' MARKING TAPE Filed Oct. 5, 1955 Y INVEN TOR.

ELIZA BETH KRUMMEL PARKER & CARTER ATTORNEYS United States Patent MARKING TAPE Elizabeth Krummel, Milwaukee, Wis.

Appiieation October 5, 1955, Serial No. 538,699

Claims. (Cl. 33174) My invention relates to improvements in marking tape and more particularly an adhesive tape employed to guide the operator of a sewing machine.

It is manifest to any one familiar with the art of sewing garments or the like on a sewing machine, that it is sometimes quite difiicult to maintain a desired straight or curved line, or path when guiding the rapidly actuated needle.

An object of my invention is to provide an improved tape which may be adherently applied to the surface of a fabric being sewn, so that longitudinal lines thereon may act as a guide.

A further object of the invention is to provide severable sections of the tape which may be selectively removed from the tape to enable the latter to be disposed in varying straight or arcuate lines when applied to the fabric, to form guide lines arranged to any desired form or contour.

The tape is simple to manufacture, is easily applied and is economical for use on any fabric.

Other and further objects of my invention will become more apparent as the description proceeds, when taken in conjunction with the drawing in which:

Figure 1 shows a section of one form of tape having longitudinal guide lines, and transversely disposed indicating marks along the edges thereof.

Figure 2 shows a section of a modified form of tape having scored transverse lines in angular relation to each other and extending inward from one edge to form a plurality of readily severable V-shaped sections, and showing one of such sections removed.

Figure 3 is a view of the tape shown in Figure 2 with a plurality of sections removed to enable the tape to be shaped to an uneven curve.

Figure 4 is a view of the tape of the form shown in Figure 2, but with the tape formed to curve in the opposite direction from that shown in Figure 3.

Figure 5 is a View similar to Figure 2 excepting that the severable or scored lines extend the full width of tape, and show one section removed.

Figure 6 is a view of the tape shown in Figure 5 with certain sections removed on opposite sides.

Figure 7 shows a portion of the tape of the form shown in Figure 5 with sections on opposite edges removed to provide uneven curves in both directions, and

Figure 8 is a perspective view of the tape rolled on a core, showing the manner in which one end of the tape may be removed from the roll.

Referring now to details of the embodiment of the invention, the character 10 shows a tape body, which is preferably constructed of a suitable thin transparent or translucent material such as plastic, and is provided with a coating of adhesive material on one surface. The other surface of the tape has longitudinal lines 11, 11 imprinted thereon. These lines may be spaced at any desired distance apart from one another, and transverse indicating marks 12 may also be placed at predetermined spaced relation along the edges, or at any other convenient location.

The tape to be adherently applied to the surface of the ice fabric to be sewed so that the longitudinal lines 11 enable operator to guide the needle of the sewing machine in a straight path. The indicating lines 12 along the edges will enable the operator to determine the length to be sewed. The tape may also be employed as a guide in a similar manner while sewing a garment by hand. After sewing the tape may either be left in place on the fabric, if desired, or can be readily removed by tearing the tape along the line of stitching.

In the modified form of tape shown in Figure 2, a plurality of readily

severable lines

13, 13 formed by scoring or perforating the tape material, extend at alternate angles inward from one edge, to V-shaped points 14 adjacent the opposite edge. This permits portions of the tape to be disposed along substantially straight lines, by leaving the V-shaped sections integral, and to be shaped to any desired curve, by removing certain other sections along the scored V-shaped lines 13, as shown at 15.

In Figures 3 and 4 I show the scored lines 13 extending from one edge to the other and being joined by short longitudinal scorings 16 near the apex of the lines 13 adjacent each edge of the tape. The arrangement of the scored

lines

13 and 16 facilitates removal of

sections

17 and 18 short of the apex of each removable section, so as to insure a strong remaining edge portion of the tape, when desired, as shown in Figure 4.

Figure 8 shows how a length of the tape 10 may be rolled upon a core 19, to permit one end 21 of the tape 10 to be served at any predetermined length for the convenience of the user.

Although I have shown and described certain embodiments of my invention, it will be understood that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.

I claim:

1. A marking tape for sewing consisting of a strip of thin translucent flexible sheet material, having adhesive material on one surface thereof, and a plurality of longitudinally disposed guide lines visible from the opposite face thereof, said tape also having a plurality of readily severable lines extending transversely at alternate angles from an edge thereof to form V-shaped sections selectively removable from the tape.

2. The structure of claim 1 wherein the severable lines are produced by scoring the material.

3. The structure of claim 1 wherein the transversely extending lines extend partially across the entire width of the tape, and terminate at a V-shaped point adjacent the opposite edge.

4. The structure of claim 1, wherein the transversely extending lines form V-shaped severable sections alternating at opposite edges of the tape.

5. The structure of claim 1 wherein longitudinally extending, readily severable lines are also provided closely adjacent and within the apex of the V-shapcd transverse lines, to permit selective severance of the V-shaped sec tions short of the edge of the tape, adjacent the apex of adjacent severable transverse lines.
