PRE-CUT SELF-ADHESIVE STENCIL Filed Nov. 1, 1955 2 Sheets-Sheet 2 IN VEN TOR.

BY BURTON D. MORGAN ATTORNEYS United States Patent PRE-CUT SELF-ADHESIVE STENCIL Burton D. Morgan, Painesville, Ohio, assignor, by mesne assignments, to Avery Adhesive Products, Inc., a corporation of California Application November 1, 1955, Serial No. 544,171

2 Claims. (Cl. 101128.1)

This invention relates to a stencil and more particularly to a pre-cut self-adhesive stencil for blanking out in perfect register a plurality of separate letters, art-work shapes and other areas of desired conformation (hereinafter collectively referred to as symbols) or, if desired, for wholly or partially blanking out background for such symbols.

Self-adhesive die-cut stencils are commonly provided in which protective release-coated papers enclose ad-' hesive-coated stencils having one or more separate letters or other symbols. in use, the protective coating on the back of the stencil is stripped off; the stencil is pressed against the surface to be coated; and a top protective coating, if provided, is also stripped off, leaving the stencil ready for use. When the stencil is used, discontinuous coating deposits remain as separate letters or other separate symbols. 7

The present invention provides a pre-cut adhesive stencil which enables a plurality of stencil masks to be placed in perfect register on a surface to be coated so as to cover areas representing a plurality of letters or other symbols. If desired, the present invention may also be employed to cover solid background areas, as do stencils of the prior art mentioned above. That is, the present invention may be employed to mask oif either separate or discontinuous symbols or solid backgrounds.

The invention contemplates the provision of a stencil in which display-symbol-defining lines of severance extend through two of three sheets or webs, the center web constituting an adhesive-coated stencil sheet, and the outer webs being releasable from the center web, all as more particularly set forth below.

The above and other objects and advantages of the invention will become more fully apparent from the following description of a specific example of the invention. This example is a presently preferred embodiment of the invention which will enable the art to readily practice the invention for purposes of evaluation and trial, either by duplication of such example or by changing details thereof to provide alternatives embodying the principles and teaching of the invention.

In the drawings, which are all somewhat schematic for purposes of clarity:

Figure 1 illustrates a lamination which may be employed in the invention.

Figure 2 illustrates a portion of a stencil contemplated by the invention.

Figures 3-5 illustrate stages in the use of the stencil portion shown in Figure 2.

The lamination shown in Figure l is partly separated to more clearly indicate its arrangement. The lamination comprises the webs 10, 11 and 12. The center web 11 ice may be coated on both sides with a pressure-sensitive adhesive and the inner sides of the webs 10 and 12 provided with release coatings, as indicated. Suitable web materials, adhesives and release coatings for the general purposes to which the invention relates Will be familiar to the art, and they may be similar to or identical with those conventionally used in connection with pre cut selfadhesive stencils.

it is preferred that the web 10 be more readily releasable than the Web 12. This can be accomplished by several means, such as by crinkling the web 10, all as will be familiar to the art.

The stencil contemplated by the invention comprises a lamination, such as that shown in Figure 1, which includes one or more lines of severance or die cuts, such as the die cut 13 shown in Figure 2. In the example illustrated, this die cut defines a symbol area A and penetrates into the webs 10 and 11 but not into the web 12. In the form shown in Figure 2, the stencil may be stored or shipped.

The user peels oif the portion of the web 10 corresponding to the desired stencil blanking, such as the portion of the web 10 corresponding to the symbol area A, as indicated in Figure 3. This exposes the adhesive surface of the web 11. The stencil is then placed or pressed on the urface to be decorated, such as the surface 14 of a piece of transparent glass, as shown in Figure 4. Exposed portions of the center Web 11 adhere to the surface 14. Then the stencil body is slowly removed, as indicated in Figure 5, leaving the stencil mask 15 and any other masks which may be employed in the particular design, in perfect register on the surface 14. In the illustrated example, the stencil masks will have adhesive on both sides, which adhesive acts as a barrier to paint penetration even when the web 11 comprises a relatively absorbent paper.

What is claimed is:

1. A pre-cut self-adhesive stencil comprising a lamination of three contiguous webs including a first web, a second intermediate web and a third web, a pressure-sensitive adhesive coated on said second web on the side thereof associated with said first web and releasably adhering said first and second Webs, an adhesive between said second and third webs and releasably adhering said second and third webs, at least one cut extending along a display-symbol-defining line and penetrating into said first web and into said second web and not into said third web.

2. A pre-cut self-adhesive stencil comprising a lamination of three contiguous webs including a first web, a second intermediate web and a third web, a pressuresensitive adhesive coated on said second web on the side thereof associated with said first web and releasably adhering said first and second webs, an adhesive between said second and third webs and releasably adhering said second and third webs, at least one cut extending along a display-symbol-defining line and penetrating into said first web and into said second web and, at least along a significant portion of the length of said cut, not penetrating significantly into said third web.
