DETAILED DESCRIPTION

The details of one or more embodiments of the subject matter of this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

Like reference numbers and designations in the various drawings indicate like elements.

The present invention describes a stencil tool for marking a foil, that overcomes disadvantages inherent in the known methods and systems of cutting and stenciling. The present invention provides a stencil tool that may be cost effective, time effective, and allow for marking and cutting foil in an appropriate outline such that it may be fitted to a pipe, for example, among other benefits. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved stencil tool for marking a foil, which provides the advantages and overcomes the aforementioned disadvantages.

A disposable stencil tool for marking a foil is presented herein. The disposable stencil tool comprises a flexible sheet with holes, the holes forming an outline, wherein the flexible sheet may be coupled to the foil, the holes allowing a user to mark the foil with the outline, the outline for fitting a joint between a plurality of tubular members.

A method of employing the stencil tool to mark foil is presented herein. The method comprises coupling the flexible sheet to the foil and marking the outline on the foil through the holes. In some embodiments, the method further comprises uncoupling the flexible sheet from the foil and cutting the foil along the outline forming a cut edge on an end of the foil. In some embodiments, the method further comprises fitting the cut edge into the joint and attaching the foil to at least one of the plurality of tubular members.

FIG. 1 illustrates an example of a stencil tool 100, according to some embodiments. The stencil tool 100 may have a body, flexible sheet 102, with holes 104. In some embodiments, the holes 104 may be formed to create an outline 106 of an appropriate shape. In some embodiments, the stencil tool 100 may be temporarily fastened with a flexible sheet 102 coupled to a metal foil, wrapping around the metal foil, such that markings may be made through the holes 104, indicating to a user where said user may cut on the metal foil. Said user may remove the stencil tool 100 and cut the metal foil along the markings of outline 106 on the metal foil. After the stenciling and cutting has been completed, the cut metal foil may be placed onto a T-pipe or rolled onto a pipe portion or pipe joint as may be needed, in some embodiments. The stencil tool 100 may have standard cut outlines for common pipe joints, some of which are shown below in some example embodiments.

As a non-limiting example, an insulation installer may wish to fit metal foil around the insulation on a T-pipe. This may be to protect the insulation, for instance. Said user may temporarily fasten or couple a stencil tool 100 to the metal foil, wrapping the flexible sheet 102 around the portion in which the user wishes to cut. Using a pen or a marker, for example, said user may mark through holes 104, marking out outline 106 on the metal foil. Said user may uncouple the stencil tool 100, and use said markings to cut along the outline on the metal foil, such that the metal foil may be fitted around the insulation on the T-pipe. Said user may cut along the created outline on the metal foil by hand or may use a machine.

In some embodiments the stencil tool 100 may be used for insulation, as an example, across many different types of pipes, 90 degree, 45 degree, among other joints. In some embodiments, the outline 106 may be different shapes to accommodate such different types of pipes, and pipe joints.

The stencil tool 100 may allow metal foil, among other materials, to be cut much more quickly than traditional methods, around thirty minutes in many cases, for example. In some embodiments, the stencil tool 100 may provide such ease-of-use that an apprentice of an insulation installer may use said tool to cut metal foil, such that the metal foil may fit properly to insulation around a joint.

In some embodiments, the stencil tool 100 may be used on a flat surface, such as non-rolled sheet-metal. However, in a typical job site of an insulation installer for example, the metal foil may already be rolled. The stencil tool 100 may be flexible, so that the flexible sheet 102 may be wrapped around the metal foil. In some embodiments, the stencil tool 100 is constructed from recyclable materials. In some embodiments, the stencil tool 100 is constructed from compostable materials.

FIG. 2 illustrates a stencil tool applied to mark a metal foil 200, according to some embodiments.

In some embodiments, the stencil tool 100 may be coupled to an outer-side of a metal foil 202, where the stencil tool 100 wraps around the metal foil 202. This may allow a user to mark, through the holes 104 onto the metal foil 202, an outline 106.

FIG. 3 illustrates a marked metal foil 300, according to some embodiments. In some embodiments, a stencil tool 100 for example, may be used to mark metal foil 202 with an outline 106, as shown with a stencil tool applied to mark a metal foil 200 in FIG. 2.

In some embodiments, the metal foil 202 may be marked, forming a marked outline 302 which may be in a similar or a same shape as the outline 106 used to create the marks. In some embodiments, the metal foil 202 may be cut along the marked outline 302, for example.

FIG. 4 illustrates a cut metal foil 400, according to some embodiments. Metal foil 202 may be cut, along the marked outline 302, for instance, creating a cut edge 402, forming a desired shape, such that the metal foil 202 may be fit to a T-pipe, for example.

FIG. 5 illustrates a metal foil fitted on T-pipe 500, according to some embodiments. In some embodiments, cut metal foil 400 may be fitted on a T-pipe 502.

As a non-limiting example, a user may have selected a stencil tool 100 with an appropriate outline 106 for proper fitting to a T-pipe, such as T-pipe 502. Said user may have used said stencil tool 100 to mark and cut a metal foil 202 along marked outline 302, creating cut metal foil 400. Fitting cut edge 402 into a joint as appropriate, cut metal foil 400 may then be attached to cover and protect insulation on a T-pipe 502, for instance.

FIG. 6 illustrates a front view 600 of a metal foil fitted on a T-Bar, showing an example foil cut shape, according to some embodiments. Cut metal foil 602 may, in some embodiments, have 90 degree fitted cut edge 604 such that cut metal foil 602 may be attached with a proper fitting to a T-pipe 606.

FIG. 7 illustrates a front view 700 of a metal foil fitted on a T-Bar, showing an example foil cut shape, according to some embodiments.
