As can be seen from
Preferably, the magnetically-attractive substrate 20 also comprises a top layer 24 of a resilient or other material that is well-suited to produce a clean cut in the material, when a sharp edge, such as that of a cutting wheel 26, is applied. A material that is particularly well-suited as the top layer 24 is the material of a conventional self-healing craft mat. It is preferred that the top layer 24 be bonded or otherwise attached to the magnetically-attractive material 22 of the substrate 20. Such a substrate is another aspect of the apparatus according to the present invention.
The present invention will be described further with reference to only the pattern 12, it being understood that the description also applies to the pattern 14 and to other patterns that are not illustrated. The magnetically-attractive material 22 defines a magnetically-attractive area that is at least as large as the area of the pattern 12 with which the substrate is being used. The magnets 18 are adapted to hold the material 16 to be cut and the pattern 12 to the magnetically-attractive area by magnetic attraction. In this regard, it is important that each magnet 18 be strong enough to hold the pattern 12 and the material 16 firmly. Like the magnetically-attractive material 22, the top layer 24 has an area at least as large as the area of the pattern 12.
As can be appreciated from
The kit 30 can have a plurality of the substrates 20, or substrate sections, that can be used individually or secured together along their edges to form a single substrate of larger area. For such securing, the kit 30 can include clips or other conventional fasteners (not shown). Where the kit 30 has a plurality of substrates 20, all of the substrates can have the same shape and size, for example, a rectangular shape of about 3 feet by 4 feet, or the substrates can have differing sizes and/or shapes. The kit can also include a cutting tool 26, such as a cutting wheel. Packaging 34 can hold together all of the parts of the kit 30 for sale and storage. In the illustrated packaging 34, a plurality of the substrates 20 can be held one in front of the other such that only the front substrate is visible, especially where all of the substrates 20 are of the same size and shape.
The present invention also relates to a method for cutting material in connection with a pattern. In accordance with the method, which, for convenience, is described in connection with the apparatus disclosed herein, material 16 to be cut is put on, and spread out on, a substrate 20 having a magnetically-attractive area, defined by a magnetically-attractive material 22, that is at least as large as the area of a pattern 12. The pattern 12, which can be a conventional sewing pattern made of thin paper, is spread out on the material 16 such that the magnetically-attractive area underlies the entire pattern, with the material to be cut interposed between the pattern and the magnetically-attractive area. When the material 16 and the pattern 12 are spread out and smooth, magnets 18 are positioned on the pattern 12 to restrain movement of the pattern and the material relative to one another and relative to the substrate 20. The magnets 18 are positioned near the edges and corners of the pattern, and in spaced relationship with one another. The magnets 18 are typically positioned such that the edge of each magnet that is the closest to the edge of the pattern 12 is about ¼ inch to 1 inch from the edge of the pattern. Then, the material 16 is cut by pressing a cutting edge, such as that of a cutting wheel 26, into the material and moving the cutting wheel along the outline provided by the pattern 12, while the material is supported by the substrate 20. The substrate 20 can have a second material 24 adapted to receive a cutting edge in a manner that results in an even cut in the material to be cut, in which case the pattern 12 is preferably placed entirely on the second material.
It will be apparent to those skilled in the art and it is contemplated that variations and/or changes in the embodiments illustrated and described herein may be made without departure from the present invention. Accordingly, it is intended that the foregoing description is illustrative only, not limiting, and that the true spirit and scope of the present invention will be determined by the appended claims.
