it were coated with adhesive over its entire surface. These strips of adhesive may be pointed toward the front of the strip 1 as shown at 30, which front lies immediately under the end l6 of the roll, so that this end 16 forms a tab which enables the unsealing of the roll to be easily accomplished as the extreme outer end thereof is not securely held to the roll. With this type of strip, only the adhesive coated portions 21, 28, 29, are moistened to make them adhere to the tape.

In Figure 8, the sealing strip may be composed of a piece of blotting paper or the like, as shown at 3|, which contacts the surface I of the roll, an intermediate layer 32 of a comparatively weak adhesive, and an upper layer 33 of comparatively stifl' paper or the like of different characteristics and greater strength than that at 3| and having the outer gummed surface 34 adapted to adhere to the inner surface l5 of the roll.

In Figure 9, the sealing strip may be of hingelike formation and consists of a single piece of paper 35 which may be moistened and applied to the gummed surface ll of the roll and to the inner ungummed surface 15 thereof, the surface of 35 applied to l5 being gummed, or all of one side of 35 may be gummed. This strip forms a seal for the end I5 of the roll, and by pulling I6, the paper 35 will tear at the crease 36; this crease may be scored or perforated to facilitate its easy separation. The outer face 31 of the strip 35 is not gummed, or if gummed, the gum is of less adhesive quality per area of surface than the gum used on the tape.

It is obvious that variou combinations of gummed and ungummed surfaces can be provided on the sealing strip, depending on whether the inner or outer surfaces of the rolls are gummed or ungummed, and that the desired result of sealing the rolls so that the ends are easily and quickly detachable, may be obtained in several ways by using the method and sealing strips constructed as herein illustrated and described.

What is claimed is:

1. The method of manufacturing rolls of paper tape which includes, the step of inserting transversely in a web of paper tape material a sealing strip adjacent to the outer or free end thereof, said sealing strip being at least as long as the entire width of said web and being of V shaped cross-section'with the open end of the V facing in the same direction as the end of said web, the further step of adhesively securing said strip to said web adjacent to said end and the body of said web, and the final step of transversely severing said material and said strip to form a plurality of said rolls.
